Building a series of raised beds for a new garden using 2x12 rough cut heart redwood. I treat with tung oil in a sprayer diluted with mineral spirits, use 4” deck screws at the corners plus titebond 3 glue, hardware cloth bottoms and raise off the ground with river rock. I fill the space underneath and half bed depth with mulch/loam mix and top with organic bedding soil. The bed in the photos is 3’x11’.

Transplanted as dormant bareroot approximately two months ago, budded and leafed just fine initially. Some browning on a few leaves and dead/limp new growth. What is going on?
