Help! My lavender is turning yellow

[VanillaSugarr]

Last summer I planted some lavender plants behind a box hedge and they limped along all winter. This spring I moved them to a sunnier border but they have turned yellow and don’t look happy.

The soil is heavy clay and I have read that maybe they are suffering from over watering and lack of drainage.

Can I lift them up and put in some sand, then replant them again?

Ironically I also have some lavender in a very shady border and this looks beautiful.

Back to the question - how do you save yellowing lavender?

Many thanks.

I'd dig them up, put them in pots until they are healthy again and then find somewhere better for them. Or just keep in pots and put the pots where you want the plants.

Thanks for your replies. So I do this... repot the lavender, wait until the Autumn, harvest all the veggies and then dig in lots of grit, topsoil and compost so that it over winters?

What sort of grit? Sharp grit or coarse grit?

Thank you!
