Peach trees can provide a wealth of benefits--delicious fruit and shade are just a couple of them. However, when your peach tree is attacked by leaf curl, you must act quickly to save it for future harvests and enjoyment. Peach leaf curl is a fungal disease that causes the leaves to grow warty and develop a red hue. When it comes to dealing with the disease, preventing it yearly is the best option. If the tree is already infected, there are a couple things you can do to prevent it from spreading.
Purchase a fungicide from your local gardening store. Make sure it has a fixed copper product.
Read the manufacturer's directions on the fungicide thoroughly to ensure that you prepare it properly. Usually the standard mix ratio is about 4 tbsp. of fungicide per 1 gallon of water in a large bucket. Keep in mind that different brands of peach leaf curl fungicide require different measurements and application times. (For example, some require application in spring, others in the fall).
Start around the bottom of the tree trunk and thoroughly cover the fungicide all over the bark, branches and foliage. Work from the ground up and pay close attention to covering all areas of the tree.
Let the fungicide dry before touching the tree. Reapply the fungicide if it rains within a week.
Sanitize pruning shears in a mixture of 30 percent water and 70 percent rubbing alcohol in order to prune off the diseased branches of the peach tree.
Set the pruning shears at a downward angle on the branch and cut off at the base where it connects at the trunk.
Prevent future peach leaf curl by applying copper fungicide to the tree.
