Yellow Morning Glory Problems:
Morning glories are not only beautiful flowers but they have been used in traditional medicine for centuries. They were used as a tonic to treat fever, cough, diarrhea, stomach aches and many other ailments.
Today there are several types of morning glory plants grown worldwide. Some varieties are called “golden” or “silver”. These varieties grow in warmer climates while others grow in colder regions like Canada and Russia. The main difference between these two kinds of morning glory is their color.
The most common type of morning glory (Orobanche spp.) grows in warm areas such as Florida, Texas, California and Mexico.
They grow to about 3 feet tall with a round shape and white flowers. They produce small red berries which are eaten raw or cooked. They are very nutritious and contain vitamins A, C, E and K1. They are also rich in vitamin B6 and potassium.
Other varieties of morning glory (Asclepias spp.) grow in cooler climates such as Idaho, Oregon, Washington state and Russia.
They grow to about 2 feet tall with a rounded shape and yellow flowers. Their berries taste bitter when eaten raw but they provide good nutrition when cooked. They are rich in calcium, iron, magnesium, manganese and zinc.
One of the biggest problems with morning glories is a disease called “fungus”. The fungus can cause the plant’s leaves to shrivel up, turn brown and die.
This can kill the entire plant if it spreads to all the leaves.
Other diseases that attack the leaves include anthracnose and powdery mildew. Both of these are caused by fungi and can spread quickly in humid weather or wet conditions.
They cause the leaves to become covered in spots and eventually turn completely black and die. This can be overcome by keeping the plants healthy, but it is always good to practice preventative measures to keep fungus from spreading.
The easiest way to prevent these diseases is to water morning glories from below. This prevents moisture from building up around the base of the plant and helps keep the leaves dry.
It also prevents fungal spores in the soil from getting on the leaves which could lead to infection. Fungicides can also be added to the water when watering the plants.
Insects such as aphids, caterpillars and thrips feed on morning glory plants and can leave small holes in the leaves which can allow light in. This prevents the plant from getting the light it needs and causes the leaves to turn yellow and die.
To prevent these problems, you should make sure there are no weeds around the base of the plant since insects like to hide in them.
