Product Information
Full details
The Iris reticulata 'Cantab' is ideal for gardeners looking to bring early-season interest to small spaces or rockeries. Its primary benefit is the early arrival of vibrant, sky-blue flowers that signal the end of winter, though potential growers should note that these bulbs require well-draining soil to prevent rot during dormant months. This pack of 20 bulbs is perfect for naturalizing or creating dense, colorful displays in containers.

FAQs
When is the best time to plant Iris reticulata 'Cantab'?
These bulbs should be planted in the autumn, ideally before the first hard frost, to allow them time to establish roots before winter.
Can I grow these in pots?
Yes, they are excellent for containers and window boxes. Just ensure the pot has good drainage and use a potting mix with added grit.
Do I need to dig them up after they bloom?
No, they are hardy perennials and can be left in the ground to naturalize, provided the soil drainage remains good throughout the year.
Will they survive a harsh winter?
Iris reticulata is very cold-hardy and is designed to bloom through the tail end of winter and early spring conditions.
What should I do with the foliage after flowering?
Leave the foliage alone until it turns yellow and dies back completely. This ensures the bulb can store energy for the next growing season.
Are these deer or rodent resistant?
While generally not the first choice for deer, like most bulbs, they can be attractive to squirrels; using a bulb cage or hardware cloth can provide extra protection.
Troubleshooting
Bulbs failing to emerge in spring
Likely due to winter waterlogging; ensure planting site has excellent drainage or raise the soil level.
Foliage appears but no flowers
This often occurs if the bulbs did not receive enough sunlight the previous year or if they are planted too deeply.
Leaves turning yellow too quickly
Check for signs of pests or ensure the soil hasn't dried out completely during the brief growing window.
Pros and Cons
Pros

Setup, Compatibility & Care
For the best results, plant the bulbs at a depth of roughly 8-10cm in a location that receives full sun. If your soil is heavy or prone to clay, incorporate horticultural grit or sharp sand into the planting hole to improve drainage. After flowering, allow the foliage to yellow and wither naturally before trimming; this step is crucial for the bulb to store enough energy for the following season. Avoid heavy mulching that could trap moisture around the neck of the bulb, as this is the most common cause of failure in 'Cantab' irises.
