Set the container in the ground. Replant
spreading plants inside it to hold in the roots.
If you love lilies and black-eyed Susans, but
hate the way they're taking over your garden and choking
out other plants, here's what you can do:
Many plants multiply by dropping
seeds and by sending out roots that
establish new plants. A layer of mulch
will prevent the seeds from taking
root. But to stop those aggressive roots,
you need a solid barrier. Replant the
spreading plants inside underground
“corrals.” The plastic corrals should
extend at least 10 in. below ground to
prevent the roots from sneaking under
them. This trick won't work with
plants such as strawberries or mint
that spread above ground.
