Prune lychee after harvest, keep the canopy about 10 to 15 feet, and do not tip prune after August.
Prune after harvest, and keep the tree 10 to 15 feet
| Factor | Recommended | Avoid |
|---|---|---|
| When | Right after harvest, while there is still a long warm spell for new shoots to harden | Do not tip prune after August |
| Height | Keep a bearing tree about 10 to 15 feet so you can pick and spray | Do not let the top shade out the low fruiting wood |
| Low wood | Leave the lower branches; they fruit and shade the ground | Do not limb the tree up like a street tree |
| Hard cut | A heavy cut-back on a huge tree is possible, but you will lose a crop or two | Do not climb a 30-foot canopy; hire an arborist |
The harvest cut already takes some wood. After that, thin the top so lychee stays a tree you can reach. [1] New shoots then have time to mature before cool weather, which is what sets next spring's flowers. [2] A late cut into August still has warmth left; a September tip cut does not.
When do I prune a lychee tree?
Prune as soon as the fruit is off. Late summer cuts still have warmth left to harden new wood.
How tall should I keep it?
Keep a bearing tree about 10 to 15 feet. A taller tree is harder to pick and more likely to lose the low canopy.
How to prune a lychee tree
- Wait until the last ripe clusters are off the tree.
- Take a few crowded uprights back to a wide crotch so laterals can take over. [3]
- Shorten the tallest tops until the canopy sits about 10 to 15 feet.
- Leave the lowest branches; they carry fruit you can reach and they shade the soil.
- Stop once the tree is open enough to walk around. A hard cut every year is not required.
What fails if you prune after August
A tip cut after August pushes a late flush of soft wood. That flush does not harden in time, so the tree skips bloom in spring. [4] Leave the saw in the shed once nights start to cool. Pick the fruit on Harvesting Lychee; that cut is not a substitute for this size work.
Finish the size cuts while the weather is still warm, then leave the tree alone so the new wood can harden.
FAQ
Can I keep a lychee as a short hedge?
You can keep it short with yearly after-harvest cuts, but a hard shear into old wood will cost you a crop. Aim for a small tree, not a clipped hedge.
