At Cutting Edge Tree Professionals (CETP), we want to help you get the best results for your spring planting. By understanding common pests and diseases and taking proactive steps to manage them, you can ensure a thriving garden and a healthy landscape.

In this blog post, we’ll cover four of the most common pests and diseases that may affect your spring plantings. In this blog post, we’ll cover four common pests and diseases in Pennsylvania that may affect your spring planting including: deer, powdery mildew, aphids and root rot. Read on to learn how to identify, prevent, and treat these common garden concerns and issues.

1. Deer: A Major Threat to Spring Planting

Deer can be a significant problem for gardeners, especially in suburban and rural areas. While deer are beautiful animals to watch, they can cause serious damage to your plants. They’re known to feed on a variety of vegetation, including flowers, shrubs, and even young trees. During the spring, deer are especially attracted to newly sprouted plants.

How to identify deer damage:

Deer tend to eat plants at a height of 3 to 5 feet.
You may notice clean, jagged edges where the deer have nibbled on leaves, flowers, or branches.
Deer also leave behind tracks in soft soil or bedding areas in your garden.

Prevention and management:

Fencing: Installing a tall fence (at least 8 feet) can be an effective deterrent. Deer are unlikely to jump over a fence of this height.
Repellents: Commercial deer repellents are available, but you can also make your own using natural ingredients like garlic or hot pepper. Apply these repellents regularly, especially after rain.
Deer-resistant plants: Consider planting species that are less attractive to deer, such as lavender, daffodils, or marigolds.
Motion-sensor devices: Some gardeners have found success using motion-activated sprinklers or lights to scare deer away.

2. Powdery Mildew: A Common Fungal Disease

Powdery mildew is a fungal disease that affects many plants, particularly during the humid and warm conditions of spring. It’s commonly seen on a variety of trees, shrubs, and flowers, and while it’s not always deadly, it can weaken plants over time if left untreated.

How to identify powdery mildew:

Powdery mildew appears as white or grayish powder on the tops and undersides of leaves, stems, and buds.
In severe cases, the affected plant’s leaves may become distorted or yellow.
Powdery mildew thrives in warm, dry environments, making it more common in the spring when the weather is unpredictable.

Prevention and management:

Space plants properly: Ensure adequate air circulation between plants to help reduce humidity, which fosters the growth of powdery mildew.
Water properly: Avoid overhead watering, which can create moist conditions favorable for mildew. Instead, water plants at the base.
Prune affected areas: If you notice early signs of powdery mildew, prune off infected leaves or branches and discard them away from the garden to prevent further spread.
Fungicides: There are several fungicides available that are effective at preventing or treating powdery mildew. Look for products containing sulfur, neem oil, or potassium bicarbonate, and always follow the instructions for application.

3. Aphids: Tiny But Destructive

Aphids are small, sap-sucking insects that can cause significant damage to your plants. They feed on the leaves, stems, and flowers of a wide variety of plants, including vegetables, trees, and ornamental shrubs. While they may seem harmless at first due to their size, aphids can transmit plant diseases and cause plants to become deformed or weakened.

How to identify aphids:

Aphids are usually small, green, yellow, or black, and often appear in clusters on the undersides of leaves.
You may notice a sticky substance on leaves (called honeydew) that aphids secrete, which can attract ants and encourage the growth of mold.
Aphids cause plants to curl, yellow, or become stunted, as they drain the sap from the plant.

Prevention and management:

Natural predators: Encourage natural aphid predators like ladybugs, lacewings, and predatory beetles, which will help control aphid populations.
Insecticidal soap: A simple solution to aphid infestations is using insecticidal soap, which is safe for plants and effective at killing aphids.
Water jets: A strong spray of water from a hose can knock aphids off plants, reducing their numbers.

4. Root Rot: A Silent Killer

Root rot is a common problem for many garden plants, especially those that are overwatered or planted in poorly-drained soil. This disease is caused by various fungi that attack the plant’s roots, causing them to decay and die. Root rot weakens the structure of a tree, which can make it dangerous to property and people as it can be susceptible to falling over. Once the roots are infected, the plant is unable to absorb water and nutrients, which can lead to its eventual death.

How to identify root rot:

Yellowing or wilting leaves, even though the plant is being watered regularly.
A musty or sour smell coming from the soil around the plant’s base.
Brown or blackened roots when you pull the plant from the ground.

Prevention and management:

Proper watering: Avoid overwatering your plants and ensure that your garden beds have good drainage.
Well-draining soil: Use a mixture of compost, sand, or perlite to improve soil drainage.
Remove affected plants: If root rot is present, it’s important to remove and discard the infected plants to prevent the fungus from spreading. Call your local arborist right away to assist. In the Centre County, Harrisburg, and Susquehanna Valley areas, Cutting Edge Tree Professionals can help you remove trees and plants experiencing root rot that can be dangerous.
