All my rosemary plants keep dying. I've been trying to grow them for years.
The leaves turn yellow, drop off and the plant looks awful and I end up by throwing it out.
I've tried sunny positions, shaded, partial shade, in pots, in the garden, plenty of water, not so much water, dry. I've tried looking after them and neglecting them. South facing garden and a northwest garden.
They all die!
What am I doing wrong?
