I used a gallon milk jug to make a hanging planter. Cut an opening at the top in front of the handle big enough to water from the top. I cut 4 holes (about 2 inch circles) around the jug spaced out. The jug is easily cut with a knife. Put soil in the jug up to the first hole, put a plant with small roots through the hole, continue up, wetting and pressing down soil as you plant. I used begonias. It did not take long til the jug was a ball of blooms. I used a strong cord around the handle to hang on a tree branch. It tilted a little, so when watering from the top, I had to hold up for the water to get inside good. There are probably many other plants that would be pretty. I was going to do a sedum one this summer because of less watering, but did not get to it--maybe next year.
I hope some of you try this. It is a freebie planter!!
Take care,
Arlene
