Japanese euonymus – plant care

Light-loving plant – prefers bright diffused light, as direct sunlight causes yellowing of the leaves and the appearance of burn spots. Needs lots of space and fresh air. Prefers well-breathable, neutral or slightly alkaline, humus soils with good drainage.

In the spring-autumn period, it requires abundant watering, since the soil should always be moist, but not waterlogged. In winter – as needed, excluding the possibility of drying out the soil. Air humidity is not of particular importance, but spraying the plant 3-4 times a week will have a positive effect on its condition. For spraying, you need to use only boiled, settled water containing a smaller amount of dissolved salts so that the sediment does not pollute the pores of the leaves.

The air temperature in summer should not exceed + 25 ° С, and in winter within + 8 + 12 ° С – at a higher temperature, the plant will shed its leaves. In summer, it is recommended to place the euonymus on an open balcony or in a garden in a dark place.

For euonymus, Japanese plant care involves regular feeding once a week, from early spring to late autumn, with organic and mineral fertilizers. Feeding is not required during the dormant period.

Transplantation of young (over 3 years old) specimens is carried out annually, for adults 1 time in 2-4 years into a substrate of sand, leaf, humus and sod land in a ratio of 1: 1: 1: 2 or from peat, sod land and sand in proportions 0.5:3:1.

To maintain the appearance of the plant, it is necessary to carry out pruning from weak and thickening shoots during the entire vegetative period, and in the spring to pinch young shoots for more intensive branching.

Keeping the plant at temperatures that are too high for it leads to damage by various pests, such as red flat mites, scale insects and spider mites. Control measures: spraying with a 0.15% Actellic solution, manually removing damaged leaves and pests.

Euonymus is propagated in spring by dividing the bush and green cuttings, and in summer by seeds.

Before planting, the seeds are stratified at a temperature of + 2 + 3 ° C for 3-4 months, until the seed coat bursts in about 80% of the seeds. Further, the seeds are cleaned from seedlings, pickled in a 0.5% solution of potassium permanganate and stratified in coarse-grained calcined sand or moistened sphagnum, slightly decomposed peat. The substrate for sowing seeds should consist of sand, leafy, humus and soddy soil in a ratio of 1:4:2:1. Japanese spindle tree – when propagating by dividing the bush in the spring, during transplantation, special care must be taken so as not to damage the root system.

When propagated by cuttings – they must be cut in June – July from young and elastic shoots. The cutting should be 4-6 cm long with one internode. It is necessary to root in the substrate: the lower layer is river sand, the upper one is a fertile mixture of sand, leafy, humus and soddy soil (0.5: 4: 1: 2). Rooting occurs in about 1.5-2.5 months.
