Spring is more desirable for perennials that dislike stiff conditions or for colder areas , allowing full establishment before first wintertime . Planting in summer or winter is not advisable for most plant , unless plant a more established sized plant life .
To implant container - raise plants : groom planting holes with appropriate depth and space between . irrigate the plant life thoroughly and let the supernumerary pee waste pipe before carefully remove from the container . Carefully loosen the root clump and place the plant in the hole , working soil around the roots as you fill up . If the plant is extremely stem attach , separate roots with finger . A few slits made with a pocket knife are fine , but should be kept to a minimum . Continue replete in filth and water exhaustively , protecting from lineal sun until stable .
