Rosemary cultivation methods and precautions

Rosemary is a fragrant plant with both its leaves and flowers exuding an attractive fragrance. Planting it on the balcony or at home can effectively repel mosquitoes. Rosemary is not only an ornamental plant, but also a commonly used culinary herb, similar to shallots and cilantro. It can be used in grilled meats, such as roast beef and lamb, and can also be made into various spices. In addition, rosemary also blooms small lavender flowers, which are fresh and unique and have great ornamental value. Let’s learn about the cultivation methods and precautions of rosemary.

1. Importance of outdoor cultivation of rosemary

Friends who have raised rosemary potted plants will find that it is not suitable for long-term placement in the living room, room or enclosed balcony. If kept indoors for a long time and lacking light, fresh air, wind and rain, the growth of rosemary will be affected and leaves will easily fall off. Therefore, if it is maintained indoors, it should be moved to the balcony as soon as possible. If there is only an enclosed balcony, it is best to place it in a ventilated and sunny place on the windowsill or next to the window. Rosemary is not afraid of wind and rain, nor is it afraid of the sun. Just water it in time as long as the soil in the pot is dry. Occasionally, if you forget to water the plant and see the leaves shrivel, they will return to normal the next day after replenishing water. Rosemary is actually very hardy, so you don’t have to worry too much about drought, as it has a certain degree of drought tolerance. But in the hot and dry summer, more watering is needed. Rosemary is also relatively cold-resistant in winter. It can be placed outdoors at temperatures a few degrees below zero, and it is not easily frostbitten when it snows. Otherwise, rosemary planted in the ground will not grow well.

2. Rosemary watering tips

Rosemary has no special requirements for fertilizer and soil. Ordinary soil can be used for maintenance and frequent fertilization is not required. Of course, if the soil in the pot is more fertile and loose, it will grow faster. When the plant grows up, it needs to be replaced with a larger pot to accommodate its lush growth. Watering is essential for rosemary. When it is grown indoors, it is affected by light, ventilation and temperature, so water less and keep the soil in the pot not too moist. If you water too much in a non-ventilated environment or in a high temperature and non-ventilated environment, the soil in the pot will be wet for a long time, the roots of rosemary will rot, and the capillary roots will not be able to grow normally, which will lead to yellowing, falling or drying leaves.

Therefore, ventilation and sufficient sunlight are crucial. Rosemary is not afraid of exposure to the sun and does not require sun protection in summer. You just need to prevent the soil in the pot from being too dry. During the vigorous growth periods in spring and autumn, appropriate fertilizer addition can promote its rapid growth, making its branches and leaves strong and numerous, and allowing it to grow from a small seedling into a lush large plant.

3. Sunlight and temperature

Rosemary likes light and is suitable for growing in full or half sun environments. The suitable temperature for growth is 15℃ ~ 25℃. During the hot summer months, place it in a shaded area to prevent damage to the leaves. Rosemary can also be propagated by cuttings, with spring and autumn being the best time for propagation. Choose strong stems, cut off the lower leaves and insert them into moist culture soil. Compact them and place them in a semi-shaded environment. Maintain appropriate humidity and they will take root in about 2-3 weeks.

In short, rosemary grows quickly and requires adequate nutrition. During the growth period, compound fertilizer or organic fertilizer can be applied every 2-3 weeks to promote its healthy growth.
