Morning glories are perennials with funnel shaped, fragrant flowers that grow from a vine and come in many bright colors such as blue, pink, purple and white. These beautiful flowers open at the first sunlight and last throughout the day. These typically hardy vines, however, can sometimes suffer problems.

Morning Glory Problems

Problems with morning glories can vary but may include environmental issues and fungal diseases of morning glory.

Environmental problems with morning glories

When the leaves of a morning glory turn yellow, it is usually a sign that something is not right with your plant. Insufficient sunlight can be a cause of yellowing leaves, as morning glories require full sun to flourish. To remedy this, you can transplant your morning glory to a sunnier spot in the garden or trim any plants that are blocking the sun.

Another cause of yellow leaves is either under watering or over watering. Once your morning glory has been watered, let the soil dry before re-watering.

Morning glories do well in USDA plant hardiness zones 3-10, be sure that you are in one of these zones for best results.

Morning glory vine diseases

A fungal disease called rust is another culprit of yellowing leaves. To diagnose whether your plant has rust or not, look closely at the leaves. There will be powdery pustules on the backside of the leaf. They are what cause the leaf to turn yellow or even orange. To prevent this from happening, do not overhead water your morning glory and remove any infected leaves.

Canker is a disease that causes the stem of the morning glory to be sunken-in and brown. It wilts the ends of the leaves and then spreads onto the stem. It is a fungus that, if not taken care of, will affect the whole plant. If you suspect that your morning glory has this fungus, cut away the infected vine and dispose of it.

Problems with Morning Glory Pests

Morning glories can be infested with pests too such as the cotton aphid, the leaf miner, and the leafcutter. The cotton aphid likes to attack the plant in the morning. This insect ranges in color from yellow to black, and you can find them in masses on your leaves. The leaf miner does just that, it mines or bores holes into the leaves. A green caterpillar called the leafcutter severs the stalks of the leaves and causes them to wilt. This pest likes to do his damage at night.

The best way to rid your morning glory of these pests is by using an organic pest control and keeping your plant as healthy and happy as possible.

Planting Morning Glory Flowers

Laura goes on to say that “the difficulty in controlling the unintentional spread of these vines is the primary reason I don’t grow morning glory. Weeds and weeding are my least favorite aspects of gardening. I don’t want to plant annuals which vigorously return every year, especially since it can take years to eradicate unwanted morning glories from the garden. I feel there are so many more flowers with positive attributes I can choose for my garden.”

On the other hand, Mary Ellen feels there are many benefits of morning glory vines, not least of which is the sense of magic they bring to a flower garden. “Perfect for a trellis, fence, back deck or patio, or even to beautify a mailbox, these lovely vines will grow nearly anywhere and add a touch of color and whimsy.”

With such strong feelings for and against the planting of morning glories, it can only be left up to the individual gardener to decide whether or not these flowers are worth it in the end. Our recommendation is to thoroughly research the morning glory plants beforehand to ensure what you are actually planting is, indeed, an annual morning glory species and that you’re willing to put in the extra maintenance that may be required in keeping it manageable.

Moisture and Root Rot

Purple glory bush grows best in moist but well-drained soil. Avoid planting it in poorly drained soil, or in areas where the ground becomes wet and waterlogged after rain. Poor drainage can lead to root rot, which can eventually kill the plant. Once root rot takes hold, little can be done other than transplanting glory bush to a new site with better drainage. Stressed plants do not always survive this transition, so choosing a good site from the beginning is important.

Glory, Morning, Noon, and Night

Morning glories offer plenty of variety to choose from, and you’re just about guaranteed to find one with the colors and traits you are looking for. Their easy-to-grow quality is yet another bonus.
