What many people don’t know is your planters need to be winterized once temperatures begin to drop.

Many times, if a planter is light enough, you can bring the planter indoors in a safe environment such as the garage or shed.  Planters can be stored here, free of freeze and thaw cycle that will occur if rain, snow, or ice collect in your planters. In the event that your planters are too large or heavy to be brought indoors, then we suggest the following winterization methods to ensure planter safety.

If a planter must be left outside, we suggest raising it off of the ground.  This can be done by using shims of wood, or even 2x4’s.  It is important to note that you should make sure not to cover the drainage hole in the planter.  Raising it up off of the ground prevents the cast stone planters from potentially getting frozen onto the ground which can cause cracking in the planters. If you would like a more visually stimulating way to raise your planters off of the ground, most companies also sell pot risers.  These are solid decorative cast stone pieces that can be stained in the same finish as your planter and can be left in place year round.

When initially planting  your containers each season, it is also suggested that pebbles or small stones be placed in the bottom of planters.  This allows for drainage and an added benefit of needing less soil.  Once the pebbles are in place in the bottom of the planters, planters can be placed inside of the planter, and then finished off by filling the planter to the very top brim with potting soil. This prevents any water from collecting and expanded the planters, which leads to cracks.

Ceramic planters should be treated different whenever possible.  Ceramic planters are a bit more fragile than cast stone planters.  Leaving them outside during freezing temperatures puts them at a greater breaking risk.  If you absolutely must leave your ceramic planters outside, then we advise following the above mentioned steps.  Putting a bit of extra effort into moving ceramic planters is always advised. Lightweight planters such as fiberglass or polyethylene can be left out in the winter elements, but just like anything left out in the weather, it is suggested that you take as many precautions as possible to bring them off of the ground and lessen the potential for water to collect inside of them.

By following these steps, you will be taking the precautionary measures to help your planters through the winter and bring them into the next season.
