What is the disease of golden leaves and dead leaves?
Although Jin Yezi likes water, there can be no water in the basin soil. Once there is excess water, the roots of plants will rot and the leaves will turn yellow and rot.

Solution: It should be placed in a well-ventilated and bright place, so that the excess water can evaporate as soon as possible, cut the rotten leaves from the middle and disinfect the incision. Usually, the amount of watering should be well controlled, as long as the soil is wet and there can be no water accumulation, and a certain amount of Bika water-soluble fertilizer can be applied.

Data expansion

Golden leaves (Hypericum plants of Verbenaceae) generally refer to Hypericum plants. Hypericum (Duranta erecta 'Golden Leaves') is a perennial evergreen shrub of Verbenaceae and Hypericum, with opposite leaves, serrated edges, oval or ovate-lanceolate, papery, golden yellow in new shoots and leaves, yellow-green and light green in old leaves. Racemes are terminal or axillary, usually arranged in panicles; Calyx tubular, hairy, ca. 5 mm long, 5-lobed, 5-angled; The flowers are small, tall, disc-shaped, the corolla is blue-purple, the fruit is round or nearly ovoid, golden yellow, shiny, about 5 mm in diameter, red and yellow when mature, and the fruit is rarely seen in seedling surgery.

Morphological characteristics: perennial evergreen shrub, the stem is 3-5 meters high; Multi-branched, opposite leaves, serrated edges, ovate or ovate-lanceolate leaves; The new shoots and leaves are golden yellow, and the old leaves are yellow-green and light green. Racemes are terminal or axillary, usually arranged in panicles; Flowers small, saucer-shaped, corolla blue-purple, 5-lobed; The fruit is round or nearly ovoid, golden yellow, shiny, about 5 mm in diameter, red and yellow when mature, and fruit is rarely seen on seedlings that are often pruned.

Growing environment: Forsythia suspensa is a positive plant. False forsythia likes sunny places, high temperature and humid climate, and is not tolerant of shade and weak in cold resistance. The optimum temperature for growth is 22-30℃, and it should not be lower than 5℃ in winter, so as to avoid cold injury, water and humidity resistance and drought resistance.

Distribution: Forsythia suspensa is native to tropical South America, and has been introduced and cultivated in tropical areas all over the world from the West Indies, Mexico to Brazil.

Growth habit: Forsythia suspensa is strong in germination and branching ability, and can germinate in all seasons without dormancy; Extremely resistant to pruning, the more frequent pruning, the stronger the branch germination, the stronger the tree potential and crown, and the brighter the color.

Main value

Garden hedges: In the garden green space, hedges are often used as a space separation and barrier, and can also be used as a background or embedded around flower beds, flower borders and ornamental lawns. Hedgehogs are widely used in sidewalks and green belts as road isolation belts. Forsythia suspensa is more than 3 meters high, with golden and bright tender leaves, strong branching rate, pruning resistance and prickly branches. It can be used as a short hedge (below 50 cm in height), a middle hedge (50- 120 cm), a high hedge (120- 150 cm) and a tree wall (65438 cm) as required.

Flower border of flower bed: flower bed is a certain geometric figure composed of garden plants of different colors, which is used for flower viewing, leaf viewing and viewing. Flower beds are generally arranged in the center of the square, at the intersection of roads, at the center or on both sides of wide roads, such as clock flower beds, pattern flower beds and ribbon flower beds. Flower border is generally arranged on both sides of roads, garden boundaries and building foundation walls, which is a landscape type designed by combining grass flowers with woody plants.
