Thanks, BZ. It did get drowned by a exploded sprinkler head about 10 days ago. The upper leaves recovered and I was being very careful to only put a quart of fertilizer on the roots at a time. But it would go through over 2 gallons of water a day from the reservoir.

I just got some shade cloth...as soon as I figure out how to rig it up on the patio it will help with those 110 degree days.

Potting soil...used Big Lot's Black Magic (gloried bark) that I amended with lime, coffee grounds, perlite etc. Then I added better quality potting soil with bat guano etc when the roots were showing under the plastic mulch...poor thing,,, it was starving. Monster size.

This is only my second year with zucchini in an earthbox, so I'm by no means an expert, but I'm confused when you say the soil level dropped four inches, and that you added a quart of fertilizer on the roots at a time. I've never noticed any major soil sinkage with earthboxes. The fertilizer added when an earthbox is set up should be sufficient for the season. Maybe earthtainers are different. My zucchini last year suffered from powdery mildew but it took a while for them to really go down hill, it wasn't an overnight sort of thing.

My containers are DIY subirrigation planters. Earthboxes are larger. It was only in an 18 gallon container...and part of that is for the reservoir. It grew at an enormous rate...so I figured it was going through nutrients to support that massive growth. It could have been just compacting of the soil...but there was no weight other than the actual plant on it.

Thanks for the input to my mystery, DSB22.
