When can you replant peonies?

Peonies don't like to be transplanted. However if that's what you have to do, dig a hole about 1ft. deep before planting in a half shaded location.Mix the soil with a liberal amount of well-decayed manure or compost.Plant between September and March in mild weather. Set the crowns no more than 1 inch deep or they may not flower. After planting rake bonemeal into the top 4 inches around the plant taking care not to damage the roots. Peonies like moist but well-drained soil.

Reply:An old, old farm woman told me about 40 years ago to replant them on the first day of September. Works for me.
Reply:it's best not to disturb them, once they have found a home they don't like to be disturbed, they cannot be split like other perennials and sulk if you try (the flower size and colour changes, you could even loose them altogether) unless they are in pots then you can put them in a bigger one or in the ground in autumn. if you really need to move them take a huge root ball with them 1+1/2 times bigger than the plant is in summer and pray (also do this in autumn, water well once transplanted) GOOD LUCK
