For an earlier harvest, sow seeds in mid to late April to give them time to establish indoors for better growth.
Later in May, begin hardening off your indoor-raised plants to slowly introduce them to the outdoor conditions.
You can do this by moving the plants outdoors during the day, then bring them in at night for one week.
The following week, leave in a sheltered spot outdoors all day and night before planting them out in the early signs of summer (June) to thrive outdoors.
