The benefits of the mosquito-repellent plant are clear from its name: it can repel mosquitoes, and its emerald-green leaves also have a fine ornamental effect. Such a plant naturally makes countless people grow it in pots, so mass propagation of the mosquito-repellent plant is imperative. So how do you propagate the mosquito-repellent plant? Below is an illustrated guide to the propagation methods of the mosquito-repellent plant

I. How to propagate the mosquito-repellent plant: cuttings / sowing

Like most indoor potted plants, the mosquito-repellent plant can be propagated by cuttings. In addition, after flowering the mosquito-repellent plant can bear fruit, and with seeds it can naturally be sown. So how to propagate the mosquito-repellent plant comes down to two methods in general: cuttings and sowing, and both test your potting skills. Let's look at the correct way to do it below.

II. Illustrated guide to the propagation methods of the mosquito-repellent plant

(1) Cutting propagation method for the mosquito-repellent plant

1. Selecting cuttings

To propagate the mosquito-repellent plant by cuttings, you first have to select the cuttings; if they are chosen well, more than half of the whole propagation process is already a success. In March to April, you can select one-year-old semi-lignified leafy softwood shoots and cut them into 12 to 15 cm cuttings to serve as the cuttings.

Treating the cuttings: soak the lower end of the cuttings in rooting powder for 30-40 minutes, then place the cuttings in a cool, ventilated place to dry for several hours.

2. Cutting method

When the cut surface of the cutting is dry and has formed a film, insert it into a pot prepared in advance with growing medium (following the mosquito-repellent plant's growing method, choose loose, slightly acidic soil). Pay attention to strengthening water management; the survival rate can generally reach over 90%. Four hours after inserting, water thoroughly again, and afterward keep the potting soil moist, neither too dry nor too wet; roots can form after 3 weeks.

3. After-planting care

After completing the above steps, the cutting propagation of the mosquito-repellent plant is basically done, and only care remains afterward. In early spring, place it indoors in a warm, bright spot and keep the room temperature at around 20°C; in about 1 month it will sprout and root. Then transplant it separately.

(2) Sowing propagation method for the mosquito-repellent plant

Besides cuttings, the mosquito-repellent plant can also be propagated by sowing. If propagating by sowing, sow the mosquito-repellent plant seeds in early March into clean fine sandy soil at a depth of about 3 cm. When growing the mosquito-repellent plant indoors, keep the room temperature at around 20°C, so that after 1 month the sown seeds can sprout. The mosquito-repellent plant grows quite fast, so remember to repot it once a year.

Overall, the mosquito-repellent plant has fairly strong vitality, and it can be propagated by either cuttings or sowing, but the method most suitable for the vast number of flower lovers is still cuttings. So flower lovers who want to turn one pot of mosquito-repellent plant at home into many pots should quickly try it themselves; even beginners will find it simple to do. That's all the editor has to introduce about the propagation methods of the mosquito-repellent plant, and I hope it helps everyone.

Flowers suitable for sowing in spring

The whole year's work depends on a good start in spring. Some flower lovers don't know which flowers are suitable for sowing in spring, so below is a list of some flowers that can be sown, along with the sowing temperatures and some small sowing methods.
