Since they are rated for USDA zones 9-10, I'm assuming you have them in pots and can bring them indoors as they wouldn't survive your winters. Keep it in bright indirect light away from drafts and heating units. Let the top couple of inches of soil dry out before watering thoroughly. Apply a balanced fertilizer once per month. In spring, slowly ?harden off? or acclimate your plant to moving back outdoors by putting it outside in a sheltered location for a couple hours at a time, gradually increasing the time period. In fall, do that in reverse, rather than abruptly moving from outside to inside, which will help lessen the shock. I hope this info helps!
