The Cultivation Method of Euonymus
Euonymus is favored by gardening enthusiasts for its unique pinnate leaf veins and beautiful autumn colors, but many people often encounter problems such as excessive branch and leaf growth and frequent occurrence of diseases and pests during cultivation. As a shrub plant with both ornamental and medicinal value, mastering scientific maintenance methods can help Euonymus show its best posture.
Five Core Elements of Euonymus Maintenance
Temperature and Light Control
Euonymus has a wide temperature range of 10-30°C, but it needs to be moved to a semi-shaded area when temperatures exceed 35°C in summer, and measures such as covering the soil or wrapping the trunk are required in winter. Ensure 5 hours of direct sunlight per day in spring and autumn, and shade 30% during the noon in summer to prevent leaf burn.
Precise Water and Fertilizer Management
Adopt the watering principle of 'moist when dry and wet when seen', maintaining soil moisture at 60% during the spring sprouting period, and combining morning and evening foliar sprays in summer. Apply a phosphorus-potassium compound fertilizer (N-P-K=5-10-10) monthly from March to June, and apply bone meal in autumn to enhance cold resistance. Remember to avoid using high-nitrogen fertilizers such as urea.
Advanced Techniques for Shaping Euonymus
Key Points of Cutting Propagation
The Cultivation Method of Euonymus
Select semi-woody branches in late June, retain 2-3 pairs of leaves, treat the base with ABT rooting powder, and insert into a matrix of perlite:vermiculite=1:1. Maintain an environmental humidity of 80% at 25°C, and gradually increase light intensity after about 15 days of root formation.
Artistic Pruning Techniques
Prune the excessive branches monthly during the growing period, retaining 2-3 buds at the base. Shaping pruning should be done after defoliation, using the 'cutting and storing branches' method to create a cloud-like crown shape, and apply healing ointment to the cut surface to prevent pathogen invasion.
Solutions to Common Problems of Euonymus
Disease and Pest Control
For the Euonymus caterpillar moth, alternate the use of 1.8% abamectin 2000-fold solution and 20% insecticide suspension 3000-fold solution. For the initial stage of root rot, apply metalaxyl 300-fold solution to the roots, and replace the disinfected matrix (carbendazim:soil=1:500) in severe cases.
