Morning glories are beautiful, fragrant flowers that wake up with the sun and add vibrant color to your garden. Morning glories are hardy plants and are normally healthy, but sometimes insects on morning glory vines harm the health of the plant. Yellow, wilting leaves are telltale signs that your plant has an insect problem.
Beach morning glories are fast-growing vine plants that produce beautiful purple or blue flowers. They thrive in coastal regions and are prized for their ability to grow in sandy conditions. However, beach morning glories are susceptible to leaf miner infestations. Leaf miners are small insects that burrow inside leaves, creating unsightly trails, blotches, or blisters on the foliage as they feed. If untreated, leaf miners can seriously damage beach morning glory plants, impacting their growth and ability to flower. Below are some effective organic and natural methods for getting rid of leaf miners on beach morning glory plants.
Identifying Leaf Miner Infestation
The first step is learning how to identify leaf miner damage on beach morning glories Watch for these signs
- Squiggly white trails or tunnels on leaves
- Blotchy brown spots or blisters on leaves
- Curling, dried leaves
- Presence of tiny black fly specks on underside of leaves
Leaf miners start out as eggs laid on the leaves. When the eggs hatch, the larvae burrow into the leaf tissue to feed, creating the characteristic winding trails. Carefully inspect leaves to detect infestations early before major damage occurs.
Remove Infested Leaves
One of the simplest organic control methods is to manually remove leaves showing clear signs of leaf miner trails. Prune these leaves off at the base of the stem. Discard the infested leaves – do not compost them. Eliminating the infected foliage can help reduce spread of leaf miners to the rest of the plant. Check daily and remove any new infested leaves promptly.
Use Row Covers
Row covers made from lightweight fabric like cheesecloth are a physical barrier that prevents adult leaf miner flies from reaching beach morning glory plants to lay eggs. Apply row covers at the beginning of the growing season before pests arrive. Make sure to securely anchor the fabric and leave enough slack for plant growth underneath. Row covers allow sunlight air and water to penetrate to the vines.
Attract Beneficial Insects
Natural predators like ladybugs, lacewings and parasitic wasps can be used for biological control of leaf miners. Introduce them early in season to feed on eggs and larvae. You can also plant flowers near the morning glories to attract beneficial insects. Marigolds, dill and cosmos are good choices. The predator insects will help keep leaf miner populations down.
Apply Neem Oil
Neem oil is an organic pesticide that can be sprayed on beach morning glories to kill leaf miner larvae. It is safe for people, pets and beneficial insects. Mix neem oil with water according to label directions. Apply it thoroughly to leaf tops and undersides, as leaf miners lay their eggs on undersides. Reapply every 7-10 days to disrupt the leaf miner life cycle. Neem oil is most effective on young larvae.
Use Insecticidal Soap
Insecticidal soap sprayed on plants can help eliminate leaf miner infestations. It works by penetrating the waxy cuticle of insect bodies, causing dehydration and death. Mix 2-3 tablespoons of insecticidal soap with 1 quart water and spray all leaf surfaces, especially undersides of leaves. Reapply every 5-7 days until miners are gone. Be sure to use a soap designed for gardens/plants, not household soap.
Apply Kaolin Clay
Kaolin clay is a natural mineral substance that can control leaf miners when sprayed on plants. The fine powder coats leaves with a grainy white film that deters female flies from laying eggs. It also irritates larvae, reducing feeding. Mix kaolin clay with water per label instructions and spray leaves, tops and bottoms, until fully coated. Reapply after rain. Kaolin clay has no toxins and won’t harm plants.
Use Floating Row Covers
For a chemical-free preventive approach, drape lightweight spun polyester fabric over plants as floating row covers. The sheer material allows air and light in but forms a protective barrier to keep adult leaf miners away. Apply covers at start of season and remove when plants begin flowering so pollinators can access blooms. Secure edges of fabric with rocks, boards, or landscape pins.
Maintain Plant Health
Keeping beach morning glories healthy and vigorous helps deter leaf miners. Water adequately, fertilize monthly, remove weeds/debris, and promptly treat any disease issues. Healthy plants can better withstand and outgrow leaf miner damage. But avoid over-fertilizing, which can make plants more attractive to leaf miners.
Monitor Regularly
Inspect beach morning glories thoroughly each day if leaf miners have been a problem. Check undersides of leaves closely for eggs and small winding trails indicating new infestations. Catching leaf miners early is key before they multiply and spread extensively through your vines. Be prepared to take quick action at first signs.
As a last resort, use natural sprays like neem oil, insecticidal soap or kaolin clay. Avoid chemical insecticides which can harm pollinators and other beneficial insects in your garden. With persistence using multiple organic methods, you can get rid of destructive leaf miners and keep your beach morning glories thriving.
Morning Glory Pest Control
A successful way to rid your morning glory of aphids and spider mites is by syringing. Syringing will knock the pests from your plants by using a hard stream of water. To keep these insects under control, it is best if you repeat this process two times a week. Insecticidal soap and horticultural oils are also used in controlling pests. Both the soap and oil must make contact with the insects for them to be effective. You can also choose from natural pest controls or organic fungicides, like neem oil. You can also pluck the pests off with tweezers and drop them in soapy water. Doing this is the most environmentally safe way of ridding your morning glory of these pests. No matter which method you choose, be sure to be consistent and persistent as the health of your plant depends on your diligence.
Morning Glory Pest Problems
There are two common types of insect pests affecting morning glories; both are sucking pests. One is the cotton aphid and the other sucking pest is a spider mite. Cotton aphids come in many colors. They like to attack the morning glory in the morning. They are difficult to see, but if you look closely, you will observe a mass of aphids on a leaf that is yellowed and crinkling. The spider mite sucks the sap from the underside of the leaf with its sharp mouth. By the time spider mites are detected, a considerable amount of damage will have been sustained by the morning glory. There are also insects that like to eat through the leaves and stems of the morning glory. The leaf miner drills tunnels into the leaves of the plant. A green caterpillar called a leafcutter feeds at night and severs the stem of the morning glory and a golden tortoise beetle makes small to medium holes in the foliage. If your morning glory plant is not treated for pests, they will eventually attack the vine. Pests of morning glory vine need to be eradicated as soon as you see them or evidence of their presence.

How do you keep leaf miners at bay?
Keeping leaf miners at bay starts with proactive tactics and fostering plant strength. Employing physical barriers, such as floating row covers, and nurturing robust plants through proper soil management are essential. Growing strong plants begins with selecting resilient varieties and creating an environment conducive to their health.
How do you grow beach morning glories?
To establish beach morning glories in gardens, take a cutting and set it into moistened sand. The internodes will shortly send out roots. Set them 3 feet (1 m.) apart and keep plants moist for the first few months. Gardeners growing beach morning glories can breathe a sigh of relief.
