I need some help getting my mix right-ready to plant

Craig,

I believe as a minimum, you need to "dilute" either Potting Mix brand with between 15% to 20% Perlite. The well respected Pro-Mix BX contains 14% Perlite and 5% Vermiculite, for reference. Straight Potting Mix will simply get too compacted during the course of the growing Season.

If you REALLY want to Tweak the Combo Mix, use a 3:2:1 ratio of Potting Mix, Decorative Groundcover Bark, and Perlite.

This is what you can experience:

Green, from top to bottom....
