How to Grow Rosemary? Detailed Guide to Growing Methods and Precautions

Rosemary, also known as dew of the sea and tansy, is a natural aromatic plant that gives off a fresh fragrance during its growing period, which can refresh the mind and invigorate the spirits. In particular, its stems, leaves and flowers have a pleasant scent, making it very effective for purifying the air when kept at home. Below is an introduction to the growing methods and precautions for rosemary.

I. Growth habits of rosemary

Rosemary likes a warm and humid environment. It grows slowly when the temperature is relatively high, and grows faster in winter when the weather is clear and there is no cold wave.

Rosemary has many leaves, which are leathery, so it is relatively drought-tolerant; keeping the soil slightly moist can meet its water needs. However, the soil used for planting should have good drainage, which is more conducive to its growth.

In addition, note that in a natural environment, rosemary that has grown for many years is a shrub, but potted rosemary kept at home has a smaller plant shape and grows slowly, so it is difficult to see it become woody.

II. Growing methods for rosemary

1. Flower pot

Rosemary is a type of herb and likes a cool and dry environment, so the flower pot is very important for its growth. An unglazed clay pot has the best breathability and can be a key consideration. As for the pot size, one about 20 cm in diameter is fine. If it is too large, the amount of watering is hard to control, and since rosemary grows slowly, it does not need too much growing space.

2. Soil

As for the soil, ordinary garden soil is enough; add a small amount of fertilizer to the soil before planting.

3. Fertilizing

Fertilizing about two or three times a year is enough; use fully decomposed organic fertilizer and place it in the soil at the edge of the flower pot. Applying light fertilizer frequently is also fine, and the amount of fertilizer used at one time does not need to be too much. Fertilize appropriately according to the plant's growth condition.

4. Watering

As for watering, more water is needed in summer. Generally, when the temperature is high in summer, do not water at noon; water once each in the morning and evening. In other seasons, generally water once a week. During care, water according to the condition of the potting soil; if it is dry and whitish, it needs watering.

5. Temperature

Rosemary is a relatively cold-tolerant plant. In winter it can overwinter on a semi-enclosed balcony, and around -5°C is no problem. So there is no need to take warming measures in winter, and it still will not freeze to death. But if the winter temperature in your area is below -10°C, it is recommended to move it indoors! Summer temperatures are relatively high, so ventilate and cool it in time to promote its growth.

III. Precautions for growing rosemary

1. Do not pour large amounts of water

Actually, gardening enthusiasts all water based on experience. Those growing rosemary for the first time need to note that in high summer temperatures, although more watering is needed, you cannot pour large amounts of water, as the plant is very likely to wilt and its growth will slow down. In addition, perennial plants can also show such conditions if watered improperly.

2. Do not use chemical fertilizers

After rosemary blooms, it needs a sufficient amount of fertilizer to promote longer flowering, but it is best not to use chemical fertilizers to avoid burning the seedlings. For ordinary home growing, you can also water it with a little fermented rice-washing water.
