Succulents are among some of the easiest plants to grow. They are often recommended for novice gardeners and thrive during lengthy vacations with no intervention. However, one of the most common causes of plant illness (and even death) is rotting succulent roots.
Succulents native to arid regions must have adequate drainage and moderate watering for good root rot control.
Why Do Succulents Rot?
Limp, shriveled, and yellow leaves are an indicator that
succulent roots are rotting. Why do succulents rot? The answer can be cultural
or fungal. In most cases, it is an issue brought upon by poor
draining soil and too
much moisture. Learning how to stop succulent rot is important to save your
plant.
Many succulents are native to arid desert regions, although
a few, such as the holiday
cacti, are suited to warm, tropical areas. Any plant that is potted and has
little drainage along with being in heavy soil can fall prey to root rot. Container
plants are a special risk, as they must have all their needs met in a small
area.
The most common signs outside of leaf problems are a soft,
overly flexible stem where the plant has trouble supporting itself. The plant
or the soil may also have an odor. Soil will smell like mildew or the plant
will simply smell like rot. Plants begin caving in at the main body. The
collapse of plant tissue is a later and dangerous sign that a succulent’s roots
are rotting.
Preventing Rotting Succulent Roots
Succulent root rot control starts with early planting and
care. Use a well-draining succulent soil or make
your own with a mixture of potting soil, sand, and peat. It may be best to
fumigate or sterilize
the soil prior to planting to kill any existing insect larvae, fungus, or
bacteria.
Water only when the bottom of the soil at the drainage holes
feels dry. Reduce watering by half in winter. If you see any signs of rot,
certain succulents can be saved with an application of copper
fungicide, either as a soil drench or as a foliar application.
How to Stop Succulent Root Rot
If you are a very vigilant grower and notice signs early,
there are steps you can take to save your plant if the succulent roots are
rotting. Many succulents produce offsets that can be divided away from a parent
plant, allowed to callus, and replanted.
If the base of the main plant is strong and the roots appear
to be disease free, you can still save the entire plant. Remove it from the
diseased soil and cut off any rotted roots or leaves with sterile, sharp
instruments.
Next, sterilize the container and use fresh soil. Mix a bowl of water with a drop of anti-bacterial dish soap. Using fresh cotton swabs, wipe the roots of the succulent very carefully. You could also dunk the roots into a diluted anti-fungal preparation. Let the roots dry completely before repotting. Allow the plant to stay dry for two weeks and observe it closely.
Even if you can’t preserve the whole plant, leaves, stems,
or offsets may be taken to start a new one.
