To prevent cross pollination, you would need to plant different varieties 100 yards (91 m.) or more apart. This is normally not possible in the home garden. Instead, you can select a bloom that you will later collect seeds from the fruit or seedpod.

How close do plants need to be for cross pollination?

Plant at least two compatible-pollen varieties within 50 feet of one another. Pollination will still occur if trees are planted closer together, and may even occur between trees planted farther apart than this, but, for ideal pollination, a 50-foot distance between trees is good to aim for.

How close do fruit trees need to be for pollination?

In planting for pollination, a fruit tree that needs a pollinator needs it close by. A maximum distance of 100 feet is suggested, but the closer the better. Bees that carry pollen are unlikely to fly back and forth if distance between trees is greater. In addition to planting pollinators, other alternatives exist.
