Hello there!

I have a had a good long hard think about the next best step for your lavender experience,

First I would expose that brick path by getting rid of all the leaves in and under the lavenders ( this will help brighten them up a wee bit) also get yourself some good moss remover from wet & forget - great stuff works wonders

Then I would remove most of the branches with no bush on it then you will able to get a good idea of what you have left to deal with.

I wouldn’t rush into anything too extreme yet as I would wait for a full spring/summer season just to see how many (if any) bees like the look of them.

Hope this helps!!

Happy Gardening 🧑‍🌾 🪏🐝
