Last year I bought 12 or 24 mini lavender plugs. I nursed them on, potted on a couple of times (they were in an unheated greenhouse) then I potted into 1 litre pots and put them outside.
3/4 are now dead. When I was putting them on the compost pile today, it's clear they didn't grow on from their last potting on.
Should I have used gritty compost ? I'm wondering if they sat in water.... I leave in East Anglia so a lot of rain compared to other places.
I'm tempted to buy another dozen but I don't want to be a serial killer of lavender !
