How To Succeed At Seed-Starting

It’s easy to buy seedlings, but there are many reasons why you may wish to start your own plants. By starting your own seeds, you have a much greater selection of flowers, vegetables and herbs to choose from. For example, old favorites like hollyhocks and less common varieties of herbs and perennials as well as heirloom vegetables might not be available as plants, or stocks may be limited. Plants with fine seeds should also be started indoors because they can easily wash away in the rain and they may have a difficult time competing with weeds. Starting your own seeds can also help you extend the growing season so you can enjoy a longer, more productive harvest. So why not get started today?

Containers for Starting Seeds

Traditionally, seeds are started in flats or peat pots. There are various sizes of plastic trays, cedar flats, peat pots and the popular Jiffy-7, a flat, peat-moss wafer, available. When moistened, the Jiffy-7 expands to form a small, self-contained pot of soil into which a seed is sown directly. This is an excellent choice when sowing seed of plants that do not like their roots disturbed during transplanting. You might also use eggshells or folded newspaper pots to start your seeds.

Seed-Friendly Soil

It is best to use a light, soilless mix when starting seeds. These mixes are sterile, meaning young seeds do not have any weed seeds to compete with, and there are no harmful bacteria, insects or other pests in the soil right away. Good seed mixes also contain adequate nutrients to carry seedlings through until transplanting. Do not use garden soil, as seeds will not germinate well in the heavy soil, and a fungus disease called damping off is common.

Temperatures for Seeds

Most seeds require warm soil in order to germinate. You will need to heat the soil of the seedling flats with a heat mat, heat tray or heating cable. Seed trays can also be placed on top the refrigerator or hot water heater. Do not put seed-starting trays on a windowsill; nighttime temperatures are too cool to allow for good germination. Seeds need consistent warm temperatures of 75 degrees or warmer for optimum germination.

Seed Watering Needs

Seeds need to be kept constantly moist in order to germinate. Moisten the soil thoroughly before planting. Water when the surface is dry with a misting nozzle or plastic spray bottle until the soil is saturated. The medium should be constantly moist, but not soggy. It is important not to overwater, which could drown the seeds and tender seedlings, but also not to permit the flat to dry out.

Sowing Seeds

Seeds should be sown 2-10 weeks before the last spring frost date. Your seed packet will provide this information as sowing dates can vary for different plant varieties or even cultivars of the same plants. Fill your containers almost to the top with moist growing mix. Tamp it down gently and smooth it out. Gently press the seeds into the mix or simply set them on the surface of the soil and place milled sphagnum moss over the top to prevent damping off. Cover the container loosely with plastic wrap or a clear dome, which will help preserve moisture and warmth. Be sure to label your containers with plastic or wood plant stakes and write the plant name and the date sowed. Set trays in a warm spot and check daily to keep evenly moist.

Seedling Care

Once seedlings have grown a half-inch or so, you should water less frequently. Let the soil dry slightly between watering, which will help the seedlings stretch and develop a strong root system. Seedlings will also need light and the best method is to use the traditional fluorescent fixtures or the new energy-saving LEDs. Suspend lights just an inch or two away from the plants. Lights must be on at least 14-16 hours a day. As your seedlings grow, raise the lights accordingly so they do not bump into the lighting fixture. If your seedlings do not get enough light, they will become weak and spindly. Fertilize seedlings weekly with half-strength, balanced, organic fertilizer. A fish and seaweed blend works well. Thin seedlings if they become overcrowded, choosing the healthiest, strongest seedlings to save.

Hardening Off and Planting Out

When the weather is warm, move your seed trays outside gradually over a 5-7 day period. Start by putting them out just for a few hours during the late morning to mid-afternoon, and then gradually increase until they are left out all day and night. Keep them in a lightly shaded, protected spot during the day to prevent sunburn. After a week or two of this transition, gently transplant seedlings into the garden. Try not to handle the root ball too much, as they are quite fragile. Water thoroughly after transplanting and again every day for about a week. Newly set out plants will look sparse at first, but they will grow and fill in quickly, leading to bumper crops and a lush, delicious harvest!

Acid-Loving Plants

Soil pH is a critical factor for gardening success. Some plants thrive in neutral soil while other plants prefer soil on the acidic side. The difference lies in the plant’s ability to use nutrients present in the soil. For plants that prefer an acidic soil a critical nutrient is iron. Iron is most easily available in soil with a pH of around 5.5. Without iron, acid-loving plants will turn yellow and suffer stunted growth.

What is pH?

pH stands for “potential hydrogen ions” and is the measure of acidity or alkalinity. The pH scale ranges from 0 to 14. pH less than 7 indicates acidity, pH greater than 7 indicates alkalinity and 7 is neutral. Soil pH directly affects nutrient availability. Plants grown in soil with pH above or below their optimum range will be less vigorous, more susceptible to disease, less able to fight off insects and may even be weakened to the point of death.

How pH Affects Plants

Nutrients necessary for healthy plants are divided into three categories: primary nutrients, secondary nutrients and micronutrients. Primary nutrients are (N) nitrogen, (P) phosphorus and (K) potassium. These nutrients requited in the largest amounts for plant growth and health and are represented in numbers found on every fertilizer container (for example, 20-20-20). (Ca) Calcium, (Mg) magnesium and (S) sulfur are secondary nutrients that are also required by plants. These are required in lesser amounts than N-P-K but are also essential for good plant growth. (Zn) zinc and (Mn) manganese are examples of micronutrients. Micronutrients are required by plants in very small amounts. Most secondary and micronutrient deficiencies are easily corrected by keeping the soil at the optimum pH value.

Because pH directly affects nutrient availability, acid-loving plants develop iron chlorosis when grown in soils that are too alkaline. Iron chlorosis is often misdiagnosed as a nitrogen deficiency because both present with a yellowing leaf. Chlorosis of young leaves is the first symptom of iron deficiency, while a magnesium deficiency results in yellowing of older leaves first. Nitrogen-deficient plants will not only have yellow leaves but also weak stems, underdeveloped leaves and reduced root development.

What Causes Soil Acidity

Soil pH is influenced by the kind of parent material from which the soil was formed. Rainfall also affects pH. As water passes through soil it leaches basic nutrients such as calcium and magnesium from the soil, which are replaced with acidic elements such as aluminum and iron. For this reason, soils formed under high rainfall conditions are more acidic than those formed under dry conditions. Caused by pollution, acid rain also has an influence in soil pH. The application of fertilizers containing ammonium or urea speed up the rate at which acidity develops in the soil. The decomposition of organic matter will also add to soil acidity.

Testing and Adjusting Soil pH

Before planting any plant it is best to know the optimum pH range that plant will thrive in and the pH of the soil in which you will be planting. “The right plant in the right place” is always the best policy. Purchase a pH test kit or meter. These are available at most garden centers, or you may also send a soil sample to your county extension service. This will give you a more in-depth soil analysis along with the pH. To correct soil pH it is imperative that you know the soil pH before you attempt to change it.

Adding shredded pine needles, composted oak leaves or peat moss will assist in lowering soil pH over time. A quicker fix is the addition of two materials commonly used for this purpose: aluminum sulfate or garden sulfur. Aluminum sulfate will change the soil pH instantly because the aluminum produces the acidity as soon as it dissolves in the soil. Garden sulfur requires some time for the conversion to sulfuric acid with the aid of soil bacteria. The conversion rate is based on the fineness of the sulfur, the amount of soil moisture, soil temperature and the presence of bacteria. Based on these factors, the conversion rate of sulfur may be very slow and could take several months for a full effect. Acidifiers should be worked into the soil after application to be effective. Do not apply to leaf surface or burn may result. Read and abide by manufacturer instructions when applying.

Keep in mind that it takes time to alter soil pH and your soil will tend to revert to its old pH over time, necessitating repeated treatment. Attempting to change soil pH too quickly may shock and kill a plant. A good rule of thumb is to adjust no more than one point per season. It is also important to note that fertilizers recommended for acid-loving plants do not assist in adjusting the soil pH, but are instead formulated to work well in already acidic soil.

Endless Summer® Hydrangeas

Do you love the look of large, stunning hydrangeas? Do they evoke wistful images of summer and floral nostalgia? Don’t you wish they would last longer in the landscape? Unfortunately, many hydrangeas have relatively short bloom cycles, but there are amazing cultivars you can investigate that provide longer lasting blooms without losing any of their beauty or richness as the season progresses.

Endless Blooms, Color and Summer Luxury

Endless Summer® The Original and Endless Summer® and Blushing Bride® are the first mophead (large, ball-shaped flower) hydrangeas that bloom on both old and new growth, providing you with beautiful flowers and gorgeous color all season long. Young plants produce blooms that are 4-6 inches wide, while mature plants can have blooms as large as 8-10 inches wide, making these massive hydrangeas real show stoppers in your landscape or garden. Flower color for Endless Summer® The Original ranges from shades of blue through shades of pink, depending upon the pH level of your soil. Pink blossoms are the result of alkaline soils (pH 6-7), while more acidic soils (pH 5-5.8) will cause the plant to produce blue flowers. Adding Master Nursery Hydra Blue or other acidifying agents to the soil can help produce the lovely blue colors if your soil is initially alkaline, or you can adjust bloom color throughout the season for a vibrantly changing show. Endless Summer® Blushing Bride, as its name implies, initially offers pure white blossoms that mature to a sweet, pink blush or pale blue tinge, again depending on the soil pH.

Large, deep green leaves provide a lovely background for these spectacular flowers, which are excellent for cutting for fresh arrangements and for drying. Endless Summer® hydrangeas mature at 3-5 feet in height and width and are perfect used as standalone specimens, planted in borders or as hedges, massed under deep-rooted trees or even set in large containers. These plants perform best in partial shade with moist soil. Another big plus for Endless Summer® hydrangeas is the fact that they are cold hardy to Zone 4, giving northern gardeners a beautiful plant that will bloom well year after year.

Perfect for Mother’s Day, Father’s Day, weddings and house warming celebrations, potted Endless Summer® hydrangeas make beautiful gifts that will provide years of beauty and enjoyment. If you already have these stunning blooms in your yard, consider cutting a few for a bouquet and share the joy with friends, neighbors, family members, coworkers and acquaintances, and the interest in these amazing hydrangeas will continue to spread until the world is blooming all summer long.

Summer Sizzles With Crocosmia

There is an excellent assortment of bulbs available for planting this time of year that promise a bounty of summer blooms. The thing is, many of these bulbs are not winter hardy. This can create a predicament for gardeners anxious for easy summer flowers but short on time and space to dig and store tender bulbs. Crocosmia can be the answer.

Introducing Crocosmia

Native to South Africa, Crocosmia – also known as montbretia, coppertips or falling stars – sizzles all summer long in colors of yellow, orange and red. The numerous small florets are tubular in shape and borne along a long, gracefully arching stem rising above sword-like foliage. Together, this formidable combination creates exotic elegance sure to be a showstopper in the garden or landscape. Hummingbirds and butterflies also find it irresistible when in bloom, and the fall seedpods are delectable for many seed-loving finches and sparrows.

Planting Crocosmia

Plant Crocosmia corms now, while they are available. Plant them in well-drained soil in full sun, 2-3 inches deep and 8-10 inches apart. A south-facing location is best, or in colder regions, add Crocosmia next to a wall that will help warm the soil. The pointy side of the bulb should be facing up. Place a handful of bone meal in the planting hole and water the soil well when done planting. These are drought-tolerant flowers, but supplemental water will still be welcome in extremely dry conditions.

Crocosmia look best when planted en masse. A grouping on either side of a sunny entrance way can be stunning, and they look equally fetching when tucked into the perennial border. This plant performs well in containers and makes an excellent cut flower – in fact, cutting the flowers will encourage even more beautiful blooms to form.

Blooms will first appear in May or June and will continue blooming throughout the summer. Flower spikes can stretch 2-3 feet tall, adding a bold burst of color to the landscape. Even without the flowers, the blade-like foliage is attractive, and some cultivars show pleats or rippling for more textural interest.

After flowers have finished blooming, simply snip off the faded flower stalks. Leave the foliage to fade naturally as you would with any other bulb. These leaves continue to produce food to provide nourishment for next year’s flowers. Leaves may be cut back to the ground once they are completely yellow, and a thick layer of mulch should be added for winter protection. Once established, these bulbs are winter-hardy and will return year after year to heat up the spring and summer with their gorgeous colors and forms.

Edible Flowers

Flowers aren’t just for beautiful dining table centerpieces anymore! For all you “foodies” out there, who also love flowers, are you aware that there are numerous blooms that are not only edible but also delicious? Flowers make a striking, colorful, textural and flavorful addition to soups, salads, baked goods and more.

Safety First

There are just a couple of things to keep in mind when experimenting with unfamiliar flowers. Not all flowers are edible and some can be poisonous, even in small tastes. Be certain to clearly identify your flowers and accept no imposters, as some blooms can look very similar. Also, it is best to use flowers that have not been sprayed with chemicals – either fertilizers or pesticides. The best way to avoid both of these issues is to grow your own edible flowers from seed, keeping them conveniently in a kitchen container garden or safely on a deck or patio where there’s no risk of contamination or misidentification.

Favorite Edible Flowers

There are surprising blooms that can be tasty accents to your favorite dishes. For the best flavor and freshness, harvest blooms at their peak early in the day. Younger and older blooms or blooms of different sizes often have subtly different flavors, so be sure to experiment to find your favorites.

Bee Balm (Monarda didyma) – Tea-like flavor, flowers in white, pink, red and lavender
Borage (Borago officinalis) – Cucumber-like taste, flowers in lavender, purple and blue
Calendula (Calendula officianalis) – Peppery taste, flowers in yellow, orange and gold
Chive (Allium schoenoprasum) – Onion flavor, flowers in white, pink and lavender
Nasturtium (Tropaloum majus) – Peppery flavor, flowers in white, yellow, orange and red
Pineapple Sage (Salvia eleagans) – Sage flavor with pineapple undertones, flowers in scarlet
Pinks (Dianthus spp.) – Clove-like flavor, flowers in white, pink and red
Red Clover (Trifolium pretense) – Sweet tasting, flowers in pink and red
Signet Marigold (Tagetes tenufolia) – Citrus taste, flowers in white, yellow, gold and red
Viola or Pansy (Viola spp.) – Sweet flavor, flowers in a multitude of colors

Not sure which recipes to try? Flowers make surprising accents to salads or garnishes for cakes, cookies and ice creams. Add flower petals to a favorite drink, or freeze blooms in ice cubes for colorful cooling. There are even recipes available for sauces, salsas, marinades and more, all with more taste and color thanks to edible flowers. Bon appétit!

Caution in the Garden… Chlorosis

Yellow means caution, even for plants. While leaf yellowing, known as chlorosis, may be a signal that there is a problem that requires attention, it may also be normal. Understanding when this coloration is to be expected and when it indicates a problem is essential to be sure you’re giving your plants the proper care.

The Good and the Bad About Chlorosis

Chlorosis is the scientific word used to indicate the full or partial yellowing of plant leaves or stems and simply means that chlorophyll is breaking down. There are times when this is normal, expected coloration, and there are times when it indicates deeper problems that need attention.

Normal Chlorosis – Yellowing leaves at the base of an otherwise healthy plant is normal; the plant is simply utilizing the nitrogen and magnesium for exposed leaves near its top rather than older, lower leaves. These yellowed, older leaves will eventually shrivel and fall off as newer growth emerges at the top of the plant.

Chlorotic Response to Light – Moving a plant from full sun to shade, or visa-versa, can cause yellowing leaves as the plant reacts to the change and stress. Make sure that you grow and maintain your plant in the proper light. Also bear in mind seasonal changes that may affect how much light a plant is exposed to, even if it hasn’t been moved.

Chlorotic Response to Moisture – Sudden changes in soil moisture may damage or kill plant roots which can lead to yellowed leaves as the roots are unable to take up sufficient moisture. Most otherwise healthy plants, however, are able to grow new roots as they readjust. Maintain correct soil moisture or move the plants to a more favorable environment.

Mineral Deficiency – A shortage of some key mineral nutrients will cause chlorosis in plants. Often, a yellow leaf indicates a lack of nitrogen, however, magnesium, iron, sulfur or manganese deficiencies are indicated by yellowing leaves with prominent green veins. A magnesium deficiency will manifest itself in the yellowing of older leaves. On the other hand, an iron deficiency presents itself in the yellowing of new or young leaves. A simple soil analysis will let you know what minerals or trace elements your soil is deficient in.

Soil Factors – Although essential and trace elements may be present in the soil, many other factors affect how the plant uses and absorbs them. If the soil pH is too high/low or there is too much salt in the soil, the plant will not be able to utilize the available nutrients. Test your soil pH and adjust as necessary to be sure the plant can absorb nutrients appropriately to maintain proper foliage colors.

Toxins – Although this doesn’t happen frequently, pollutants like paint, oil, chemical solvents, airborne herbicides or pesticides or other pollutants may cause leaves to turn yellow and dark brown before dying. In this case, remove and dispose of the plant and its surrounding soil, and mark the area to be sure it can be treated appropriately and no other plants are inadvertently exposed to the toxins.

It can be alarming to see healthy plants suddenly yellowing, but by understanding chlorosis and how it happens, you can take steps to determine the cause of the color change and what to do to help your plants recover.

Planting Basics – Trees & Shrubs

Are you ready to add trees and shrubs to your landscape? You don’t need to hire professionals to do the planting when you learn the basics of doing it the right way yourself.

Soil Preparation

How quickly and how well trees become established once they are planted is affected by the amount of stress they are exposed to before and during planting. Minimizing planting stress is the goal of proper planting. Trees and shrubs should also be thoroughly watered prior to planting to minimize water stress.

Ideally, soil preparation should be carried out well ahead of planting. Preparation could include incorporating organic matter into the soil to improve aeration, assist drainage of compacted soils and improve soil nutrient-holding capacity. Specific preparation may be needed if the soil has an inappropriate pH or is lacking in certain elements. Trees and shrubs with a limited soil tolerance range may require very specific soil preparation to meet their requirements.

Additional soil preparation is essential when you are ready to plant trees and shrubs. Dig the planting hole 50 percent wider but only as deep as the root ball. Prepare soil by mixing one-third existing soil, one-third organic matter and one-third topsoil.

Planting Container-Grown Trees & Shrubs

When you buy a plant from a garden center or nursery, it often comes in a small pot that holds the roots. Remove the plant from that container gently, but without pulling on delicate stems or foliage. Squeezing the container all around can help loosen the root ball so it slides out more easily, or the container may be thin enough to cut away.

Because the plant was grown in a container, its roots have been restricted by the shape of the container. Loosen the roots all the way around, even on the bottom. If the root system is too tight to loosen with your fingers, cut through roots slightly with a knife or pruning sheers. Make three or four one-inch deep cuts, then gently pull the roots apart.

Center the plant in the prepared hole, keeping it 1-3 inches above grade. Keep roots spread out.

Planting Field-Grown Trees & Shrubs

If you are transplanting a tree or shrub that has been field grown, it may have bare roots or be lightly bagged or burlapped. Center the plant in the prepared hole 1-3 inches above the grade. Cut and remove all cords or twine from the root ball and trunk. Burlap should be left on, but loosened and pulled away from the trunk and below the soil surface. Remember to move trees carefully. Roll the root ball on its side and “steer” it into the hole with the trunk. Straighten the tree upright in the hole, checking it from different angles to be sure it is fully upright.

Completing the Planting

For both container-grown and balled and burlapped plant material, backfill the planting hole with soil your mix and pack firmly. Make a rim of soil around the plant to act as a “saucer” for holding water.

Water thoroughly with a slow soaking, and use a root stimulator fertilizer to provide good initial stimulus for the roots to spread out.

Apply a 2-inch layer of mulch around your new planting, keeping an open space of 3 inches around the trunk or base of the plant to allow for air circulation.

Staking Container & Field Grown Trees and Shrubs

When larger trees or shrubs are planted, they are not yet firmly established in their new locations and may tip or lean as the soil settles. For larger trees, use three wires secured to anchor stakes in firm ground (never into the root ball). Where the wires touch the tree, they should be covered with rubber hose to prevent damage. Remove stakes as soon as roots become established. This can be as soon as a few months, so check your tree frequently. Stakes should not be left in place any longer than one growing season.

New Plant Care

All newly planted trees and shrubs need gentle care as they settle in to their new locations. To keep them healthy and encourage good initial growth…

Water Properly
Plants should be slowly soaked to a depth of 4 inches, which is the equivalent of about an inch of water per week. This is necessary during the first year or two. Let the hose run slowly at the base of the plant until the water has penetrated to the root depth. Too much water can also be a problem. Feel the soil. If it is soggy or squishy, do not add water. Frequent light watering is not as good as a thorough soaking once per week, which will encourage strong root growth.

Fertilize Appropriately
Your new plants should be given a Root Stimulator type fertilizer right after planting. You should not use a fertilizer meant for mature plants on new material, as it could cause damage to your plant. It is essential for new plants to develop a healthy root system – top growth will follow. After the first season, regular fertilizers can be used.

Prune Safely
Pruning at planting time may be necessary for larger trees to reduce leaf surface to match cut roots. Remove one-third of smaller twigs. Do not cut back the main trunk or larger branches. If shaping is necessary, trim side branches enough to get uniformity.

Be Alert for Insects and Diseases
Keep an eye out for holes or brown leaves or needles. This could be a sign of insect or disease problems. Ask our staff for help identifying the insect or disease and to prescribe appropriate treatments.

Special Care Plants
Some plants need extra special care because of their finicky needs. For example, azaleas, hollies, rhododendrons and dogwoods all need well-drained, acidic soils, high in organic matter and a shady location. Research the trees and shrubs you are planting to be sure you are meeting their needs right from the beginning.

It can seem intimidating to plant your own trees and shrubs, since they are an investment in your landscape that you hope to enjoy for many years. By understanding planting basics, however, you can easily give every plant a great start in its new home.

Time to Plant

Jump Start Your Pond

Are you ready to get your pond started up for another beautiful spring and summer? It can be a big job to rejuvenate such a large water feature so it remains balanced and healthy after a long, harsh winter, but with a few careful steps, your pond can be back in shape in no time.

When to Reopen Your Pond

It is important that you don’t try to get your pond started too early in the season. All risk of hard freezes should be long past, and even nightly frosts should be tapering off or already finished before you restart your pond. The exact time will vary based on your pond’s size, depth and location, as well as your ambient weather conditions and the pond’s overall ecology. For example, a smaller, shallower pond in a sunny area will be warmed up and ready to restart before a larger, deeper pond in a shady spot. It can be helpful to keep a journal or calendar from year to year to note when you reopened your pond and how successful your efforts were. In time, you’ll be able to adjust your calendar easily without risking the health and wellness of your pond, even if annual conditions change.

Easy Steps to Restart Your Pond

When you are ready to jump start your pond…

Remove the netting that was set in place last fall. If needed, clean and make repairs to the netting right away so it will be ready to use next fall. Store it safely where it will be easy to reach when needed again.
Remove excess sediment from the bottom of the pond with a vacuum or a net. It is not necessary to remove every bit of sediment, but most of the debris should be removed so the pump can function effectively.
Test last year’s pump and replace if necessary. Be sure to test any additional moving or electrical features, such as waterfalls, fountains or lighting around the pond so repairs can be made if needed.
If water level is low, add fresh water to desired height. Avoid overfilling the pond, however, which can disrupt the essential chemical and microbial balance that keeps the pond healthy.
Add de-chlorinator as necessary to remove heavy chemicals from the water that has been freshly added to the pond. As with any chemical treatments, be sure to test the water several times to be sure you reach the proper balance.
Place aquatic plants in the pond and begin fertilizing to meet their nutritional needs. These may be plants that you’ve overwintered in a safe location, or you may choose to add new or exotic plants in late spring.
Begin feeding fish when water temperature stays above 55 degrees. Keep feedings minimal at first as fish come out of dormancy, as excess food will only rot and lead to greater bacteria and algae growth in the water.

It is perfectly natural for your pond water to turn green at first, but with the proper plants it should balance itself out in no time. It may take a few days or even a couple of weeks for your pond to return to its healthy, active state, but if you’re restarted it properly, you shouldn’t have any major problems.
