The ultimate guide to when to plant vegetables and why

Cucumbers are a warm-season crop and can be planted in late spring (May to June), after the last frost date. They need full sun and well-drained soil to grow. Harvest cucumbers when they have reached the desired size and are still firm and green. This is usually around 50 to 70 days after planting, depending on the variety. Harvest throughout the summer (June to August) until the vines start to decline.

Lettuce can be planted in early spring (March to April) or fall (September to October), when the soil is cool. It grows best in moderate temperatures and partial shade. Harvest lettuce when the leaves are large enough to use, but before they become bitter or start to bolt. This is usually around 30 to 70 days after planting, depending on the variety. For spring-planted lettuce, harvest in late spring to early summer (May to June), and for fall-planted lettuce, harvest in late fall (October to November) or early winter.
