Great tip. I actually do this. These kinds of containers are also good for holding any soil amendments in smaller amounts too. Bone meal, etc... whatever you regularly use when planting... they're handy & easy.
I am a strong believer in the simple fact is that what matters in this life is how we treat others. I think that's what living is all about. Not what I've done in my life but how I've treated others. ~~ Sharon Brown
