euonymus

Water euonymus (Euonymus japonicus) plants weekly or every other week throughout the spring, summer and fall when there is no rainfall. Water the plants twice a month in the winter. The amount of water that should be given each time should be enough to soak the soil around the base of the plant and allow water to run through it. Water thoroughly until the soil is saturated and excess water starts to drip from the pot or planter. Let any excess drip off before removing the plant from its pot or planter.

Euonymus japonicus, native to China and Japan, thrives in partial to full sunlight. For optimal growth, the plant should receive at least 4 hours of direct sunlight per day, particularly during the warmer months. The best time of day for E. japonicus to receive sunlight is between 9am and 2pm, when the sun is highest in the sky and provides the most intense light. During this time, the euonymus should be placed in an area with some exposure to direct sunlight, but never in a place where the intensity will be too great and cause burning. During the summer, when the sun is more powerful and the days are longer, the plant may benefit from additional hours of direct sunlight, up to as much as 6 hours per day. In winter, however, the plant should be kept in an area of indirect sunlight with no more than 4 hours of exposure per day.

Euonymus japonicus, also known as Japanese Euonymus, usually requires pruning twice a year in order to maintain its desired shape and size. Prune in late winter or early spring, before new growth begins, to remove any dead, diseased, or overgrown branches. Follow up with another pruning in late summer after flowering has finished. For unusually large or overgrown specimens, additional pruning during the growing season may be necessary to maintain shape. When pruning, thin out or remove any branches that cross over each other, as well as any old-wood branches that produce few, if any, leaves. When shaping, use pruning shears to make clean, sharp cuts close to the junction of the branch and the trunk, and avoid excessive pruning.
