Is there any way to remedy the leaf curl of Euonymus japonicus?

There are generally four situations in which this problem occurs: first, you are in a "semi-coma" state before transplanting, so please control watering (as long as the soil has a certain humidity) and give the injured root a chance to heal and breathe. Too much watering will lead to root rot; Shading should be done well to avoid the curling of dead leaves caused by excessive water loss of branches and leaves under the condition of unbalanced water supply of plant roots. 2) Don't fertilize the newly transplanted boxwood until its physiological function returns to normal. If fertilizer is applied, it will not only fail to absorb fertilizer, but also induce root rot; Even if it returns to normal, it is not allowed to apply thick fertilizer, but only light and slightly acidic thin fertilizer. So as to avoid leaf curling caused by fertilizer damage. 3) It's winter, although Buxus buxus is resistant to insect pests and low temperature, when the temperature drops to near 0 degrees, it can be wintered outdoors except in the garden, and all kinds of potted plants must be moved to a well-lit place indoors to avoid the potted Buxus buxus from freezing through the pot soil outdoors and dying (any cold-resistant potted plant is afraid of freezing through the pot soil and dying in the early stage). 4) Potted plants, boxwood and other flowers that have been moved indoors for the winter are dormant. Because of the weak light and small evaporation, they don't need fertilization or frequent watering, as long as the basin soil is wet. If the fertility is too high and the basin soil is too wet, it is easy to suffocate the root system and present a dead leaf state. If this happens, please loosen the soil immediately, and install a 100- 150W incandescent light bulb with a reflector on it, and irradiate it continuously for three days and six hours, so as to increase the evaporation of Buxus buxus and promote the cycle of plants (the light bulb is soft, so it is not necessary to avoid leaf curling). ~ ~ ~ Because we can't see the specific situation, we provide the above four items, please refer to the corresponding measures.
