Suggestions for planting a large barrel
My neighbor just gave me this old barrel, and I'd like to use it as a planter next season:
It stands 35" tall, and the inside diameter is 20".
The inside looks as if it is sealed with a tar-like substance, but there are cracks between the vertical boards/(slats?)
I certainly won't fill the whole barrel with soil, but plan to put something in the bottom half or two thirds (like styrofoam peanuts, for example,) covered with landscape cloth, then soil on top.
OR...I could set another container on top of that layer.
How would you plant such a barrel?
And what might you put in it?
I thought some trailing annuals, like sweet potato vines would look nice, but what else might you suggest?
