how and when to fertilize evergreens

Evergreen trees and shrubs are generally easy to care for. But their constantly green appearance can lead to the belief that they don’t need fertilizer or other support from the grower. At the same time, autumn, that is, the period before the transition of evergreens to hibernation, is a good time to feed them. A sufficient amount of nutrients will help plants to endure the cold season without loss.

Signs that an evergreen plant needs to be fertilized

With proper nutrition, plants stay green longer and continue to grow year after year. If uncharacteristically slow crop growth is noticed, this may indicate a lack of fertilizer. Another sign is that the needles or leaves lose color, turn yellow or brown.

Heavily compacted soil, diseases and weeds, and cold or hot weather can also cause similar symptoms. But in the absence of obvious pests, moderate weather and well-plowed land, you should think about fertilizing. In addition, an evergreen plant needs a slow release feed if it has been transplanted from place to place, writes Homes and Gardens.

When and how to fertilize

Evergreens should be fertilized in three stages: early spring, summer and early autumn. Do not fertilize during the dry season. This can make it difficult for the plant to absorb water and kill the crop.

To prepare the plant for winter, fertilizers with a minimum nitrogen content should be used. At this time, phosphorus and potassium are important, which contribute to the formation of wood and help young shoots to withstand the winter. In spring and summer, you need to add more nitrogen and do not forget about phosphorus, potassium and magnesium.

In total, there are two main ways to fertilize evergreens. The most common is spreading the fertilizer over the top edge of the soil before watering, as if fertilizing a lawn. An alternative option involves fertilizing dug holes. They dig around the plant, but not close to the trunk. It is necessary to mentally outline a circle on the ground, projecting the crown of a tree onto it. In this circle, you need to create holes, fertilize them and water them.

By planting evergreens in a summer cottage or garden plot, you can admire their foliage all year round. There are at least five beautiful evergreen shrubswhich have varying degrees of winter hardiness.
