The Q&A Archives: Fungus

Question: I'm told we have a fungus in our garden soil. The leaves get spots, turn yellow and then dry up. It is especially bad with tomatoes. The plant dies from the bottom up. We have moved them from one area to another but it happened again this year. Was also true of our garden in another state.

Answer: If you continually have problems with your tomatoes, you'll want to be careful when you purchase seeds or plants; look for varieties that are disease resistant. VFN indicates the tomato variety is resistant to three types of diseases; Verticilum wilt, Fusarium wilt and nematodes. Many of the new hybrid varieties are VFN types. After planting, use an organic mulch over the soil so water does not splash from the soil onto your plants. This will prevent any soilborne fungus from affecting your plants. One more step you can take to keep your plants healthy is to remember to apply water to the soil, not to the leaves and stems of the plants when you water.

Best wishes with your garden.
