Hmmm ... BUT ...
I put two numbered lists into my "screening bark" blog entry. They are visible only as single-spaced lines, not NUMBERED single-spaced lines. No big deal. I used the "Default" list style.
I tried "Upper Alpha" and "Lower Alpha" style but those were not visible in Preview either. It does let me single-space, however!
Now I'm using FireFox 17.0.1.
Maybe that is the problem. Most software with a "0" in the first decimal place is suspect!
I see the following as a reader:
Pine bark chips' largest dimension should be long: 1/8 inch to 3/8". Say 3 mm to 10 mm.
The middle dimension could be anything from 1/16 inch to 1/5 inch. Say 1.5 mm to 5 mm.
The small dimension ideally would be thin - 1/32" or less up to 1/10 inch. Say less than 1 mm up to 2 mm.
In order to have sufficient water retention, you must have some fine bark particles or peat. I add 5% to 20% commercial peat-based seed-starting mix or fine potting mix.
As a rule of thumb:
Discard what will not pass through ½" hardware cloth - those chunks are too big for small pots.
Use most of what is held back by ¼" screen. The bigger bits are fine for large pots, but too big for seed-starting in cells.
Discard some of what passes too easily through ¼" hardware cloth: it's too fine to improve drainage.
Discard most of what WILL pass too easily through ⅛" mesh. That's dusty. If you want fibers that fine, add a little peat or commercial potting mix instead.
