How Much Sun Does Rosemary Need?

Rosemary is a popular culinary herb with a woody, fragrant stem that can grow up to 4 feet tall. It’s known for its pungent smell, which makes it perfect for seasoning meat and fish dishes. However, before you plant rosemary in your garden, it’s important to know how much sun the plant needs to thrive.

How Much Sun Does Rosemary Need?

Rosemary is a perennial herb, which means it will grow year-round in most climates. However, it does enjoy lots of sun and needs at least 6 hours of direct sunlight per day. When planted in the ground or in your garden bed, you can use a rosemary plant to fill an empty space between other plants but don’t go too far—it will outgrow them quickly! If you’re looking for something more compact, try planting rosemary in pots; their shallow root systems make them perfect candidates for container gardens.

Does Rosemary Prefer Full Sun?

Rosemary is a plant that can tolerate shade, but it grows best in full sun. It prefers a lot of sun, so if you want to grow rosemary in your garden, make sure you place it in a sunny spot where it will get at least six hours of direct sunlight per day.

Rosemary grows best when it’s planted in soil that’s well-drained and sandy with a pH between 6 and 7.5. The plant can tolerate drought conditions, but if your soil is dry, make sure to water the plant regularly until it becomes established.

Can Rosemary Grow in Shade?

Yes, rosemary can grow in shade. In fact, it’s just as happy living in partial or full shade (as long as the plant gets at least four hours of sunlight each day). However, if you want to see your rosemary thrive and reach its full potential, you’ll have to provide it with lots of light.

In fact, you should be able to see your rosemary leaves from across the room. The more light it gets, the greener and healthier it will be.

Where Does Rosemary Grow Best?

Rosemary grows best in a sunny location with well-drained soil. It can tolerate dry conditions and will grow well in full sun to partial shade.

Soil: Rosemary prefers light, sandy loam with excellent drainage. It will tolerate heavier clay soils, but you may need to water more frequently if your soil is heavy or poorly drained. If you’re planting rosemary from seed and have poor drainage, consider adding garden peat moss or other organic matter to improve the drainage before growing your rosemary seeds or seedlings indoors until they are large enough to transplant outside into their permanent potting containers.

Watering: Rosemary needs moderate amounts of water throughout the summer months—approximately 1 inch every two weeks during hot weather (June through September). In wintertime (November through February), reduce watering by half; allow only about ½ inch every two weeks for healthy growth during this dormant period for rosemary plants.

Can Rosemary Get Too Much Sun?

Too much sun can burn the leaves, which will cause them to be brown and crispy. The plant may also be stunted by too much sun exposure if it’s not given sufficient water.

The plant will be more susceptible to disease if you expose it to too much sun, so that’s another reason why you should avoid over-exposing your rosemary plants.

Signs Your Rosemary Isn’t Getting Enough Sunlight

If you’re growing rosemary in a pot, one of the most common problems is that it’s not getting enough sun.

Here are some signs that your rosemary isn’t getting enough sunlight:

  • The leaves are pale and yellow—not green
  • The plant is thin, spindly, and weak-looking
  • The stems and branches are weak, brittle, and easily snap off when you touch them
  • The plant has few flowers or buds on it (or no flowers at all)


Sunlight is the most important factor in determining how much sun rosemary needs, but it’s not the only one. In addition to sunlight, the amount of water and soil drainage can also affect its growth. The best way to ensure your rosemary gets enough sunlight is by planting it in a location with plenty of direct sunlight—but not too much!
