1. Lighting requirements: Rosemary likes plenty of sunshine, so it should be placed in a sunny place. It is best to get at least 6-8 hours of direct sunlight every day. If you maintain it indoors, put it on the balcony or next to the window to ensure that you can receive enough sunshine.
2. Soil requirements: Rosemary likes well-drained soil. Use soil rich in organic matter, such as a mixture of peat and humus. Avoid using too wet or too sticky soil to avoid root rot. In addition, some sand can be added to the soil to increase drainage.
3. Water requirement: Rosemary is a drought-tolerant plant and does not need to be watered frequently. Pay attention to keep the soil moist when watering, but don't over-water. Before each watering, check the humidity of the soil. If the surface is dry, water. In order to prevent water from staying at the bottom of the basin, a transparent basin or tray can be used to collect excess water.
4. Foliar spraying: You can often spray rosemary leaves with water to increase humidity and clean the leaves. Use a manual watering can or sprayer to spray water on the leaves in the morning and evening, so as to avoid spraying water in the strong sunlight, so as not to burn the leaves with water drops.
5. Pruning: Pruning the branches and leaves of rosemary regularly can promote the branching of plants and make them form a more compact appearance. Cutting off withered, injured or too long branches and leaves and keeping plants small and dense are beneficial to conservation and beautification.
6. Fertilization: During the growth of rosemary, some organic fertilizers can be appropriately applied, such as surimi or decomposed compost. Fertilize once a month during the growing season. However, we should be careful not to over-fertilize, so as not to cause overnutrition and affect plant health.
7. Pest control: Keeping rosemary healthy requires regular inspection and treatment of pests and diseases. Common problems are powdery mildew, aphids and aphids. Once problems are found, organic control methods can be used, such as wiping off pests and diseases on leaves and using biological pesticides.
