These hardy bulbs are perfect for naturalising in grass, rockeries, or containers, and their compact size makes them ideal for the front of borders or window boxes. Providing an early source of nectar for pollinators, these reliable plants return year after year. For best results, plant in well-drained soil in full sun or semi-shade during the autumn at a depth of 10cm. Once flowering has finished, allow the foliage to die back naturally to ensure the bulbs store energy for the following season. Each pack contains 8 bulbs, making them easy to group together for a carpet-like effect under trees or shrubs.

FAQs
When is the best time to plant Crocus Vanguard bulbs?
These bulbs should be planted in the autumn, ideally between September and November, before the ground freezes.
Can I grow these in pots?
Yes, they are excellent for containers and window boxes. Ensure the container has drainage holes.
How deep should I plant the bulbs?
Plant the bulbs at a depth of approximately 10cm.
Should I feed the bulbs after they flower?
Generally, it is not required. Ensuring the foliage dies back naturally is the most effective way to help the bulb store energy.
Will these bulbs spread over time?
Yes, when planted in suitable conditions, crocus will naturalize and slowly spread to create larger drifts.
Do I need to dig them up every year?
No, Crocus Vanguard are hardy perennials and can be left in the ground year-round.
Troubleshooting
Bulbs failing to sprout in spring
Check if the soil was too waterlogged during winter, causing the bulbs to rot. Ensure future plantings have better drainage.
Flowers appearing stunted or small
This often occurs if the bulbs did not receive enough sunlight the previous spring or if the foliage was cut back too early the previous year.
Squirrels or rodents eating bulbs
Place a piece of wire mesh over the planting area until the soil hardens, or plant bulbs deeper if the issue persists.

Setup, Compatibility & Care
Planting Timing: Bulbs should be planted in the autumn while the soil is still workable.
Depth and Spacing: Plant each bulb at a depth of 10cm. Space them approximately 5-8cm apart for a dense carpet effect.
Soil Requirements: Ensure the planting site features well-drained soil. If your garden has heavy clay, add horticultural grit to the planting hole to prevent waterlogging.
Sunlight: These crocus thrive in full sun but will also perform well in semi-shade conditions, such as under the canopy of trees or shrubs that have not yet fully leafed out.
Aftercare: Avoid mowing the grass where crocus are naturalized until the leaves have completely withered. Fertilizers are generally unnecessary if the bulbs are planted in fertile, well-drained soil.
