Powdery mildew on begonia is caused by a fungus (Erysiphe cichoracearum). The powdery patches on begonia are made of fungus strands. Air currents carry the spores, which are capable of infecting leaves, stems, and flowers of the same or other plants. The spores are carried by wind, rain, or snow and can be found on the ground or in the air.
The most common symptoms of this fungal disease are yellowing of leaves and stems and the appearance of white spots on leaves. Symptoms may also be present on flowers, buds, petioles, stamens, pistils, roots, etc. If you notice any of these symptoms on your plants, it is important to contact your local nursery or garden center for advice on how to treat the problem.

What do Overwatered begonias look like?
An overwatered begonia will have yellowing leaves, beginning at the base. Even though the plant’s location has good humidity, you may see brown leaf tips. The leaves will feel dry when they start to drop.
If the overwatering is severe, you may see the leaves turn brown and fall off. If this is the case, it is best to remove the plants from the pot and place them in a cool, dry place for a few days before re-potting.
Why are my begonia leaves losing color?
The leaf edges of begonias will turn brown and crisp if it is too hot and dry. Begonias don’t like humidity because they don’t want to sit in water or have a lot of humidity in the air. Begonia can be grown from seed or cuttings. The best way to grow begonia is to plant it in a pot and let it grow for a year or two.
This will give the plant plenty of time to get used to its surroundings and to establish a strong root system. Once it has established itself, you can cut it back to a smaller size and transplant it into a larger pot. It is important to keep the soil moist, but not so moist that it dries out the roots.
When you cut back the size of the pot, make sure you leave enough room for the new plant to spread out and grow. You can also use a soil mix that has a little bit of compost in it to help with the root development. Begonsia is a slow-growing plant, so it will take a while before you see the results you are looking for.
What does powdery mildew look like on begonias?
The disease can be seen as a white to gray powdery growth on leaves and flowers. It may not affect the plant at all, or it may cause the leaves to die. Mildew is a fungal disease that can be spread by direct contact with infected plants.
It can also spread from plant to plant through the air, soil, or water. The disease can spread to other plants in the same family as the affected plant. Symptoms of the disease are similar to those of other mildews, but the symptoms are milder and less severe.
How often should a begonia be watered?
A good rule of thumb is to water every couple of days. When it’s hot and dry, you need to water more often than when the air is cooler. Plants that are in partial shade will require more water than plants that are in full sun. Pruning is the process of removing unwanted branches from the plant.
This can be done at any time of the year, but the best time to prune is in the spring and summer. If you are pruning in late spring or early summer, be sure to remove any dead or dying branches before they become a problem for the rest of your garden.
Do begonias like sun or shade?
They do best in situations with shade or morning sun/afternoon shade. Tuberous begonias are ideal for hanging baskets and window boxes because they have flowers that hang down a little. Don’t grow them in places that don’t have good drainage to prevent root rot. Begonia are easy to care for and can be grown in a wide variety of climates. They thrive in full sun, partial shade, and full shade with little to no water.
If you live in an area that gets a lot of rain, you may want to consider growing them in pots or pots with a drainage hole in the bottom. This will help keep the soil moist and prevent the roots from drying out too much. You can also plant them directly into the ground, but be careful not to over-water them as this can cause them to rot and die.
Can begonias get too much sun?
Begonias exposed to too much sun may wilt or develop brown or yellow spots on their leaves. The blossoms may fail to bloom completely. They might lose their natural color. Most begonia species can be damaged by excessive sun exposure. If you notice any of the following symptoms, you should contact your local arborist or garden center for advice: the leaves turn yellow or brown; the flowers die; or the blooms do not bloom.
