Wow, Tim those are looking beautiful. How sad that the maggots have started their dirty work, I bet with your care they will send out new roots and be fine.
I had a couple of colonies damaged last month from the maggots. I found them when I dug up the entire bed in preparation to add a new 10" layer of premium mix, bringing the soil level back to the top of the bed.
Alice, it is sure good to see color coming out in your collection.
