Loquat

Keep a mulch ring, held back off the trunk

Maintain a 2 to 6 inch layer of bark, wood chips or similar mulch out under the canopy, and keep it pulled back 8 to 12 inches from the trunk. Top it up as it breaks down. Mulch holds soil moisture through the dry stretches while the tree is filling fruit, and it keeps turf and the mowers and trimmers that follow turf away from the trunk. Piled against the bark instead, it holds the trunk wet and invites rot.

Feed once the crop is off, and keep the nitrogen modest

With the crop picked, give a bearing tree a complete fertilizer such as 6-6-6, 8-3-9 or similar material. This is the summer feeding in a bearing tree's schedule of two to three applications a year: one just before or at the fall bloom, one in March while the crop is still on, and this one after harvest. Let a soil test set the rate instead of guessing high. A bearing loquat is fed two to three times a year, and the post-harvest feeding rebuilds the tree after a crop it carried all winter. Keep the rate honest: excessive nitrogen pushes soft, succulent new growth, and succulent shoots are exactly what fire blight infects most readily.

Thin each panicle to 4 to 10 fruits

Once fruit have set and are still small, hand-thin each fruiting panicle down to four to ten fruits, pulling the smallest, the misshapen and the ones wedged tight against a neighbor. An obviously overloaded cluster can be thinned back at the flower stage instead. A loquat panicle sets far more fruit than it can ever fill, and the fruit compete for the same sugar. Thinning to four to ten increases the size of what remains by 25 to 100 percent.

Prune for height and cut out fire blight strikes after harvest

With the crop picked, bring the tree back to a working height of 6 to 12 ft and thin the canopy so air moves through it. Cut every blackened, blighted shoot 12 to 18 inches back into clean wood, and disinfect the shears between cuts. On trees in their first year or two, tip any shoot longer than 2 to 3 ft to force it to branch. Where winter cold damages loquats, hold off pruning until new shoots emerge so you can see what actually survived. This is the window between harvest and the fall bloom, so you are shaping the tree without cutting off the flower buds that carry next year's crop. Cutting blight well below the visible edge is the only way to get ahead of bacteria that have already travelled down the shoot past the blackening.

⚠ Disinfect between every cut, not just between trees - the shears themselves are how fire blight gets carried from a strike into healthy wood.

Fire blight: watch the blossoms while they are open

While the tree is flowering, check the clusters after every warm rain for blossoms that wilt, blacken and then hang on the shoot instead of dropping. Mark every strike you find so you can cut it out after harvest. Do not reach for an insecticide here - the bees working those flowers are not a problem you can spray away. Fire blight bacteria move in rain and on insect visitors including bees, ants and flies, and the open flower is the doorway. From there the infection runs downward into the shoot and on into larger wood, which is why blighted growth blackens from the top down.

⚠ Never apply an insecticide to a tree in bloom.

Protect the crop through winter freezes

Loquat carries its flowers and swelling fruit straight through the cold months, so track the forecast and cover a small tree, or run a heat source under it, whenever a night below 27 F is coming. Siting matters more than any blanket: a tree in a courtyard or against a south-facing wall rides out the same freeze that strips one standing in the open. The wood itself is hardy down to roughly 8 to 12 F, but flowers and developing fruit are killed at 27 F - so a freeze can take the entire crop and leave you looking at a tree that appears perfectly healthy.

Bag the fruit panicles where fruit flies are established

Right after thinning, slip a paper bag over each entire fruiting panicle and close it around the stem, then leave the bags on until you pick. This is worth the work mainly in areas where the Caribbean fruit fly is present, such as peninsular Florida. Paper bagging the whole panicle is the recommended defense against the Caribbean fruit fly, which stings developing fruit and ruins it from inside; the bag also shelters the fruit and brings the panicle along somewhat faster.

Pick at full color - loquat does not ripen off the tree

Wait until fruit reaches nearly full to full color, then taste one or two from the tree before you strip a cluster; the color your particular tree tastes right at is the color to pick at from then on. Ripe fruit refrigerated in a plastic bag holds for several weeks. No further ripening happens once a loquat is picked, so fruit taken early stays sour permanently - there is no windowsill fix. The wait is long: after bloom, fruit takes four to five months to ripen in the spring, so let it finish on the branch.
