Common Problems With ‘Autumn Joy’ Stonecrop

Moreover, apart from occasional pest infestations, certain diseases and care conditions pose

challenges to the cultivation of the ‘Autumn Joy’ Stonecrop.

Here are some considerations to keep in mind while growing this plant:

Leaf Drop in Plants

The presence of soil fungi, known as crown or stem rot, results in discoloration at the soil line and

eventual foliage drop as the plant succumbs.

This fungus spreads within the soil, requiring the removal of infected areas.

The foliage may exhibit reddish or brown bumps near the plant’s base.

The occurrence of dry leaves and flowers with dead spots before falling often indicates the presence

of leaf blotch.

Maintain plant health by promptly removing diseased, damaged, or yellowing leaves and branches,

ensuring good airflow, and adhering to proper care practices.

Yellowing Leaves

Yellow spots on leaves could signal an aphid infestation.

Aphids, while feeding on foliage, leave sap and create small holes across the plant.

They extract nutrients and harm plant tissue by injecting toxins into the leaves.

Resolving most aphid problems involves spraying plants with a mixture of soap and water,

although in some cases, insecticidal soap may be necessary.
