Q.My Ceanothus Has 3 Stems. Can I Cut Two Off?
I have a Ceanothus ‘Lemon Ice’ that I bought with one (trunk) and variegated leaves. Two more trunks have grown next to it with plain green leaves. Can I cut off the two trunks without harming the original plant.

These are not grafted, and do not have a tendency to revert. Likely, the plants growing next to your Ceanothus are not related, and need to be killed as soon as possible.
