When to fertilize trees and shrubs?
The best time to fertilize trees and shrubs is during their active growth periods, which are generally in the early spring and late fall. For deciduous trees, aim for late winter to early spring before new leaves appear, while evergreen trees and shrubs benefit from a fall feeding when the soil temperature is still above 60°F.
How to fertilize large trees?
Fertilizing large trees requires a specialized approach for effective nutrient distribution. The most recommended method is deep-root fertilization, where a nutrient solution is injected into the soil at a depth of 6 to 12 inches using a soil injection probe. This should be done in a grid-like pattern under the canopy and extending to the drip line of the tree.
Should I fertilize trees and shrubs in the fall?
Fertilizing trees and shrubs in the fall can be beneficial, especially for promoting root growth and overall health. Late fall, after the first hard frost but before the ground freezes, is an ideal time because the plants are entering dormancy and can store nutrients for a strong start in the spring. Opt for a slow-release, balanced fertilizer with an appropriate NPK ratio to nourish your specific types of trees and shrubs.
What is the best fertilizer for struggling trees?
For struggling trees, a balanced, slow-release fertilizer with essential micronutrients can make a significant difference. Look for a product with a balanced NPK ratio that also includes vital micronutrients like iron and zinc to promote overall health and vitality. Fertilizers specifically labeled for "stress recovery" or "root development" are ideal choices to rejuvenate weak or damaged trees.
Can you over fertilize shrubs and trees?
Yes, over-fertilizing trees and shrubs can lead to a range of problems, from nutrient imbalances to root burn. Excessive fertilization may cause rapid, lush growth that leaves plants more susceptible to diseases and pests. It can also lead to a build-up of salts in the soil, harming the plant's root system and affecting water absorption.
