The meyer lemon tree, according to the University of Florida Extension, is a tree native to China. Fruit from the tree is edible and is slightly sweeter than a true lemon tree's fruit, due possibly to its crossing with the mandarin tree. The tree grows 6 to 10 feet tall, but it is possible to prune it to a smaller size, stunting its growth. Pruning also shapes the tree and promotes proper fruit growth.
Remove suckers from the bottom of the tree while it is growing to promote proper development, says meyerlemontree.com. Suckers rise from the soil surface and from the trunk of the tree, and can be identified by their different foliage. Remove suckers using a set of pruning shears.
Remove dead, broken or diseased limbs from the meyer lemon tree, cutting the branch away as close to a healthy bud as possible, or all the way back to the collar of the branch. The collar is the small bump in the trunk where the branch extends from the rest of the plant. Make cuts next to a healthy bud at a 45 degree angle, or cut branches at the collar flush.
Prune away long, thin branches that are thinner than the diameter of a pencil. Thin branches do not hold fruit.
Cut away any stems that are crossing each other or rubbing against each other, keeping the healthier of the two branches. This increases airflow inside the tree and increases fruit production.
Train the plant to the height you want by trimming away the top of the plant until it is at the height you want. Cut the top back to healthy buds to promote side growth.
