How to Manage Pests

Pests in Gardens and Landscapes

Time to plant

Cucurbits are warm-season crops that can be grown over a wide climatic region. However, they do not tolerate frost. Summer squashes thrive in somewhat cooler climates than cantaloupe or watermelon. They can also be productively grown between the frost-free periods, as they are short-season crops.

Winter and summer squash is suitable for a small garden if compact varieties are grown.
