Pick mangosteen when the rind is reddish-purple and slightly soft. Take it by hand or a cutting pole, because a dropped fruit bruises and a greenish-yellow fruit will not sweeten.
Pick when the rind is reddish-purple and slightly soft
| Factor | Recommended | Avoid |
|---|---|---|
| Color | Dark reddish-purple to red-purple, with a slight give | Do not pick light greenish-yellow fruit with only a few pink specks |
| How | Hand-pick from a ladder, or cut the stem with a pole and a catching bag | Do not let the fruit fall |
| Maturity | Fully developed on the tree; a slightly underripe fruit can finish if it already has color | Do not pick hard, pale fruit and wait for it to sweeten indoors |
| Handling | Handle gently; the rind stains and the latex is bitter | Do not pile fruit in a deep crate where the bottom layer bruises |
Ripeness is the full purple color plus a slight softening. You can pick a little early if the fruit is already colored, but a pale fruit will not make full flavor off the tree. [1] Home fruit in Florida is uncommon, so taste one fruit before you strip the tree. [2] A backyard tree has fruited in a warm coastal pocket after years of care; cropping is still irregular. [3] mangosteen is the thick purple fruit with white segments. Pick that fruit, not a pale one. [4]
When do I pick mangosteen?
When the rind is reddish-purple and slightly soft. Do not pick pale greenish-yellow fruit.
How to harvest mangosteen
- Look at the rind. Wait until it has turned reddish-purple over most of the surface, not pale with a few pink dots.
- Press gently. The rind should give a little. If it is still hard and green, leave it.
- Hold the fruit and cut or twist the stem. Use a pole with a bag if the fruit is high. Do not shake the branch.
- Set fruit in a single layer in a shallow tray. Do not drop them into a bucket.
- Keep them cool and out of hot, dry air. Warm closed storage holds them about three weeks before the rind toughens.
Do not pick it greenish-yellow — it will not sweeten off the tree
A fruit that is still light greenish-yellow with scattered pink spots does not ripen to full flavor after you take it. Wait for color on the tree. Once the rind is purple, cool the fruit; it will not get sweeter on the counter the way a banana does.
Do mangosteens ripen after I pick them?
Only if they were already colored on the tree. Pale fruit will not sweeten. Cool purple fruit; do not wait for a green one to turn.
Wait for purple color on the tree, cut the stem, and keep the fruit in a shallow tray out of heat.
FAQ
How long do mangosteens keep after I pick them?
About three weeks in dry, warm, closed storage before the rind toughens. Cooler air holds them longer, but the rind still hardens if you wait too long.
