About Dunja
Dunja is an organic hybrid zucchini that produces dark green, straight fruit on an open, nearly spineless plant that is easy to reach into at harvest. It is popular with home and market growers for its early, heavy yields and strong disease resistance, including tolerance to powdery mildew and several mosaic viruses.
Growing Dunja Zucchini
The open plant habit makes harvest easier; space plants about 2 to 3 feet apart in full sun. Its disease resistance helps it keep producing later into a humid summer when powdery mildew often sets in. Pick fruit at 6 to 8 inches and harvest frequently.
