Suckering : KerriaHow - to : Planting ShrubsDig a hole twice the size of the etymon orb and inscrutable enough to found at the same level the shrub was in the container . If soil is misfortunate , dig hole even wide and fill with a potpourri half original soil and half compost or soil amendment .
Carefully transfer shrub from container and gently freestanding roots . Position in center of fix , best side facing forward . fulfil in with original soil or an amended mixture if need as describe above . For big shrubs , build a water well . Finish by mulching and watering well .
If the plant life is ball - and - burlapped , remove fasteners and fold back the top of raw gunny , tucking it down into hole , after you ’ve position bush . ensure that all burlap is buried so that it wo n’t wick water away from rootball during hot , dry periods . If synthetic burlap , hit if potential . If not potential , cut away or make dent to allow for roots to develop into the unexampled soil . For larger shrubs , build up a water system well . Finish by mulch and watering well .
If shrub is bare - root , reckon for a discoloration somewhere near the base ; this mark is likely where the soil seam was . If soil is too sandy or too clayey , add organic subject .
