my lavender bushes have grown a bit straggly. i know the advice is to trim them all over in autumn, but only the new season's growth. i did that last autumn, to the older bushes, but over the winter there has been some dieback of the new growth even on the untrimmed bushes, and there is lots of dead material in the middle of the bushes, and there old dead branches that died the previous winder. this gets all soggy when it's wet, and i can't imagine that the lavender is happy, although they seem perky when the sun shines. so today, in the rain, i cut back most of the dead wood, even quite thick branches, and trimmed out the new growth that had died back, and gave them all a haircut all over. i hope they survive! did i do the wrong thing? does anyone else do this?
