This is my first winter growing acacia. I built a greenhouse this year to overwinter them in.
I'm looking for advice and tips. Do you think I need to heat the greenhouse?
The species I am growing are relatively frost hardy but still small plants in one gallon containers. There are some larger plants which I'm less concerned about surviving.
I am considering using a seedling heat mat directly under the small plants hooked to a temperature controller.
The idea would be to have the controller kick the heat on around 36F and shut off around 40F just to keep the plants above freezing on the nights when it gets down to 15F outside.
I am also considering a small propane heater for if the power goes out.
I'm not sure if hearing is really necessary thought since they will be protected from the wind and rain.
Also how much and often should I water the acacia during winter? I am concerned that if they get too dry the cold could essentially freeze dry then, I've heard that some water can actually help insulate the soil.
Any advice is much appreciated. Thanks
