Rosemary

I’ve lost count of how many rosemary plants I’ve killed over the years. The first few were in Singapore’s humidity—moldy, leggy, and gone within weeks. The problem wasn’t me; it was my approach. Rosemary is a Mediterranean plant. It wants sun, air movement, and roots that never sit in moisture. Once I accepted that, everything changed. Here’s how I grow rosemary now.

Light

Full sun is non‑negotiable. At least 6–8 hours of direct light daily. Indoors, place it in a south‑facing window or under strong grow lights. If your plant gets leggy, it’s begging for more light.

Water

I water only when the top 2–3 cm of soil is bone dry. Then I water deeply until it drains out the bottom. In humid climates, that might mean watering every 10–14 days. The golden rule: when in doubt, wait another day. Rosemary would rather be thirsty than drowned.

Soil

Use a gritty, sharply draining mix. I blend 2 parts coarse sand or perlite with 1 part potting soil and 1 part compost. For containers, add a handful of gravel to the bottom. The goal is roots that dry out quickly after watering.

Climate & Adaptation

Rosemary thrives in dry, sunny, temperate regions. In humid or tropical areas, treat it as a container plant. Move it under cover during rainy spells, and ensure excellent airflow—a small fan indoors works wonders. In cold winters, bring pots indoors or mulch heavily. In hot, dry summers, a little afternoon shade can prevent leaf scorch.

Common Mistakes

• Overwatering: The number one killer. Yellow, drooping leaves usually mean too much water, not too little.
• Poor drainage: Heavy soil holds moisture, inviting root rot. Always test your mix.
• Low light: Indoors, even a bright windowsill may not be enough. Supplement with lights if needed.
• Ignoring airflow: Stagnant humid air encourages powdery mildew. Space plants out or use a fan.

Rosemary rewards patience. Give it the conditions it loves, and it will reward you with fragrance, flavor, and memories of the Mediterranean. Every time I brush a stem, I remember those first failures—and I smile.
