The desert rose is a succulent plant that can be treated as a bonsai due to its large caudex and branching characteristics. The desert rose is an excellent alternative for bonsai fans who lack the patience to establish a bonsai tree.
Adenium Stem Rot
A fungus causes the stem root of the desert rose plant. It's the most prevalent adenium issue. Adenium rot can be black, dark brown, or yellow in color.
The genuine desert rose rot can be moist or dry, and it works its way down the adenium's stem. When we see this, we don't wait for the plant to solve the problem; instead, we take off the plant's most effective area. Make sure you look inside the stem while cutting off the stem and that the adenium plant cut is far enough down that you only see excellent tissue with discoloration.
After cutting off the infected area, make sure to apply fungicide to avoid any other infections. Adenium stem rot can be easily identified by checking it's leaves. When the leaves on the tip of the adenium start to fall off and turn brown, this is a solid symptom of stem rot.
Another way to find rotting is, sudden growth of new shoots in the plant. This may because, water stored in the caudex creates an internal pressure within the plant as the water can't travel from root to plant tip. If you see this sudden growth of new shoots, check the plant stem. If you see any black dots in the stem, it's a clear indication of stem rot.
Adenium Root Rot
Root rot is a prevalent problem with desert roses, and it's probably the most common reason for people losing this lovely plant.
When the caudex retains too much water, it causes root rot in desert roses. Pimples on the caudex that feel soft when lightly squeezed are an early indication. Yellowing leaves caused by fungal stem rot can extend to branches and roots, resulting in fungal root rot. The solution is to remove unhealthy roots.
To fix Desert Rose root rot, remove the plant from the potting soil cautiously and search for soft roots and delicate stems. Wash out the tainted region with the assistance of quick running water however much as could reasonably be expected. Take a sanitized blade and remove all the soft (brown) part, apply fungicide and let the plant dry out prior to repotting it.
Once your plant have healed and everything looks more stable now, you can replant them into the soil. Using rooting hormone promote the growth of new roots.
