Planting Ilex crenata 'Caroline Upright'

Location and Soil

• Location: Choose a spot with full sun to partial shade. This shrub performs best in a location where it receives morning sun and afternoon shade, especially in hotter climates.
• Soil Preparation: Ensure the soil is well-drained and rich in organic matter. Ilex crenata 'Caroline Upright' tolerates a range of soil types but thrives in slightly acidic to neutral pH.

Planting Instructions

• Planting Depth: Dig a hole that is twice as wide and as deep as the root ball. Position the plant so that the top of the root ball is level with the surrounding soil surface.
• Spacing: Space plants 1.2 to 1.8 meters (4 to 6 feet) apart if planting as a hedge or screen to allow for their mature spread.
• Watering: Water thoroughly after planting and keep the soil consistently moist but not waterlogged. Regular watering is crucial during the first growing season to establish a strong root system.

Maintenance Tips for Ilex crenata 'Caroline Upright'

Regular Care

• Watering: Maintain even moisture throughout the growing season. Water deeply during dry periods to encourage a deep root system. Reduce watering frequency in winter but ensure the soil does not dry out completely.
• Fertilizing: Apply a balanced, slow-release fertilizer in early spring before new growth begins. Follow the manufacturer’s recommendations for application rates to promote healthy growth and vibrant foliage.
• Pruning: Prune in late winter or early spring to shape the plant and remove any dead or damaged branches. Regular trimming helps maintain its compact, upright form and encourages dense growth. Light pruning throughout the growing season can help control size and shape.

Seasonal Care

• Spring: In early spring, remove any winter debris and inspect the plant for signs of damage or disease. Apply mulch around the base to conserve moisture and regulate soil temperature.
• Summer: Ensure the plant receives adequate water, especially during hot, dry spells. Monitor for pests and diseases, such as scale insects or leaf spots, and treat as necessary.
• Autumn: Clear fallen leaves and debris from around the plant to prevent fungal infections. The plant may benefit from a light layer of mulch to protect roots during colder months.
• Winter: While Ilex crenata 'Caroline Upright' is generally hardy, provide some protection during severe winter conditions, especially in regions with heavy snowfall or freezing temperatures. A layer of mulch around the base can help insulate roots.
