How to Divide Intersectional and Tree Peonies

Herbaceous paeony are just one of the three type of paeony out there . Two relative , intersectional and tree peonies , can be divided in fall like their herbaceous cousins . When it comes to Sir Herbert Beerbohm Tree peonies , only multistemmed types are divisible . Multistemmed Sir Herbert Beerbohm Tree peonies post up many shoots , so they can be broken up with a few stem to each division . Single - stem tree paeony have just one woody bole , which ca n’t be sliced in half . To split up a tree diagram or intersectional paeony , get the picture it up , put it under a tarpaulin the night before cutting , and replant it after division , with its eyes 2 to 3 inches below the soil surface . The difference , however , clip up in the actual naval division of the plants . Easy , correct ? Just be aware of the difference between intersectional and tree paeony when it comes to the actual division process .

Look intersectionals in the eyes before making divides

Intersectional , orItoh , peonies ( named for Toichi Itoh , their original disseminator ) can be cut apart at the most narrow connections between larger small-arm of ascendant , each at least 6 inches long .

Cut the intersectional at a thin point between big sections , as you would if you want just a bit of a big peppiness root in the kitchen .

As you visualize the cuts , remember that intersectionals send up fresh root every spring , so they have eye like herbaceous paeony do . Leave at least three eye on each new division to ensure stem and flowers the following year .

A tree peony is a Gordian knot: one smart cut can get the job done

Sir Herbert Beerbohm Tree peonies are woody perennial that bloom on quondam Natalie Wood , so there are no eyes to vex about when separate . They keep stems aboveground year - round , and sport many wiry roots around larger , fatter ones . Only multi - stemmed tree peonies are divisible . They send up many shoot and can be break up with a few stems to each sectionalization . Single - stem Sir Herbert Beerbohm Tree peonies have just one woody trunk , which really ca n’t be sliced in half : you could test , but chances are disease or pests will record the flora through the massive wounding you ’ve created and vote down the peony .

Take your time and look carefully at the fatter root for the simplest snub that will free up new plants . check that you get lots of root and a few stem on each division .

Make cut with a pruner at the right nexus : the spot in the thick root where a slicing will let you pull two plants apart . Sometimes , one respectable cut is enough to divide the peony .

snipping and pry judiciously , so that each division receive at least 6 inches of rich root to sustain top growth . If you feel that a division lacks enough ascendent to prosper , cut back some of the woody top growth to ease the strain .
