Remove your plant from its container. Gently loosen the roots then wrap them in a layer of sphagnum moss.
In a big bucket, put a few handfuls of potting mix with an equal amount of clay soil. Use your hands to mix it together.
Pack the mixture around the moss covered roots, packing it tight as you shape it into a ball. Stay as close to the plant as you can.
Press sphagnum moss all over the ball to cover it. You may need some help here.
Cut a long piece of string at least 3m long. Lay the moss covered ball over the middle of the string then wind the string all over the ball, crisscrossing it so that all the moss is held inside.
Hang it from a tree branch or on a fence. To keep it watered, soak the ball in a bowl of water (or hold a bucket of water up to it), then leave it to drain. You can also mist spray using a squirty bottle.
