Great for hydrangeas!

Yes plants responded well

I started using this last Spring on my Arborvitae shrubs and trees. It made an amazing improvement in their growth, fullness, color, and overall appearance. It's easy to apply and only needs to be done in early Spring and again in the Fall.

Excellent product used before and highly recommend.

I use this on my hydrangeas twice a year. It doesn’t take very much of this bag will last me many years. My hydrangeas are already coming out this year looking beautiful and colorful so excited.

My hollies And azalea's loved this stuff.
