I mean, could have been the fertilizer, or could have just been an insulating layer?

- zdragnar 2y agoSince OP mentioned both with and without the mulch got fertilizer, it's definitely insulation. They also mentioned "bad dirt" as well, so there's a very good chance the mulch also helped with moisture retention.
- abakker 2y agoyeah, we have alkaline expansive clay, so moisture retention was an objective. I added the nitrogen to offset the fact that fresh wood chips tend to be a nitrogen sink rather than a source. I theorize that thermal protection and moisture retention together have kept those plants happier.
- x______________ 2y agoNutritional "thermal protection and moisture retention" given that you've also added fertilizer. As a side topic to the original post, do you have any comparison pictures to support the topic and theory? I'd be interesting to see your progress!
