Rosemary is a beloved herb for its fragrance, culinary uses, and medicinal properties. However, it can be challenging to keep rosemary plants alive and thriving year-round, especially in areas with harsh winters or scorching summers. With the right techniques and care, you can enjoy your rosemary plant throughout the year. In this article, we will delve into the world of rosemary care, providing you with a detailed guide on how to keep your rosemary plant alive and healthy year-round.
Understanding Rosemary’s Needs
Before we dive into the specifics of keeping rosemary alive year-round, it’s essential to understand the plant’s basic needs. Rosemary is a Mediterranean native, meaning it thrives in warm, dry climates with well-draining soil. It requires full sun to partial shade, depending on the climate, and consistent watering.

Rosemary’s Climate Requirements
Rosemary is sensitive to extreme temperatures, and its hardiness varies depending on the cultivar. In general, rosemary can tolerate temperatures between 40°F and 90°F (4°C and 32°C). Prolonged exposure to temperatures below 30°F (-1°C) can be detrimental to the plant, while temperatures above 100°F (38°C) can cause stress and lead to root rot.
Winter Care
In areas with cold winters, it’s crucial to protect your rosemary plant from frost and freezing temperatures. You can bring your rosemary plant indoors during the winter months, placing it in a sunny windowsill or under grow lights. If you cannot bring your plant indoors, consider mulching around the base to retaining heat and protect the roots from freezing. You can also use a breathable cloth or sheet to cover the plant, shielding it from harsh winds and frost.
Year-Round Care Techniques
To keep your rosemary plant alive and thriving year-round, follow these essential care techniques:
Rosemary requires regular watering, but it’s crucial to avoid overwatering, which can lead to root rot and other problems. Water your rosemary plant when the top inch of soil feels dry to the touch, reducing frequency during the winter months when the plant is dormant. Fertilize your rosemary plant during the growing season (spring and summer) with a balanced fertilizer, following the manufacturer’s instructions for application rates.
Pruning is also essential for maintaining a healthy, bushy rosemary plant. Regular pruning encourages new growth, prevents the plant from becoming leggy, and promotes root development. Prune your rosemary plant in the spring, removing any dead or damaged branches, and shape the plant to maintain its desired form.
