(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 (can grow in same bed): Peas, Beans, Onions, Sweetcorn
  • Avoid growing in same bed: Potatoes
  • Young marrow

This is a large, well grown version of zucchini/courgette. Skin maybe light yellow or white. Grow on raised mounds of earth/compost. Mulch to retain moisture and reduce weed growth.

Powdery mildew can be a problem especially in humid weather.

Do you mean the light green ones ? shaped like a bell ?. I have planted some this season - they've gone mad (people are avoiding me in the street in case I give them another zucchini). They are called Lebanese zucchinis and my husband stuffs them - the seed is faily readily available - think I got mine at Bunnngs

A marrow is NOT an over grown zucchini, they are members of the same genus, but different plants. I live in England, and use marrows a lot in August - December. I have a family member in Q L D, and visit every year. Would like to grow some while I'm there, but can not find any seeds!!

Marrow also makes a delicious marrow and roasted garlic soup which is equally good whether served hot or cold
