2).Trim the plant. Cut off any dead, insect-eaten, rotting or discolored sections of the plant. If most of the plant is affected, dispose of it away from other plants and find another planting material.
If using a sucker, remove all but a few centimeters (1–2 inches) of the roots. This will limit the chance of disease. You can also remove any leaves in excess of five and/or cut the top of the plant off with a slanting cut to increase the amount of sunlight that warms the soil for root growth and rot prevention.
