Let the plant go to seed, then take the seed heads at the end of summer and toss them about so they will be there ready and waiting next year. Here are some suggestions for self-seeding plants to try:
HERBS: Basil, chamomile, cilantro, cutting celery, dill, parsley.
VEGETABLES: Amaranth, rocket, beet, broccoli, carrot, collards, kale, lettuce, mustard, spinach, parsnip, pumpkin, radish, tomato, turnip, winter squash.
