Pests and various insects will love to snack on your tomatoes. Some of the most common pests you should expect are leaf miners, flea beetles, whiteflies, and slugs. You may want to use organic pest control in order to catch these pests before they end up damaging your plants. Using organic pest control won’t compromise your tomato fruits as well. On the other hand, blight, fusarium wilt, and verticillium are also common diseases that can be caught by your tomato plants. In order to avoid the spread of such diseases, make sure not to splash water on your plant’s leaves.
