This autumn I'm planting native English Bluebells in a small Beech wood we have. As I've dug into the subject, it's amazed me how varied the advice is online.
I started with the helpful GreenPlantSwap guide What is a Bluebell? which got me clued up on how to differentiate the English from the Spanish and Hybrid variants, which are horribly invasive and strip the English bluebells of their scent. So I took real care in sourcing a credible supplier.
The I looked at the planting. Some people recommend use of an auger (a spiral drill) to make 4-6 inch holes for the bulbs. That certainly sounds quick and easy. However, others recommend against this and say prepare the ground with a mattock to reduce competition from shallow Beech roots and other vegetation and avoid restricting the natural spread of the plants. The latter sounds the wiser course.
The recommended planting density ranges from 20 - 250 bulbs per square metre - a huge variation. No doubt the more you have the more intense the colour and scent will be come the Spring. Or are the higher figures quoted unsubtle sales ploys?
Then many sellers say nothing about the age of their bulbs; while others say you need mature bulbs at least 4 years older to be assured of flowers the following season. I've gone with a seller who claims their bulbs are 5-6 year old mature Bluebells.
I'd welcome any views and personal experience people have on these points.
