Hi MN gardening gurus. :)
I am very much a beginner gardener. We have just moved to a house that actually - gasp - has a garden!!!!! I am SO excited.
However, we have a row of about 7 large lavendar bushes that have not been pruned or shaped for years. They originally were in balls i think. They have hugely long dead stems towering into the air, and about 30 cm below that fresh leaves. I want to prune the dead stems right down, and prune (hack) the fresh stems right back as well, but a friend told me that if I prune at the wrong time, then i will just kill the plants.
I feel pretty sure the dead stems can go, but if i take the current bushes down by about 50%, would that be too drastic? When should I do that if not now?
Any help and advice gratefully received!
