Cucurbits are members of the squash family.
This family is a thick-skinned group that grows on vines and keeps its seeds in a line down the center of their fruit. The squash, or cucurbit, family is made up of cucumbers, gourds, luffas, melons, pumpkins, squash, watermelons, and the inevitable zucchini. These plants love hot weather and many of them have protective bristles.
Most of the 975 cucurbit species are susceptible to frost and many are trailing annual vines with tendrils. They tend to have large bristle-haired leaves and both male and female flowers (monoecious).
Cucurbits have relatively large seeds and they do not transplant well after the first 3 weeks. It is best to directly sow seeds in the ground. As a group, cucurbits grow fast. They need very little nitrogen, but they use a lot of potassium and phosphorus. Side dressing plants with aged compost goes a long way toward creating a big harvest.
Cucurbits prefer full sun and deep, infrequent watering. During the hottest days of summer, it is a good idea to keep an eye out for wilting leaves, a sure sign that you waited too long to water!
These semi-climbing plants benefit from the use of trellises, stock panels, or ladders. Heavier fruits can be supported using hammocks or net bags. This keeps the fruit off the ground, preventing fungal disease, rot, and pest damage.
Cucurbit pests and diseases
Regularly watering in the early morning allows cucurbit leaves to dry out before evening, preventing powdery mildew and other fungal diseases. Because of the wide leaf coverage of most cucurbits, weeds are seldom a problem. Cucurbits are frequently attacked by cucumber beetles, flea beetles, squash vine borers, and squash bugs, so squash those bugs whenever you see them!
Be sure to harvest fruits regularly, to ensure continuous production. Once plants believe they have completed their reproductive cycle, you generally won't get any more fruit.
