What to plant now in Erie

In early spring, from late March to late April, plant cool-season crops like peas and lettuce. Ensure you have your seeds in the ground before the last frost date of April 29 for a successful harvest.
During the late spring to early summer, from late May to early June, is the perfect time to plant warm-season crops like tomatoes and peppers after the risk of frost has passed. Be sure to transplant seedlings once the soil has warmed sufficiently.
As summer transitions to fall, late July to early August is ideal for sowing fast-maturing crops such as radishes and kale. These crops can take advantage of the cooler temperatures while still ensuring maturity before the fall frost.
In fall, from September to early October, it's crucial to harvest your remaining crops and plant overwintering varieties, like garlic. With the first frost date on October 28, prepare your garden for winter and protect any remaining tender crops.

In Erie (182 frost-free days, a long season), 30 of 56 planner crops fit outright, 25 get two plantings, 1 crop is perennial.
