I have some kumquats in 8 inch pots and want to switch them to a different type of pot (from terra cotta to plastic). If I am using the 511 mix and have them in an 8 inch pot now, can I put them in a larger pot like this one from Lowe’s? It is 19 inches wide and 12 inches high. https://www.lowes.com/pd/L-G-Solutions-19-25-in-W-x-12-09-in-H-Oak-Resin-Planter/50445052

I know the better drainig a soil is the less you have to worry about using too large of a container, but I couldn’t find anything in regard to container size using the 511 mix. Is it well drainig enough that you don’t have to worry about potting up to a much larger container?
