Japanese kerria

Japanese kerria should be watered once weekly, enough to keep the soil lightly moist but not wet. Watering needs may vary depending on the season, as plants may need more frequent watering in the warmer months and less in the cooler months. It is important to always check soil before watering; if the top inch is dry, it is time to water. Japanese kerria may also benefit from occasional misting to keep its foliage hydrated on hot summer days.

Japanese kerria (Kerria japonica 'Golden Guinea') prefers full to partial sun in order to thrive. It should receive at least 4 hours of direct sunlight every day, but will also tolerate some light shade. In areas with very hot summers, providing partial shade in the afternoon may be beneficial. This plant should not be exposed to full shade for extended periods of time, as this can lead to reduced flowering or even death of the plant.

Kerria japonica 'Golden Guinea' should generally be pruned from late winter to early spring. Prune lightly to maintain the shrub's natural growth habit, removing just a few of the oldest stems close to ground level. Remove any crossing or dead branches at this time as well. In subsequent years, decide to either light pruning or rejuvenation pruning. For light pruning, prune just a few branches at a time to maintain a compact bushy shape. Prune no more than 1-third of the shrub. For rejuvenation pruning, cut the entire shrub back by 2-thirds or more of its original size. Doing this every 3-5 years will help keep the Kerria japonica 'Golden Guinea' looking vibrant and healthy.
