The warm springs and long falls make it excellent territory for tomatoes, peppers, and cool-season greens. Community gardens and rooftop gardening are popular innovations for space-constrained urban growers in Newark.

In Newark (last frost around April 5), aim to direct sow or transplant butternut squash outside around April — approximately 2 weeks after your last expected frost. Starting seeds indoors 3 weeks before the last frost date gives you a significant head start.
