My garden in Sheffield is also reaaaaaally behind where it was last year. I would guess about 3 even maybe 4 weeks. I am bursting with impatience for the lovely late spring plants!
However, my Dad's garden in East Anglia is firing on all cylinders. I am normally about 7-10 days behind him, but this year the lag is much greater than normal.
I'm wondering if this is because we had a very harsh winter here (lots and lots of lying snow for a couple of weeks), whereas they have had a relatively mild one?
Anyone else noticing a lag?
