Sow seeds individually in small pots of good quality compost, from mid-March to mid-June. Place in a heated propagator, or warm windowsill, and keep just moist.
When seedlings are about 10cm tall, harden off thoroughly. once frosts have passed, plant them out in deeply dug soil, into a large hole filled with plenty of compost or well-rotted manure.
Mound soil in a ring at least 45cm-wide around the base of the plant to divert water to the roots. Water well and cover each plant with a vented bell cloche to protect against cool weather.
Pumpkins have female and male flowers. Males only last a day, so remove them as they fade to reduce the risk of grey mould. if sun levels are low, take out leaves overshadowing the fruits (take out all that have mildew) as this encourages ripening.
