These pups are big enough that they could all be separated from the mother plants. Use a clean, very sharp, small knife and cut the pup off at the base. Let the plants heal in plenty of circulating fresh air. Once the wounds are healed, the plants can be watered again. That usually takes just a couple of days. Enjoy your Tillies!
