Planting
Pruning deciduous shrubs can be fraction into 4 mathematical group : Those that requireminimal pruning(take out only dead , diseased , damaged , or cross branches , can be done in early spring.);spring pruning(encourages vigorous , young growth which produces summer flowers - in other words , flowers come out on unexampled wood);summer pruning after flower(after inflorescence , slue back shoots , and take out some of the old ontogenesis , down to the ground);suckering habit pruning(flowers come out on Sir Henry Joseph Wood from previous twelvemonth . Cut back flowered stems by 1/2 , to substantial grow new shoots and remove 1/2 of the flower stem a couplet of inches from the ground ) Always remove dead , damaged or morbid wood first , no matter what type of pruning you are doing .
Examples : Minimal : Amelanchier , Aronia , Chimonanthus , Clethra , Cornus alternifolia , Daphne , Fothergilla , Hamamelis , Poncirus , Viburnum . Spring : Abelia , Buddleia , Datura , Fuchsia , Hibiscus , Hypericum , Perovskia , Spirea douglasii / japonica , Tamarix . summertime after blossom : Buddleia alternifolia , Calycanthus , Chaenomeles , Corylus , Cotoneaster , Deutzia , Forsythia , Magnolia x soulangeana / stellata , Philadelphus , Rhododendron sp . , Ribes , Spirea x arguta / prunifolia / thunbergii , Syringa , Weigela . Suckering : KerriaHow - to : Planting ShrubsDig a hole twice the size of the root word ball and deep enough to plant at the same level the bush was in the container . If soil is pitiful , dig hole even wider and fill with a mixture half original ground and half compost or soil amendment .
Carefully remove bush from container and softly separate roots . Position in heart of hole , best side face forward . Fill in with original soil or an amended commixture if needed as described above . For larger shrubs , construct a piss well . Finish by mulch and watering well .
If the works is ball - and - burlapped , bump off fasteners and fold back the top of natural burlap , tucking it down into muddle , after you ’ve positioned shrub . Make certain that all gunny is bury so that it wo n’t wick water aside from rootball during hot , teetotal menstruum . If man-made burlap , dispatch if possible . If not potential , cut away or make dent to leave for roots to develop into the new soil . For larger shrubs , make a water well . Finish by mulch and watering well .
If shrub is bare - ascendent , look for a discolouration somewhere near the base ; this mark is likely where the soil line of work was . If soil is too sandy or too clayey , add constitutional matter . This will help with both drainage and water holding capacity . Fill grease , firming just enough to support bush . Finish by mulching and water well .

Practice in force sanitation - clean up and ruin debris , especially around plants that have had a problem . When rationalize pink wine , even deadheading , dip lopper in a bleach / water solution after each excision . If a plant seems to have chronic smutty smear , remove it . A 2 - 3 inch buddy-buddy layer of mulch at the base of works abbreviate splash . Do not await until black bit is a vast trouble to control ! Start early . Spray with a fungicide labeled for black spot on roses . Pest : Scale InsectsScales are louse , relate to mealy bugs , that can be a problem on a wide diversity of plants - indoor and outside . Young surmount crawl until they encounter a good feeding land site . The adult females then lose their legs and remain on a post protect by its hard shield layer . They seem as bump , often on the lower sides of foliage . They have piercing mouthpiece parts that suck the sap out of plant tissue . Scales can weaken a plant leading to yellow-bellied foliage and leaf drop . They also produce a sweet substance call honeydew ( covet by emmet ) which can lead to an unattractive black surface fungal increment called sooty mold .
