A friend gifted me with a beautiful little nursery stock mugo pine about 10 inches tall and 14 inch canopy. It has a nice trunk but of course way too many branches etc. When I lifted it from the 1/2 gallon pot it was in I found it was severely rootbound. It is mid September here in zone 6 so I think it is past time to repot. According to the Vance wood guidance repotting should probably wait until next August. In the meantime what should I do with it until spring? My inclination is to slip pot it as it is so rootbound it takes very little water. What do you all think?
