Gardeners in the mid-Atlantic region face specific challenges when it comes to plant diseases. Understanding these regional disease concerns is crucial for maintaining a healthy garden.
When disease takes hold in your garden, you will want to address it, of course. But, you will certainly want to rid your garden of any disease as part of your fall cleanup. Disease left to winter over will penetrate the soil where it will be sure to rear it’s ugly head during the next growing season. The best plan is to remove and burn or dispose of diseased flowers, foliage and stems.
Prevalent Diseases in the Mid-Atlantic
While specific disease challenges can vary, there are several prevalent plant diseases in the mid-Atlantic region that gardeners commonly contend with. It’s essential to be aware of these diseases to take proactive measures in preventing and managing them. Here are some notable ones:
- Powdery Mildew: This fungal disease is widespread and affects a variety of plants. It appears as a white powdery substance on leaves, inhibiting photosynthesis and weakening the plant.
- Late Blight: Known for affecting tomatoes and potatoes, late blight is a destructive disease favored by cool, wet conditions. It manifests as dark lesions on leaves and can lead to rapid plant deterioration.
- Anthracnose: Common on deciduous trees and shrubs, anthracnose is caused by various fungi. It results in dark lesions on leaves, causing defoliation and affecting overall plant health.
- Rust Diseases: Different rust fungi affect various plants, including roses and hollyhocks. Rust diseases cause orange or reddish-brown pustules on leaves, leading to leaf yellowing and premature leaf drop.
- Verticillium Wilt: This soil-borne fungus affects a broad range of plants, including tomatoes, strawberries, and trees. It causes wilting, yellowing, and, in severe cases, death of the plant.
- Downy Mildew: Common on plants like cucumbers and impatiens, downy mildew thrives in cool, moist conditions. It manifests as yellow patches on leaves with a characteristic downy growth on the undersides.
- Cedar-Apple Rust: Affects apple and crabapple trees, cedar-apple rust causes orange, gelatinous spore-producing structures on leaves. It requires both apple and cedar trees to complete its life cycle.
- Phytophthora Root Rot: This soil-borne pathogen can affect a variety of plants, causing root rot and decline in plant health. It is favored by poorly drained soils.
- Botrytis Blight (Gray Mold): Affects a wide range of plants, particularly those in humid conditions. It causes a gray, fuzzy mold on infected plant parts, leading to wilting and decay.
- Fire Blight: A bacterial disease affecting members of the rose family, such as apple and pear trees. It causes wilting, blackening, and a scorched appearance on branches.
It’s crucial for gardeners in the mid-Atlantic region to be vigilant in monitoring their plants, practice good sanitation, and, when necessary, use disease-resistant plant varieties. Additionally, adjusting cultural practices based on weather conditions can help mitigate the impact of these prevalent diseases.
Keeping a garden journal is a helpful solution to staying on top of disease. When you see that year after year, the August heat and humidity brings powdery mildew to your zinnias and tomatoes, you will know to be prepared for it.
Common Solutions for Disease Management
Managing and preventing plant diseases in the mid-Atlantic region involves a combination of cultural, biological, and chemical approaches. Here are some common solutions for the prevalent diseases mentioned:

Pruning and Trimming for the Mid-Atlantic
While doing your fall cleanup in the garden, it can be a good time to prune. Whether dealing with native species or introduced varieties, the focus of pruning is on promoting optimal growth and health. From combating invasive species to managing plant diseases through pruning, this segment addresses the unique issues that mid-Atlantic gardeners may encounter.
The secret to successful fall pruning is to give the plant enough time to heal over the cut areas. After pruning a plant must heal every cut. If you don’t think there is enough time before the first frost, then it’s best to save the pruning until the late winter or early spring.
You are pruning away disease. That is a must before winter, so that the disease doesn’t contaminate the soil overwinter.
General Pruning Tips
While this isn’t a tutorial on pruning, there are some general pruning tips that are handy to know:
- Minor pruning that is corrective, like pruning dead or diseased stems or branches, can and should be done anytime.
- Don’t prune plants that are grown for fruit or ornamental flowers until after the fruit drops.
- If you want as much growth as possible, don’t prune during or right after the first spring growth spurt. Prune before that happens.
- Prune plants that are damaged by wind or storms right away, any season.
- Aside from damage, trees and shrubs should not be pruned right before winter. The open wounds don’t have enough time to heal before the freeze.
- Stressed plants, bushes or trees should not be pruned, or as little as possible. The foliage is part of a plant’s healing and recovery.
- Pruning tools are best if they are kept sharp and clean.
Tips for Pruning Ornamental Plants
Pruning doesn’t stop plant growth. On the contrary, pruning stimulates plant growth. That’s why most gardeners do their pruning in the late winter or early spring, right before the plant is ready to come out of dormancy. Some pruning, however, is helpful in the fall.
- Removing all dead, diseased, or damaged branches and stems will help the plant overwinter. It will prevent disease and damaging insects from entering the plant.
- Shaping the plant may also be necessary in the fall. Removing crossing branches, or branches that rub against other branches can be done in the fall or the spring.
- Thinning may be necessary to let light into the center of the plant or bush, or to promote air circulation.
- Fall is a good time to prune back overgrown shrubs.
- Water sprouts and suckers should be pruned whenever they appear, whatever season it is.
- You may also want to remove old foliage from flowering plants. With some bushes, production of seed pods drains the energy of the plant.
- If a plant is reverting to a previous wild type, or a variegated plant is sending out plain shoots, those can be pruned in fall. This will help ensure that the new shoots in spring don’t follow this pattern.
- Declining plants can be reinvigorated with a vigorous pruning in fall or in early spring.
- Flowers that are produced on new wood are candidates for a fall pruning.
- Flowers that are produced on the previous season’s wood require a careful assessment. Make sure if you prune, that you are pruning last year’s wood.
9 Perennials to Cut Back in the Fall
- Hosta: Cutting back in the fall minimizes slugs that lay their eggs in the Hosta leaves in autumn.
- Columbine: Cutting back prevents leaf miners from overwintering.
- Yarrow: Yarrow is a dynamic accumulator. It is a great plant to “chop and drop” to build your soil any time of the year. If you cut it back in the fall, be sure to leave the new basal leaves that will be next year’s growth. Added bonus: the spent flower heads make lovely dried flowers.
- Bee Balm: Bee Balm is a vigorous grower. (that’s why we love it!) If you don’t want it to spread further, it helps to cut the seed heads off in the fall. Bee Balm can tend to suffer from powdery mildew in our humid summers, so pruning back the diseased portions in the fall and disposing of them is wise.
- Phlox: Another plant the often gets powdery mildew. Cut the stems about three inches above the soil line. (creeping phlox is not particularly prone to powdery mildew)
- Peonies: cutting back in the fall will reduce the chances of powdery mildew and other issues like botrytis. Pruning back to three inches above the soil line will make it easier to spread mulch as well.
- Daylilies: If you are planning to divide daylilies, which is a good idea every few years, cutting them back to about four to six inches will make that easier in the spring.
- True Lilies: Cutting spent foliage in the fall minimizes disease. Wait until after the first frost, so that they have as much time as possible to store energy in their bulbs.
- Bearded Iris: Pruning irises back in fall can reduce the chances that iris borers will overwinter in your garden. Like bulbs, it is best to wait until after the first frost so the rhizomes store the maximum amount of energy for the next growing season.
Weeding is an essential aspect of garden maintenance. Gardeners have learned that some weeds need constant vigilance, and if left to overwinter, will be harder to battle in the spring. Some weeds, however, might be more of an ally if left to overwinter.
If you weed your garden in the fall, consider covering the soil with organic material. Bare soil is not your garden’s friend, no matter what season. You can use compost, wood chips, straw or any type of mulch that will protect the soil from runoff or from being blown away by fall or winter winds.
Identifying Common Weeds in the Mid-Atlantic
There are some common weeds that plague mid-Atlantic gardens. Understanding the enemy is the first step toward effective weed control.
Here are some common weeds in the mid-Atlantic garden:
- Common Chickweed (Stellaria media): This low-growing weed has small, white flowers and thrives in cool, moist conditions. It can quickly spread and become a nuisance in lawns and garden beds.
- Crabgrass (Digitaria spp.): Crabgrass is an annual grass weed that is notorious for invading lawns and garden areas. It spreads rapidly, particularly in bare or disturbed soil.
- Dandelion (Taraxacum officinale): Recognized by its distinctive yellow flowers and puffball seed heads, dandelion is a perennial weed that can be found in lawns, gardens, and disturbed areas.
- Broadleaf Plantain (Plantago major): This broadleaf weed is recognizable by its rosette of leaves and tall seed spikes. It thrives in compacted soils and disturbed areas.
- Common Purslane (Portulaca oleracea): Purslane is a succulent weed with fleshy leaves and stems. It can be found in garden beds, lawns, and other cultivated areas.
- Japanese Knotweed (Fallopia japonica): A highly invasive weed, Japanese knotweed can quickly spread and is challenging to eradicate. It has bamboo-like stems and heart-shaped leaves.
- Ground Ivy (Glechoma hederacea): Also known as creeping Charlie, ground ivy is a low-growing perennial weed with round, scalloped leaves. It often invades lawns and garden edges.
- Yellow Nutsedge (Cyperus esculentus): Yellow nutsedge is a perennial grass-like weed with triangular stems. It’s often found in wet or poorly drained soils.
- Bittercress (Cardamine hirsuta): Bittercress is a winter annual weed with small white flowers. It tends to appear in early spring and can spread rapidly.
- Wild Violet (Viola sororia): Recognized by heart-shaped leaves and purple flowers, wild violets are perennial weeds that can be challenging to control in lawns and garden beds.
- Hairy Bittercress (Cardamine hirsuta): This winter annual weed produces small white flowers and can quickly spread in garden beds, especially in early spring.
To effectively manage these weeds, it’s essential to employ a combination of strategies, including proper lawn and garden maintenance, mulching, hand weeding, and, if necessary, targeted organic herbicide use. (see my vinegar recipe) Regular monitoring and early intervention can be the key to preventing an overwhelming weed infestation in the spring.
Cleanup Tools for Mid-Atlantic Gardeners
Having the right tools is very helpful for efficient fall cleanup in the garden. Not every tool you see on the popular gardening websites or on Amazon is necessary, to be sure. But a few well-designed tools can make the process more efficient. Here are some of the most useful tools:

By following these cleaning and storing practices, you’ll extend the life of your garden tools and make your gardening tasks more enjoyable and efficient.
Leaving Habitat for Wildlife
While many gardeners may have been conditioned to clear everything away in the garden in preparation for winter, there are several reasons to question that training. Leaving certain plants in the garden instead of cleaning them up and clearing them away for winter serves several important ecological and garden health purposes. Here are some reasons why it’s beneficial to leave certain plants standing during the winter:
- Wildlife Habitat: Many plants, even in their dried or dormant state, provide crucial habitat and food sources for wildlife during the winter months. Seed heads, dried flowers, and standing stems offer shelter for insects and small animals. Birds, in particular, may feed on seeds and insects, contributing to the biodiversity of your garden.
- Overwintering Insects: Some beneficial insects, such as ladybugs and butterflies, overwinter in various stages on plant material. Leaving the plants undisturbed provides a safe haven for these insects, aiding in natural pest control when the growing season begins again in spring.
- Natural Mulch and Erosion Control: Standing plants can act as natural mulch, helping to protect the soil from erosion caused by winter weather conditions. The plant material can provide a protective layer over the soil, preventing it from being washed away by rain or snow.
- Winter Interest: Dried seed heads, interesting plant structures, and textures can add visual interest to the winter garden. These elements create a different but equally captivating aspect of your garden, showcasing its beauty even in the quieter, colder months.
- Nutrient Cycling: As plants decompose over the winter, they contribute organic matter to the soil. This process enhances soil structure, promotes microbial activity, and adds nutrients, preparing the garden for the next growing season.
- Disease Prevention: Clearing away all plant material can sometimes disturb the natural balance in the garden and expose soil to potential erosion. Additionally, leaving some plant material in place can act as a barrier, preventing soilborne diseases from splashing onto healthy plants.
- Time and Energy Conservation: Allowing certain plants to stand over the winter means less work for you in terms of cleanup. It conserves your time and energy, especially for perennials and grasses that can be trimmed back in the spring.
When deciding which plants to leave in the garden for winter, consider factors such as the plant’s structural integrity, wildlife value, and potential for disease. Incorporating a mix of both cleaned-up areas and those left more natural can strike a balance between garden aesthetics and ecological benefits.
Winter Preparation Tips
Understanding Mid-Atlantic Winter Weather
The mid-Atlantic region experiences a varied winter climate, characterized by fluctuating temperatures, occasional freezes, and periods of thaw. Addressing these weather dynamics is essential when choosing the right mulch for your garden.

- Structural Support for Snow Accumulation: Brushing off Snow: For plants susceptible to damage from heavy snow accumulation, gently brush off excess snow to prevent branches from bending or breaking.
- Wrapping Delicate Plants: Protecting Fragile Species: Delicate or marginally hardy plants may benefit from burlap wrapping to shield them from harsh winter conditions.
- Monitoring for Pests and Diseases: Vigilance in Winter: Keep an eye out for signs of pests and diseases, which may still be active during mild periods. Early detection allows for prompt intervention.
Mid-Atlantic Mulching Considerations
Mulch serves as a protective layer, insulating plants from extreme temperature shifts and reducing the risk of frost heaving. Proper mulching is a key aspect of preparing your garden for the colder months, providing protection to plants and supporting soil health.
Choosing the Right Mulch:
- Organic Mulches: Materials like shredded leaves, straw, wood chops or bark contribute organic matter to the soil as they decompose, enhancing its fertility. These materials also help regulate soil temperature and moisture.
- Pine Straw: Particularly popular in the mid-Atlantic, pine straw provides excellent insulation and is resistant to compaction. It’s especially beneficial for acid-loving plants.
- Evergreen Boughs: Recycling branches from evergreen plants can create a protective cover. These boughs not only insulate but also provide shelter for wildlife.
- Depth and Coverage: Apply mulch with a thickness of 2 to 4 inches, ensuring even coverage. This depth provides insulation without suffocating plant roots.
- Avoid Piling Mulch Against Stems: Pull mulch away from the base of plants to prevent trapping excess moisture and discourage pests or diseases.
- Extend Mulch Beyond the Drip Line: Extend mulch slightly beyond the drip line of trees and shrubs, covering the root zone effectively.
Timing of Mulching:
- Late Fall Application: Mulch applied in late fall after the ground has cooled helps regulate soil temperature during freeze-thaw cycles.
- Early Spring Inspection: In early spring, assess the condition of mulch and replenish if necessary. This helps retain soil moisture as temperatures rise.
Consideration for Perennials:
- Leave Some Stems Standing: For perennials, consider leaving some stems standing through winter. These can provide structure and catch snow, adding an extra layer of insulation.
By carefully considering the winter weather patterns specific to the mid-Atlantic region and adopting these mulching practices, you can fortify your garden against the challenges of the season, ensuring its resilience and vitality come spring.
Soil Care in the Mid-Atlantic
Maintaining healthy soil is the foundation for a successful garden. Although we don’t often think about it during the winter, soil-building is something that happens all year long.
Recommendations for Mid-Atlantic Cover Crops
Planting cover crops in the fall is a great way to build soil for the next growing season. By planting cover crops suited to the region, gardeners can enhance soil fertility and structure over the winter.
Here are some cover crops that work well in the mid-Atlantic region over the fall and winter months:
Winter Rye (Secale cereale):
- Benefits: Excellent for erosion control and weed suppression. It establishes quickly in the fall and provides good ground cover.
- Considerations: It may become difficult to terminate in the spring, so proper management is essential.
Crimson Clover (Trifolium incarnatum):
- Benefits: Fixes nitrogen, improves soil structure, and attracts beneficial insects. It has vibrant red flowers that add aesthetic appeal.
- Considerations: Sensitive to cold temperatures, so it’s best suited for fall planting.
Hairy Vetch (Vicia villosa):
- Benefits: Fixes nitrogen, adds organic matter, and suppresses weeds. It has a sprawling growth habit.
- Considerations: Can become invasive if not properly managed. It may be more suitable for well-drained soils.
Winter Wheat (Triticum aestivum):
- Benefits: Erosion control, weed suppression, and contributes organic matter to the soil. It establishes quickly in the fall.
- Considerations: Like winter rye, it may be challenging to terminate in the spring if allowed to grow too long.
Austrian Winter Pea (Pisum sativum subsp. arvense):
- Benefits: Fixes nitrogen, improves soil structure, and provides forage for livestock. It has a vining growth habit.
- Considerations: May not survive harsh winter conditions, so it’s often used in more temperate areas of the mid-Atlantic.
Field Radish (Raphanus sativus):
- Benefits: Deep taproot helps break up compacted soil, scavenges nutrients, and suppresses weeds. Adds organic matter when it decomposes.
- Considerations: Cold-tolerant but may winterkill in extremely harsh conditions.
Oats (Avena sativa):
- Benefits: Quick establishment, good for erosion control, and adds organic matter to the soil. It’s often used in mixtures with other cover crops.
- Considerations: May winterkill in colder regions, making termination easier in the spring.
Winter Barley (Hordeum vulgare):
- Benefits: Similar to winter wheat, offering erosion control and weed suppression. It’s well-suited for fall planting.
- Considerations: Like other cereal grains, it may be challenging to terminate if allowed to grow too long in the spring.
When choosing cover crops, consider your specific goals, the characteristics of your soil, and the climate in your area. Additionally, using cover crop mixtures can provide a range of benefits and enhance biodiversity in the soil. Rotate cover crops annually to maximize their effectiveness and contribute to long-term soil health.
Adding Organic Material over Fall and Winter
If you don’t plant a cover crop in the fall, add organic matter into and on top of your garden beds. You can use compost or shredded leaves to improve the soil and minimize the risk of soil erosion or nutrient run-off. Here are several other methods of enriching the soil:
- Composting: Continue composting kitchen scraps and garden waste throughout the winter. While the decomposition process may slow down in colder temperatures, composting still occurs, and you can enrich your compost pile with occasional turnings.
- Manure Application: Apply well-aged manure to your garden beds. Manure contributes organic matter and essential nutrients to the soil. Ensure that the manure is fully composted to avoid nitrogen imbalances and potential contamination.
- Green Manure or “Chop-and-Drop”: Instead of planting cover crops, consider using green manure by growing nitrogen-fixing plants like legumes and then chopping them down to add organic matter to the soil. This is known as “chop-and-drop” and can be done with various plant materials.
- Mineral Amendments: Apply mineral amendments such as rock dust or agricultural lime to improve soil structure and nutrient availability. These amendments provide essential minerals that may be lacking in the soil.
- Worm Composting (Vermicomposting): If you have a worm composting system (vermicompost), continue feeding your worms kitchen scraps throughout the winter. Worm castings are nutrient-rich and enhance soil fertility. You will want to move them inside a garage or basement to keep them from freezing.
- Biochar Application: Apply biochar to the soil. Biochar is a stable form of carbon that helps improve soil structure, water retention, and nutrient availability. It also enhances microbial activity.
- Collecting Coffee Grounds: If available, collect used coffee grounds and incorporate them into the soil. Coffee grounds are a good source of organic matter and add nitrogen to the soil.
- Winter Composting Bins: Use a winter composting bin to continue composting during colder months. These bins are designed to maintain temperatures suitable for decomposition even in winter.
Remember to tailor these practices to your specific climate, soil type, and gardening goals. A combination of these methods can contribute to a holistic approach to soil improvement over the winter.
Mid-Atlantic Winter Watering Guidelines
As winter settles in the mid-Atlantic region, a common misconception is that plants require less water during the colder months. However, proper winter watering is essential to ensure the health and vitality of your garden. In this section, we address the misconception about reduced watering in winter and provide guidance on maintaining adequate hydration for your plants.
Addressing the Misconception
The Winter Hydration Myth:
Contrary to popular belief, plants still need water during winter, albeit in smaller quantities than during the growing season. While some plants may enter a dormancy period, their roots are still active and continue to absorb moisture from the soil. Additionally, winter winds and sun exposure can lead to soils drying out, making supplemental watering important, especially during dry spells.
Proper Winter Watering Practices
Hydration in Dry Spells:
- Monitor Soil Moisture: Regularly check the moisture level in the soil, especially during dry spells or when snow cover is insufficient. Stick your finger into the soil, and if it feels dry several inches below the surface, it’s time to water.
- Choose the Right Time: Watering in the morning allows the soil to absorb moisture before temperatures drop at night. Avoid watering in the evening to prevent the formation of ice on the soil surface.
- Watering Frequency: Adjust the frequency of watering based on weather conditions. If the winter is dry with little precipitation, increase the frequency of watering to compensate for the lack of natural moisture.
- Avoid Waterlogged Soil: While ensuring adequate hydration is crucial, it’s equally important to avoid waterlogged soil. Excess moisture can lead to root rot and other issues. Adjust the amount of water based on the specific needs of your plants and the soil’s drainage capacity.
- Protect Evergreens: Evergreen plants are more susceptible to winter dryness. Provide a deep watering before the ground freezes to help them withstand winter winds and retain moisture.
- Mulching for Moisture Retention: Apply a layer of mulch around the base of plants to help retain soil moisture. Mulch acts as an insulating layer, protecting the soil from temperature fluctuations and reducing evaporation.
By dispelling the myths about watering in winter and adopting proper winter watering practices, you can support the resilience of your plants, ensuring they enter spring healthy and ready for the growing season ahead.
