Planting Instructions
|
- Best Time to Plant: Early spring or fall, allowing the shrub to establish roots before extreme weather conditions.
Planting Instructions:- Soil Requirements: Prefers well-drained soil with slightly acidic to neutral pH. Adaptable to a variety of soil types, including sandy, loamy, or clay soils.
- Spacing: Space plants 2-3 feet apart to allow for mature growth and air circulation.
- Depth: Plant at the same depth as the root ball, ensuring the crown is level with the soil surface.
|
Pruning & Maintenance
|
- Pruning Needs: Prune in late winter or early spring to remove dead or damaged branches and maintain a neat, rounded shape. Light pruning after flowering can encourage a second, smaller flush of blooms.
- Winter Care: Empire™ Ice Dragon is cold-hardy and does not require special winter care. Its dense branches and bright foliage provide interest throughout the year.
|
Water Needs
|
- Watering Frequency: Water regularly during the first growing season to establish a deep root system. Once established, it is moderately drought-tolerant and only needs occasional watering during dry periods.
- Drought Tolerance: Performs best with consistent moisture but is moderately drought-tolerant once established.
|
Light Needs
|
Full sun to partial shade. It blooms and grows best in full sun (6+ hours of sunlight per day), but it can tolerate some light shade. |
Harvesting
|
- When to Harvest: Flowers can be harvested when fully open for fresh floral arrangements, or the bright golden fall leaves can be collected for dried arrangements.
- How to Harvest: Use sharp pruning shears to cut stems with flower clusters or colorful fall branches for decorative use.
|
Fertilizing
|
- When to Fertilize: Fertilize in early spring before new growth begins to encourage healthy growth and flowering.
- Type of Fertilizer: Use a balanced, slow-release fertilizer or organic compost to support plant health and improve bloom production.
|
Additional Care Tips
|
- Mulching: Apply a 2-3 inch layer of organic mulch around the base to help retain moisture, regulate soil temperature, and suppress weeds.
- Pests: Generally pest-free but occasionally may attract aphids or spider mites. Use insecticidal soap or neem oil if necessary.
- Disease: Ensure good air circulation to prevent fungal diseases. This variety is resistant to most common spirea diseases.
|
Pollination
|
- Spiraea japonica Empire™ Ice Dragon is pollinated by bees and butterflies. Its white flower clusters are rich in nectar, making them an excellent food source for pollinators during late spring and summer.
