Lavender!!! Help me

[stevalnamechanger]

I bought 3 x expensive lavender from a lavender farm a few weeks ago all dead

Bought several cheap ones from Morrisons 2/3 dead

I assume it's from excess rain , it was reported in the right soil with Grit but something is going wrong 😭😭😭

Any wizards able to assist ?

I have a french lavender from Lidl that thrives in a zinc planter with gravelly, rubbish soil, not fed, occasionally watered. Has survived frosty winters and is flowering nicely now. Full sun, front of house, in gravel for English lavender, jus cut back hard after flowering every year, also thriving. Ignore them, put them in crap, gritty soil.
