A Fragrant and Versatile Herb

Rosemary is a popular herb used for both culinary and ornamental purposes. With its piney, woodsy fragrance and flavor, rosemary enhances a wide variety of dishes including meats, potatoes, breads and soups. It’s also a beautiful plant that looks great in an indoor herb garden. Growing rosemary indoors is relatively easy with the right conditions.

Light Requirements

Rosemary thrives on lots of sunlight. When growing it indoors, choose a spot with abundant natural light, such as a south- or west-facing window. Rosemary needs a minimum of 6 hours of direct sunlight per day. Supplement with artificial lighting if needed.

Soil and Watering

Use a free-draining potting mix and choose a pot with drainage holes. Rosemary prefers its soil on the dry side, so allow the soil to mostly dry out between waterings. Water deeply but infrequently. Too much moisture will cause root rot.

Temperature and Humidity

Rosemary flourishes in warm, dry conditions around 70°F during the day and above 50°F at night. Cooler temperatures can cause leaf drop. Low humidity is preferred, so avoid grouping with other plants that like moisture.

Fertilizer

Apply a balanced liquid fertilizer every 2-4 weeks during spring and summer. Discontinue fertilizing for the winter.

Pruning and Harvesting

Pinch back growing tips to promote bushiness. Harvest rosemary as needed by cutting sprigs above leaf joints. Frequent harvesting encourages new growth.

Common Problems

Overwatering, insufficient sunlight, pests like spider mites or mealybugs. Catch issues early and adjust care accordingly. Discard plants with severe infestations.

Frequently Asked Questions

How big of a pot does rosemary need?

Use at least a 6-8 inch pot. Rosemary has a deep root system and appreciates room to spread out.

Should I mist my rosemary plant?

No. Rosemary prefers dry air and misting can lead to fungal diseases.

How do I get my rosemary to grow faster?

Ensure it gets enough sunlight, prune regularly, fertilize every few weeks, and allow the soil to dry out between waterings. Avoid overwatering.

Can I grow rosemary from cuttings?

Yes. Take 4-6 inch cuttings from the tips of healthy, non-flowering stems. Remove leaves from the bottom half of the stem and place in water or potting mix to root. Keep moist until established.

What causes yellow leaves on a rosemary plant?

This is usually due to overwatering or insufficient sunlight. Allow the soil to dry out more between waterings and ensure the plant gets at least 6 hours of sun per day.
