One of the main diseases that can affect your tomato crop is blight. There are several types of blight that can strike tomatoes, and this short video shares some important tips for preventing tomato blight in your organic garden.
Tomato blight can strike early or late in the season, and can cause yellowed, browned, blackened, or splotched leaves. Early blight can even kill tomato plants before they’ve had a chance to bear a crop.
If it’s late in the season, and the crop is already nearly done, you may not be too concerned about blight, but if you plan properly, and early enough, you can often avoid it altogether with these simple tips:
1. Choose Disease Resistant Varieties When Buying or Planting Tomatoes.
2. Use Ground Cover Such As Newspaper and Mulch Around Your Tomato Plants.
3. Keep Plants Elevated For Air Flow Using Stakes or Cages.
4: Remove Infected Leaves As Soon As You See Them.
If you still have blight after following these tips, you may try spraying with Liquid Copper, an organically-approved spray that can help get rid of blight.
