You can use any kind of container to give you desired feelings. Planting in a boot gives me the feeling of being a young teenager wandering through the woods coming across all kinds of old stuff.
After planting put your little creation in a birdbath or anything with a little bit of water 1 inch maximum for ideal oxygen flow which is needed for plant growth. Also the water will not rot on you Which will kill the plant.
God’s best on our quest for a little peace and joy
