I solved that pesky rebloom problem. I just dug them all up.
Sigh. Now I have to replant them.
Irises all gone. I've removed 5 wheelbarrow loads of dirt. Then I put the boards all around the inside of the raised bed. That protects the rubber liner from the tines of my rototiller. I break it up with the shovel and rototill it well and then add fertilizer and compost.
Here's my Mantis tiller mixing the compost and fertilizer into the soil
After it's all done, I mix some of the soil that I removed with compost and fertilizer and fill the bed to the top.
This year I have been compacting the beds some after I am done and before I plant.
