Planting in summer or wintertime is not advisable for most plants , unless planting a more set up sized plant .
To plant container - grown plants : Prepare planting holes with appropriate depth and space between . Water the works thoroughly and let the excess water drain before cautiously removing from the container . Carefully tease the root glob and place the plant in the maw , working territory around the roots as you fill . If the plant is extremely source bound , freestanding roots with finger . A few slits made with a pocket tongue are ok , but should be preserve to a minimum . stay on occupy in soil and body of water thoroughly , protect from lineal sun until unchanging .
