At the bud stage, plant growth is noticeably delayed, leaf color becomes lighter and sometimes yellowed, and severely diseased plants are stunted. Tubers are elongated, or one end is more pointed, forming a spindle shape, with

Detailed Explanation of the Training and Pruning Methods for the Slender Spindle Shape of Apple Trees
How do you train and prune apple trees into the slender spindle shape? The slender spindle belongs to the small canopy form and is one of the tree shapes with the fewest scaffold branches and the most fruiting branches, suitable for relatively dense planting, dwarfing rootstocks and spur-type cultivars. Generally the row spacing is 2.5-4.0 m, and the plant spacing is 2.0...

Symptom Identification and Control Methods for Leaf Spot Disease on Japanese Spindle (Euonymus japonicus)
Symptoms: The disease affects the young and old leaves of Japanese spindle (Euonymus japonicus). Yellow-brown spots appear on the upper surface of the leaves and expand into nearly circular or irregular shapes, 4 mm to 14 mm in diameter, with a grayish-white center, light brown concentric rings, and a dark brown slightly raised edge. Dense tiny black mold dots form within the lesions. The spots show through to the underside, though the color on the underside is slightly lighter than on the upper surface. After the lesions dry up, they crack apart from the healthy tissue, eventually forming holes. This often causes early leaf drop. Pathogen: fungus, Cercospora destructiva Rav. of the order Moniliales, class Hyphomycetes, subdivision Deuteromycotina.

Introduction to Several Propagation Techniques for Japanese Spindle (Euonymus japonicus)
There are many propagation methods for Japanese spindle (Euonymus japonicus). Several commonly used methods are briefly introduced below: 1. Cutting method: The cutting method is further divided into hardwood and softwood cutting methods. Hardwood cuttings are carried out between October each year and the end of March of the following year. For units with sufficient source material, the cuttings can be cut slightly longer; for units lacking source material, the cuttings can be slightly shorter. The cuttings are 8 to 15 cm long, and the insertion depth is generally 3 to 5 cm. Roots can grow after 1 month. As long as cuttings are made according to the method introduced below, well-grown seedlings can be obtained quickly: 1
