Is TikTok's Tip For Winterizing Planters Without Bringing Them Inside A Good Idea?
By the time the first frost of the winter arrives, your outdoor plants should already be tucked away somewhere warm and safe. But even empty pots shouldn't be left outside in the cold without some extra precautions. Water from snow and rain can accumulate in upright pots, whether they're empty or full of old soil. As the water freezes and expands, it can cause the pot to crack. TikTok has one tip for winterizing empty planters that can't easily be brought indoors: roll them onto their side! This helps prevent water from pooling and freezing inside leaving broken plant pots around your home and garden. While it may not work in every scenario, overall, it's a great idea!
Terracotta planters are especially vulnerable in freezing weather because the clay absorbs moisture and can expand and contract as the temperature changes, resulting in cracks. Meanwhile, ceramic pots are non-porous in theory, but many are under-fired and so may still absorb some moisture. The safest way to prevent planters from freezing and cracking is to bring all of them indoors for the winter — or at least to a warm and dry garage. However, sometimes a pot may be too big and heavy to easily move, or you may not have enough room to bring it inside. That's where TikTok's tip comes in handy.
Why TikTok's tip works, and when it doesn't
TikTok creator Jess the garden coach (@youcandoitgardening) explained that you can prevent pots from cracking in freezing weather by rolling them onto their side. That way, water doesn't pool inside the planter, but simply rolls off the outside. Turning the pots upside down also works. Finally, to keep your yard looking orderly, Jess recommended rolling the pots out of sight.
Keep in mind that this method isn't foolproof when it comes to preventing terracotta pots from cracking, since the clay itself can still absorb water. Instead, it's best to cover clay pots with a waterproof tarp. Alternatively, you can seal your terracotta pots to keep moisture out, but understand that applying a sealant on terracotta planters slows down drainage, which can increase the risk of overwatering and root rot.
For planters with plants still growing in them, turning them over isn't a viable option. Instead, bring them closer to your home where it's warmer and group them together in a sheltered spot. Raise each pot off of the ground so it doesn't freeze onto the soil and surround them with straw, leaves, or bubble wrap to protect the plants from frost and keep the pots warm and dry. Lastly, if your planter is too large to turn or move, there's another trick to prevent dirt-filled planters from cracking: bury an empty plastic jug into the potting soil. This creates a pocket of extra space for the soil to expand into when it freezes, saving the pot itself from cracking.
