Japanese spirea

Water Japanese spirea (Spiraea japonica 'Limemound') when the soil feels dry to the touch, and water deeply. In general, expect to water it every 4 to 7 days in the hotter months, then less frequently in the cooler months. When it's really hot out, you may need to water it every couple of days. Make sure not to overwater; if the soil feels wet or soggy, cut back on the amount of water given. The goal is to saturate the soil but not make it overly wet.

Japanese Spirea (Spiraea japonica 'Limemound') prefers to be planted in full sun, meaning it needs a minimum of 6 hours of direct sunlight each day. Early-morning and late-afternoon sunlight is the most beneficial for this plant species. If the sun is blocked by trees or tall buildings, the plant may not be able to thrive in that environment. It is important to be aware of the changing sunlight patterns as the seasons shift, so that the Spirea is able to get the light it needs.

Japanese spirea (Spiraea japonica 'Limemound') should be pruned in late fall or winter when the plant is dormant. This is the best time for pruning as the new growth from pruning will be clearly visible in the spring. Prune the plant by removing any dead or damaged branches as well as removing up to 1-third of the oldest canes to the ground, as these are often less vigorous than new canes. Pay special attention to the center of the plant, as crowded canes in this area can inhibit proper airflow and lead to disease. Lastly, selectively thin out any overly dense parts of the plant to maintain its graceful, arching shape or to encourage healthy growth.
