Japanese spirea

Japanese spirea plants require regular watering during the growing season (spring to fall). Water thoroughly when the top 1 inch of soil is dry, providing about 1 inch of water each time. Water should be allowed to penetrate the soil and drain freely. During periods of drought or high temperatures, additional water may be required. In winter, reduce watering to once every 2 weeks or as necessary.

Japanese Spirea (Spiraea japonica 'Bumalda') should be placed in an area with full sun or partial sun for optimum growth and blooming. For full sun, the plant should be exposed to at least 6 hours of direct sunlight per day. For partial sun, the plant should be exposed to 3 to 6 hours of direct sunlight per day. The Japanese Spirea is an adaptable plant and can also tolerate partial shade, but will likely flower less in a shadier area. It is best to provide direct light early in the morning and later in the afternoon. Too much direct sunlight in the middle of the day can burn the plant's leaves. When grown in optimal conditions, the Japanese Spirea will flower in the summer months.

Japanese Spirea (Spiraea japonica 'Bumalda') should be pruned annually during the spring season, once the last frost has passed. Pruning helps stimulate new growth and blooms, and usually should not be done prior to the last frost. It is best to prune back 1-third to 1-half of the stems to ground level - removing all branches several inches below the desired shape. Be sure to remove any dead, diseased, or broken branches. Pruning should be done with sharp shears or hedge clippers, and always observe safety practices when using them.
