What Plants are Appropriate to Sow in April?

Q: I’d like to get an early start on my garden this year. What plants are appropriate to sow in April?

A: Unless you experience a very mild spring, planting outdoors in April can be risky because the temperatures may not be high enough to ensure the seeds germinate. It may be wiser to sow just a few seeds in pots and keep them indoors (on a windowsill or in a heated greenhouse) to start them, then plant them outside as the weather warms up. For sowing indoors in April, you can plant broccoli, cabbages, celery, peppers, cucumbers, corn, eggplants, tomatoes, runner beans and kale.
