How To Protect Flower Pots Over The Winter
We need to protect the pots and their resident perennial plants from the extremes of the winter weather.
- After several hard frosts, move them into an unheated garage or cold frame.
- If this isn't practical or you have a lot of pots to protect, make a straw bale enclosure where the pots can be placed. Cover with a couple of sturdy pieces of row crop cover (frost blanket) fabric.
- Be sure to give the pots a drink every month or so on a warm day so the roots don't dry out excessively.
- In spring, cut the perennials back and move them into the outside position.
When using perennial plants, they can remain in the pot for at least two seasons before re-potting them into a larger one. Or the perennials can be divided and re-planted back into the same pot with fresh soil-less mix.
When designing your container garden, make sure pots have a mix of plants: thrillers, fillers and spillers. Perennial plants that appreciate well-drained soil are a great choice for containers.
