Lost my big lime tree a few weeks ago. Death in the family and it didn’t get watered in all the resulting chaos. I’m going to try to get a cutting from one of the rootings I’ve given away over the years.
Thanks for the links, I check them out more tomorrow. I’m about out of steam for the day. Going to go to bed soon, I think.
Sorry to hear about your loss. That’s always hard. Lost my dad a couple of years ago and I think about him every day.
