Check these first
- Feel the soil moisture level two inches deep.
- Inspect the base of the stem for dark or mushy tissue.
- Check that the pot has adequate drainage holes.
Likely causes
Poor drainage
Most likelyHow to tell: The soil stays soggy for days after watering and the base of the stem feels soft or mushy.
What to do: Improve soil drainage by mixing in grit or sand. If the plant is in a pot, ensure it has large drainage holes and use a fast draining cactus mix.
Overwatering
Most likelyHow to tell: Leaves turn yellow and drop while the soil remains constantly wet.
What to do: Wait until the top 3 inches of soil are completely dry before watering again. Reduce your watering frequency to every 14 days during cooler months.
When to worry
If the stem base is black and mushy, the plant is likely beyond saving. It is normal for the plant to look slightly thirsty in extreme heat.

Questions people ask
- Can I save a plant with root rot?
- If the rot is caught early, you can try repotting into fresh dry soil and trimming away black, mushy roots. If the main stem is affected, it is usually too late.
- How often should I water my Cistus?
- Once established, water every 7 to 14 days. Always let the soil dry out significantly between waterings.
