Organic Gardening Tip of the Week

Blackberries have three possible growth habits—erect, semi-erect or trailing. The way to train and prune them will depend on the type. If you did not top the new canes during the late summer, you should top them to about 5’ (or the height of your trellis or fence). Dormant pruning of erect blackberries entails removing dead canes (color is brown vs a newer green cane) and cutting back laterals to 12–18”. Semi-erect blackberries should be thinned to 5 to 8 of the strongest canes, shorten the laterals to 12–18” and remove any growing on the lower 3’ section of the main canes. Tie to a fence or trellis to provide support. Trailing blackberries are less cold tolerant and in cold regions the canes can be left on the ground and protected with rowcover or mulch over the winter. In spring the canes can be lifted and tied to a trellis at 3’ and 6’.

Fruit trees should be pruned from the time they are planted. Early pruning will shape the tree into a desirable structure and will encourage better fruit production and less broken branches later in life. There are three types of pruning systems, Central Leader, Vase or Open Center and Modified Central Leader. The type of tree will dictate the pruning system chosen. Central Leader is best for apples, pears, persimmons and pecans. Apples, pears, peaches and nectarines can be pruned during the winter, but wait until summer to prune apricots, cherries and pluots. Do not prune when rain is forecast–you want dry weather for the cuts to heal over. If your trees have started to bloom or buds are swelling, it is a good idea to wait until either next dormant season or until you are ready to do your summer pruning. Make sure your pruners are clean and sharp. Clean up leaves and dropped fruit on the ground to decrease potential overwintering spots for pests and disease.

Bare root trees and plants are a popular choice among gardeners and landscapers due to their affordability, ease of handling, and the promise of healthy, vibrant growth. However, when these plants arrive at your doorstep, it's crucial to know how to care for them, especially if you can't plant them in the ground right away. In this guide, we will walk you through the steps of heeling in your bare root trees or plants to ensure they thrive until you're ready to transplant them into their permanent homes.

Determining Optimal Planting Conditions

Your plant’s success hinges on selecting the right time for transplanting, and this decision depends largely on the air and soil temperatures in your region. When considering winter planting, it's essential to gauge whether the prevailing temperatures align with the needs of your plants.

In regions where winter temperatures consistently fall below freezing, it's typically impractical to plant bare root specimens directly into the ground. Instead, opt for heeling in as a temporary measure to shield your plants from frost damage until more favorable planting conditions arise in the spring. Ideal soil temperatures for planting bare root plants generally above 40°F (4°C), while air temperatures should be in the same range to support healthy root development and minimize the risk of frost damage.

Our customers have always enjoyed healthier plants when receiving them during winter dormancy, versus risks associated with shipments after temperatures have increased in shipping channels.  Shipping bare root plants during dormancy, before the risk of developing buds and leafing out, is a key strategy for ensuring their health. This approach minimizes stress and potential damage during transit, allowing plants to arrive in optimal condition for transplantation. It also provides gardeners with greater control over the timing of planting, leading to healthier, more vigorous growth when the plants are finally established in their new homes.

Step 1: Inspection and Assessment

The first order of business upon receiving your bare root trees or plants is to carefully inspect them. Look for any signs of damage, particularly at the graft site in the case of bare root trees. Minor issues like broken branches are generally not a cause for concern, as they can regrow once spring arrives. However, any severe damage or signs of disease should be documented and reported to the seller if necessary.

Step 2: Gathering Your Materials

Before proceeding with heeling in your bare root trees or plants, gather the necessary materials. You'll need a large pot, wheelbarrow, or some type of container, loose soil, compost, or wood shavings (avoid cedar, redwood, or rice hulls), and access to a suitable location for storage.

Step 3: Choosing the Storage Location

Your choice of storage location for heeling in your bare root trees or plants will depend on the weather conditions in your area. If the ground is not frozen and outdoor temperatures are reasonable, you can perform this process outdoors. However, if the weather is harsh or the ground is frozen, consider alternative storage options such as a garage, shed, basement, or greenhouse. The key is to maintain a temperature between 35-45°F to keep the trees/plants dormant until planting time.

Step 4: Preparing the Container

Whether you opt for a pot, wheelbarrow, or another container, ensure that it is clean and free from contaminants. A container with drainage holes is ideal to prevent waterlogging. Fill the container with loose soil, compost, or wood shavings. This medium will provide insulation and protection for the bare roots.

Step 5: Placing Your Bare Root Trees or Plants

Gently place your bare root trees or plants into the prepared container. Ensure that the roots are evenly spread out and do not overlap. The depth at which you plant them should mimic their natural growth position, with the roots fanning out and the crown or bud union (in the case of grafted trees) slightly above the soil level.

Step 6: Covering and Moistening

Once your trees or plants are securely positioned in the container, cover them with the chosen medium (soil, compost, or wood shavings). Make sure the roots are completely covered but avoid burying the crown or bud union too deeply. The medium should insulate the roots and protect them from drying out.

Step 7: Maintaining Moisture Levels

Proper moisture management is crucial during the heeling-in process. While you want to keep the roots moist, avoid overwatering and creating a waterlogged environment. Check the moisture level regularly, and water if the medium begins to dry out. Ensure that the container has proper drainage to prevent excess moisture buildup.

Step 8: Temperature Control

Maintaining the right temperature is vital for keeping your trees or plants dormant until you're ready to plant them. Aim to keep the storage area between 35-45°F. This temperature range ensures that your plants remain in a state of dormancy, preventing premature leafing out or blooming.

Step 9: Timing and Planting - Assessing Planting Readiness After Winter

Determining the right time to transplant your heeled-in bare root trees or plants after winter is critical for their successful establishment. Proper timing can help your plants thrive, while planting too early can expose them to various risks. Here's how you can gauge if the weather is conducive to planting and how to mitigate potential risks:

Assessing Planting Readiness:

1. Soil Temperature: The soil temperature is a crucial factor in determining planting readiness. Ideally, soil temperatures should consistently range above 40°F (4°C) for most bare root plants. You can measure soil temperature with a soil thermometer inserted a few inches deep into the ground.

2. Air Temperature: The air temperature should be in the same range as soil temperature to support healthy root development. Check local weather forecasts to monitor air temperatures and trends in your area.

3. Frost Risk: Keep an eye on the last expected frost date in your region, typically found in local gardening resources or online. Planting before this date can expose your plants to the risk of frost damage.

4. Soil Moisture: Ensure that the soil is not excessively wet or waterlogged. Planting in soggy conditions can lead to root rot and other issues.

Risks of Planting Too Early and Mitigation:

1. Frost Damage: Planting too early can expose your bare root plants to frost damage, which can harm tender new growth. To mitigate this risk, wait until the last expected frost date has passed or use frost protection measures such as row covers, cloths, or temporary greenhouses.

2. Slow Growth: Early planting in cold conditions can stunt plant growth and development. It's essential to wait until both soil and air temperatures are consistently within the recommended range to ensure vigorous growth.

3. Disease and Pest Vulnerability: Cold, wet soil can increase the vulnerability of your plants to soil-borne diseases and pests. Proper soil temperature and drainage are essential to minimize these risks.

4. Watering Challenges: In cold conditions, plants may not absorb water efficiently. Be cautious not to overwater during the early stages after planting. Water sparingly until the plants show signs of active growth.

5. Root Stress: Planting too early can stress the plant's roots, making them more susceptible to damage and disease. To minimize this risk, gently handle the roots during transplanting, and avoid planting in frozen or excessively wet soil.

The key to successful planting after winter lies in patience and careful observation of environmental conditions. Wait until both soil and air temperatures are suitable for your specific plants, and be mindful of potential risks associated with early planting. By taking these precautions and timing your transplanting correctly, you'll give your heeled-in bare root trees or plants the best chance to flourish in their new outdoor homes.

Additional Tips:

1. Protection from Wildlife: If your storage area is outdoors, consider protecting your heeled-in plants from wildlife by using fencing or barriers.

2. Labeling: To avoid confusion, label your heeled-in plants with their species or variety. This ensures you can easily identify them when it's time to plant.

3. Monitoring: Regularly check your heeled-in plants for any signs of stress, disease, or pests. Early detection can help you take prompt action.

4. Choosing Suitable Containers: The size of your container should accommodate the size of the bare root trees or plants you have. It should provide enough room for the roots to spread comfortably.

5. Pruning: If your bare root trees have excessively long or damaged roots, consider pruning them before heeling them in. This can encourage healthy root development.

The best place to store your firewood is outside, away from the house, instead of stacked right up against the house. Firewood that is stacked right up against the house can give insects an avenue to enter the house or hide out. Insects such as cockroaches, termites, carpenter ants, beetles or pill bugs can take up residence in the wood pile. It is also a good idea to not store firewood inside the home either. Any insects that are dormant in the wood can warm up enough to wake up and take up residence in your home. Stay warm this winter, but keep the bugs outside!

Winter is here to stay and for some it is a welcome break to working outdoors. Some may want to just stay indoors next to a warm fire and sip some cocoa! But don't stay indoors too long because there is still a lot of things you should be doing out in the garden and orchard during the winter. In the orchard, continue cleaning up dropped fruit, applying dormant oils or fungicides and prune your apples, pears, peaches or nectarines. Around your garden make sure you tuck in your perennial veggies (asparagus, artichokes, rhubarb…) with a thick layer of mulch and have some Agribon rowcover or Frostblankets on hand to protect your plants from frost damage. Watch our video or read our article for all of the things to do in your garden during December.

For growing garlic effectively, apply fertilizers during fall planting to ensure that nutrients reach the roots before cold winters set in. Use a garden fork to gently incorporate the fertilizer into the soil around the raised bed, avoiding direct contact with plant cloves or seed garlic to prevent potential harm.

This method supports robust growth in hardneck cloves and softneck garlic, helping to achieve a healthy garlic head and prevent issues like turn yellow in the garlic scapes or smaller cloves in the spring.

Summary

Garlic plants can withstand cold weather as long as they are not exposed to a sudden drop of freezing temperatures. To help protect garlic from sudden drops in temperatures, apply a thick layer of mulch such as straw mulch (seed-free); a minimum of 4 inches is recommended, and thicker in regions with harsh winters (up to 8 inches). In the spring the mulch can be pulled back to allow the soil to warm up faster and also helps avoid excess moisture, which can cause rot. Another benefit to mulching is weed control. Garlic does not like to compete with weeds and it will suffer if weeds are not removed. You should not be applying any nitrogen fertilizers over the winter as that will lead to an increase in top growth. After weeding and mulching, now you just have to wait until the spring. Once spring arrives and the soil starts to warm and snows melt, pull back the mulch and feed with an all purpose fertilizer, bone meal or another mix that is high in phosphorus.

In addition to good orchard sanitation (picking up rotten fruit and raking leaves), applying dormant sprays in the fall and winter is a great way to reduce overwintering pests & diseases in the home orchard. Dormant oils are applied when trees have dropped their leaves and are dormant. The oils can be applied when daytime temperatures are over 35-40°F. Dormant oils control aphids, scale, spider mites and many other insects by smothering eggs and larvae.

Peach leaf curl, also known as curly leaf, curly blight or leaf blister, has been recognized as a common disease since the early 1800s. It is caused by the fungus Taphrina deformans and can affect the blossoms, fruit, leaves and shoots of peaches and nectarines. Peach leaf curl is the most common disease found in backyard orchards and can weaken the tree over time if the disease is not controlled. Cool (48-68°F) wet weather when leaves are first opening favors the disease. Watch our video on Peach Leaf Curl where Tricia shows how to care for your trees.

To control diseases such as peach leaf curl, a fungicide is applied multiple times throughout the dormant season. An easy way to remember when to apply the fungicide is after leaf drop, New Years day (or around that time) and a final treatment on Valentine’s Day (before buds have broken or blossoming). For more information you can also read our blog Peach Leaf Curl Control.

Fall-planted flower bulbs such as tulips, daffodils, hyacinth, or crocus are wonderful additions to the landscape, but if you live in warmer winter climates (as in USDA zones 8 and above), these bulbs will need to be pre-chilled or vernalized before planting to successfully bloom. If you are in zones 4-7, your bulbs will receive enough natural chilling over the winter to bloom successfully and will only need to be dug up and divided every 3-4 years. Read the full article here.
