So if you see yellowing leaves, it's natural to wonder what's going on. In this article, we'll explore some of the most common reasons why rhododendron leaves turn yellow and what you can do about it.

The Reasons for Rhododendron Leaves Turning Yellow

There are several possible reasons why your rhododendron leaves may be turning yellow:

1. Lack of Water

Like all plants, rhododendrons require water to survive. If they don't get enough, their leaves may start to turn yellow or drop off. This could be due to a lack of rainfall or forgetting to water them regularly. In general, you should water your rhododendrons deeply once a week during hot, dry weather.

2. Nutrient Deficiencies

Rhododendrons require certain nutrients, such as iron and magnesium, to keep their leaves green and healthy. If they're not getting enough of these nutrients, their leaves may turn yellow or even brown. This could be due to poor soil quality or lack of fertilization.

3. Pests and Diseases

Rhododendrons are susceptible to a variety of pests and diseases, including lace bugs and root rot. If you see yellowing leaves, it could be a sign of an infestation or infection.
