Common Pests and Diseases
One of the most common pests that affect Asparagus Spinescens Steud. ex Roem. & Schult. is the spider mite.

As for diseases, Asparagus Spinescens Steud. ex Roem. & Schult. is prone to fungal infections such as root rot and leaf spot, both of which can be fatal to the plant if left unmanaged.
Pest Management
When it comes to pest management, the best approach is prevention. Regularly inspect your plants for signs of pest infestation, especially on the undersides of the leaves where spider mites and scale insects tend to hide. If you do find pests, the use of insecticidal soap or neem oil can be an effective solution. Be sure to follow the instructions on the product label and test on a small portion of the plant before applying it to the entire plant.
Disease Management
The key to disease management is early detection. If you notice any signs of fungal infection, such as yellowing or spotting on the leaves, it's best to remove the affected leaves immediately. Avoid overwatering your plant, as damp soil can contribute to the development of root rot. If root rot is suspected, remove the plant from its pot and inspect the roots. If the roots are brown and mushy, prune away any damaged parts and repot the plant in fresh soil.
With proper care and attention, your Asparagus Spinescens Steud. ex Roem. & Schult. can remain healthy and pest-free.
