PLANTING and AFTERCARE GUIDE
Best Planting Time
Spring: The ideal time to plant Euphorbia griffithii ‘Fireglow’ is in spring when the soil begins to warm. This ensures the roots establish well ahead of the active growing season.
Autumn: Alternatively, plant in early autumn to allow the plant to settle in before dormancy, ensuring vigorous growth the following spring.
Site Selection
Sunlight: Euphorbia griffithii ‘Fireglow’ performs best in partial shade to full sun. Choose a site where the plant will receive dappled sunlight or at least 4-6 hours of direct light daily.
Soil: Ensure the soil is free-draining to prevent waterlogging, which can harm the roots. Adding organic matter such as compost will improve fertility and drainage, creating ideal conditions for Euphorbia griffithii ‘Fireglow.’
Planting Instructions
Prepare the Hole: Dig a hole twice as wide and as deep as the plant’s root ball to give the roots ample room to spread.
Soil Preparation: Incorporate organic compost or well-rotted manure into the soil to enhance its structure and nutrient content. Euphorbia thrives in nutrient-rich, moist, yet well-draining soil.
Positioning the Plant: Place your Euphorbia in the prepared hole with the top of the root ball level with the surrounding soil. Backfill gently, firming the soil to eliminate air pockets.
Watering After Planting: Water thoroughly after planting to help the soil settle and ensure the roots are well-hydrated.
Watering Requirements
Growing Season: Euphorbia griffithii ‘Fireglow’ appreciates consistent moisture but does not tolerate soggy soil. Water during dry spells, allowing the soil to dry slightly between sessions.
Dormant Season: Reduce watering during dormancy. Provide minimal moisture only if the soil becomes excessively dry.
Feeding
Spring: In early spring, apply a balanced fertiliser to support new growth and promote vibrant bracts and foliage.
Summer: A second feeding in midsummer will encourage sustained growth and keep Euphorbia griffithii ‘Fireglow’ healthy throughout the growing season.
Pruning
Deadheading: Remove spent flowers and bracts to maintain the plant’s appearance and redirect energy into root and foliage growth.
Autumn Pruning: After the plant’s foliage has turned, cut back stems to ground level to prepare Euphorbia griffithii ‘Fireglow’ for dormancy and ensure healthy regrowth in spring.
Mulching
Spring Mulch: Apply a layer of organic mulch, such as bark chips or compost, around the base of Euphorbia griffithii ‘Fireglow’ in spring. This will retain soil moisture, suppress weeds, and regulate soil temperature.
Winter Protection: Add mulch in winter to insulate the roots against colder temperatures and reduce the risk of frost damage.
Cautionary Notes
Toxicity: Euphorbia griffithii ‘Fireglow’ contains sap that can irritate the skin and eyes. Always wear gloves when handling this plant, and keep it out of reach of children and pets.
