Removing blooms from an apple tree is basically just pruning back the blossoms to encourage new growth each year in the fall. When you remove the blooms each year, it will help thin out the fruit production to ensure that all the grown fruit gets enough nutrients and room to grow, resulting in a better apple crop.
Make sure the ladder is securely positioned up against the tree for you to climb up it to higher limbs.
Use the pruning scissors to remove the blossoms or blooms that have a black interior, which means they are diseased or dead. It is important you trim the bad blooms and keep the good ones, or you could do more harm than good to your tree.
Use the shears to trim off the small apples when they are about the size of a dime. Apples bloom in clusters of about five to six blooms. Trim back three to four of these on each cluster, choosing the smallest blooms and those that appear the weakest.
Space out the remaining apples so they are about six inches apart from each other. This encourages maximum fruit production and new growth for the following season.
Dispose of all the apples and blooms you cut off with the shears.
