PLANTING and AFTERCARE GUIDE
Best Planting Time
Spring: Plant Crocosmia Walbertons Yellow in spring as the soil starts to warm. This allows the corms to establish strong roots before summer flowering.
Autumn: Planting in early autumn gives Crocosmia Walbertons Yellow time to settle before the dormant season, ready for vigorous growth next year.
Site Selection
Sunlight: Crocosmia Walbertons Yellow performs best in full sun but will tolerate part shade, especially in hotter spots.
Soil: Choose moist, well-drained soil, enriched with organic matter. Avoid waterlogged ground, which can cause corms to rot.
Planting Instructions
Prepare the hole: Dig a hole 8–10 cm deep and wide enough for the corms to sit comfortably.
Soil preparation: Mix in compost to improve fertility and drainage.
Positioning: Place Crocosmia Walbertons Yellow corms with the pointed end facing upwards, spacing them 10–15 cm apart.
Backfill and water: Cover with soil, firm gently, and water well to settle the corms.
Watering Requirements
Keep soil evenly moist during the active growing season. Crocosmia Walbertons Yellow benefits from regular watering in dry spells, particularly while in flower.
Reduce watering as the foliage dies back, allowing the corms to rest during dormancy.
Feeding
In early spring, apply a balanced granular fertiliser to encourage healthy leaf growth and flower production.
A liquid feed every 4–6 weeks during summer can help Crocosmia Walbertons Yellow produce more vibrant blooms.
Pruning
Remove spent flower stems to prolong the display and keep the clump looking tidy.
Once the foliage yellows in autumn, cut Crocosmia Walbertons Yellow down to ground level to prepare for the next growing season.
Mulching
Apply a 5 cm layer of organic mulch in spring to conserve soil moisture, suppress weeds, and nourish the soil.
In colder periods, mulch over the planting area to help protect the corms from temperature fluctuations.
Supporting the Plant
While generally self-supporting, Crocosmia Walbertons Yellow may benefit from discreet staking in exposed or windy sites to keep the arching stems upright.
Final Tips
Crocosmia Walbertons Yellow is a low-maintenance, hardy perennial that adds striking colour and structure to summer borders. By planting it in a sunny, well-drained position and following this simple care routine, this Crocosmia will reward you with reliable, glowing blooms year after year.
