Found a beautiful but somewhat neglected Ilex crenata today, and this evening when I attempted to check the soil pH, the pot is so root bound that i can barely insert the probe. The soil is seriously alkaline and it's September 1st. If I'm gentle with the roots (no heavy pruning), is it safe to repot. I'm Zone 6b, close to the Potomac River in northern VA. Sorry for the insanely n00bish question, but my searches have not helped with this set of conditions. TIA
