Hello PT    I'm ordering a custom soil mix from Southeast Soil in Okahumpka,FL. They will make a custom blend if you order a min of 20+ cubic yards. What is your favorite base soil blend for growing palms in nursery pots. and if you know percentages that would be awesome? Example; 50% Florida peat, 20% Coconut coir, 15% .5" Pine bark, 10% Cypress Fines, 5% Cypress dust.  Thank you  Chris
