Stonecrop - diseases and pests
Actually, the stonecrop is a very robust plant that is not susceptible to disease or pest infestation, although of course this is not entirely immune to such afflictions. In particular, in the case of unsuitable locations and / or improper care, damage can occur or the stonecrop (as the fat hen sometimes is also called) loses its resistance.
Moisture and root rot
Especially with regard to waterlogging the stonecrop is very sensitive; This leads to root rot and over time to the death of the entire plant. In this case, the root area is attacked by a rot-causing Phytophthora fungus. You can identify an infestation by symptoms like this:
What helps against root rot?
In terms of root rot, prevention is best, which means you should avoid waterlogging. This is done by sufficient drainage both in the garden soil and in potted crops, such as by loosening the substrate with sand or gravel. In the case of a mild or incipient infestation, the plant can sometimes be rescued by digging it out, cutting away the affected areas and moving the thus adjusted fawn to another, more suitable (perhaps repaired with sand) location. In case of heavy infestation, the plant should be disposed of with household waste.
Danger by the weeping weevil
Also the weeping weevil, a mostly dark colored weevil, as well as its larvae can cause considerable damage with fat hens. While the larvae do well at the roots, the meaty leaves taste the adult animal above all. There the weeping weevil also leaves the typical food marks. In the event of an infestation, you can take the following countermeasures:
Especially the biological control by nematodes is very successful, whereby you should use the parasites if possible between April and May as well as from August to September - at these times the chances of success are highest.
Tips
In addition, the fat hen can also be affected by mildew. The typical white mushroom turf on the upper side of the leaves characterizes the powdery mildew, also known as "fair weather mushroom", which occurs especially in heat and drought.
