How do I protect cast iron urns from frost?

Cast iron handles freezing temperatures well, but standing water trapped inside can expand and crack the metal or its contents. Ensure drainage holes remain clear and elevate vessels on feet during winter months. For heavy stone or terracotta planters, lining the interior with protective material prevents moisture from penetrating the porous walls and causing frost spalling.

Can these planters stay outside all year?

Most vintage garden vessels are designed specifically for exterior placement and withstand rain, wind and sun exposure. Cast iron, stone and hard-fired terracotta develop stable outdoor surfaces over decades. Delicate painted finishes or softer stone compositions benefit from sheltered positioning during severe winter storms to preserve their historic patination.

What is the best way to clean weathered garden planters?

Gentle washing with warm water and a soft bristle brush removes loose dirt without disturbing historic paint or established lichen. Avoid harsh chemical cleaners and pressure washers that strip away desirable patination. Allowing natural weathering to continue maintains the authentic character expected from nineteenth century garden antiques.
