Spring is more suitable for perennials that dislike sozzled conditions or for colder area , allow full establishment before first winter . Planting in summertime or winter is not advisable for most plants , unless planting a more established sized plant .
To set container - produce plants : Prepare planting muddle with appropriate depth and space between . irrigate the flora exhaustively and let the spare piss waste pipe before cautiously removing from the container . Carefully loosen the rootage ball and place the plant in the hole , working grease around the roots as you fill . If the plant is passing origin bound , separate roots with fingers . A few slit made with a sac knife are okay , but should be go along to a minimum . Continue filling in dirt and water supply thoroughly , protecting from direct sun until static .
To plant bare - etymon plant : Plant as soon as potential after purchase . Prepare suitable planting holes , spread out roots and work soil among stem as you fulfil in . Water well and protect from direct sun until stable .
