Cover Plants Before A Freeze

When cold weather comes to Houston, your first thought might be what temperature do plants freeze, in other words, how cold is too cold? There is no easy answer to this. Different plants freeze and die at different temperatures. That is why they are given a hardiness rating. Some plants produce special hormones that keep them from freezing, and these plants have a lower hardiness rating (meaning they can survive colder weather) than plants who produce less of this hormone. That being said, there are also different definitions of survival. A plant may lose all its foliage during a freeze, and some can regrow from the stems or even the roots. So, while the leaves cannot survive a certain temperature, other parts of the plant can.

The best thing to do is bring your plants indoors during a freeze. However I know for some, this might be an issue due to the sheer amount of containers they might have or the pots are simply too heavy to move. We have listed ways you can help protect your plants before a freeze hits.

Coverings to use:

  • Bed sheets

  • Drop cloths

  • Old blankets

  • Pillow cases

  • Plastic sheets (use stakes to keep material, especially plastic, from touching foliage)

  • Bubble wrap
