Mulberries

Mulberries, except for dwarf varieties, can grow very tall. After they lose their leaves in winter, they should be pruned to about 8' in order to bring the fruit down to picking level. They like full sun and cannot sit in standing water. They can grow to a 10’ diameter. They are not affected by freezes. They will produce fruit in first or second year.

Care of Mulberry Plants

Planting: Plant during the winter when you purchase the tree (January to early July). Plant in full sun with good drainage. Dig a hole that is wide and deep enough to accommodate the root system. Spread the roots out. The graft, where the tree was grafted onto a hardy disease resistant variety, should be a couple of inches above the soil when you finish planting. Use existing soil only – no amendments. Water in well, and water every day for a few days unless it rains.

Watering: Like all fruit, make sure mulberries get consistent water in the first few years.  Watering can come from rain or a hose.  During the first year, provide the tree with about 7 gallons of water per week, preferably once a week and water slowly.  This will be a little more than 3 minutes with a ½” hose and 1 ½ minutes with a 5/8” hose.  Remember to account for rainfall when determining how much to water with a hose.

Fertilization: Fertilize with a couple of cups of cottonseed meal or other organic fertilizer in late February or early March.

Harvesting: The fruit is ready when it changes color from red to black, but taste when red, for this variety can be sweet before turning black.
