🥀 Why Are Rhubarb Leaves Turning Yellow?

🥬 Rhubarb Leaves: Yellowing Causes

Rhubarb foliage 🌺 can turn yellow for various reasons. One potential cause is a nutrient deficiency, where the greenery is not receiving adequate essential elements to remain healthy. Excessive watering and inadequate drainage can also result in yellowing leaves, as the plant’s roots can become overly saturated and suffocate. Furthermore, pests and diseases can also cause the foliage to yellow. It is crucial to determine the specific cause in order to address the issue and ensure the plant’s well-being.

Possible Causes:

Nutrient deficiency
Excessive watering and inadequate drainage
Pests and diseases

For 🥫 nutrient deficiencies, three main elements can cause rhubarb foliage 🌺 to yellow. Nitrogen deficiency often causes the lower leaves to yellow, while potassium deficiency impacts the leaf edges.
