Variegated philadelphus blooms many beautiful small flowers every year, interpreting the style of small freshness. Variegated philadelphus is very common in cities. People have seen it but may not know the name of this flower. Variegated philadelphus has a high ornamental value. If you like this small flower, you can try to plant it yourself. The following is an introduction to the cutting method of variegated philadelphus .

Cutting method of variegated vinca

The propagation of variegated philadelphus should be carried out in spring. Spring is the season when everything recovers and grows. Variegated philadelphus will have a faster growth and development in spring, so a large number of propagation and development can be carried out through division, cuttings and other methods. Of course, cuttings can also be carried out in autumn and winter, but they must be carried out in a greenhouse or a sunny bed; in winter, cuttings are carried out in an electric hotbed in a greenhouse, and the rooting rate is higher. However, the cost of cuttings in a greenhouse is too high. To obtain a large number of plants, it is still necessary to choose cuttings in an outdoor cutting bed during the growing season. This can make the propagation and development of variegated philadelphus more economical and efficient.

Variegated philadelphus is easy to propagate. It can be propagated by cuttings, tillers, and layering. Cuttings are the main method of propagation, and cuttings can be carried out all year round. The cutting medium should be perlite, vermiculite or sand (growing season) with good water-retaining properties.

1. Cutting time:

Cuttings can be taken before germination in spring; during the rainy season, from September to October.

2. Cutting method:

Choose one-year-old or current-year strong branches, cut them into about 10 cm long, and have 2-3 pairs of buds for cuttings. The spacing between rows and plants should be 10 cm × 10 cm. Water thoroughly after planting, and build a shed and cover with a shade net to protect against the sun. Keep the soil moist, and transplant them into the field after they survive.

2. Precautions for cuttings

The potted variegated vine should be topped in time to promote branching. Keep the soil moist during the growing period and fertilize once every half a month. Prune appropriately in summer and autumn to control the growth of branches and vines. Planted in the open field, it is generally green all year round.

To promote more branches, you can pinch the top several times during the growing season, and pile up soil at the nodes to grow more adventitious roots and promote the growth of vines. Water it during droughts and pay attention to drainage during rainy seasons. Because it grows fast, it needs to be fully watered during the growing season to keep the pot soil moist. At the same time, apply liquid fertilizer 1-3 times a month to ensure rapid growth of branches and vines and dark green and bright leaves.

It is suitable for bright light environment. However, in midsummer, it is necessary to avoid direct sunlight to avoid burning the leaves; it must be properly shaded, and semi-shaded environment is best. Although Vinca prefers warmth to grow, it is also cold-resistant and can withstand low temperatures of around 0℃ in winter. Vinca is highly adaptable and grows fast. It can maintain its color throughout the year except for severe cold, so it is easy to cultivate and widely used. It is planted in the open field and is generally evergreen all year round. Wilt, ulcer and leaf spot often occur, which can be controlled by spraying with equal amounts of Bordeaux mixture. Pests include scale insects and root wart nematodes. Scale insects can be sprayed with 1000 times diluted 25% phosmet emulsifiable concentrate, and root wart nematodes can be controlled with 3% furadan granules.
