When to Plant in Newark, NJ

In Newark, New Jersey, the gardening calendar is defined by a median last spring frost date of April 3 and a median first fall frost date of November 7, providing local gardeners with about 176 frost-free days to work with each year. These dates create a unique window for planting various crops and flowers that thrive in local conditions, allowing for a diverse gardening experience throughout the growing season.

The humid temperate microclimate with four distinct seasons is particularly favorable for a range of vegetables and flowers. Crops like tomatoes, peppers, and zucchini thrive well due to warm summers that aid their growth and fruiting. On the other hand, crops such as sweet potatoes, which prefer a longer growing season and warmer conditions, can struggle due to the limitations of the spring freeze. Similarly, certain herbs like basil may not survive unexpected late frosts.

What to plant now in Newark

Spring: Start planting cool-season crops like peas, lettuce, and radishes after the last frost date on April 3, as these plants flourish in the cooler temperatures.
Summer: After the frost-free period begins, plant warm-weather crops such as tomatoes, peppers, and beans from late April to early June to ensure a bountiful harvest.
Fall: In late summer, prepare for fall planting of crops like kale and hardy greens which can withstand the cooler weather that follows the first frost on November 7.
