I've got two young liquidambars, both planted in last two months, both 70-90 cm high, but from different nurseries. One of them is basically just one erect branch with leaves, and another has a main branch and 5-6 erect branches branching very low.
Is there any imediate need to prune the second one? Generally, should I leave these liquidambars alone (not prune at all during their lifetime), or they need some pruning?
Both nurseries referred them as just "liquidambars", no cultivar is indicated at all. They are fairly rare in my area, and I was happy to find and buy them, even though there was not much info on what the exact species they are actually
