PLANTING and AFTERCARE GUIDE
Best Planting Time
Spring: The ideal time to plant Euphorbia is in spring, allowing the roots to establish well ahead of the growing season for strong, healthy development.
Autumn: Planting in early autumn is another suitable option, giving the plant time to settle before new growth begins in spring.
Site Selection
Sunlight: Euphorbia thrives in full sun to partial shade. Select a location with good light exposure to enhance the rich colouring of its foliage and to encourage vibrant bracts.
Soil: Free-draining soil is essential for Euphorbia ‘Ruby Glow’. It performs best in fertile but well-aerated ground. If your soil is heavy, enrich it with grit or organic matter to improve drainage and structure.
Planting Instructions
Prepare the Hole: Dig a hole twice the width of the root ball and the same depth. This gives Euphorbia ample room to establish its root system.
Soil Preparation: Mix compost or well-rotted organic matter into the removed soil to boost fertility and drainage.
Planting: Position the plant so the top of the root ball sits level with the surrounding soil. Backfill gently, firming as you go to eliminate air pockets.
Watering After Planting: Give your Euphorbia a thorough watering to help the soil settle around the roots. Ensure the area drains freely to avoid waterlogging.
Watering Requirements
Growing Season: Once established, Euphorbia ‘Ruby Glow’ is naturally drought-tolerant. Water during prolonged dry spells only, allowing the soil to dry between waterings.
Dormant Season: Reduce watering significantly. Euphorbias require minimal moisture when not actively growing.
Feeding
Spring: Apply a balanced fertiliser in early spring to support strong new growth and encourage an abundant display of bracts.
Mid-Summer: A light feed in mid-summer helps maintain vigour and colour intensity.
Pruning
Deadheading: Remove spent flower bracts to keep Euphorbia ‘Ruby Glow’ tidy and encourage a neat form.
Seasonal Tidying: After flowering has finished, cut back the stems that have bloomed, taking care to avoid contact with the milky sap, which can be an irritant.
Mulching
Spring: Add a layer of mulch around the base of Euphorbia to regulate soil temperature, reduce weeds, and retain moisture.
Winter: A winter mulch helps protect the plant’s root system and stabilises soil conditions through the colder months.
Supporting the Plant
Euphorbia ‘Ruby Glow’ forms a naturally compact, sturdy mound, so staking is rarely needed. It generally holds its shape well, even in more exposed positions.
Final Tips
Euphorbia ‘Ruby Glow’ is a striking evergreen perennial that provides year-round interest with minimal maintenance. Plant it in full sun or partial shade with free-draining soil, and follow this simple care routine to enjoy vibrant foliage and stunning bracts from spring into summer. This versatile plant adds structure, colour, and contrast to borders and containers throughout the seasons.

Great looking plants – I got a 6 Euphorbia deal and they all arrived as excellent, bushy specimens. Another really good experience with Procters
