Culture of periwinkle: raise periwinkle soil to use the right, raise periwinkle potted plants watering to pay attention to, more to the top of the periwinkle

1, raise periwinkle soil to use the right

Non-planking breathable well-drained soil is the best, so that the back even if you watered too much A little bit also does not matter. As for how to match the soil, in fact, do not have to ask for so strict, add some nutritious rotting soil, or peat, and then add some garden soil, particles into. How fertile how loose and breathable how to match on the line.

2, raise periwinkle pot plant watering should pay attention to

In the summer high temperature, more than 30 degrees, watering can be a little more watering, if encountered in the rainy season, or has been placed indoors to raise, be sure to pay attention to the ventilation, the soil, if waterlogged for a long time is not good, the soil a little bit of moisture will not have to water again.

3, more to the top of the periwinkle

In the raising of periwinkle, the seedling must hit the top of the head, the growth period, hit the top of the three or four times, so that the flower branch more, more side buds, branches do not have to grow so long, if you want to see the flower of the time a little bit longer, you can be less than a few times to hit the top. If you want to see more flowers, you can top a few times less.

Morphology of periwinkle:

Subshrub, slightly branched, up to 60 cm tall, with watery sap, glabrous or only slightly hairy all over; stems sub-square, striped, grayish-green; internodes 1-3.5 cm long.

Leaves membranous, obovate-oblong, 3-4 centimeters long, 1.5-2.5 centimeters wide, apex rounded, mucronate, base broadly cuneate to cuneate, tapering into petiole; nerves flattened on leaf surface, slightly elevated on leaf abaxial surface, lateral veins about 8 pairs.

Cymes axillary or terminal, with 2-3 flowers; calyx 5-parted, inner surface eglandular or glandular inconspicuous, sepals lanceolate or subulate-acuminate, ca. 3 mm; corolla red, salverform, corolla tube cylindrical, ca. 2.6 cm, inner surface sparsely pilose, throat constricted, bristly; corolla lobes broadly obovate, ca. 1.5 cm in length and width; stamens inserted on upper half of corolla tube but anthers hidden. upper part of corolla tube, but anthers concealed within throat, free from stigma; ovary and disk as characterized in genus.
