Winter Planter Boxesare beautiful and easier to do than you’d think. This year, instead of leaving a bunch of empty pots on the patio, I converted them ALL to winter planter boxes. What a difference it made. Dull and drab became festive and fab! And it didnt take very long. And when that was done, we used the left overs to fill my window box. Now, Winters not so bad when I look out my window!
