Rosmarinus Cultivation Methods and Precautions
Today's small experience sharing: a brief introduction to the knowledge of growing rosemary flowers, let's take a look together!
Spring has come, for people who often use their brains, do they often feel dizzy and sleepy at noon, with a blurred mind? Today, I recommend a plant with high appearance, refreshing and edible, which is rosemary.
I. Brief Introduction to Rosemary
Many flower friends should have heard of rosemary. It is a commonly used natural spice in cooking, with a pleasant aroma emitted from its leaves, enhancing memory and keeping the mind clear, especially suitable for students and people with excessive mental exertion.
Rosemary looks like grass, but it is actually a shrub, so it is perennial and can be trained into various shapes. Many flower friends train rosemary into a lollipop shape, which is very ornamental. Image
Rosemary prefers a warm climate and is native to the Mediterranean coast of Europe and North Africa. It has been introduced to China early and is widely cultivated in most parts of southern China and the Shandong region. Rosemary essential oil is commonly used in spices, air fresheners, insect repellents, as well as in the daily chemical industry for disinfection and pest control. Nowadays, rosemary is also commonly used in gardening.
II. Rosemary Cultivation Methods and Precautions
The maintenance of rosemary is not very difficult. When managing potted plants, you can focus on the following six points.
1. -- Pot Selection --
Rosemary grows relatively slowly, and due to its leathery leaves, it is relatively drought-resistant and does not tolerate excessive moisture. To avoid waterlogging and root rot, which can cause withering, it is recommended to use a pot with good ventilation or a terra cotta pot for planting. The diameter of the pot should not be too large, about 20cm is sufficient.
2. -- Potting Soil Configuration --
Since rosemary does not tolerate excessive moisture, it is recommended to use a loose and breathable sandy loam soil for potted plants. Of course, you can also use a general nutrient-rich soil, with an additional 1/5 of particle soil to increase ventilation and water permeability. When planting, you can add an appropriate amount of fermented organic fertilizer or controlled-release fertilizer as a base fertilizer.
3. -- Light Control --
Rosemary prefers sunlight and has a certain tolerance for shade. If you want rosemary to grow rapidly and the plants to be strong, it is best to maintain sufficient sunlight in spring, autumn, and winter, and provide appropriate shading in summer, which is more conducive to the growth of rosemary.
If you want to train it into a lollipop shape, you definitely need sufficient sunlight, because in environments lacking sunlight, rosemary branches tend to grow horizontally and easily develop adventitious roots. For flower friends who want to propagate, they can obtain new plants by layering the horizontal branches. But if you want to train it into a lollipop shape, it is different.
4. -- Fertilization and Water Management --
Although rosemary is tolerant of poor soil, if you want it to grow faster, it is still necessary to fertilize regularly. You can apply a small amount of compound fertilizer or a balanced nutrient solution every 15-20 days to promote the growth of rosemary. Especially after pruning and harvesting, it is recommended to apply fermented organic fertilizer or controlled-release fertilizer in time to supplement nutrients.
When watering rosemary, it is important to water thoroughly after the soil is completely dry. Many flower friends do not know how to understand "watering thoroughly after the soil is completely dry". In the book "How to Grow Flowers from Scratch", it introduces in detail the principles and methods of watering potted plants, which can be used as a reference for those who don't know how to water.
Rosemary is relatively drought-resistant and does not tolerate excessive moisture. Before watering each time, you can water when the pot feels significantly lighter. Do not water too much, especially in summer, as excessive watering or waterlogging can easily cause the whole plant to wither, so it is better to be a little dry than to overwater. Flower friends who like to water are recommended to use terra cotta pots.
5. -- Temperature Control --
Rosemary is relatively cold-tolerant and can safely overwinter in temperatures as low as -5 degrees. In colder regions, it is recommended to overwinter indoors. In the hot summer, it is necessary to provide appropriate shading and maintain good ventilation, not only the environment but also the rosemary plant itself needs ventilation.
The bottom old leaves and yellow leaves should be removed in time, and the weak branches and withered branches should also be cut to keep the part of rosemary close to the potting soil well ventilated, which can effectively reduce the incidence of rosemary diseases and the probability of sudden withering.
6. -- Pruning --
Pruning is very important for promoting the growth of rosemary. Long-term lack of pruning can cause the branches of rosemary to grow horizontally and become messy. However, since rosemary grows slowly, excessive pruning can also hinder the growth of new branches. The correct pruning method is to prune no more than half the length of the branches each time.
After pruning, you can remove the apical dominance of the branches to promote the growth of more lateral branches. After multiple prunings, it is also easier to achieve the desired shape.
