What are the cultivation methods for variegated greater periwinkle?
1. Temperature:
Variegated greater periwinkle likes warmth, and the most suitable temperature for growth is: 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 around 10°C. Moving variegated greater periwinkle indoors allows it to overwinter safely. Even if the aboveground part dies back due to frost damage, it can still sprout and grow branches the following spring. However, potted plants are best kept at a temperature of around 5°C.
2. Light:
Variegated greater periwinkle is shade-tolerant 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 the growth of variegated greater periwinkle. Variegated greater periwinkle dislikes intense sunlight exposure, otherwise it easily causes the leaf tips and leaf margins to scorch, so shading should be carried out from May to September.
3. Watering:
Variegated greater periwinkle likes a humid environment and can tolerate waterlogged conditions. During the growth period, water should be supplied sufficiently to keep the potting soil moist, and water should also be sprayed on the leaves to increase the humidity of the growing environment for variegated greater periwinkle. During overwintering, watering needs to be controlled to keep the potting soil in a relatively dry state.
4. Fertilizing:
Because variegated greater periwinkle grows rapidly, the nutrients needed for growth must be replenished in time. A fertilizer combining nitrogen, phosphorus, and potassium should be applied 1-2 times per month to promote vigorous growth of variegated greater periwinkle and make the variegation colors on the leaves vivid. After autumn begins, nitrogen fertilizer should be stopped, and phosphorus and potassium fertilizer should be increased to help improve the cold resistance of variegated greater periwinkle. Stop fertilizing in winter.
5. 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 variegated greater periwinkle branches grow too long, the length can be controlled by pinching and tip pruning, prompting more luxuriant growth of variegated greater periwinkle. For variegated greater periwinkle whose growth vigor has declined, heavy pruning can be carried out in spring along with repotting to adjust the growth vigor and restore normal growth of variegated greater periwinkle.
The above is an introduction to the cultivation methods for variegated greater periwinkle. Below, let us look at the precautions for cultivating variegated greater periwinkle!

Cultivation methods for variegated greater periwinkle
Variegated greater periwinkle can be propagated by division, preferably 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 carried out during the growing season.Variegated greater periwinkle is easy to propagate and can be propagated by cuttings, division, and layering, with cutting propagation as the main method. Cutting time: before sprouting in spring; during the plum rain season; and September-October are all suitable for cuttings.

When planted in the open ground, it generally remains green and evergreen all year round.
Cutting propagation of variegated greater periwinkle can be carried out throughout the year. The cutting medium uses perlite, vermiculite, or sand with good water retention (during the growing season). For cuttings in autumn and winter, it is best to carry them out in a greenhouse or cold frame; for cuttings in winter in a greenhouse using an electric heating bed, the rooting rate is even higher. Cutting in a greenhouse costs too much. To obtain a large number of plants, outdoor cutting beds should be selected for cutting during the growing season. Select healthy, plump branches as cuttings. The length of the cuttings should be determined according to the season. In winter it should be longer, about 10-13 cm; in summer, when the temperature is high and water evaporation is large, the cuttings should not be too long, about 8-10 cm (2-3 nodes). Keep 2 leaves at the upper part, cut the lower part to the node root, bury it in perlite or sand, and water thoroughly. When cutting, 1-2 nodes must be buried in river sand soil, and pressed firmly and compacted, with timely watering to maintain moisture. To reduce leaf transpiration and prevent leaf wilting, when summer light is strong, a shade net with 30%-50% shading rate can be set up above the cutting seedbed, shading for about 20 days, or cuttings can be taken 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, use 3-4 plants per pot or per clump, so that 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.
Cultivation and management of variegated greater periwinkle:
It likes a warm and sunny environment, and is also shade-tolerant, cold-tolerant, and relatively drought-tolerant, but in more shaded places, the yellow patches on the leaves become lighter, so it is suitable for planting under sparse woods. It likes relatively fertile, moist soil. Greater periwinkle cultivation requires loose, humus-rich sandy loam. For potting, a mixture of leaf mold, garden soil, and river sand can be used as the substrate. Multiple plants can be planted in each pot at the same time, and pinched back in time, so it can quickly take shape. To promote more branching, pinching can be carried out multiple times during the growing season, and mounding soil at the nodes can produce more adventitious roots and promote the growth of vines. Water should be given in dry weather, and drainage should be noted in the rainy season. Because it grows fast, during the growth period it should be watered sufficiently to keep the potting soil moist, and at the same time apply liquid fertilizer 1-3 times per month to ensure rapid growth of branches and vines and glossy dark green leaves. It is suitable for a bright light environment. But in midsummer, avoid direct strong light to prevent burning the leaves; appropriate shading is necessary, and a semi-shaded environment is best. Although greater periwinkle growth prefers warmth, it is also cold-tolerant, and in winter it can tolerate low temperatures of around 0°C. Greater periwinkle has strong adaptability and grows fast, and can maintain good color all year round except in severe cold, so it is easy to cultivate and widely used. When planted in the open ground, it generally remains green and evergreen all year round. Wilt disease, canker disease, and leaf spot disease often occur, and equal parts Bordeaux mixture can be sprayed for control. Pests include scale insects and root-knot nematodes. Scale insects can be killed by spraying 25% phosmet emulsifiable concentrate at 1000 times dilution, and root-knot nematodes can be controlled with 3% carbofuran granules.
