Find a place to put your plant with a similar amount of sun throughout the day as the old location. Check that the area is well-drained so your plant doesn't get overwatered. Make sure the hole is the same depth as the root ball and is 2–3 inches (5.1–7.6 cm) wider on each side so it has space to grow. You can also transplant divisions into a flower pot if you want to have a houseplant. with compost or fertilizer where you're planting the divisions. Put a 1⁄4–1⁄2 in (0.64–1.27 cm) layer of compost at the bottom of the hole you just dug so your new plant can get nutrients while it starts growing again. If you don't have compost, use a 0-19-0 fertilizer or bone meal to help promote healthy root growth for your plants. Follow the directions carefully on the packaging so you don't harm your plants.  Too much fertilizer can “burn” your plants and damage them. Wear gardening gloves while working with fertilizer so you don't get any skin irritation. Place the division you cut in the middle of the hole you dug out and press it down gently so it stays in place. Backfill the soil back into the hole, tamping it down with your hand or your shovel occasionally so it comes into contact with the plant's roots. Make a small mound of dirt around the main shoots when the hole is filled in so water doesn't pool there. Use your watering can or a sprinkler to water the transplant thoroughly. The water helps promote new growth from the plant and helps compact the soil around it. When the soil 2 inches (5.1 cm) down is moist to the touch, then you can stop watering. Continue watering the plant every other day for the next 2-3 weeks so it stays hydrated and promotes healthy growth.

Summary:
Dig a new hole that's 2–3 in (5.1–7.6 cm) wider than the root ball. Amend the soil Set the division in the hole and fill it in with soil. Water the plants as soon as the hole is filled in.
