Mulberry
Morus alba
Zones 4–10
Growing
When planting your mulberry tree, handle the root system with extreme care, as the roots are quite brittle and prone to damage during the transplanting process. While these trees are remarkably hardy and can withstand a hard freeze, they thrive best in rich, fertile, well-drained loam. If you are growing them in a container, ensure the medium provides excellent drainage to prevent waterlogged conditions.
Maintenance is relatively low-effort, but timing is everything when it comes to pruning. You should prune your tree during the winter while it is in its dormant phase, focusing only on removing dead wood or branches that are poorly positioned. Avoid pruning when the sap is flowing, as mulberry trees are known to bleed heavily when cut during their active growth period.
To enjoy the best flavor, harvest the fruit when it is fully ripe and ready to use, as the berries will not continue to ripen once they have been picked from the branch. Because the fruit is delicate, keep it unwashed until you are ready to eat it. If you have a large harvest, you can preserve the berries by freezing, drying, or canning them.
