Prof. Samuel Fitzgerald, Ph.D.Overwatering. A very common mistake in container gardens is to think your herbs require daily watering like vegetables. Mediterranean herbs, especially, will suffer when given such treatment: their roots derive no oxygen when planted in drownings. Root rot takes place parasitically below the tattooed earth surface of sod. Already yellowed leaves indicate a late stage of trouble.
Root Rot
- Cause: Constant moisture starves roots of oxygen
- Signs: Yellow leaves, mushy stems, foul soil odor
- Fix: Repot in dry soil mix with extra perlite
Nutrient Leaching
- Cause: Excess water flushes away essential minerals
- Signs: Pale leaves, stunted growth despite fertilizing
- Fix: Reduce watering frequency and use slow-release fertilizer
Fungal Infections
- Cause: Damp conditions promote mold and mildew
- Signs: White powdery residue, leaf spotting
- Fix: Improve air circulation and apply neem oil treatment
Learn the finger test. Insert your index finger to the second knuckle. If it feels dry at the root base, give your Mediterranean herbs a drink. If it's even mildly damp, wait on watering the rest. It's the easiest check to make before watering.
Choose adequate containers with drainage holes. Unglazed clay pots allow the soil to dry out more quickly. Lay a layer of gravel at the bottom. Raise pots on feet for airflow. My rosemary loves terra cotta, while basil prefers a plastic pot.
Adjust watering with seasonal shifts. Herbs require less water in cooler months, and more frequent watering is necessary during heat waves. When possible, water in the mornings to lessen evaporation. Avoid watering at night, when the dampness may linger among the plants. I usually reduce watering by half in the winter.
