Damaged Begonias


Begonias require a growing temperature range between 60 degrees and 85 degrees. The evergreen flowering perennial succulent demands a moderate amount of humidity and partial shade or indirect sun exposure. There are over 1,000 species of begonias, according to Encyclopedia Britannica. Gardeners may face disappointment when they discover damaged begonias in their collection of household plants.


Infections, diseases and pests on damaged begonias can spread to other household plants. Identifying and controlling the problems that caused the damage is significant to prevent further damage, loss of the begonia and potential loss of other houseplants in the nearby vicinity.


Begonias are primarily a tropical plant. Imagine the climate and conditions of the tropics when you select the location to grow and display them as houseplants. Higher levels of humidity and good air flow build begonia plants' resistance to damaging diseases.

Pest Infestation

Pest infestation results in damaged begonias. Begonias are not favored only by plant collectors, but also by pests such as aphids, mites, slugs and mealy bugs. Commercial or homemade pesticides reduce the begonia damage by killing the vermin. Begonias with pest problems usually have leaf or bloom damage from pests eating the leaves, stems and blooms.

Fungus Damage

Fungus problems can also damage begonias. The most noticeable damage is often to the leaves. Leaves display fungus growth spots, wilt or completely die. Fungicides and removal of damaged plant parts fixes fungus problems. Good soil drainage and air circulation reduces the potential for fungus problems such as leaf spot and various types of blight.

Root Rot

Begonias wilt, turn yellow and die from root rot. Root rot damage is severe and difficult to repair. Over-watering happens accidentally when growers add a small amount of water daily to meet the medium humidity requirements of the plant. The water builds up in the lower portions of the soil, leaving the roots wet and susceptible to root rot. Allow begonias to dry completely between watering. Addition of extra drainage holes or the use of clay pots helps deter root rot and damaged begonias.
