you want to cover flowers from frost which happens at 32 degrees I do it about 40 degrees dont want to chance it...
At -12C , the PVC cracks.
Antarctica is as large as USA and Mexico, combined, so 'coldest month' varies, depending on where you are on the continent. Generally, the coldest month is the month before the sun comes up, and again, this month varies, depending on how far you are on the continent beyond the Antarctic Circle. The coldest temperature recorded on the continent was recorded at Vostok Research Station (Russia) in July 1983. The measurements were −89.2 °C, −128.6 °F; 184.0 K. This is the coldest temperature recorded on Earth.
Before it got demoted, Pluto had the coldest surface temperature at about minus 235. Now the honor goes to Uranus, with an atmosphere reaching as low as 49 K (−224 C).
The coldest time of day is typically right before sunrise, known as the "minimum temperature." This occurs because the Earth's surface cools overnight as it radiates heat back into space without the sun's warmth.
Right before Dawn.

Depending on where you are on the continent, once the sun goes down, the temperature drops consistently. Without any sunrises, usually July and August are the coldest months, just before the sun begins to rise.
A shell. Before that the chicken was covering it.
You may be asking about the forsythia bush. It has small, bright yellow flowers covering the branches even before the leaves have leafed out. When pruning, last year's woody stems are removed near the base of the bush, leaving new growth to produce flowers and leaves.
First off, one needs fresh flowers. Afterwards one must soak the flowers in a solution to preserve it. Once that is done, one must wrap a wire along the full length of the stem in a spiral motion. And finally cut stem at the bottom before covering the bottom in tape.
Any biome will be coldest just before the dawn. The last of the heat absorbed the previous day will have been radiated off into space before the sun rises and starts to reheat the desert again.
