Item: 7376-A
stock details: 3–6' bare-root trees
Morus latifolia

30 × 20' Hardy variety with large dark purplish-black seedless berries up to 2" long. Fruit is very sweet and juicy; similar in size and taste to Illinois Everbearing. Great fresh eating and good for drying. 

Fruit begins to ripen in early July. While Illinois has a longer ripening season, Kokuso may be a hardier tree.

Widely thought to be of Korean origin, but may have first been selected in Japan as fodder for silkworm production due to its enormous leaves. Precocious and self-fruitful. Zone 4.

Additional Information

Mulberries Morus spp.

Sweet flavorful purple-black 1" blackberry-like fruit is delicious fresh, in sauces, pies, fruit leather or smoothies. What fruit you don’t pick, the birds will. Great tree for viewing a huge variety of birds up close. Plant it next to the chicken pen where it will rain chicken feed into the yard for several weeks, or put down a sheet to collect the fruit as it falls.

Dense round-topped tree is one of the last to leaf out in the spring. Fast growing, even in poor soils. We offer grafted female varieties, which are self-fruitful.

Growing Mulberries

  • Soil: Adaptable, but prefers moist well-drained soil. Rugged! Withstands pollution, drought, wind and salt.
  • Sun: Full sun to part shade.
  • Pollination: Mulberries are dioecious, but female trees do not need a male to set fruit. You just need one!
  • Spacing: 20–30' apart
  • Planting: Consider a site with northern exposure to delay flowering. See our planning and planting and pests and diseases pages for instructions on soil prep, planting and pest control.
