Find straight, unbroken twigs that are two feet or less in length. If you find appropriate twigs that are longer than the others, cut them to size with a sharp knife.
Insert three twigs 4 to 6 inches deep into the soil near the plant you want to support. If you are putting the miniature trellis in a pot, insert them near the edge of the container. Space the twigs 2 to 3 inches apart.
Gather the tops of the twigs together so they form a teepee shape. Secure the tops by wrapping them in twine, 2 inches from the top.
Place the last twig across the middle of the teepee. Lash it to the three other twigs by wrapping it with the twine.
