Unusually cold zone 8 and Christmas tree lights

10 years ago

So far this year the temps in the upper portions of zone 8 have been way way below normal for several weeks. The citrus in he unheated greenhouse have showed more winter leaf dop in three weeks than all of last year. We re now looking at several straight days with single digit temps. I can not remember the last time even a sinle day was single digits. In anticipation of a 6 degree low I have emptied the greenhouse and brought all containers inside. That was no easy task considering the number and weight of plants. No they are all over the house and I get the joy of taking them back outside in a few days (hopefully).

I have one satsuma outside in the ground that will need a little extra help and I think the Christmas lights will work great. I have tested them inside and they get nice and warm. What would be the best placement of the lights on the tree. I also have my usual frost blanket and a five gallon water buckets from the greenhouse.

I also want o use some lights in the greenhouse to try and keep the temps up a bit to reduce the wld. Any suggestions on placement (on plants, or pots, etc).

On the plus side we are going to pick kumquats from our living room this evening. A bit ironic to pick citrus fruit when you have an inch of pure ice outside.

lying on the ground inside the cover is best. Hot air rises and you want to start near or at ground level. You might want to put several jugs of very hot water in there. If the jugs are open the warm water will evaporate in to the air and condense on the outer surface. This condensing will hold the tree at or above freezing. It works great I used this system in a triple glass enclosure and I had frost on the outer layer with liquid on the inner layer down to 8F.

Arkberry how large is your greenhouse? I have a 6x8 greenhouse and I find a fan for air circulation a must , circulates the warm air from the top of greenhouse to ground level . Plants do so much better with air circulation, I guess it kind of mocks conditions in the real world outside of the greenhouse.Unless you have a massive greenhouse a small portable heater is a must for cold nights like you guys have been having. If your greenhouse is small all you will need is a small 1500w heater for the nights.Speaking of cold going to minus 4 in the next coming nights.
