How to grow cedar trees?
Giving your cedar more phosphorous at planting will help provide nutrients to the roots as the tree becomes established in the new location. Higher nitrogen levels after the tree is established will help produce more green growth on the tree or shrub.

What to do if your tree has yellow leaves?
If your tree is showing signs of under-fertilization, such as yellow leaves, you may want to have the needles tested for nitrogen content.
Do cedars like acidic soil?

It is not unusual for newly transplanted evergreens to exhibit slow growth until they're re-established.
What does 10-8-15 mean in fertilizer?
A fertilizer analysis of 10-8-15 means the fertilizer has 10 percent nitrogen, 8 percent phosphorous, and 15 percent potassium. Usually the percent of nitrogen content (N) will be the highest number.
What is included in fertilizer package?

How to fertilize a plant?
Plants may be fertilized by either indirect or direct methods. With either method, apply the fertilizer to the entire root zone area. Because of the naturally high oxygen concentrations near the soil surface, a plant’s principal feeding roots are usually within the top 10 to 14 inches of soil. Many roots of mulched plants are located just beneath the mulch on the soil surface. Apply fertilizer to the surface of the soil or mulch; rainfall or irrigation water will carry it to the roots.
