Spring Gardening in Delaware

During the spring in Delaware zone 7, try planting short season produce in March that prefer cold weather, such as collard greens, green peas, and kale.

These crops will feel much more comfortable in the moderate temperatures of spring, as opposed to the intensity of a Delaware summer. And their short growing period means once temperatures begin to rise, they’ll be ready to harvest and replaced with plants more adapt to the Delaware heat.

Classic home garden produce, such as okra, tomatoes, jalapenos, and acorn squash are great options for mid-to-late spring planting.

For warm weather crops such as these, start seedlings indoors in March. In April and May, once temperatures at night are consistently above 50 degrees, transplant established plants to the garden.
