How to grow rosemary?
1. Planting environment
Rosemary is a kind of plant that likes sun and warm climate. it has strong drought tolerance and is suitable for planting in sandy loam. because it is afraid of waterlogging, it is necessary to do a good job of drainage in the field, and it is difficult to survive the winter when the temperature is below minus three degrees in winter.
two。 Reproduction method
The main results are as follows: (1) because the seeds of rosemary are small and the germination rate is relatively low, it is recommended to propagate by cutting, cutting 10 to 15 cm twigs from the top of the plant, removing 1/3 of the leaves at the base and inserting them into the rooting medium to take root.
(2) Rosemary can be propagated by striping, pressing the rosemary branches near the bottom in the soil and letting the part of the covered soil take root and then cut off as transplanting seedlings.
3. Pruning method
In order to extract its economic value, the top of the trunk will be removed when it grows to 80 centimeters, which makes the plant low, neat and easy to manage, and allows rosemary to grow branches continuously, produce more branches and leaves, and increase yield. If the growth of rosemary is not controlled, it can grow to nearly two meters high.
4. Fertilization management
Because rosemary is more resistant to barren and needs not much fertilizer, 20 kg / mu of compound fertilizer is usually applied during the seedling growth period, and 15 kg of nitrogen fertilizer and 25 kg of calcium superphosphate are usually applied per mu after harvest.
