What to plant now in Jersey City

Spring: Start planting cool-season crops like peas, lettuce, and spinach as early as late March. By the time of the last frost on April 1, these plants can thrive in the cooler temperatures.
Summer: As the risk of frost has passed, it's ideal to plant warm-season vegetables such as tomatoes, peppers, and cucumbers from mid-May onwards, taking full advantage of the sunlight and warm temperatures.
Fall: During late summer and into early fall, consider planting fall crops like kale and broccoli, as they can be sown around mid-August, growing until the first expected frost of November 15.
Winter: Although it's colder, November is the time for winter preparation. Consider planting cover crops like clover or rye to protect your soil and improve fertility for next spring. Snow cover can also be beneficial during this time.
