Suckering : KerriaHow - to : Planting ShrubsDig a hole twice the size of the root ball and mysterious enough to set at the same level the shrub was in the container . If land is poor , dig hole even wider and fill with a mixture half original soil and half compost or soil amendment .
cautiously transfer shrub from container and gently separate roots . Position in substance of hole , good side face forward . make full in with original dirt or an amended salmagundi if needed as account above . For larger shrubs , build a water well . Finish by mulch and water well .
If the plant is balled - and - burlapped , take out fasteners and fold back the top of natural gunny , tuck it down into hole , after you ’ve positioned bush . check that that all gunny is bury so that it wo n’t wick water away from rootball during hot , wry periods . If synthetic gunny , hit if potential . If not possible , issue away or make slits to countenance for root to originate into the fresh soil . For larger shrubs , ramp up a water well .
