watering
Water Japanese kerria (Kerria japonica 'Pleniflora') once every 5-7 days, providing enough water to keep the soil evenly moist throughout the root zone. During periods of prolonged hot weather, water slightly more often to ensure that the soil does not dry out. Avoid overwatering, as this can cause root rot.
sunlight
Japanese kerria (Kerria japonica 'Pleniflora') should be grown in an area with partial shade or dappled sunlight. This plant prefers morning sun and afternoon shade, so it should receive at least 4 to 5 hours of direct sunlight each day. If the plant is located in an area that is too sunny, it may become stressed and develop yellow foliage. It should be protected from direct, hot afternoon sun and wind.
pruning
Japanese kerria should be pruned for both rejuvenation and to maintain a desired shape. Generally, pruning should take place in late winter or early spring, around February or March, when new growth has yet to appear. However, if the plant is already beginning to flower, wait until blooming has finished to do most of the pruning. When it comes to pruning Japanese kerria, the idea is to remove dead, diseased, and damaged wood and thin out overgrown stems. Lightly shape the shrub by cutting back the longest, overreaching branches. Do not cut into the green wood that still has leaves as this will create more work as more heads will form. Prune out any crossed branches, sharp angles, and suckers (offshoots from the rootstock). If needed, you can also prune out up to 1 third of the overall plant, leaving the healthy ones. It is best to avoid pruning any more than 1-third of the plant at once.
