Everything has been shooting up in the garden over the last 2 weeks. I
know it's not the optimum time, but is it still OK to do some dividing
and/or replanting of small shrubs and border plants?

We have had a lot of rain last week, with more to come, so the soil is
nice and damp. Last night I thinned out the borders in a couple of
places and replanted where I have gaps. Will they "take"?
