Like other potted plants H2O as needed. Arctostaphylos not cactus! No or too little H2O is death sentence for sure. One suggestion was if collecting do shortly after rains happen. Rains guarantee whole root system is watered/soil dampened and not just area near tree as people might do. If memory serves a Manzanita guru ( Greg Brenden) told me big(thick/heavy)roots of Manzanita hold much of trees strength/resilience and removing same likely guarantees death of collected tree. If big roots possible to be wound around in container should always be kept along with finer roots at their ends

. Otherwise please leave tree to live in native spot.
