Thank you for the repones Guys.
I ended up getting about 700 pounds of cal nitrate

It was free so I really couldn’t turn it down.
I use lots of mulch every spring that’s really high in nitrogen so it does concern me about how potent this Cal nitrate is rumored to be. I have lots of planting’s around so it’s probably going to be a handful type application like I do with the lawn fertilizer I use.
I’ll try to do some more research online about application rates and post if I find out some good information. Calcium is also really good for plants so it shouldn’t hurt if used moderately.
I do know it works wonders for lawns ( that’s what the guys said that gave it to me ) and of course then Bamboo should be similar since it’s in the same family.
Healthy soil is important to me so moderation is the key.
Thanks again.
