Setup, Compatibility & Care
To ensure success, plant your 'Wisley Blue' bulbs in autumn when the soil begins to cool. Ensure they are placed in soil that drains freely to avoid waterlogging, which can cause the bulbs to rot. If planting in heavy clay, incorporate grit or sand into the planting hole. Once the flowering period finishes in late spring, allow the foliage to yellow and die back naturally; this process is essential as it feeds energy back into the bulb for the following year. Do not prune the leaves until they have completely withered.
