Evergreen trees don't need much fertilizer, if any. It is very easy to fertilize an evergreen. Fertilizing evergreen plants are only required if the tree loses its dark green color due to a lack of nutrients.

What a plant needs

First, evergreens normally only need sunshine and water, but a plant also needs 17 nutrients for normal growth. Hydrogen, carbon and oxygen are drawn from the air. Nitrogen, phosphorus, potassium, magnesium, calcium and sulfur are macronutrients that are extracted from the soil in large quantities. Micronutrients such as iron, zinc, molybdenum, manganese, boron, copper, cobalt and chlorine are also extracted from the soil, but in much lower doses than the macronutrients.

Bad evergreen growth

If an evergreen has problems with limited growth, it is most likely caused by nitrogen, phosphorus, or potassium. Evergreen plants, like any other tree or shrub that suffers from poor growth, typically exhibit one or more of the following symptoms: light or yellow leaves or needles, dying off at the tips of the branches, wilting, branch growth that is shorter than expected; and more.

Poor soil conditions are usually to blame if an evergreen suffers from poor plant growth. Factors such as poor soil ventilation or moisture, incorrect pH values, nutrient toxicity or deficiency or illness lead to poor plant growth in evergreens and other plants.

When to fertilize evergreens

When deciding whether to fertilize an evergreen tree or not, it is best to do a soil analysis of the area around the tree. A soil analysis shows whether the soil lacks nutrients or whether it has an excess of nutrients. Soil analysis also shows the amount of organic matter in the soil and the pH of the soil.

How to fertilize evergreens

If an evergreen needs fertilizer, it is important that the fertilizer is absorbed by the soil and then taken up by the plant from the soil. Fertilizer should never be applied directly to a new planting hole.

sum it up

When caring for trees and shrubs, not all trees and shrubs are the same. Research is the key to every single plant that is worked with. Lawn care services, tree care companies and nurseries are excellent resources to ask questions and get recommendations from.

If you are unsure of what to do, how to do a job, or simply have too little time, it is best to call a professional to make sure the job is done correctly. Take a look around, ask friends or family, and research the Better Business Bureau for a company you can trust.
