How to fertilize a cedar tree is one of the topics covered by the Garden Guides.
Cedars are a very hardy tree that does well without fertilization.Enhancing the growth of your cedar can help.How recently you planted the cedar and the type of soil in which it grows will determine the kind of fertilization you need.
Depending on the type of soil your tree grows in, the best fertilization for it will be based on that.cedars prefer acidic soil.The soil should be tested with a pH test kit.There are many home and garden supply stores that sell the test kits.
Newly planted cedars can benefit from a high phosphorous fertilization.Adding afertilizer with a balance similar to 5-15-5 into water and thoroughly watering the newly planted tree can help to reduce transplant shock.It's a good idea to use a balanced or higher nitrogenfertilizer after fertilization.A combination of blood meal and bone meal is a good organic alternative.
As the tree becomes established in a new location, you should give your cedar more phosphorous at planting.Nitrogen levels will go up after the tree is established.At either time, organic fertilization will provide a more gentle fertilization that will help protect soil conditions for the life of the tree.
If your tree has yellow leaves, you may want to have the needles tested for nitrogen.Some soil pH problems, such as a soil that isn't acidic enough, may appear to be a fertilization problem.If your leaves don't have enough nitrogen, you may have a problem.
