gritty mix question
I finally finished making my 5-1-1 for 4-16" container, 2-22" containers, 3 3' planter boxes and 1-2' planter box. Thanks everyone for all the assistance and patience.
Now I just realized that my 2 cherry trees are coming in 2 weeks and i don't even have a container or soil components for them. I plan to make gritty mix with gran-i-grit, perlite, napa floor dry, and bark. (I have yet to get any of the parts). I think the bark is going to be the toughest part and will likely need to try and screen my 5-1-1 bark to maximize what i can get out of it. Can i screen all the componets over 1/4 inch screen then aluminium insect screen and keep everything in between(i dont want to have to buy more than 1 more screen- i already bought 1/4 inch and 1/2 inch)? i am OK with having a little bit more water retention. Also should i use .5 parts granite and .5 parts perlite?
