Planting in summer or winter is not advisable for most flora , unless planting a more established sized industrial plant .
To plant container - grown plant : groom plant holes with appropriate deepness and space between . irrigate the plant thoroughly and rent the excess water drainpipe before cautiously removing from the container . Carefully loosen the root ball and place the plant in the hole , working dirt around the root word as you fulfil . If the plant is super root bound , disjoined base with finger’s breadth .

All flora in droughty spot benefit from an occasional recondite watering and a 2 - 3 inch thick layer of mulch . Drought tolerant plants are the backbone of xeriphytic landscaping .
