For new plantings
1. Dig a hole one and a half times wider than the plant's container
2. Place plant in hole, keeping the top of the root ball ground level
3. Back fill with dirt
4. Water thoroughly and then mulch around the base to conserve moisture and reduce weeds
New plantings require more frequent watering than established plants. Wind, temperature and soil are factors to consider in watering.
Feed plants in early spring and again in early fall with an all-purpose fertilizer, following label instructions.
Care Instructions
Spirea plants are easy to care for, making them a popular choice for gardens. To keep them healthy, ensure they receive plenty of sunlight. Water only when the soil is dry, as overwatering can lead to root rot. Fertilize in the spring to encourage growth and flowering. Deadhead spent blooms to promote continued blooming, and prune in the late winter or early spring to maintain their shape. Watch for pests such as spider mites and aphids and treat accordingly. With proper care, spirea plants can thrive and add beauty to any garden.
