Nursery Stock 0 views
Euonymus japonicus, also known as Japanese spindle, is native to Japan. It prefers a warm, humid environment with plenty of sunlight, has strong cold resistance, tolerates shade, and withstands drought and poor soil. It grows best in fertile, loose sandy loam. Propagation is commonly done by cuttings, and rooting is fastest when cuttings are taken during the plum rain season. Select semi-lignified mature branches, 12-15 cm long, and insert them into a seedbed made of half sand and half soil; they root 20-25 days after insertion. Transplanting of seedlings should not be carried out in spring from March to April. Small seedlings can be planted bare-rooted, while large seedlings need a soil ball. Planting

Propagation

Cuttings are commonly used for propagation, and rooting is fastest when cuttings are taken during the plum rain season. Select semi-lignified mature branches, 12-15 cm long, and insert them into a seedbed made of half sand and half soil; they root 20-25 days after insertion.

Cultivation

Transplanting of seedlings should not be carried out in spring from March to April. Small seedlings can be planted bare-rooted, while large seedlings need a soil ball. After planting, the soil must be tamped down firmly and watered thoroughly; potted plants should temporarily be placed in a semi-shaded spot. Keep the soil moist during the growing season and fertilize once every 2 months. Shape the plant by pruning the whole plant. Stop fertilizing in winter.

Pests and Diseases

Leaf spot disease commonly occurs; spray with a 600-fold dilution of 65% thiophanate-methyl wettable powder. Pests include scale insects, moth borers, and geometer moths, which can be killed by spraying with a 1500-fold dilution of 90% trichlorfon technical material.

Applications

The new leaves of Euonymus japonicus are tender green and clean, and the leaves have yellow and white markings, making it clear, elegant, and serene. It is an ideal material for hedges and bonsai, suitable for entrance areas and central flowerbed arrangements, and can also be grown in pots for ornamental viewing. Common varieties include Euonymus japonicus 'Aureus' and Euonymus japonicus 'Aureo-marginatus'.
