They did fine, watering was a little tricky, when the compost shrinks away from the fabric water can end up running down the sides and not wetting the roots. When I get them all upsized and can run the drip tape inside the fabric that shouldn’t be a problem.
I shift them 90 degrees and combine rows, they end up looking like this, only one layer for larger trees.
I settled on empty 10/20 flats to create an airspace between layers of groundcover fabric, have plenty of them to use.
