Marrows in Beanhill

Sow seeds on their edge around 17th March - 24th March in small pots of warm seed compost. Keep them at 21–24 °C and do not sow too early, because marrow seedlings grow fast and can suffer if they become root-bound.

When the first true leaves appear, prick out or move each seedling into a larger pot at 3rd April - 17th April. Handle them gently and keep the compost just moist, not wet.

From 24th March - 7th April, move the plants outside for short periods each day so they adjust to wind, cooler nights and direct sun. Keep them under fleece or in a cold frame at night if conditions are still unsettled.

Set plants out at 21st April - 28th April once frost risk has passed and the soil is warm. Plant into rich, well-watered mounds or pockets, then water in thoroughly without wetting the stem.

From 8th May - 23rd June, keep the plants centred on their mound and tuck the stems back if they stray. In a small garden, use a short frame or straw to keep fruit off damp soil and reduce rot.

From 24th May - 3rd November, water deeply around the plant rather than over the leaves, and feed every 14 days once the first fruits set. Keep the compost or soil evenly moist so the fruit fills properly and avoids bitterness.

Pick fruits from 8th June while they are still young and tender, then keep harvesting regularly until 3rd November. Cut them with a knife or secateurs so you do not damage the stem, and check plants every few days for fruits that are ready.
