How to grow variegated greater periwinkle? Detailed guide to cultivation methods and precautions

Division

Propagation is best done in spring. At this time, cut off the old branches from the previous year, dig out the plants and separate them, replant them separately, and water thoroughly; layering propagation is done during the growing season.

Cuttings

Propagation can be done throughout the year. For the cutting medium, use perlite, vermiculite or sand with good water retention (growing season). For autumn and winter cuttings, it is best to do them in a greenhouse or cold frame; for winter cuttings in a greenhouse using an electric heating bed, the rooting rate is even higher. Greenhouse cutting costs are too high, so to obtain a large number of plants, you should choose to take cuttings in an outdoor cutting bed during the growing season. Select robust, well-developed branches as cuttings. The length of the cuttings should be determined by the season; in winter they should be longer, about 10-13 cm; in summer, when temperatures are high and water evaporation is great, the cuttings should not be too long, about 8-10 cm (2-3 nodes). Keep 2 leaves at the top, cut the lower part down to the node roots, and bury in perlite or sand, then water thoroughly. When taking cuttings, 1-2 nodes must be buried in the sandy soil, and press firmly and tap down, watering in time to keep moist. To reduce leaf transpiration and prevent leaf wilting, when summer sunlight is strong, a shade net with 30%-50% shading rate can be set up above the cutting bed, shading for about 20 days or so, or take cuttings under a shade shed. After the young seedlings begin to root, remove the shade net, control moisture, and increase light. Rooted plants should be transplanted in time; when planting, put 3-4 plants per pot or per clump, so they take shape quickly and have high ornamental value. If transplanted to an outdoor nursery bed in late autumn, cold protection measures should be taken in winter, such as covering with sawdust, straw mats, etc.

I. Ecological habits of variegated greater periwinkle

Variegated greater periwinkle likes light and tolerates shade, and is also tolerant of low temperatures. Under a temperature condition of -7°C, there is no frost damage even when planted in the open ground.

Variegated greater periwinkle is evergreen all year round. The vines produced by tillering and the violet-colored small flowers that bloom in March cover the ground like a flower-studded green carpet, making a very spectacular scene. It is a relatively ideal groundcover material for both foliage and flower appreciation. It has strong adaptability, is not strict about soil requirements, and grows quickly.

II. Cultivation methods of variegated greater periwinkle

1. Propagation: Division and cutting propagation are commonly used. Division can be done every spring by digging up the stems and leaves together with the creeping stem nodes and planting them separately. For cuttings, in the plum rain period from June to July, cut robust branches 10 cm long, select 1-2 internodes and insert them into leaf mold soil, and they will root in about 20 days or so.

2. Temperature: Variegated greater periwinkle likes warmth. The most suitable growth temperatures are: 18-20°C from April to August, and 13-18°C from September to March of the following year. Variegated greater periwinkle is relatively cold-tolerant and can endure low temperatures of about 10°C. Moving variegated greater periwinkle indoors allows it to overwinter safely. Even if the aboveground part dies from frost damage, it can still sprout and grow branches the following spring. But potted plants are best kept at a temperature of about 5°C.

3. Light: Variegated greater periwinkle tolerates shade and can grow healthily as long as there is scattered light. From October to April of the following year, if variegated greater periwinkle can be given sufficient light, it is more conducive to its growth. Variegated greater periwinkle avoids strong direct sunlight exposure, otherwise it easily causes scorching of leaf tips and leaf margins, so shading should be provided from May to September.

4. Watering: Variegated greater periwinkle likes a moist environment and can tolerate waterlogging. During the growth period, water should be supplied sufficiently to keep the potting soil moist, and water can also be sprayed on the leaves to increase the humidity of the growing environment for variegated greater periwinkle. When overwintering, watering needs to be controlled, keeping the potting soil in a relatively dry state.

5. Fertilizing: Because variegated greater periwinkle grows rapidly, it needs timely replenishment of the nutrients required for growth. A fertilizer combining nitrogen, phosphorus and potassium should be applied as a top dressing 1-2 times a month to promote vigorous growth of variegated greater periwinkle and make the markings on the leaves brightly colored. After autumn begins, stop applying nitrogen fertilizer and increase phosphorus and potassium fertilizer to help improve the cold resistance of variegated greater periwinkle. Stop fertilizing in winter.

6. Pruning: Young variegated greater periwinkle plants should be pinched back 1-2 times, and given good fertilizer and water management, so that variegated greater periwinkle quickly forms an ideal crown width. When the tips of the branches of variegated greater periwinkle grow too long, the length can be controlled by pinching and tip pruning, promoting more luxuriant growth of variegated greater periwinkle. For variegated greater periwinkle whose growth vigor has weakened, heavy pruning can be carried out in spring together with repotting, to adjust the growth vigor and restore normal growth of variegated greater periwinkle.

7. Pests and diseases: Wilt disease, canker disease and leaf spot disease often occur, and can be controlled by spraying equal-part Bordeaux mixture. Pests include scale insects and root-knot nematodes. For scale insects, spray with 25% phosmet emulsifiable concentrate at 1000 times dilution; for root-knot nematodes, use 3% carbofuran granules for control.

8. Application: Variegated greater periwinkle is deep green all year round, with variegation along the edges. In April to May, blue flowers bloom one after another from the leaf clusters, appearing very elegant. It is often potted or arranged in hanging baskets indoors, by windows, or on balconies. It is a good vertical foliage plant and groundcover plant.

The above isthe cultivation methods of variegated greater periwinkle. I hope everyone, after reading this, has a better understanding of growing variegated greater periwinkle and can grow their own variegated greater periwinkle even better.
