Planting in summer or winter is not advisable for most plants , unless plant a more show sized flora .
To imbed container - grown plants : fix set holes with appropriate depth and space between . Water the plant thoroughly and let the excess water drain before carefully removing from the container . cautiously loosen the root orb and place the flora in the cakehole , working soil around the roots as you fill . If the plant is extremely antecedent bond , separate origin with finger’s breadth .
