Dump 20 lbs. each of Portland cement, peat moss and vermiculite into a wheelbarrow. Put on rubber gloves and thoroughly mix together the dry cement, peat moss and vermiculite with a trowel.
Add water, 4 cups at a time, and mix with the trowel until the hypertufa mixture is the consistency of pudding.
Trowel the hypertufa mixture into a wicker laundry basket, creating 2-inch-thick walls and pressing the damp hypertufa into the wicker to make an impression. Create a 1-inch-diameter hole for drainage in the bottom of the basket with your finger.
Dry the hypertufa planter for three days. Cut the wicker basket away from the completed planter with garden pruners.
