I meant to post this when I received my 100 busy lizzy plugs three weeks
ago.

Last year I got them at the same time and planted them in 3 inch pots in
mult pupose with a little slow release (as I have done this year), and they
just sat there for weeks on end and never moved. It was well into summer
before some of them eventualy grew away healthily and spectaculalry whilst a
few just withereds up and died.

Looks like the same things happening this year. Where am I going wrong.

There in a bubble wrap insulated greenhouse which is frost free.

Have recently adjusted night temperature to nearer 5-7C to see if that
helps.
