Marrows in Yaverland

Sow seeds on their edge around 9th January - 16th January 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 26th January - 9th February. Handle them gently and keep the compost just moist, not wet.

From 16th January - 30th January, 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 13th February - 20th February 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 2nd March - 17th April, 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 18th March - 29th 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 2nd April while they are still young and tender, then keep harvesting regularly until 29th 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.
