How to grow golden-edged oval-leaf privet? Detailed explanation of cultivation and management measures

The scientific name of golden-leaf privet is golden-edged oval-leaf privet. It likes light and tolerates slight shade, prefers warmth and humidity, is suitable for slightly alkaline soil, is slightly cold-resistant, and has strong resistance to air pollution. In urban and rural greening, it is often used for hedges, and at present, cuttings are commonly used for expanded cultivation.

1. Cutting preparation and cuttings

When pruning, select robust current-year, semi-lignified branches with obvious golden edges (for spring cuttings, the middle and upper parts of the previous autumn shoots can be selected), and cut them into cuttings. The cuttings should be 5-10 cm long and have 2-3 nodes, with a flat cut at the top and a slanted cut at the bottom. For individual larger leaves, cut off another 1/3 to 1/2 from each leaf, then soak them in clean water for 12 to 24 hours. If conditions permit, soaking them in 75 ppm 2.4-D for half an hour gives even better results. After the above treatment, insert the cuttings at a spacing of 3 cm between plants and 8 cm between rows. The insertion depth should preferably be 1/3 to 1/2 of the cutting.

2. Management after cutting

After cutting, the cuttings begin to root 15 to 20 days later, and the root differentiation process is basically completed in about 40 days. Within 40 days after cutting, special attention should be paid to heat preservation and shading. Before transplanting, spray the leaves with a 0.5% compound solution every 20 days to promote growth. Ninety days after cutting, bed-changing transplanting can be carried out on cloudy and rainy days. During bed changing, they must be transplanted with soil, and sufficient settling water should be watered in time, and depending on the weather, moisture should be maintained and shade provided for about one week.

3. Common diseases

Privet rust: On infected leaves, round brown spots appear on the surface and gradually become sunken, while the corresponding part on the back of the leaf bulges. The mesophyll in the diseased area thickens and appears yellow or purplish red, and later many cup-shaped rust spore receptacles form on the raised spots. Rust spore receptacles also occur on leaf stalks, and infected leaf stalks become slightly swollen. When the disease is severe, the leaves become deformed and die. April to June is the peak period of disease occurrence. Fallen leaves should be removed at any time and burned in a concentrated manner. At the same time, spray 1:200 Bordeaux mixture.

4. Common insect pests

Scale insects: When outbreaks occur, control can be carried out on newly hatched nymphs by spraying with 50% fenitrothion 1000-fold solution on sunny days.
