Cool and shady
The most important rules to bear in mind when growing snowdrops indoors is that they should be kept cool and shaded, as too much heat can cause your bulbs to ‘go blind’ (fail to develop flower buds). For optimum conditions, they should ideally be kept on a North-facing windowsill.
It’s also essential that you don’t allow your soil to dry out – although don’t get it too wet as this can rot the bulbs. Snowdrops need a period of prolonged exposure to the cold in order to thrive, so whenever you choose to plant your bulbs, they will always begin to develop just after the winter.
Planting your bulbs
When potting your bulbs, ensure your container has a drainage hole at the bottom, and that the tops of the bulbs are about an inch from the surface of the soil.
Place a saucer under the container and add water until it begins to drip through the drainage hole. After about an hour, pour away the water from the saucer.
Keep them happy
Once potted and watered, keep them in your cool, shady spot until January, when they can be brought out into the winter sunshine. But as the spring approaches, ensure they are returned to the shade, away from excess light and heat.
After flowering season
Once your flowers have finished blooming, you will be left with a green plant that should last until late June. The green shoots will be photosynthesizing food to help the snowdrop bulb develop for the next year's growth, so allow the shoots to die back naturally – don’t be tempted to cut them back!
