When we’re not tooling around the yard with the kids on bikes, we care for a small orchard with 14 trees! The bulk of these are peaches; we have 3 older trees that produce well but lose a branch or two every year; one “middle-aged” tree that’s pretty big but still developing its shape; and two very young trees that just started fruiting last summer. Over the past 4 years, I’ve been learning a lot about pruning and thinning the fruit. Two years ago, there was 95% crop loss of peaches and thinning wasn’t an issue. Last year, we lost some branches because they were so laden with fruit! My trees have benefitted immensely from clear online and in-book guides to pruning, but I found it extremely difficult to visualize what a branch should look like when properly thinned of fruit. Here’s what I wish I’d had when I was starting out!Â
Before thinning fruit, I wait until it’s somewhere between quarter and golf ball sized. Realistically, I need to give myself this window, because there are six trees and one me thinning fruit. If I only had one tree, I’d probably err on the side of bigger fruit – this ensures that the pits of the fruit won’t crack in the mature fruit. I take my hand pruners (the smallest I have) and use them to clip the fruit cleanly from where it grows, so I don’t damage the tree by pulling.
- Remove all small or unformed fruit (this will frequently fall off in your hands)
- Remove fruit from the underside of branches where it won’t find sun/ripen as quickly.
- Remove fruit from places where it touches or will grow into other branches – this will split the skin of mature fruit.Â
- Space remaining fruit 4-6 inches apart. I find it useful to imagine the amount of space the fruit will need when it is full-sized.
- With remaining fruit, take into account the size/sturdiness of branches – if they’re bending under the weight of the baby fruit, they’ll probably sink even lower as fruit grows! Add support or thin accordingly. With small, weak branches, I often leave only the biggest baby peach on; these branches will frequently die and be pruned off the following spring.
