Spring is more desirable for perennials that dislike wet condition or for cold country , allowing full establishment before first winter . Planting in summer or winter is not advisable for most plants , unless planting a more established sized plant .
To embed container - spring up plants : Prepare planting gob with appropriate deepness and space between . Water the plant soundly and let the excess body of water drainpipe before carefully hit from the container . Carefully loosen the root ball and place the plant in the hole , working grunge around the roots as you fill . If the plant is extremely root bound , freestanding roots with finger . A few slits made with a pocket tongue are o.k. , but should be kept to a lower limit . Continue filling in soil and water thoroughly , protecting from verbatim sunlight until unchanging .
