What is Root Rot?

Root rot is a common succulent disease. It is a fungal infection that kills succulent plant tissue.

The fungus damages the succulent’s roots and prevents them from performing their essential functions.

Succulent root rot will likely kill succulents if it’s not treated.

Many kinds of fungus can cause succulent root rot, including Rhizoctonia, Phytophthora, Pythium, and Fusarium.

Succulents are prone to root rot because they have a waxy coating on the inside of their leaves and stems.

This makes it harder for water to get out, which means that succulents are more likely to retain moisture in humid environments.

What Causes Root Rot in Succulents

The best way to understand what causes succulent root rot is by understanding how the disease progresses.

Succulents have very fine roots which often intertwine around one another, creating a dense mat on top of the soil surface where they grow – this makes them prone to infection from all kinds of fungi lurking in soils.

Root rot succulent diseases are caused by fungi that thrive in moist conditions, which is why succulents are so susceptible.

Once the soil becomes too damp, these parasites become active and will start to cause damage quickly.

Because succulent roots are so intertwined, it doesn’t take much to cause them significant problems.

The main causes of succulent root rot are:

Overwatering Succulents

Overwatering succulent plants is the most common reason for succulents to develop root rot.

While succulents are very hardy, they still need proper drainage and regular watering schedules.

If you overwater your plant or give it too much water at one time, its roots will not absorb all of the excess moisture, which causes problems later on.

Improper Drainage

Succulents should always be planted in well-drained soil so that their roots do not stay wet for long periods after watering.

This can cause fungi like pythium and phytophthora to attack the roots resulting in root rot succulent diseases.

This means planting succulents in a cactus/succulent potting mix or succulent soil with added perlite to increase drainage.

Stagnant Water on Succulents Leaves

When succulents are watered, the water droplets form on their leaves and then roll-off.

If that water is not being absorbed or evaporated quickly enough due to humidity or lack of airflow, it can create a breeding ground for harmful fungi, which will result in succulent root rot diseases if left untreated.

This also makes succulents more susceptible during rainy seasons when there isn’t much evaporation occurring naturally because of high humidity levels combined with moist soil already present from previous rainfall events. 

Root Damage

When succulent roots are damaged, it makes them more susceptible to succulent root rot diseases.

This can be caused by physical damage such as improper pruning or moving/storing succulents when their soil is wet.

It can also be caused by chemical damage like applying strong fertilizers directly onto succulents without testing the strength of the fertilizer first (it may burn the plant).

Old Age

Succulents will start to develop succulent root rot diseases as they get older, just like any other plant.

As succulent plants grow and produce leaves, new roots are produced, too, which allows them to absorb more moisture from the soil than younger succulents with smaller root systems can.

This means succulents need to be repotted more often as they get older so that their soil does not stay wet for too long.

Root Diseases

Other succulent root diseases are caused by pathogens like nematodes, Plasmodiophora brassicae (a parasitic roundworm that infects succulents), and Pythium fungi.

These succulent root rot diseases can all come from infected succulents or other plants in your garden.

It is essential to properly sterilize any tools you use when working with succulents to prevent succulent root rot disease transmission between succulents you want to keep healthy.

If succulents have root rot, it may be difficult to tell if the lighter color is due to discoloration or simply because your succulent stems are turning a light green where they meet their soil.

Rotting Succulent Plant Stems

Root rot can also cause succulents’ stems to begin rotting away where they meet the soil under your succulent plants.

This succulent problem is especially common in succulents with fleshy succulent leaves like some varieties of jade plant succulents.
