Planting Instructions
|
- Best Time to Plant: Early spring or fall is ideal, allowing the plant to establish roots before summer heat or winter cold.
- Soil Requirements: Thrives in well-drained, sandy or rocky soils. 'Youngstown' is adaptable to a wide range of soil types but prefers soil with good drainage.
- Spacing: Space plants 4-6 feet apart to accommodate their spreading habit and ensure proper 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: Minimal pruning is required. Lightly prune in late winter or early spring to maintain shape or remove any dead or damaged branches. It can also be pruned to control size if needed.
- Winter Care: No special winter care is required, as this juniper is highly cold-hardy and can withstand harsh winter conditions.
|
Water Needs
|
- Watering Frequency: Water regularly during the first growing season to establish a deep, extensive root system. Once established, water deeply but infrequently.
- Drought Tolerance: Highly drought-tolerant once established, making it perfect for dry, poor soil conditions.
|
Light Needs
|
- Full sun for best foliage color and density. It can tolerate partial shade, but growth and color may be reduced.
|
Harvesting
|
Though not a harvest crop, Juniperus ‘Plumosa Compacta Youngii’ offers decorative value. |
Fertilizing
|
- When to Fertilize: Fertilize in early spring with a balanced, slow-release fertilizer to encourage healthy growth. Fertilizing is generally unnecessary in well-drained, nutrient-poor soils.
- Type of Fertilizer: Use a general-purpose fertilizer or one formulated for evergreens.
|
Additional Care Tips
|
- Mulching: Apply 2-3 inches of mulch around the base to conserve moisture, suppress weeds, and protect the roots, especially during the first growing season.
- Pests: Generally pest-free, though spider mites and scale insects may occasionally be a problem. Treat with insecticidal soap or neem oil if needed.
- Disease: To avoid fungal diseases such as root rot, ensure good drainage and avoid overwatering. Ensure proper spacing for good air circulation.
|
Pollination
|
- Juniperus horizontalis 'Plumosa Compacta Youngstown' is wind-pollinated, and its flowers are typically not a focal point. Its ornamental value lies in its year-round evergreen foliage and spreading habit.
