Edible Cherry Trees Pollination and Varieties Guide

Pollination is important as without it trees will not produce fruit. Most trees require insects to transfer pollen between male (anthers) and female structures (stigma), ensuring fertilisation. Some trees, however, can self-fertilise. Without fertilisation, trees would be unable to propagate and the production of seeds and fruit would be useless. In the case of cherry trees, some are self-fertile and others are self-sterile, depending on the variety.

Cherry trees require another variety flowering at the same time to ensure fertilisation. They are henceforth put into flowering groups from 1 (very early) to 5 (very late). A cherry tree can be partnered with another in a group that is plus or minus 1 (+-1) its own group. To make matters more complex, even if some varieties have their flowers open at the same time they may not pollinate. They are henceforth put into groups (from A-O). Cherry trees thus require another tree in the same group and within plus or minus 1 flowering groups.

Thankfully, this is where universal donors come in that will pollinate any cherry tree within plus or minus 1 flowering group. We henceforth recommend, you pair one of these fertile varieties with another. As previously mentioned, some cherry trees are self-fertile and do not need to be paired with another. However, they do benefit from cross-fertilisation, so for heavier crops we recommend pairing.

Another factor you need to consider is the date of the last frost in your location. Frost can be extremely damaging to blossoms and will reduce your crop. It is henceforth important to choose trees in the latter flowering groups if you have a late last frost. Your locations date can be found using this resource online. It should also be noted that bad weather such as rain and wind will prevent pollinating insects from visiting your blossoms and could reduce your crops.

It is important to note that cherry blossom trees will not fertilise edible cherry trees, although acid cherries will. As cherry trees are somewhat common, it is possible that another tree could fertilise your own tree. As bees forage widely, a tree within 30m could fertilise one of your own, although it is simpler to plant another within the immediate vicinity. If you believe pollination has been disrupted, you can pollinate yourself by using a paintbrush and transferring pollen from one plant to another.
