This video answers some questions on how to identify some of the problems that occur in vegetable gardens: for example, if there are missing leaves on your tomato plant, then it is an indication that they are being eaten by something. In some cases, this pest is the Tomato Hornworm. The Mosaic Virus and Curly Top and Tomato Spotted Wilt also attacks tomato plants. Tobacco Mosaic Virus can be caused by smokers, who smoke too close to your garden. Chile Wilt is a problem in monsoon season, when there is too much moisture in the soil. Root Rot may also be a problem. This can be seen, when you pull a plant out of the garden.
