As evidenced on my Instagram feed, my garden experienced the worst temperature extremes that Texas endured in the new year. We saw the lowest temperature I’ve ever witnessed in all the years I’ve lived in North Texas: -1F.
The historic winter storm knocked out power, water and cell data for 2 days. Our yard was buried in snow for at least 4 days. The community pond was completely frozen over.

The outdoor greenhouse tent could not sustain the plants housed within especially with no power to heat the space. Similarly, my garage was plunged in cold and darkness, freezing the most sensitive plants.

I’m still tallying the losses. The weekend following the storm, we set about to pruning the roses, and removed some dead branches and debris from the front yard. Most of the snow had begun to disappear by this time.

Frost hardiness for some plants seem hit or miss. I had put out some nasturtium seedlings earlier in the year; those were a loss. But I also planted out some romaine lettuce seedlings, and they seemed to have survived.

Needless to say, this means more seed starting and emptying pots to make way for new plants.
Looking ahead at the forecast, it seems that we will be seeing highs in the 70s and lows in the 50s beginning the second week of March. I’m already thinking about all the gardening tasks I have to do to prep the beds to receive new plants.
Back in October I purchased a Quictent pop-up grow house in preparation of housing my frost-tender plants outdoors, including my first-this-year variegated lemon tree. It took 2 tries to get it right, but in the end I was happy with the results. All I have to say is watch the unpacking video, read the instructions, and watch the video AGAIN so that you don’t encounter problems in setup. I confess that I strayed from the step-by-step order and ended up snapping one of the fiberglass poles, held together by stretchy rope.
I walled off about 32 square feet on the patio with a cinderblock border about 3 blocks high, or roughly 2 feet tall.
I then unpacked and erected the tent, though I found it helpful on the 2nd try, to have an extra pair of hands setting it up. Strong winds can make setup challenging.
Originally, DH suggested a pass through, so we cut 4 pieces of lumber, stained them, and purchased additional planter blocks to create something of sliding system for a removable wall.
I picked up a wifi enabled mini hygrometer made by Inkbird to monitor night time internal temperatures. I soon learned that on frigid nights, the grow house really didn’t offer much insulation. I would have to find a way to heat the space.
String lights to the rescue. Or not! I dug through closets hunting down old Christmas string lights. Meanwhile, DH put together a light stand constructed from PVC pipes and erected it inside the grow house.
Unfortunately, the mini string lights didn’t produce enough heat to impact overnight temperatures inside the grow house. But it looked pretty enough!
Blue and white mini string lights, just not enough heat
Temperatures stayed anywhere in the range of 4 to 10 degrees above local outdoor overnight temps. And the tent was brighter too. Overall I used a total of 3 25ft string lights, connected to a splitter on the power cord end. The number of bulbs limited the number of strings that could be connected together, without blowing a fuse–unlike the LED strings that I had hung previously.
On the wall end, the power cord connects to a wifi-enabled dual headed outlet rated for outdoor use. It was handy to schedule times when the lights turned off and on. I could also run automation to turn on the lights when local temperatures dipped below a certain threshold.
All in all, it was a learning experience setting up the tent and heating it. Time will tell if this outdoor grow house setup can endure the harsh winter elements. The only grievance I have is with the delicate C9 bulbs whose filaments break very easily at the slightest blow. I discovered this after I tested every light beforehand, only to find bulbs damaged post installation.
My Brent and Becky’s bulb order has arrived! 450 tulip and narcissus bulbs just in time for north Texas winter planting.
Now digging up places to plant them! In the end we expanded the northern border bed by another foot, weeding out the bermuda and re-installing the stone edge as we went along.
