DIY: How to Divide your Perennials

How to Divide your Perennials

Water your perennials one week and then one day before dividing if possible. Divide and transplant on a cool, cloudy, calm day if at all possible.

Cut straight down around root ball with transplant spade, aiming to include as many roots as you can. Gently loosen root ball but keep it intact leaving as much soil on as possible to lessen transplant shock.

DIY divide perennialsInspect the plant for obvious places to divide remembering that each new plant needs a balance of top growth and roots. Gently spread leaves, start in centre and cut down to sever into sections. Ensure each section has part of crown, roots, soil intact. After plant has been removed and divided select only the best and healthiest portions to transplant. If you cannot transplant divisions immediately then dig them into a shady bed with wet soil over the roots to keep moist.

Dig planting holes and add new garden soil or compost, mixed into existing soil, into the bottom of planting holes. Add bone meal to planting hole. Transplant new divisions to a depth that allows them to sit at their previous level. Fill in hole with more amended soil pressing down gently around roots to firm and remove any air pockets. Create a slight ridge around plant to hold moisture. Water plants twice: let it puddle and soak in and then repeat. Do not let newly transplanted perennials dry out. Do not fertilize until there is new growth.

Mulching of perennial bed to help regulate soil temperature, to regulate soil moisture levels and thus protect the roots of perennials over-winter. We recommend composted pine mulch.
