The diversity of the begonia clan make it difficult to decide on a begonia plant (Begonia spp.) From a lineup. Foliage varies among species in color, shape, texture and edging. Some cultivars’ leaves resemble spiraled seashells while others look like velvet. The flowers, too, come in all sizes and shapes, such as single or clustered, dainty or pendulous. If a fungus mars your begonia, it doesn’t necessarily indicate the plant’s demise. It is most likely botrytis, a fungal disease that attacks the flowers first. However, powdery mildew can also be a possibility. Fortunately, you can see to the fungus efficiently even without an specific diagnosis.
Prune off all dead or dying tissue in the begonias, such as contaminated flowers, leaves and stems. Clean the pruners involving clips with denatured alcohol. Meticulously get rid of every piece of fallen blossom and foliage.
Move the plant outside in the event that you have been growing it indoors. High humidity and stagnant air encourage fungus; great air circulation prevents and sometimes eliminates it. Catch several feet between container plants outside and avoid watering the plants out from above.
Mix an appropriate fungicide with water on your sprayer in accordance with label directions. To ensure complete coverage, spray both sides of every leaf, the blossom and the stem.
Repeat if necessary until the fungus is removed. Most fungicides give a range of time for reapplication, often at one- to two-week periods. If it rains a lot following the first program or if the plant offers fresh development, repeat spray at the shorter interval.
