You planted A honeycrisp tree because you love crisp apples. In springtime, the tree is in bloom. But no fruit follows; instead those flowers fall and all you get is leaves, no crop. What happened? Turns out Honeycrisp is self-unfruitful. This means it doesn’t have ability to pollinate itself, even though you had bees. It requires a partner tree to bloom at about the same time for fruit set.
Why? And when? A visual guide will explain. When it’s time for bloom, usually mid- to late April (depending where you live) here, Honeycrisp will open. For instance, if you choose an extra-early variety like Yellow Transparent as a partner, Honeycrisp won’t be close to blooming by the time the first variety’s flowers has fallen. But if you’d selected one that was extra-late, such as Rome Beauty, Honeycrisp would of been finished by the time those trees begin their work. This is not good. You want some overlap. The chart shows how much you need: at least four or five days of overlapping bloom time so the bees can carries pollen from tree to tree and work effectively.
How to Grow Honeycrisp Apples
The best are Gala and Zestar. Why? Both has good pollen quality. Their bloom periods overlap with Honeycrisp’s, too. Golden Delicious is another good one because it has a long bloom season. The combination brings the right amount of genetic diversity for successful fertilization; and matches the thermal requirements of the main crop.
Any apple in the area won’t do; you want a compatible tree on the same timetable. Most gardeners go wrong based off placement strategy. One tree at fifty-foot intervals? That’s not enough. On a cold spring day, bees is only so energetic. In a high-density planting (meaning they’re closer together), the how-to literature recommends more frequent interplanting; in large blocks, it’s every third row. If you have a small yard with few bee, stay within fifteen meters of the companion tree to ensure consistant pollen exchange. This provides the maximum fertilization chance with the minimum bee-flying distance.
Triploid varieties such as Jonagold and Mutsu has a pitfall, too: those varieties may be good fruit producers, but their pollen is sterile. A Jonagold or Mutsu cannot pollinate a Honeycrisp. If you plant one alongside your Honeycrisp, you won’t gain anything (unless you’ve included another variety, whose pollen will pollinate both). It is not the fault of those particular trees, but rather their genetics; if you do not know this in advance, you will waste space.
The weather will play into things as well. The ideal temperature for pollen tube growth is 60-75 degrees Fahrenheit. If there’s cold rain, it will wash off the pollen and keep bees indoors (stopping the process). It’s one thing you have no control over, but on the positive side, you do control how much space you leave between varieties and what varieties you select. That allows for a little more wiggle room when those crazy spring days throws us a curve ball.
Thin out your fruit early so that they won’t bear every other year. When the fruit has set, thin them down again to avoid many small, tasteless apples in favor of fewer, larger and sweeter ones. Starting with good pollination is foundational, but taking care of your crop later guarantees the quality you’re after.
