Late summer/early fall is an excellent time to plant and divide man perennials. Fall is a time for more active root growth when temperatures are moderate. Fall transplants will be larger than the same plant transplanted in the spring, and these plants will be more established and ready for hot summer weather.
- Plant in time to allow 6 to 8 weeks before the first bard frost.
- Mulch the plants well. This keeps the soil warmer giving extra time for root growth
- Give fall transplants a deep final watering after the first hard frost
- To improve cold hardiness let the entire plant remain in place over the winter
