- 1). Combine equal parts potting soil, coarse sand and fine-milled peat moss. Add 1/2 cup bone meal to every 12 qts. of the soil mix.
- 2). Fill the new pot 1/3 full with the potting mixture. Use a container one size larger than the pot in which the pencil cactus is currently growing.
- 3). Don a pair of latex or rubber gloves. Place your hand over the top of the cactus pot so the stems of the pencil cactus emerge between your fingers.
- 4). Turn the pot upside down. Thump the pot bottom and sides until the pencil cactus slides out into your waiting hand.
- 5). Set the pencil cactus inside the new pot. Add more soil beneath the root ball, if necessary, so the top of the roots sit 1 inch beneath the rim of the pot.
- 6). Fill in around the roots with additional soil mix. Water the mixture until moisture just begins to drip from the bottom of the pot.
