🌿 Potassium Deficiency

Potassium deficiency can also lead to marginal browning of leaves, signaling an overall decline in tree health.

This nutrient is crucial for disease resistance and overall vitality, making it important to monitor nutrient levels.

🐜 Pest Infestations

🐞 Aphids

Aphids can wreak havoc on your Rowan tree, causing curling leaves and leaving behind a sticky residue.

This not only weakens the plant but also makes it more susceptible to secondary infections, including brown spots.

🕷️ Spider Mites

Spider mites are another pest to watch for. They create fine webbing and stippling on leaves, leading to browning.

Regular monitoring is key for early detection and effective management of these pests.

Understanding these causes will help you take proactive steps in maintaining your Rowan tree's health. Next, we’ll explore how to diagnose brown spots effectively.

Diagnosing Brown Spots
