Can survive! But first, cut a small piece of meat at the base (incision) of the cut pitaya vine with a knife to expose the lignified part in the middle. This will greatly improve the survival rate! Rinse the secreted liquid with water first to reduce the risk of decay. Then apply a layer of rooting powder on the cut lignified part and put it in a cool and dark place for 24 hours to let the cut wound heal. You can mow the grass and sow the seeds early in the morning on the third day. Watering rooting water mixed with rooting powder once every other week. In order to increase the survival rate, let it sprout as soon as possible.
