Changing soil in Earth Boxes & Raised Beds??
How often do you change the soil in your earth boxes and raised beds?
I use peat moss, pine bark, perlite, vermiculite and compost in my raised beds and plant tomatoes year after year in the beds, when should the soil be changed to avoid problems like RKN?
I use peat moss, perlite and vermiculite in my earth boxes, does anyone change the soil in their earth boxes, if so how often? Has anyone ever had RKN or other pests/diseases in their earth box because of growing tomatoes year after year?
