Well, I came to the conclusion that next year I will not have enough room in my Studio for all 24 Plumerias.
After reading all 38 pages of the "Harbor Freight Greenhouse projects" thread in the Greenhouse forums and watching over hundreds of you-tube videos. I'm going to need a greenhouse by the end of next year's growing season. I've posted a similar post in that thread but since it is related to my Plumerias, I thought is was only right I share that here. I went and purchased a 10X12 HFGH yesterday and am excited to get it started. That is, once our rainy weather calms down hopefully in late February. I know Ken uses greenhouses to help his Plumerias during their dominant period. Is their anyone else that does the same thing? If so, how has it worked for you?

I commented on your HF Greenhouse Thread. I, too specifically build the greenhouse to house my, at the time 10 plumeria trees as they were getting too tall to fit in the garage. Of course, having the greenhouse, I have increased my plumie population. I knew that was going to happen. hahaha How could it not? I found with protection from frost and a small heater in the GH there are 1-2 that don't go completely dormant. While they aren't in a growing phase, they don't drop all their leaves. Hetty says some varieties do that. I keep my plumies in one area so I can mist them occasionally during their dormant period while other plants in other areas get fully watered. In fact, that is how my gh is arranged, according to sun needs and water.

So after you get your greenhouse built and situated in the right location for max winter sunshine, start researching heating systems. I use a small radiating heat dish. That along with a hanging box fan that runs 24/7 keeps my gh no colder than 55º. Ken showed me a thermostat that I hooked to the heater plug so that it comes on when the temp drops below 55. I don't have to watch it. You'll have fun. But building the gh is just a start.

Thank for the info

Wow! 24 Plumerias Lucky! That would be good forest of Plumerias!!

I know huh tarev and all of them different.
Thinking to myself, what did I get myself into

From the brief experience I had with them. Depending on the variety, some wakes up early, some don't. Some grow faster like a foot a year taller some don't.
If you can keep them in small sized containers, maybe it will hold down their growth a bit, but to be honest they are trees..so it will grow as much as it can.

Hey, you can always sell good seedlings later..a nice side business But pretty sure you would like to see first the blooms of your labor.
