Hello –
Yellow leaves could be a plant disease symptom (see link below). However, a number of problems could lead to yellowing plant leaves. Here are a few:
โข Chlorosis – Commonly caused by a deficiency of iron or manganese, both of which are present but unavailable in high pH soils (pH>7.2).
โข Overwatering – Check the soil around the root zone to see if it is damp and only water as much as the plant needs.
โข Insect Pests – Inspect carefully, especially on the underside of leaves.
โข Too Little Light – Has the plant been moved recently? Are the leaves on the side away from the light source affected?
โข Plant Disease – Fungal problems are responsible for a great deal of damage and are characterized by wilting, scabs, rusts, blotches and rotted tissue. Here’s a link to help identify some of the more common plant diseases. We offer earth-friendly remedies too!
