how to care for rosemary

That wonderful scent of pine and lemon, the delicate purple flowers, and the tough, needle-like leaves—rosemary is a truly special herb. It’s a staple in the kitchen garden, but it’s so much more than a culinary ingredient; it’s a resilient, aromatic shrub that can thrive for years with the right attention. Whether you’re growing it in a pot on a sunny windowsill or nestled in a garden bed, learning how to care for rosemary is the key to keeping it healthy and productive.

The Golden Rule of Rosemary: Sun and Soil

Rosemary is a child of the Mediterranean, and it craves conditions that mimic its native home. This means it needs as much direct sunlight as you can give it—at least six to eight hours a day. When it comes to soil, think “well-drained.” Heavy, wet soil is its worst enemy. A sandy or gritty potting mix is perfect. If planting in the ground, consider raising the bed or adding plenty of gravel or sand to ensure water drains away quickly from the roots.

How to Care for Rosemary with Smart Watering

This is where many gardeners go wrong. Rosemary prefers to be on the dry side. It’s a drought-tolerant plant that would much rather be a little thirsty than have wet feet. Before you water, check the soil. Stick your finger an inch or two into the dirt; if it feels dry, it’s time for a drink. If it’s still moist, wait a day or two. In the winter, you’ll need to water even less frequently.

Pruning for a Bushier Plant

Don’t be afraid to harvest and prune your rosemary regularly. This isn’t just for your cooking; it’s good for the plant! Frequent, light harvesting of the stem tips encourages the plant to grow bushier and fuller, rather than becoming leggy and woody. Use sharp, clean shears and avoid cutting back into the old, leafless wood, as new growth may not sprout from there.

Overwintering Your Rosemary

Cold, wet winters can be challenging for rosemary. If you live in a colder climate, growing it in a container is a great idea so you can bring it indoors to a sunny spot when frost threatens. Ensure good air circulation to prevent powdery mildew. For garden plants, a layer of mulch around the base can help protect the roots, but the main threat is often cold, damp soil more than the air temperature itself.

With its lovely fragrance and rugged nature, rosemary is a rewarding plant to grow. By giving it plenty of sun, excellent drainage, and a careful hand with the watering can, you’ll be able to enjoy its fresh flavor and beautiful presence in your garden for many seasons to come.
