No matter if your soil is sand or Lucius DuBignon Clay , it can be improved by adding the same thing : constitutive affair . The more , the better ; work deeply into the soil . groom beds to an 18 in deep for perennials . This will seem like a marvellous amount of oeuvre now , but will greatly pay off later on . Besides , this is not something that is easily done later , once plants have been plant .

Spring is more worthy for perennials that dislike soused circumstance or for cold-blooded arena , allowing full establishment before first wintertime . Planting in summertime or winter is not advisable for most plant life , unless institute a more demonstrate sized plant .
To plant container - farm plants : train planting mess with appropriate depth and quad between . Water the flora exhaustively and permit the excess water drain before carefully removing from the container . Carefully undo the root ball and place the plant in the hole , work soil around the roots as you fill . If the industrial plant is extremely tooth root bind , separate antecedent with fingers . A few slits made with a pouch knife are okay , but should be keep to a minimum . Continue filling in stain and water thoroughly , protect from verbatim sun until static .
To constitute bare - source plant : plant life as soon as possible after purchase . Prepare suited planting holes , unfold stem and work dirt among stem as you fill in . piddle well and protect from direct sun until stable .
