Trees are an essential part of our urban landscape, providing beauty, shade, and environmental benefits. As a homeowner in Calgary, understanding when and how to properly fertilize your trees can significantly impact their health and longevity. At Evergreen LTD, we're committed to providing you with expert advice and services that ensure your trees thrive throughout the seasons.
Optimal Timing for Tree Fertilization
Timing your tree fertilization correctly is crucial for maximizing nutrient uptake and ensuring healthy growth. The best time to fertilize trees is after they have fully expanded their leaves. This stage usually occurs in late spring or early summer. At this point, photosynthesis is at its peak, enabling the tree roots to absorb and transport nutrients effectively, which are then converted into sugars essential for growth and development.
The Misconceptions of Deep Root Fertilization
Deep root fertilization involves injecting fertilizer directly into the soil around the tree's root zone. While it might seem like an effective way to deliver nutrients directly to where the tree needs them the most, this method has significant drawbacks:
Limited Coverage:Â Deep root fertilization typically affects only a small area around the injection site, potentially missing large sections of the root system.
Root Damage:Â The high-pressure injection can damage sensitive root hairs, which are crucial for nutrient and water absorption.
Depth Issues:Â It's challenging to control the depth accurately, and nutrients may end up too deep where roots cannot access them effectively.
Advantages of Soil Drenching
An alternative to deep root fertilization is the soil drench method. This technique involves applying a liquid fertilizer over the soil surface around the tree, which then seeps into the ground to reach the roots. Soil drenching offers several benefits:
Extensive Reach:Â Covers a larger area, ensuring more roots can access the nutrients.
Gentle on Roots:Â Avoids physical damage to root hairs, maintaining the tree's ability to absorb water and nutrients.
Consistent Uptake:Â Ensures a steady supply of nutrients, especially important in established lawns where tree and grass roots compete for resources.
Seasonal Considerations
For optimal results, consider applying organic fertilizer twice a year—during spring and fall. These seasons are ideal because:
Spring Application:Â Supports vigorous growth and prepares the tree for the productive summer months.
Fall Application:Â Helps trees store nutrients and strengthen before the winter dormancy period.
Choosing the Right Fertilizer
Selecting the appropriate type of fertilizer is vital for the health of your trees. Organic fertilizers are highly recommended because they release nutrients slowly, reducing the risk of nutrient runoff and providing a continuous nutrient supply. These fertilizers also contribute to soil health by supporting microbial activity.
