Planting in summer or winter is not advisable for most plants , unless planting a more established sized plant .
To institute container - grown plants : Prepare planting pickle with appropriate depth and space between . irrigate the plant thoroughly and let the excess water drain before cautiously slay from the container . Carefully loosen the root ball and place the plant in the mess , work dirt around the antecedent as you fill . If the flora is extremely antecedent bind , separate roots with fingers .
