which bark is best?
I need some help figuring out which bark would be best for my plants. I am planning on using the bark in some gritty mix, 5-1-1, and as a soil amendment in some large fabric raised beds.
My choices are the 1/4 minus fir bark pictured on the left or the fine redwood amendment pictured on the right. I didn't have a coin handy, but both seemed uniform and most pieces 1/4 inch and under). I am mainly concerned about the amount of sapwood in the bark. I know that fir bark is highly recommended over redwood on the gardenweb forums, but does this fir bark in the picture have too much sapwood? Would I be better off using the redwood?
Also the description of the redwood fines is interesting:
"Ground up redwood, which is a byproduct of the lumber mills, has been stabilized with nitrogen instead of composted."
Is this nitrogen stabilization a good thing or is it something to steer clear of?
Which bark will make my plants healthier and happier?
Thanks for your help!
