PLANTING and AFTERCARE GUIDE
Best Planting Time
Spring: The ideal time to plant Callistemon Citrinus is in spring when the soil has warmed. This ensures the roots establish before the active growing season.
Autumn: Alternatively, plant in early autumn to give the shrub time to settle before dormancy, encouraging vigorous growth the following year.
Site Selection
Sunlight: Callistemon Citrinus thrives in full sun. Choose a location that receives at least 6-8 hours of direct sunlight daily to support vibrant blooms and healthy foliage.
Soil: This shrub prefers well-drained soil. It tolerates a range of soil types but performs best in slightly acidic to neutral soil. Incorporate organic matter like compost to improve drainage and fertility.
Planting Instructions
Prepare the Hole: Dig a hole twice as wide and as deep as the root ball of your Callistemon Citrinus to allow adequate space for root development.
Soil Preparation: Mix compost or well-rotted manure into the excavated soil to boost fertility. Ensure good drainage to prevent waterlogging, which can harm the roots.
Planting: Place the root ball in the hole, ensuring the top sits level with the surrounding soil. Backfill gently, firming the soil as you go to eliminate air pockets.
Watering After Planting: Water thoroughly after planting to settle the soil and help the roots establish.
Watering Requirements
Active Growth: Water Callistemon Citrinus regularly during its first year to help the roots establish. Once mature, it is drought-tolerant but will benefit from watering during prolonged dry spells. Allow the topsoil to dry slightly between watering sessions.
Dormant Season: Reduce watering during winter when the plant is less active, ensuring the soil doesn’t become overly saturated.
Feeding
Spring: In early spring, apply a slow-release fertilizer formulated for acid-loving plants. This provides the nutrients needed for robust growth and vibrant flowers.
Summer: A mid-season application of liquid fertilizer can encourage prolonged blooming and maintain the plant’s vitality.
Pruning
After Flowering: Lightly prune Callistemon Citrinus immediately after flowering to remove spent flower spikes and encourage new growth. This also helps maintain a compact shape.
Annual Maintenance: In late winter or early spring, trim back any dead, damaged, or overcrowded branches to improve airflow and overall plant health.
Mulching
Spring: Apply a layer of mulch around the base of the plant to retain moisture, regulate soil temperature, and suppress weeds. Use organic materials like bark chips or compost.
Winter: A thicker layer of mulch during winter helps insulate the roots from frost and prevents soil erosion.
Supporting the Plant
Staking: While Callistemon Citrinus is generally sturdy, young plants or those in windy locations may benefit from staking to protect against damage.
Additional Care Tips
Pests and Diseases: Callistemon Citrinus is relatively pest-resistant, but keep an eye out for common issues like scale insects or fungal diseases. Address these promptly with appropriate treatments.
Frost Protection: In colder regions, protect young plants with horticultural fleece or move container-grown specimens to a sheltered location during severe frosts.
