Hello Garden Experts!
I have recently propagated a plumeria from my mother-in-law's cuttings, however, I am worried that all our hard work will be wasted now that winter is around the corner. The plumeria has grown some flower buds, but none have bloomed just yet. I live in the bay area, and temperatures rarely drop below 40, but I am pretty sure that's still way too cold. I have recently purchased a small greenhouse to put on our balcony, as well as a thermometer & humidity monitor. I am not quite sure what to use to keep the greenhouse warm during the winter.. lamps? heating pads? horticulture bubble wrap? Bringing the plumeria inside is not an option, because our cats will destroy it. Any tips/tricks/suggestions on how to keep our plant alive would be GREATLY appreciated.
