The best way to determine if your plant starts to need more water is by checking the soil’s moisture level at a depth of about 1 inch below the surface. If the soil dries to this depth, it’s time for deep watering down to the rosemary roots. (Learn How To Wash Berries)
2. Watering Rosemary In Winter
When planting Rosemary, one of the most critical factors is the amount of water it needs. The herb thrives in well-draining soil and requires proper moisture for optimal growth. During winter, however, gardeners must be careful not to over-water their rosemary plants as they are susceptible to root rot because of excess water. Therefore, it’s best to keep the soil slightly damp, but not with too much moisture or wet.
Severe drought can also affect your rosemary plant’s growth during winter. Providing sufficient water at regular intervals is crucial in such cases to prevent the plant from drying out.
3. Weather Affects The Watering Frequency
Rosemary grows well outdoors in a sunny and dry climate. However, the frequency of watering rosemary should vary depending on the weather. Rosemary requires frequent watering during hot weather to prevent the soil from drying out completely. However, it is essential to reduce watering during cooler and wetter weather, as over-watering can lead to root rot.
Rosemary plants prefer slightly drier soil than herbs like basil or parsley.
How Often To Water Rosemary Indoors In Pots?
Watering rosemary seedlings can be tricky, and getting the watering schedule right is essential. Potted Rosemary plants are drought tolerant, so they don’t need to be watered as often as other herbs. Regarding indoor rosemary plants in pots, the watering frequency depends on several factors, like the pot size, humidity levels in your home, and temperature.
You should water your rosemary plant when the top inch of soil feels dry. Over-watering is one of the most common mistakes people make when growing Rosemary indoors in pots. This can lead to root rot and ultimately kill your plant. It’s essential not to leave standing water in the saucer under the pot, since this can also lead to root rot.
How Often To Water Rosemary Grown In Pots Outdoors?
Rosemary is a hardy herb to grow well in pots outdoors. Rosemary requires full sun, so it needs enough water to moisten the soil. When conditions are too damp or humid, powdery mildew can appear.
It is recommended to water Rosemary grown in pots once or twice a week during the summer when the weather is hot and dry. In areas with extremely dry air, it may be necessary to water rosemary plants more frequently. Ensure the soil remains moist but not overly saturated, as this can lead to root rot.
When watering Rosemary in pots, it’s essential to practice deep watering. Water the plant until water drains from the bottom of the pot. This helps ensure that all parts of the plant’s roots receive enough moisture and promote healthy growth.

How To Tell If You’ve Over-watered Your Rosemary Plant
Determining whether you have overwatered your rosemary plant is essential because it can prevent damage to the plant’s roots, which can then lead to plant death. Over-watering is a common mistake gardeners make, especially those who grow Rosemary outdoors for the first time. This herb requires well-draining soil and does not appreciate wet feet as it has an extensive root system that quickly becomes water-logged.
- If you notice yellow leaves, drooping stems, or mold on the soil surface of your rosemary plant, these could be signs you have overwatered the plant. Yellow leaves often show nutrient deficiencies caused by water-logging in the roots.
- Drooping stems are also a sign your potted Rosemary is getting too much water since it struggles to absorb nutrients from its roots when submerged in water for too long.
- Last, mold on the soil surface shows excessive moisture levels in the potting mix or garden bed where your Rosemary is planted.
If you observe any signs, reduce watering and check the drainage holes in your potted rosemary container or garden bed for blockages or obstructions.
Watering Newly Planted Rosemary
Rosemary is a hardy herb that requires minimal maintenance once established. However, it’s crucial to select the plant correctly by providing adequate water during its initial stages to keep your plant healthy.
Over-watering newly planted Rosemary can lead to root rot and kill the plant. To avoid this, ensure you do not over-water the plant. Before watering your planted Rosemary, test the soil’s moisture level by inserting your finger 1-2 inches into the ground. If it feels dry, then it’s time to water your plant.
Rosemary thrives in well-draining soils; therefore, choose pots or areas with adequate drainage holes. The watering schedule depends on humidity and temperature changes where you grow Rosemary.
During hot summer or when you plant Rosemary near heat sources like radiators, rosemary plants may require more frequent watering because of increased transpiration rate.
Best Time For Watering
Watering is a critical aspect of maintaining healthy rosemary plants. The ideal time for watering your rosemary plant is in the morning, since the temperature is not too high, and the direct sunlight has not yet hit the plant.
Watering in the evening means water droplets will stay on leaves and cause fungal infections. Rosemary plants need well-draining soil, and enough water, as they do not tolerate standing in water. Over-watering causes root rot, which is harmful to your plant’s health. To test if your Rosemary needs watering, check if the top inch of the soil feels dry.
The Best Potting Mix For Draining Excess Water
When growing Rosemary in a pot, the key is to provide more moisture for its roots while avoiding overwatering. Using a well-draining potting mix is essential in achieving this balance. It quickly drains excess water from the drainage holes, preventing the roots from water-logging.
One of the best potting mixes for draining excess water combines peat moss or coconut coir, perlite or vermiculite, and sand or grit. The peat moss or coconut coir retains moisture, providing good airflow around the roots. Perlite or vermiculite helps with drainage by creating space between soil particles. Sand or grit adds weight to the mix and further improves drainage.
Overall, using a well-draining potting mix can help prevent root rot in rosemary plants by allowing excess water to escape quickly. It also helps maintain proper moisture levels in the soil, promoting healthy growth and development of your herb garden plants.
Adding a layer of gravel as a base layer is advisable, as this stops the potting mix from clogging the drainage hole when you water your Rosemary. (Read When Is Romaine Lettuce Ready To Harvest)
What To Do If Your Rosemary Plant Develops Root Rot?
Root rot is a common problem faced by most plants, and one of the main reasons for root rot is overwatering, which leads to the soil is too moist for too long. It’s essential to keep the soil well-draining and avoid excess moisture as much as possible. Taking immediate action is necessary if your rosemary plant has developed root rot.
To begin with, remove the affected parts of the plant, including any leaves or stems that turn brown (like the roots will). Next, carefully examine the remaining roots and trim any brown or blackened sections. Repot the plant in fresh soil that drains well; ideally, mix sand or perlite to improve drainage further.
