Looking to enjoy some fragrant and flavorful rosemary year-round, regardless of your garden space? Growing rosemary in pots is the perfect solution! This guide shows you how to grow rosemary in pots, ensuring a healthy, vibrant plant that thrives throughout the seasons.
YayImagesHow to Grow Rosemary in Pots
Here are some essential tips to help you successfully grow and care for rosemary in pots:
1. Choose a Spacious Pot
When planting rosemary in pots, the size of the container is crucial.
Rosemary plants have a robust root system that needs ample space to grow.
Choose a pot that’s at least 12 inches in diameter, like these ones, which not only provides enough space for your rosemary to flourish but also adds a rustic charm to your garden or patio.
Make sure the pot has drainage holes to prevent water from pooling at the bottom, which can cause root rot.
2. Use Well-Drained Soil
Rosemary thrives in well-drained soil, so selecting the right soil mix is essential for healthy growth.
A high-quality potting mix like Miracle-Gro Moisture Control Potting Mix is a great choice as it’s specifically formulated for plants that require excellent drainage.
You can also mix this with some perlite to further improve the soil’s drainage capacity, preventing the roots from becoming waterlogged.
3. Ensure Full Sunlight
Rosemary is a sun-loving herb, so placing your pot in a location that receives at least 6 to 8 hours of direct sunlight each day is vital.
Consider placing your rosemary in a plant stand with wheels to easily move it to the sunniest spot in your home or garden.
This way, you can ensure that your plant gets enough light throughout the day, even if your space has shifting light conditions.

Rosemary is drought-tolerant and prefers to be kept on the dry side.
A moisture meter is the easiest way to monitor soil moisture levels accurately.
This tool helps ensure that you only water your rosemary when the top inch of soil is dry, preventing overwatering and the associated risks of root rot.
It’s better to use a watering can with a long sprout to water directly at the base, avoiding the foliage.
5. Fertilize Lightly
Rosemary doesn’t require heavy feeding, and over-fertilizing can lead to excessive foliage growth at the expense of flavor and fragrance.
Use a balanced, all-purpose fertilizer like Jobe’s Organics Herb Fertilizer Spikes at half strength once a month during the growing season.
These slow-release spikes provide the necessary nutrients without overwhelming the plant.
Be sure to avoid fertilizing in the winter when the plant’s growth naturally slows down.
6. Prune Regularly
Regular pruning is essential for keeping your rosemary plant compact and bushy.
Invest in a good pair of pruning shears to easily snip off the tips of the plant and remove any dead or yellowing stems.
Remember, it’s important to avoid cutting into the woody parts of the plant, as rosemary can struggle to regenerate from these older sections.

Rosemary prefers moderate temperatures and doesn’t fare well in extreme cold or heat.
If you’re growing rosemary indoors, consider using a digital thermometer & hygrometer to monitor the temperature and humidity levels.
This device helps you ensure your plant is in an environment where the temperature stays between 60°F and 75°F, which is ideal for rosemary.
8. Check for Pests
Though rosemary is relatively pest-resistant, it’s still important to regularly inspect your plant for common pests like aphids, spider mites, and whiteflies.
I recommend having a bottle of neem oil on hand, which is an effective and natural solution for treating pest issues as soon as they appear.
Early detection and treatment are key to preventing infestations from spreading and keeping your rosemary plant healthy and vibrant.
9. Repot When Needed
As rosemary grows, it may outgrow its pot, requiring repotting to refresh the soil and provide more space for root development.
Check the roots periodically, and if they’re circling the bottom of the pot or growing out of the drainage holes, it’s time to repot.
When repotting, use a root stimulator to help the plant adjust to its new pot and reduce transplant shock.
Choose a slightly larger pot and refresh the soil to give your rosemary room to grow and thrive.

Rosemary is sensitive to frost and cold temperatures, which can damage or kill the plant.
If you live in a region with harsh winters, it’s essential to bring your potted rosemary indoors before the first frost.
Consider using a frost blanket to protect your plant during unexpected cold snaps.
Place your rosemary in a bright, sunny window, and reduce watering to prevent root rot.
This winter protection will help ensure your rosemary survives the cold months and continues to grow in the spring.
11. Rotate the Pot
To ensure even growth, rotate your rosemary pot every few weeks.
This practice prevents the plant from leaning towards the light source and encourages uniform growth.
Rotating the pot also helps to prevent one side of the plant from becoming overly shaded, which can lead to uneven development.
12. Harvest Frequently
Regular harvesting encourages new growth and keeps your rosemary plant productive.
Use herb scissors to snip off the top few inches of the stems, making sure not to harvest more than one-third of the plant at a time.
Frequent harvesting not only provides you with fresh rosemary for cooking but also keeps the plant healthy and vigorous.
YayImagesMistakes to Avoid When Growing Rosemary in Pots
Now that we’ve determined the best ways to grow and care for rosemary in pots, let’s take a look at what not to do:
1. Using a Small Pot
A common mistake when growing rosemary is using a pot that’s too small.
A small pot restricts root growth, leading to a stressed and stunted plant.
Always opt for a larger pot, such as this large concrete planter, to give your rosemary plenty of room to grow.
2. Overwatering
Overwatering is one of the most frequent issues when growing rosemary in pots.
To avoid this, use a soil moisture meter to check moisture levels before watering.
Ensure the soil is dry before watering, and always use a pot with drainage holes to prevent water from accumulating at the bottom.
3. Using Poorly Draining Soil
Rosemary’s roots need well-drained soil to thrive.
Using heavy or compacted soil can cause water to linger around the roots, leading to rot.
Always use a well-draining soil mix, such as the Miracle-Gro Moisture Control Potting Mix, to ensure your rosemary stays healthy.

Rosemary requires full sunlight to grow well.
Placing your plant in a shaded area can result in weak, leggy growth and reduced flavor.
Ensure your rosemary pot is positioned in a spot that receives ample sunlight each day, and consider using a grow light if natural light is insufficient.
5. Over-Fertilizing
While rosemary benefits from occasional feeding, too much fertilizer can cause lush foliage growth at the expense of essential oils, which diminishes the herb’s flavor.
Stick to a light feeding schedule, using organic fertilizer tablets sparingly to provide just the right amount of nutrients.
6. Pruning Too Aggressively
While pruning is important, cutting back too much can harm the plant.
Avoid pruning into the woody stems, as rosemary has difficulty regenerating from old wood.
Focus on trimming the green, soft parts of the plant with precision pruning shears.

Failing to repot your rosemary when it becomes root-bound can stunt its growth and lead to poor health.
Regularly check the roots by gently removing the plant from its pot; if they’re tightly packed and circling the edges, it’s time to move your rosemary to a larger pot.
8. Failing to Protect from Frost
Rosemary is not frost-tolerant, and exposure to freezing temperatures can kill the plant.
During winter, it’s crucial to bring your potted rosemary indoors to a warm location or use a frost blanket to shield it from frost.
Proper protection ensures your rosemary remains healthy through the colder months.
9. Crowding Multiple Plants
Planting multiple rosemary plants in a single pot can lead to overcrowding, which restricts airflow and increases the risk of disease.
To ensure each plant has enough space to grow and thrive, it’s best to use individual pots.
Providing adequate space helps each rosemary develop a robust and healthy structure.

Though rosemary is generally resilient, it is not immune to pests.
Regularly inspect your plant for signs of common pests like aphids or spider mites, and address any infestations promptly.
Using organic insecticidal soap can help manage pests effectively and maintain your rosemary’s health.
11. Watering the Leaves
Watering the leaves instead of the soil can promote fungal growth and disease.
Always direct your watering to the soil level, using a long sprout watering can to ensure that the foliage stays dry.
This practice helps prevent moisture-related issues and keeps your rosemary plant healthy.
12. Harvesting Too Little
Frequent harvesting not only provides you with fresh rosemary but also encourages the plant to grow new, bushier shoots.
Neglecting to harvest can result in leggy growth and reduced productivity.
Regularly snip off sprigs with sharp herb scissors to stimulate growth and keep your rosemary vibrant and productive.
