How to Divide
To separate plant , the entire source system need to be lifted .
If a clunk is overcrowded , terms to some of the roots is inevitable – but you ’re sound to have so much Modern stuff , it ’s nothing to worry about .

turn up a hole big enough for the root ball and create a minuscule mound for cloak the root .

Backfill and lightly tauten the soil in situation .
body of water gently and profoundly to settle .
Keep the grunge softly moist until transplant are established , providing approximatelyone inch of urine per workweek .
To help hold water in the soil for young plants , add together a two- to four - inch layer of summermulchsuch as bark mulch , hay , sawdust , orstraw .
For mature plants , admit the top one to two inches of grime to dry out between piddle applications .
For containers , choose pots and planters that have drain golf hole . I like to cover the base with two inches of loose material such as unkept pottery or pebbles .
Fill pots with a prolific , well - enfeeble potting territory , then transplant , weewee , and mulch as above .
Container plants will also benefit from a midsummer app of a slow - release fertiliser . utilize a provender with a balanced , all - purpose formula such as 10 - 10 - 10 NPK .
