Yes absolutely we can ship air plants to you in winter. ! However, you need to take precautions to make sure your air plants arrive healthy and happy. We sell heat packs in our shop. We highly recommend adding them to your order if your outdoor tempurature drops to 40 degrees and below.To avoid your air plants being left out in the cold make sure to ship the package to your daytime address. If you can’t ship to your daytime address make up a plan with your postal worker to leave them with a neighbor our a warm spot. The heat packs help to keep your air plants warm while shipping but will not help if your package is left in a snowdrift.
