This post will tell you how to prune English lavender beautifully.I couldn’t work out why next door’s lavender is still healthy and bushy after fourteen years. Some of my lavender bushes have barely lasted four.Yet I followed all the advice I was given. ‘Never cut lavender back to the wood’ is in every list of gardening dos and don’ts.But now I know that we amateur gardeners often misinterpret that. So we are not cutting our lavender back enough. Let me explain.My lavender in 2013. It was planted in 2010, and the lavender by the obelisk had gone woody and gappy by 2014. It had to be taken out.A neighbour’s lavender – it’s been there for over 14 years and still going strong.The lavender is a major feature in my garden. There are four big clumps around a pot in the centre. At midsummer, it is humming with bees and other pollinating insects.But it started to look gappy and woody. There was also some lavender around the beds and that went completely woody and stalky. It was so ragged that I took it out.
