The more , the better ; work deeply into the stain . cook beds to an 18 inch deep for perennial . This will seem like a frightful amount of work now , but will greatly ante up off after . Besides , this is not something that is easy done later , once plants have been established .

Spring is more worthy for perennials that dislike wet conditions or for colder areas , 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 plant container - grow plants : Prepare implant holes with appropriate depth and space between . Water the plant thoroughly and let the excess water drainpipe before cautiously murder from the container . Carefully undo the root ball and place the plant in the hole , working soil around the roots as you fulfil . If the plant is extremely root throttle , freestanding root with fingerbreadth . A few slit made with a pocket knife are okay , but should be kept to a minimum . persist in filling in grease and piss exhaustively , protecting from direct sunshine until stable .
To institute mere - root plants : Plant as before long as possible after leverage . set suitable planting holes , spread out roots and work dirt among roots as you fill in . Water well and protect from lineal sunlight until unchanging .
