Helping to prevent fire blight.
Seems to be helping with my apple tree's Fire Blight. Since spraying, I haven't seen any more on the leaves/stems. Lost one tree to fire blight prior to using this. Hoping this saves the second. So far so good.

Root Rot update 2-3 months later: She alive the Garden Phos worked!!! As part of my repotting and treatment. I highly recommend this to anyone that has root rot plants or trees!!! ——————————- Old review Arrived super quick! super fast shipper! Just in a couple days Vs a weeks delivery… which is great when I tell you what’s happening… I herd about this product from my avocado group and on YouTube. My newly stuck grafted avocado tress that came from my Friend that passed away started to have yellowing and welting leaves started to have root rot. So I’m hope this product helps … I will update in few weeks whether or not she survives after repotting

Works on root rot!
After a drought and then drenching rains over the summer my loropetalum bushes began losing leaves. After researching I determined they had developed root rot (phytophora). After using this product twice as a soil drench I have started to see new leaves! See pics. Update - I ended up losing one bush. The other one is coming back but now seeing a couple branches with dying leaves. Maybe this treatment isn’t permanent? Started the drench again.

It works (recommended)
I am really happy with this product. My newly planted avocado tree was not doing so well after planting it. I found out later that the sun was burning it so I put a shade around it and this product made it definitely better!!

Tree fungus still there
There is a black fungus on one of our trees. I haven't seen a difference yet.

It works!
Had bad fungus on a dogwood brush. Used 2 other antifungals with no effect. This product saved my bushes. Use it on my roses too
