Planting technique of patchouli

Patchouli is a perennial herb, which normally keeps upright growth and the whole plant is accompanied by aroma. It is widely planted in the south of China. Because patchouli has a volatile oil that releases fragrance, it can be used to make spices and is also an important raw material for making perfumes. This kind of plant can be planted not only in a large area, but also in pots. Today, the editor will share with you the planting techniques of patchouli.

Because the seed germination temperature of patchouli is between 20 °C and 25 °C, and the temperature in spring and autumn is mostly between this, it is very suitable to use sowing to breed young plants in these two seasons. However, it should be noted that if the temperature of the seed growth environment is lower than 17 °C, it will affect not only the budding rate, but also the growth rate of seedlings.

Generally, after sowing, if the growth environment is suitable, it can sprout within 2 weeks, and the emergence rate is as high as 80%. Of course, the process of seed germination should be carried out under the plastic film, and the plastic film should be opened after emergence, and the temperature at the seedling stage should be controlled between 18 °C and 25 °C. When the seedlings grow to 12 centimeters, it will enter the peak growth season, so if potted, it is generally necessary to plant them in pots in time when they grow to 10 centimeters.

Patchouli can not only be eaten as a dish, but also can be used as medicine to treat diseases because of its strong medicinal value. Therefore, we need to do a good job in the maintenance and management of seedling growth, especially in the management of water and fertilizer. After all, we need to collect young stems and leaves from this plant for consumption or medicine, and timely topdressing is an important means to promote plant germination of new branches and leaves.

As we harvest more stems and leaves of patchouli for consumption, we need to increase topdressing to promote its extraction of new branches and leaves, while the seedling growth period is generally dominated by topdressing nitrogen fertilizer, with the continuous growth of seedlings, but also need to supplement phosphorus and potassium fertilizer in time. Of course, if there is rotten cruller, human and animal manure, it is also a very good organic fertilizer. However, fertilization is mainly thin, avoid the use of raw fertilizer.

Usually when the seedlings grow to a height of about 3 centimeters, we need to fertilize for the first time and loosen the soil at the same time. Then, when the seedling height reaches 7 cm and 25 cm, we need to fertilize again and at the same time do a good job of weeding to prevent weeds from competing for nutrients that originally belong to patchouli. However, do not top fertilize after piling up the soil, otherwise it may affect its normal growth.

It should be noted that because patchouli is afraid of flooding, it is necessary to control the amount of water in the process of watering. Generally speaking, the soil is only watered when it is dry. If the soil is still wet, there is no need to water it. In the process of planting and breeding, the seedlings are generally watered once before rooting, and then watered again after transplanting. But if it is a potted plant, due to the limitation of space in the basin, watering can be considered as appropriate.
