Fall Fertilization and Pest Management: Why It Matters

September 25, 2024

As the leaves change and temperatures drop, many homeowners overlook an essential part of lawn and garden care: fall fertilization and pest management. Here’s why this seasonal maintenance is crucial for the health and vitality of your plants.

1. Strengthens Root Systems

Fall is the perfect time for fertilization because it encourages strong root development. A well-nourished root system helps plants store energy for the winter, leading to more vigorous growth come spring. Applying a microbial based fertilizer in the fall provides nutrients that support roots while minimizing growth above ground, which is ideal as plants prepare for dormancy.

2. Prepares for Winter

Fertilizing in the fall helps plants prepare for the harsh winter months. Nutrients like potassium enhance cold tolerance, making your plants more resilient against freezing temperatures. This preparation reduces the risk of winter damage and ensures a healthier start when the growing season returns. Consult with an Urban Forest Expert to see what your trees need to thrive.

3. Reduces Pest Populations

Fall is also a critical time for managing pests and diseases. Many insects, like grubs and aphids, are active in the cooler months and can cause significant damage if left unchecked. Applying insecticides or using natural pest control methods can help reduce their populations before they settle in for winter. Additionally, several lay eggs and overwinter during these months. It is a crucial time to get a pest population under control through eradicating eggs, overwintered or dormant insects, and more.

4. Disease Prevention

Certain diseases thrive in the fall, particularly fungal infections. By applying appropriate materials, you can protect your plants from these threats. Healthy plants with strong root systems are also less susceptible to disease, creating a double defense against potential outbreaks.

5. Improves Soil Health

Fall fertilization often involves adding organic matter, such as compost or liquid solutions, which enriches the soil. Healthy soil promotes beneficial microorganisms that enhance nutrient availability, improve drainage, and support overall plant health. This sets the stage for a thriving landscape in the spring.

6. Saves Time and Money

Investing in fall fertilization and pest control can save you time and money in the long run. Healthier plants are less likely to require extensive care and treatments in the spring, and preventing pest infestations can save costly damage repairs.

Conclusion

Fall is more than just a season of beautiful foliage; it’s a crucial time for preparing your garden and lawn for the future. By prioritizing fertilization and pest management now, you can ensure a vibrant and healthy landscape that thrives in the spring. Don’t wait—take action this fall to set your plants up for success!

Pest Notes: Vol. 4 – Palm Trees

July 2, 2025
Palms are most closely associated with grass. They are “monocots.”  Woody trees are “dicots.” Monocots have one point of growth, while dicots have two. With their second growing point (cambium), dicots can compartmentalize decay, regenerate woody tissue, respond to attack, etc. Palms, or monocots, do not have that capability. They have a single point of growth called the “meristem” also commonly called “spear-growth.” This is the main growing point of a palm – the center of its head. They do not expand radially, or get “thicker.”

Pest Notes: Vol. 3 - Cupressus sempervirens - Italian cypress

June 17, 2025
Italian cypress reminds me of the Queen of Hearts and her castle in Alice in Wonderland. They line the property boundaries of fine estates, work as an excellent screen species and require minimal maintenance. With their upright, erect structure, pruning is typically only needed to maintain a uniform shape when a branch over-elongates. Watering once established is minimal – a couple of deep watering events in the summer and you are good to go. It is, however, common for this species to develop secondary pests when improperly installed and maintained.  Planting depth and water is crucial – this species can contract root rot, which commonly occurs when planting depth is too deep and watering cycles too frequent and shallow. They can also deal with a canker that produces toxins, wreaking havoc on mineral-and-water conducting tissue.
