spirea

Spirea (Spiraea Vanhouttei) should be watered moderately on a regular basis to ensure its optimum health and growth. Watering will depend on the plant's location and the soil and climate around it. In general, during hot summer months, spirea should be watered every 3 - 5 days, while in cooler months watering can be reduced to every 5 - 10 days or so. When watering your spirea, make sure the soil is moist but not overly wet, and do not let the soil dry out completely. In addition to frequent watering, be sure to mulch around the base of the plant to help retain moisture.

Spirea (Spiraea vanhouttei) prefers full sun to partial shade. It should receive 6 to 8 hours of sunlight each day in the spring and summer months. It does not do well with more than 8 hours of full sun, so it needs to be shielded from direct sunlight in very hot climates. In fall and winter, spirea can receive 4 to 6 hours of sun per day.

Spirea (Spiraea vanhouttei) should be pruned in early spring, before buds break open and new growth appears. Pruning should be done lightly, trimming the stems back by no more than 1 third of their length. This is to encourage strong, fresh growth while maintaining the desired size and shape of the shrub. Always make sure to remove dead, diseased or damaged stems to promote a healthy plant. Pruning this species requires little effort if done annually, but more involved or severe pruning may be necessary on an as needed basis depending on the specific conditions.
