PLANTING AND AFTERCARE GUIDE
Best Planting Time
Spring: Plant Geranium ‘Joseph Green’ in early spring when the soil is warming up. This allows strong root establishment before the blooming period.
Autumn: Alternatively, plant in early autumn, giving the roots time to settle before dormancy, ensuring vigorous growth in the following season.
Site Selection
Sunlight: Geranium ‘Joseph Green’ thrives in full sun to partial shade. A minimum of 4–6 hours of sunlight daily encourages healthy growth and flowering.
Soil: Well-drained, fertile soil is essential. Improve heavy or compacted soil by adding compost or organic matter to enhance drainage and aeration.
Planting Instructions
Prepare the Soil: Loosen the planting area and enrich it with compost to improve structure and nutrient content.
Dig a Hole: Make a hole twice the width and the same depth as the root ball.
Position the Plant: Place Geranium ‘Joseph Green’ in the hole, ensuring the crown sits level with the soil surface.
Backfill & Firm the Soil: Gently fill the hole and press down to eliminate air pockets.
Watering: Water thoroughly after planting to help the roots establish.
Watering Requirements
During Growth: Keep soil consistently moist but avoid waterlogging. Water deeply once a week, adjusting during dry spells.
Dormant Season: Reduce watering in autumn and winter to prevent root rot.
Feeding
Apply a balanced, slow-release fertiliser in early spring to encourage strong growth.
A liquid feed in late spring can boost flowering performance.
Pruning & Maintenance
Deadheading: Remove spent blooms to prolong the flowering period and keep Geranium ‘Joseph Green’ looking fresh.
Cutting Back: After flowering, trim back leggy stems to promote bushy growth.
Winter Care: In colder months, cut back foliage to ground level to encourage healthy regrowth in spring.
Mulching
Spring: Apply a layer of mulch around the base to retain moisture and suppress weeds.
Winter: A thicker mulch layer can help insulate the roots from frost.
Supporting the Plant
Geranium ‘Joseph Green’ has a naturally compact growth habit and usually does not require staking. However, in exposed areas, light support may be beneficial.
