Sorry if you got this twice...but looking for as many answers as I can... I've heard, and seen, that planting tomatoes or peppers over and over again in the same area eventually makes that bed unuseable for planting tomatoes or peppers again in that soil after a few years. So my questions are, what exactly does it 1. take out or 2. put in that makes the soil bad, and what would be an addenda to the soil to lengthen or re-nourish it? I do try to roatate the crops around but next year is gonna be hard because most of my beds have peppers and tomatoes in them (goin for salsa! and sauces!), and I want to be able to plant peppers and tomatoes next year as well! So short of depriving myself of an abundant harvest of my favorite veggies next year, what is an alternative? Additionally I have three beds that are the most suited for both tomatoes and peppers because they get the most sun and heat. So I would probably want to use them yearly for those crops. TIA
