A common problem that affects many gardeners around the world is leaf curl.
Curling leaves can be a symptom of insect damage, a fungus, excess watering, or even a nutrient deficiency .
Fortunately, there are some natural remedies to help get rid of leaf curl. In this blog post, we’ll provide some tips on how to naturally control it in your garden.
Leaf Curl Disease Symptoms
It’s important to recognize the signs and symptoms of leaf curl disease, so you can identify it early and treat it quickly.
Signs of leaf curl include curling of leaves, yellowing of veins, and reddish or purple areas on leaves. Leaves affected by this disease may also become stunted and powdery gray.
Plants That it Affects
Plants commonly affected by leaf curl include peaches, tomatoes, eggplant, citrus, nectarines, squash, peppers, apricot, cherry, and plum trees.
Leaf curl is also a common problem in houseplants and can be caused by a few different things (as mentioned above).
Too little or too much water can also cause leaf curl, so you’ll want to make sure that your plant has the right balance.
With houseplants, overwatering is typically more of an issue than underwatering. Simply feel the soil with your finger, and if it’s damp, then your plant doesn’t need additional water yet.
How to Get Rid of Leaf Curl Naturally
You don’t need to turn to harsh chemicals or risky treatments to deal with leaf curl. With these strategies on hand, you’ll soon be able to reclaim your garden with healthier plants.
1. Pruning Your Plants
Make sure you are pruning your plants regularly in order to encourage healthy growth and prevent diseases from spreading from one plant to another.
Prune any leaves or stems that show signs of distress or damage caused by leaf curl. This will help reduce the number of spores that can overwinter.
2. Vinegar Solution
Vinegar is an amazing natural remedy for controlling and getting rid of peach leaf curl. It kills fungi.
To make a homemade spray for leaf curl, mix one tablespoon of white vinegar or ACV with a gallon of water. Then, spray it directly on the affected plants.
3. DIY Plant Protection Spray
You can also create a DIY natural plant protection spray with ingredients such as garlic, hot peppers, and onions. This acts as a repellent against certain pests that can cause leaf curl.
Simply blend one head of garlic, 5 hot peppers, and 3 small onions in 2 cups of water. Afterward, pour the mixture into a glass container and let it sit overnight.
To use, pour ¼ of the strained liquid into a quart bottle with water and a tablespoon of liquid soap. Shake well.
Apply the solution to your plants every day for about a week.
4. Oregano Oil
Oregano oil is another natural remedy for leaf curls. It’s a strong antifungal agent , so it can help kill off any unwanted fungi.
All you need to do is mix 6-7 ml of oregano oil with one gallon of water in a spray bottle, and then spray your trees.
5. Rake Up Fallen Leaves
As the leaves fall, they can harbor Taphrina deformans spores, which can further affect the tree. So rake up your fallen leaves and discard them.
6. Avoid Overhead Watering
Overhead watering of the leaves of your plants can cause the disease to spread due to the splashing of the water.
Therefore, when watering your plants, stick to watering at the base of the plant and away from the leaves if possible.
7. Baking Soda
You can also use baking soda as a foliar spray to help prevent fungal diseases from attacking your plants. One user (ayz) found that baking soda worked fine for treating peach leaf curl .
Simply mix 1 teaspoon of baking soda with 1 quart of water and spray it onto the plant’s leaves until they are wet.
This should help reduce any existing fungal diseases as well as provide some protection against future infections.
8. Garlic Spray
Garlic has properties that attack insects and can also fight fungal infections, so it makes sense to use it in your garden.
Making garlic spray for plants is surprisingly easy. Just follow the recipe in the linked article.
9. Neem Oil
Not only will neem oil help control the pests on your plants, but it also has antifungal properties that can help prevent further infection.
Apply this natural treatment as soon as you notice leaf curl on your plants and continue applying it as needed in order to keep the disease under control.
Just mix a tablespoon of neem oil and a teaspoon of liquid soap with a gallon of water and spray your plants.
10. Epsom Salt
Epsom salt can also help treat curly leaves on peach trees, nectarine trees, almond trees, and other fruit trees. Just apply some Epsom salt to the soil around the trees to help increase magnesium levels.
Alternatively, make a leaf curl spray by combining 2 tablespoons of Epsom salt in a gallon of water. Use the solution to spray the curled foliage.
