RE: 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. WHAT YOU DESCRIBE IS THE TYPICAL RESULT OF "CHEMICAL" GARDENING. EVER HEARD OF FARMLAND THAT'S USELESS, AND SAID TO BE "FARMED OUT"? USING SOLUBLE CHEMICAL FERTILIZERS AND PESTICIDES WILL EVENTUALLY FILL YOUR SOIL WITH THE SALTS OF THOSE FERTILIZERS, AND IN COMBINATION WITH TOXIC PESTICIDES WILL RENDER THE SOIL STERILE OF BENEFICIALS LIKE EARTHWORMS AND MICROBES THAT PARTICITATE IN FEEDING YOUR PLANTS. IF YOU'RE USING ORGANIC COMPOST, HUMUS, SUGAR (BEST AS DRY MOLASSES), LIQUID FISH & SEAWEED AND START WITH GOOD SOIL, IT WILL PRODUCE FOREVER. IF INTERESTED IN MORE INFORMATION ON ORGANIC METHODS, EMAIL ME PRIVATELY. TOM
