These do come on sale every year and my store runs out of them. Maybe it is too early for some as I live in the South. I had a lot of luck planting in them. I tried cherry tomatoes 2 plants per bed, another with 2 peppers and few herbs and zucchini 1plant, maybe you could do more. Make sure you follow directions.
