Spring Gardening in Rhode Island

Zones 6 and 7

During the spring in Rhode Island zones 6 and 7, try planting short season produce in March that prefer cold weather, such as carrots, iceberg lettuce, and broccolini.

These crops will feel much more comfortable in the moderate temperatures of spring, as opposed to the intensity of a Rhode Island 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 Rhode Island heat.

Classic home garden produce, such as patty pan squash, yellow squash, butternut squash, and green beans 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.

Zone 5

In Rhode Island growing zone 5, spring is considerably cold compared to most other areas. As a result, the viable growing season in these locations is fairly short.

To get the most out of your garden in Rhode Island zone 5, seedlings should to be started indoors. We also recommend using a blanket of straw to help protect transplants from a surprise frost.

With so much of the growing season experiencing cooler temperatures, focusing on frost tolerant crops is a great strategy for success. Vegetables such as onions, kale, collard greens, and cabbage can usually be planted in late April or May for zone 5. Cool weather crops that have a bit longer growing period, such as Brussels sprouts, parsnips, and artichokes, are another great option for the colder areas of Rhode Island.

But at the end of the day, for most common garden vegetables in Rhode Island zone 5, planting will have to wait until things warm up in June.

Fall crops for Rhode Island zones 6 and 7 are typically planted around July and August. This should give the plant enough time to establish itself before cold weather begins to set in. Think cold-loving crops such as collard greens, cabbage, and broccolini. Hardy root vegetables and durable leafy greens are great options, especially if you’re looking for something to plant in September or early October.

Zone 5
