How to Grow Bluebells

Bluebells make a lovely carpet of blue, especially in a woodland setting, and are a quintessentially British woodland flower. In fact, about half the bluebells in the world grow in the UK and they are a very popular plant. 

 In the right conditions, Bluebells grow themselves.

Bluebells carry a gardening warning that they can be invasive. Bluebells can take a little while to get established, but once established, they can out-compete other plants and take over. In good growing conditions, Bluebells are vigorous and become hard to eradicate, so take care where you plant them. In some conditions, they can be considered weeds. If you consider the sorts of places where Bluebells are admired and look at their best, it is in a wild, or semi wild setting with lots of room such as a woodland. Most gardens are not large enough to accommodate a woodland area, and a good alternative to Bluebells, which is less invasive, is the spring flowering bulb Camassia. Although flowering a little later, late April onwards, it is far better behaved and more suited to smaller spaces.

It is important from the conservation perspective to  buy and plant only English Bluebells. There is an impostor, Illustrated below which is the Spanish bluebell. It is even more vigorous than the English variety, (if anything could be) and the natural movement of pollen by bees will cross pollinate with the English variety to contaminate the strain. This will threaten the purity and longevity of the English bluebell, which is a more delicate, attractive flower. By checking you buy and plant only English bluebells, you ensure our native species cannot be out competed by the Spanish variety.

How and Where to Plant Bluebells

Bluebells are a woodland plant, so the ideal growing conditions are those which they would enjoy in woodlands. Bluebells grow and flower well in part sun and part shade conditions, in soil which is moist and which does not dry out during the summer.  

Bluebells can be planted in the spring as ready plants, or more economically as bulbs in the Autumn. If planting Bluebells in the green in the spring, which is as garden ready plants,  Bluebells should be planted at a depth so the soil is at the same level, which means all the white part of the stem is buried underground.

If planting in the autumn as bulbs, plant around 10cms deep, pointed end uppermost This will be about 3 times the depth of the bulb and it is important to water well after planting. (How to plant spring bulbs.)

Only plant Bluebells where there is a good sized area which they can colonise without spoiling the garden and becoming a pest plant. 

This means plant Bluebells in a large area where they will not impinge on other plants.

If Bluebells are taking over, the only way to eradicate them is to dig them out, weedkillers are not found to be very effective.  Dig out when the Bluebells are in bloom, so you can dig down and locate the bulb. It is also best not to compost the bulbs.
