Tips & Advice:
Sowing Indoors
Sow seeds individually on edge in small pots of firm, moist seed compost, 2cm deep. Place in the warmth, 15-18°C and keep moist. As seedlings develop, grow on under cool, light conditions, but not in direct sunlight.
Planting Out
Gradually accustom young plants to outdoor conditions for 2-3 weeks before planting out to their cropping positions, after risk of frost has passed. Water and feed regularly.
Sowing Outdoors
Water sowing positions, then sow two or three seeds close together in a group 2cm deep, 90cm apart. After germination, leave only the strongest seedlings in each group. Keep well watered in dry spells and feed regularly with a liquid fertiliser.
Extremely rarely, marrows may produce very bitter fruit that cause stomach upset. This can be tested by licking the cut surface of one fruit per plant; bitter fruit should not be eaten.
