PLANTING and AFTERCARE GUIDE

Optimal Planting Time

• Spring: Planting Berberis darwinii ‘Compacta’ in spring allows its roots to establish as the soil warms. This helps the shrub grow robustly before the arrival of cooler months.
• Autumn: Autumn planting is also effective, as the soil’s residual warmth promotes root development before the plant enters dormancy.

Choosing the Perfect Site

• Sunlight: Berberis darwinii ‘Compacta’ flourishes in full sun to partial shade. It thrives in locations that receive at least 4–6 hours of sunlight daily but adapts well to slightly shaded areas.
• Soil: This hardy shrub prefers well-drained soil. While it tolerates a range of soil types, incorporating organic matter ensures optimal drainage and nutrient availability. Avoid waterlogged conditions to prevent root issues.

Planting Instructions

1. Prepare the Ground: Dig a hole twice as wide and the same depth as the root ball to give the roots ample room to spread.
2. Improve the Soil: Mix compost or well-rotted organic material with the excavated soil. This enhances drainage and provides essential nutrients.
3. Position the Shrub: Place Berberis darwinii ‘Compacta’ in the hole, ensuring the top of the root ball sits level with the ground. Backfill the hole, firming the soil gently to eliminate air pockets.
4. Watering: After planting, water the shrub thoroughly to settle the soil around the roots and aid establishment.

Watering Requirements

• Establishment Period: During its first year, Berberis darwinii ‘Compacta’ requires consistent watering to establish its roots. Ensure the soil remains moist but not soggy.
• Drought Tolerance: Once established, this hardy shrub is moderately drought-tolerant. Water during prolonged dry periods but allow the soil to dry slightly between watering sessions.

Feeding

• Spring: Apply a balanced, slow-release fertiliser in early spring to support new growth and vibrant flowering.
• Summer: Supplement with a light feed during mid-summer to maintain the plant’s health and encourage lush foliage.

Pruning and Maintenance

• Light Pruning: In late spring, prune Berberis darwinii ‘Compacta’ lightly to remove spent flowers and promote bushy growth.
• Hard Pruning: Every few years, consider harder pruning in late winter to rejuvenate the plant and maintain its compact shape.

Mulching Tips

• Spring Mulch: Apply a layer of organic mulch, such as bark chips or compost, around the base in spring. This conserves moisture, suppresses weeds, and improves soil structure.
• Winter Protection: While Berberis darwinii ‘Compacta’ is hardy, mulching in late autumn can insulate roots during severe cold spells.

Support

• This compact variety typically requires no staking, as its dense growth habit and sturdy stems naturally resist wind damage.
