Marrows are Cucurbits and belong to the same plant Family courgettes, zucchini, squash and cucumbers. They are grown in a similar way. The fruits are left on the plant to reach a larger size. The skin maybe green, light yellow or white. There are many varieties. Marrows need regular feeding and reliable watering. Sow in small pots or deep seed trays and grow indoors, planting out, after 4-6 weeks after the last frosts. They can be sown directly into the garden after the last frosts. Grow on raised mounds of soil with a heavy covering of compost. Marrow are a warm weather plants and cold conditions results in slow growth and low production. When sowing the seeds align them vertically and plant about 2 cm (1 inch) deep to stop the seeds rotting. Allow about 75–90 cm (2-3 feet) between plants as they can grow quite large. Feed the plants regularly once the fruits start to develop. Harvest the small fruits leaving about 4 per plant to grow to full size.
Harvest at the end of the season. Let the skins to harden before picking. Unlike courgettes, the skin and seeds are not eaten. Marrow can be sliced and then steamed, boiled or lightly fried. They are delicious stuffed and baked. They can be used in soups and stews and can be used to make chutneys.
Seed Depth: Sow seed in small pots or deep seed trays as Marrows are frost tender. Sow seeds about 20 mm (1 inch) deep. Sow seed directly into the soil after the last frost.
Space between plants: Space plants about 90-120 cm (2-3 feet) apart. Space rows 90 cm (3 feet) apart. Plant in raised mounds
Harvest Time: Harvest in about 12-17 weeks, but smaller fruits can be continually picked as the plants grow and eaten as zucchini.
