Choose the Right Location:

When choosing a tree to plant, one of the most important questions to ask yourself first is, “Is this specific tree suited to my specific climate?” If you can answer, “yes”, the next step is to consider your specific site conditions. Though mulberries are a pioneer species and will grow in disturbed soils and tree lines, they prefer full sun (“the more sun, the more fruit”) and moist, well draining, loamy, fertile soils. Due to the fruits’ juicy nature, it may be a good idea to choose a location where the dark purple juice stains of the unharvested fruits will not be a nuisance. It’s also important to keep in mind that mulberries have an extensive root system and so it is best to avoid planting them near foundations, sidewalks, or underground utilities.

Do I Need to Plant in Groups?

Mulberry trees are self-fertile and, therefore, do not require a second tree in order to bear fruit. However, having more than one variety generally increases fruit yield and size. If you are planting more than one, it is important to give the trees adequate space. Dwarf and weeping varieties generally require 6-10 feet between trees while semi-dwarf and standard size mulberries need 15-20 feet unless you plan to keep them pruned to a smaller size.

Provide Adequate Water and Mulch:

Mulberry trees are relatively drought-tolerant once established but require consistent watering during certain stages of their growth, especially when young or producing fruit. For the first 1-2 years, water deeply and regularly 1-2 times per week. Once the tree is well-established (3+ years old), water only during extended dry spells. Adding a layer of mulch (2-3 inches) around the base of the tree (without touching the tree) helps to retain moisture, regulate temperature and reduce evaporation. The mulberry does not like “wet feet” (soggy roots) though, so it’s important to ensure the soil has good drainage to avoid root rot.

Signs of Underwatering and Overwatering

Underwatering:

• Wilting Leaves
• Yellowing or drying leaves, especially at the edges
• Premature fruit drop

Overwatering:

• Yellowing leaves that fall off easily
• Mushy or rotting roots
• Stunted growth
