(Best months for planting Marrow in USA - Zone 5a regions)

S = Plant undercover in seed trays. P = Plant direct in garden where they are to grow.


  • Grow in seed trays, and plant out in 4-6 weeks. Sow seed at a depth approximately three times the diameter of the seed. Best planted at soil temperatures between 20°C and 35°C. (Show °F/in)
  • Space plants: 90 - 120 cm apart
  • Harvest in 12-17 weeks.
  • Compatible with: Peas, Beans, Onions, Sweetcorn
  • Avoid growing with: Potatoes
  • Young marrow

This looks like a large version of zucchini/courgette. Skin is light yellow or white. Grow on raised mounds of earth/compost. Mulch to retain moisture and reduce weed growth. Frost tender.

Powdery mildew can be a problem especially in humid weather.
