Many take great enjoyment in growing tomatoes in their home garden. There is something special about growing tomato plants and reaping the benefits of eating a fresh, home-grown tomato.
Unfortunately, many home gardeners run into disease problems when growing tomatoes. Once a tomato plant shows symptoms of tomato problems like verticillium wilt, fusarium wilt, nematodes, and other diseases; there is not much that can be done. However, there are some things that you can do before you start growing tomatoes that will help reduce tomato diseases from occurring.
There are many tomato varieties out there to pick from. There is not one perfect variety of tomato for the home garden. Picking a variety to grow is based more on personal preference. Many home gardeners that have grown different varieties every year have learned what varieties provide the type and taste of tomato they prefer.
Even though there are a lot of tomato varieties to select from, there are some things to think about and look for when selecting varieties. Selecting tomato varieties with disease resistance will help in reducing some disease problems that are often dealt with when growing tomatoes. Resistance to a disease does not necessarily mean that the variety will be completely immune, but a resistant variety will help at least reduce the severity of the disease.
Tomato varieties have abbreviations included on the plant label or variety description. Each letter or abbreviation represents what disease the variety is resistant to. Here are abbreviations of the most common diseases:
When selecting varieties, you would want to look for resistance to diseases that you have had problems with in the past. For example, if you had problems with tomatoes getting one of the wilt diseases, select varieties that have a V and/or F. If trying to remember what abbreviation goes with which tomato disease is too much trouble, at least remember that the more abbreviations or letters that are with a variety the better luck you will have in dealing with past disease problems.
Along with selecting disease resistant varieties, remember to not plant your tomato plants in the same spot that you did last year. If you encountered disease problems in the past years and continue to plant tomatoes in the same spot, diseases will build-up in the soil year after year which will only escalate the problems each year. If you have had a history of tomato disease problem in the area that you plant tomatoes and have nowhere else to plant the tomatoes, consider planting tomatoes in containers. Planting in containers will eliminate the risk of planting tomatoes in soils with soil-borne diseases.
