Common Causes of Browning
Identifying the cause is crucial for effective treatment:
- Overwatering: Too much water can drown the roots, leading to root rot and brown leaves.
- Underwatering: Rosemary, while drought-tolerant, can suffer from severe dehydration.
- Poor Drainage: Plants sitting in waterlogged soil can experience browning due to oxygen starvation.
- Nutrient Deficiency: A lack of nutrients like iron or magnesium can result in discolored foliage.
- Pests and Diseases: Aphids, spider mites, or root diseases like Phytophthora can cause leaves to brown.
Step-by-Step Solutions to Revive Your Rosemary 🚑
1. Inspect the Soil 🧐
Before taking any action, check the soil's moisture:
- Dig Down: Feel the soil several inches below the surface. If it's soggy, you're overwatering.
- Watering Technique: If it's too dry, adjust your watering schedule to ensure deep, but infrequent watering.

2. Improve Drainage 🛠️
If poor drainage is the culprit:
- Elevate the Pot: Use pot feet or a raised bed to prevent water from pooling at the roots.
- Amend the Soil: Add grit or sand to improve soil structure for better water passage.

3. Address Watering Issues 💧
Adjust your watering based on your findings:
- Overwatering: Reduce watering frequency. Allow the top inch or two of soil to dry out before watering again.
- Underwatering: Deep water the plant once a week, ensuring the soil is thoroughly moistened but not soggy.
