Morus nigra Mulberries have been prized for centuries, and we’re happy to offer a variety that even gardeners with very limited space can accommodate. Ripening continuously throughout the season, the multipurpose fruit is good for jam, pies, juice and wine. Wildlife relish the fruit, and the leaves are the sole source of food for silk worms!
After unpacking, allow the plant a few days to gradually acclimate to full sun exposure and nighttime temperatures. Mulberries prefer slightly acidic soil (pH approximately 5.5-6.5). Choose a location in full sun with good drainage. Dig a hole approximately twice the size of the pot that the plant arrived in. Set the mulberry slightly higher than the existing soil line, backfill, gently tamp to firm the soil and remove air pockets, and water well. We recommend removing the first year’s blossoms as they appear. This diverts the plant’s energy and allows it to establish a strong root system. If you choose to keep your mulberry in a pot, choose a container that is at least 1-gallon capacity for the first growing season, and plan to up-pot as the plant grows.
Water regularly during the first growing season, but do not allow the soil to become soggy. Mulberries require about 1 inch of water per week during the growing season. Spread about ¼ cup of Territorial’s Complete Fertilizer around the base of the plant in early spring. Distribute the fertilizer evenly from the canopy line of the plant in towards the trunk, but avoid piling the fertilizer against the trunk. Scratch the fertilizer into the top of the soil and water in. Prune plants in late winter if necessary to maintain shape or anytime to remove dead wood.
Start picking berries in summer. The berries will be large, very dark blue and sweet when ready.

Pests & Diseases
Mulberries are generally not bothered by pests or disease
Mulberries prefer moist, slightly acidic (approximately 5.5-6.5 pH), well-draining soil rich in organic matter. Peat moss, sawdust and composted oak leaves are good amendments to add humus and lower the pH of the soil.
Full sun to part shade
15-25 pounds per plant
