Oh this is the first time I have heard about the disease thing. All I have ever read was rotate such and such crop with such and such because of nutrient imbalance. That's it! Thank the lord I have you guys on here to ask questions to! I never even figured out what rotation meant entirely until ChickensAreSweet answered. I might have a college degree but I need to have things flat out explained to me sometimes! Thank you guys for answering my questions. Hopefully someday I will have a beautiful garden.You should rotate your plants every couple of years at the least. There are a couple of reasons that this is suggested.
1.) If you plant the same thing every year in the same place, eventually the soil will become deficient in the nutrients that that specific plant uses and needs to perform best. For example, tomatoes use more potasium and less phosphorous; while a cucumber needs more phosphorous and less potasium for a good crop. By rotating the crops every couple of yeasr, you can keep the nutrient levels form building up too high or getting too low.
more importantly though:
2.) By planting a different plant in a spot, you will break the disease/pest cycle for that soil. If you plant tomatoes every year in the same spot, you will have a build up of the virus/bacterium in the soil that cause tomato diseases. And the pests lay eggs in the soil, so in the spring, right off the get-go, you will have insect pests eating your seedlings. If you plant carrots in that spot the next year, then the tomato diseases don't have a host to live on and will die off. Planting the same plant year-after year-after year the diseases and pests will really build up in the soil until the plants cannot survive without massive doses of chemicals to treat those problems.
I still want to know where ChickensAreSweet keeps the poo for a year
