The zucchini is actually one of the Summer squash (marrow) varieties
which are now mostly bush types. When the dark green fruits are picked
small, around 15-20cm long they are called zucchini, when large and full
grown, marrow. For best results they should be picked every 2 or 3 days.
Choose a site in an open warm and sunny position and prepare soil by
digging compost and animal manure into a 1m square to form a hill or
hills 1m apart. Sow 4 seeds to each hill.
Apply plenty of water during the growing season by trickle irrigation rather
than over the foliage because overhead watering tends to onset powdery
mildew particularly toward the end of the growing season. Powdery
mildew can be controlled by spraying with a fungicide as soon as the
disease is noticed.
