How to Prune a Grapefruit Tree

Prune your grapefruit tree for maximum fruit yield.

Occasional pruning will keep your grapefruit tree vital and fruit-bearing. Along with most citrus plants, grapefruit trees need to be pruned once every two years, anytime between March and late July, before or after the frost period. The same rules apply to areas with no frost.Pruning encourages new growth, prevents rot and bug infestation and keeps your tree looking manicured.

Things You'll Need

• Sharp pruning shears
• Pruning saw
• Work gloves

Instructions

1. Examine the tree from all areas. First, look at the lower trunk and follow it up to where it branches out, called the graft joint. Any shoots growing out of the joint need to be cut away. Next, examine the canopy for dead or pest-infested branches.

2. Using sharp shears, cut away shoots growing from the graft joint. Cut diagonally, right at the base of the shoot. Wear gloves as these shoots can be thorny and tough. Cut away any shoots on the lower branches that are growing downward or close together.As a general rule, cut off about 15 percent of shoots from the tree. Leave new, healthy growth, as it is important for the tree’s vitality.

3. Using a pruning saw, cut off dead wood, stragglers and crisscrossed branches from the center of the tree. Cut away any branches that are entwined together or touching. Make diagonal cuts at the base of the branch. Cutting diagonally lets moisture drain from the cut, preventing rot. Pruning the tree's center creates space and room. Open space prevents pests and fungus, and allows more sunlight and air to reach the leaves.

4. Prune thin branches from the tops and sides of the grapefruit tree to keep it manicured and the canopy minimal. Too much canopy can block sunlight from getting to the core branches.
