I have bought a few lavender plants over the years and they have not lasted very long. I use lavender so I would really like to make this work. My latest plant was doing well, but recently half of it has died off, I was thinking of removing it from the small pot it is in, and placing it in a window box type planter. The planter is currently hanging on my fence underneath a tree so it receives filtered light, mostly early morning sun. Does this sound like a good idea? Anyone have any suggestions. thanks in advance.
