Pumpkin seeds are sown on the windowsill in March-April. Not too early, otherwise the plants will become too lanky before they can be planted out. It is also possible to plant them in the greenhouse, as a staging post in slightly larger pots. In May, the pumpkin plants are put out into the open, where they grow better in the summer than in the greenhouse. They are healthy, greedy plants that appreciate lots of compost and fertilizer.
