Then choose strong branches as cuttings on the mother plant, ready to rot soil and rivers and equal amounts of mixed loose sandy soil, 1/3 of the cuttings inserted into the soil, do a good job in the later watering, lighting and other maintenance work, half a month will take root. The following are steps of madagascar periwinkle cottage propagation.
Generally, cuttage propagation of Madagascar Periwinkle is carried out from April to July, when the temperature is suitable and the illumination is sufficient, which can satisfy the growth habit of Madagascar Periwinkle. And Madagascar Periwinkle is in the peak growth period at this time, so the survival rate of cuttings will be greatly improved.

Leaf-rot soil and river sand can be mixed in equal amounts to prepare the required soil, and then poured to keep the soil moist and prevent water accumulation.
Cut the treated branches directly into the moist sandy soil, cutting the depth of 1/3 of the branches can be. At this time the temperature rises, it is necessary to pay attention to prevent high temperature and high humidity environments leading to cuttings rotting phenomenon, the temperature should be controlled between 20 ~ 24℃.
Generally, half a month after cuttings, Madagascar Periwinkle branches will quickly grow new roots. During this attention should be paid to control watering, prevent seeper to bring about basin soil too much too wet, the hair root of the influence branch grows. At the same time, when the summer sun is too strong, we should pay attention to shade to prevent the top leaves from being sunburned.

If seeding in this period, the survival rate of Madagascar Periwinkle will be higher, and the breeding will be much more convenient after seeding.
In the Madagascar Periwinkle plant, we need to send it to choose a suitable cultivation of the soil. Madagascar Periwinkle is very strict with soil. If you want the beautiful flowers every year, you need to choose loose soil, well-drained sandy soil, and we can choose rotting leaves, soil, peat and perlite as a 5:4:1 mixing ratio, so the soil is suitable for planting Madagascar Periwinkle.

First of all, before sowing, requires the use of 500 ~ 600 times of carbendazim liquid spraying soil sterilization, sterilization in soil, then sprinkle with Madagascar Periwinkle seeds, cladding layer of fine soil, adequate water, keep the soil moist degree, seeds will germinate after half a month.
After planting, it needs to be maintained until Madagascar Periwinkle quickly takes root. If not germinate, we need to put it in the shade. It does not need fertilization, you just need to keep the soil moist degree. After waiting for the root, we need to give it plenty of sunshine, but the strong sunshine needs to do a good job in shade watered once every 3 days, 20 days of an organic fertilizer, to help germ growth.
