How to Fertilize Flowering Trees


Fertilizing flowering trees is a great way to enhance the beauty of your landscape. Proper fertilization should be done annually to encourage blooming and increased healthy growth. When choosing a fertilizer for your flowering trees you can use either a liquid or powdered form; they provide equal benefits to the trees.

Step 1

Apply fertilizer in the fall or early spring. Choose a fertilizer that is a bloom booster for your flowering trees, to increase the bloom production in the spring. This type of fertilizer is a 5-30-5 blend, which is a compound blend of 5 percent nitrogen, 30 percent phosphorous and 5 percent potassium.

Step 2

Spread the fertilizer at the base of the flowering tree. The amount of fertilizer depends on the age and size of the tree. As a general rule use 1 3/4 to 2 pounds of fertilizer for every 100 square feet of soil at the base of the tree. If using a liquid fertilizer that requires dilution with water, follow the directions on the package.

Step 3

Water the soil around the tree thoroughly to increase the absorption of the fertilizer. This step is unnecessary if you use a liquid fertilizer.

Tips and Warnings

  • If using a sprayer to fertilize, set the spray to a direct spray in order to place the fertilizer at the base of the tree.
