We have planted, topped and pruned many cedar tree hedges in the last few years for our customers. With each customer we give the same advice on caring for your cedar hedge. Although cedars are hardy and often seem easy to grow creating a beautiful privacy or back drop in your garden, they do need proper care to not only survive but thrive. Especially with the extreme environmental changes we have witnessed over the past five years. Yes, cedars do evolve and adapt to changes just as humans do but need time and a little helping hand to ensure they do it well. So with that in mind, here is a basic list of care to follow:

Best fertilizer for cedar hedges

Newly planted cedars trees can benefit from a high phosphorous fertilizer. In many cases, adding a fertilizer with a balance similar to 5-15-5 into water and thoroughly watering the newly planted tree can help to reduce transplant shock. Subsequent fertilization should be with a balanced fertilizer or with a higher nitrogen fertilizer with a balance similar to 30-10-10. A good organic alternative organic fertilizer is a combination of blood meal and bone meal mixed with some organic compost from your composter or can be purchased at the local garden center, like Dinter’s or Buckerfield’s.

What are the benefits of fertilizing my cedar hedge

Giving your cedar trees 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. Organic fertilizers at either time will provide a more gentle fertilization that will help protect top soil conditions for the life of the tree.


If your tree is showing signs of under-fertilization, such as yellow leaves, you may want to have the needles tested for nitrogen content. In some cases, soil pH problems, such as a soil that isn’t acidic enough, may appear to be a fertilization problem. If your leaves have enough nitrogen, the yellowing leaves may be caused by another problem.

When can i fertilize my cedar hedge?

Begin fertilizing either at planting or in the spring after the tree has begun to grow. Cedars may appear healthy in the winter, but are often dormant. Fertilizing in the winter can cause a buildup of fertilizer in the soil that may result in spring over fertilization. Stop fertilizing in the fall when deciduous trees begin to lose their leaves.
