Cutting back lavendar

Good morning everyone. I have a really lovely lavender bush and the bees and butterflies have lived it all summer. It is now past its flowering stage now and I need to cut it back as it has taken over. When should i do this and how severe can/should I be? Thank you!

I followed Monty Don's advice and it seems to work very well. I did mine about a month ago and it is now lovely and bushy again. Cut back quite hard up to where new growth is showing and so it looks nice and tidy. Dont be shy. I thinks its quite difficult to kill lavender or mine would be long gone. Others may have different advice for you and I can only tell you what worked for me. I dont call myself the plant assassin for nothing ha ha.

 

I do exactly as @ThePlantAssassin says cut back after flowering to the lowest new growth. Lavender and Rosemary are among those plants that don't readily produce new growth on old wood. So you cut back to where you can see growth coming already.

 

Thanks both. That’s really useful. No time to waste them....

Cheers.

 

I trimmed one of mine earlier this evening, I'd missed it earlier in the summer.

 

It’s on the list for the weekend. Thanks.
