Gardening can be therapeutic, especially in the summer when the heat brings so much life to your garden. Unfortunately, some of our plants are prone to developing blight, an infection caused by various species of fungi, bacteria or viruses. Now that it’s the right time of year for growing and maintaining your garden, it’s important to know how to handle blight so you can manage the issue before it causes serious damage. Here is a guide to dealing with blight in your garden.

Identifying Blight

The first step to dealing with blight is recognizing it. Blight usually appears on the leaves or stems of your plants in the form of dark spots, discolored areas, wilt, fewer flowers than usual or wilting and discoloration of a plant’s leaves or stems. Blight can also cause deformities and lesions to your plant's growth.

Managing Blight

Once you’ve identified the blight, you’ll want to take quick action to manage the issue. First, do your best to identify the type of blight that has affected your plant. Different types of blight may need to be treated with different fungicides so it’s important to be sure what you’re dealing with. If you can’t tell what type of blight it is, you can take a sample to your local gardening center and get it tested. There are also a variety of fungicides available that can be used to manage the blight.

Preventing Blight

Prevention is key to dealing with blight, and there are a few steps you can take to help keep your garden plant-healthy. Keep your garden clean by removing dead leaves and other plant debris, as this could be harboring the blight-causing fungi. Additionally, use mulch to keep the soil moist, which can discourage the spread of blight-causing fungi. Prune your plants regularly to encourage healthy growth and air circulation, and regularly inspect your plants to identify any possible signs of blight.


Dealing with blight can be difficult but it’s important to take quick action to keep it from spreading or causing more damage. With a little preventative maintenance and regular inspections, you can keep your garden healthy and safe from blight.
