How to sow Madagascar periwinkle? A detailed guide to the latest sowing method

Madagascar periwinkle (Catharanthus roseus) is a plant in the Apocynaceae family, also known as golden marigold, four-season spring, and so on. Madagascar periwinkle not only has very high ornamental value, but its whole plant can also be used as medicine, with effects such as relieving pain and reducing inflammation, promoting sleep and relieving constipation. Therefore, quite a lot of people grow Madagascar periwinkle now, so how should it be sown when growing it? Today the editor brings you the sowing method for Madagascar periwinkle, so let's take a look below!

1. Seed collection time

Before sowing, we first need to do a good job of collecting Madagascar periwinkle seeds. The ripening period of Madagascar periwinkle fruit varies because the flowering time is different, so when collecting seeds, we should mainly collect them as they ripen. After the Madagascar periwinkle fruit matures, its color gradually turns black. The peel easily splits open, and the seeds then fall out and scatter, so we must collect the seeds in time. When the peel color is found to gradually turn yellow and the seeds can vaguely be seen, collection should begin.

2. Sowing time

The sowing time for Madagascar periwinkle is also very crucial, and the sowing time has a direct effect on the growth of Madagascar periwinkle. The suitable temperature for Madagascar periwinkle seeds is generally around 20 degrees, so the sowing time should be decided according to the environment and climate of the region. However, under normal circumstances, most regions sow around April, with the goal of annual cultivation. If you want to advance the sowing time of Madagascar periwinkle, then in early spring you can raise seedlings in a greenhouse, maintain a suitable temperature, and after the temperature gradually rises, move them to open-field cultivation.

3. Seedbed preparation

After deciding the sowing time and collecting the seeds, we also need to choose the sowing seedbed well. The sowing seedbed for Madagascar periwinkle should be chosen in a place with higher terrain, dryness, sufficient light, and normal drainage and irrigation. The sowing soil should maintain sufficient fertility, be loose, and have good permeability; if conditions allow, it can be prepared with materials such as peat and perlite. Then disinfect it with carbendazim, and after the liquid is slightly dry, do the land preparation work well, deeply plow the soil, and then make beds ready for sowing. If you want to increase the emergence rate, then we can place the seeds in warm water, potassium permanganate, and other solutions for germination promotion and disinfection.

4. Sowing method

The sowing method for Madagascar periwinkle is mainly broadcast sowing; simply scatter the seeds evenly and comprehensively over the soil. After sowing, be careful to cover with a layer of fine soil, and do not let the seeds be exposed to light directly. Then water appropriately, and cover with plastic film to improve the soil's moisture retention capacity; after about a week, seedlings can emerge. After the seedlings emerge, remove the film and appropriately increase the light duration. The seedling stage of Madagascar periwinkle grows rather slowly, and after the temperature rises, the growth rate will speed up; at this time, do the thinning work well.

The above is a brief introduction to the sowing method for Madagascar periwinkle. That is all for today's introduction; this article is for reference only, and I hope it can be helpful to everyone!
