Q: I have a small vegetable garden in which I plant tomatoes. I’m concerned about repeatedly planting tomatoes there year after year. The garden isn’t big enough to rotate plants.
A: You have a problem faced by many gardeners with a small area in which to work. I think you’ll just have to be vigilant about controlling weeds and insects so their population can’t build up. Always remove and destroy diseased leaves. Aim to provide for your tomatoes a sandy loam soil that does not remain soggy. If you are reasonably attentive to management details I think you can successfully grow tomatoes in the same spot for several years.
