FAQs
Please read our FAQs page to find out more.
What's the best compost for my flower bulbs?
We would recommend a compost that contains nutrients that last up to 6 months to promote strong, healthy roots, and often includes a wetting agent to improve water retention and drainage for a vibrant spring display.
Here's the perfect one: Click Here
How can I prevent my bulbs from rotting and ensure they bloom again?
Bulbs rot in wet soil! You must have light, well-drained soil. Work compost or organic matter 8-12 inches deep into the planting bed to ensure rapid drainage and aeration.
Plant most bulbs in full sun or part sun for the long-term energy recharge.
What is the most critical step for getting flowers next year after the current blooms fade?
Do not cut the foliage (leaves) after the flower dies. The green leaves need approximately 8 weeks to yellow and brown naturally. This post-bloom period is when the bulb recharges its energy (carbohydrates) for next year’s flower. Cutting them early causes bloom failure!
How deep should I plant my bulbs?
Plant bulbs roughly three times as deep as the bulb’s height (e.g., a 2-inch tall bulb should be planted 6 inches deep). This depth provides crucial thermal protection.
You'll find the exact specifications on the bulbs page/
Do you ship to Northern Ireland or the EU?
At present, we’re unable to ship to Northern Ireland due to post-Brexit regulations. The additional paperwork and costs involved would make it too expensive for customers.
We hope this situation will change in the near future.
