I’d consider the time of year the supplier deliver them & transplant them then, they must wash the soil of at least shake well as they arrive without any attached, but then you need to wait the 3 years before harvesting…but there’s will be ‘new’. How old are your plants as the lifespan is 20-25 years, if they’re getting on for that I’d start a new bed with new plants, but in the meantime I’d dig up what you can of these ‘old’ ones, transplant, allow them next year to re root themselves and start harvesting 2025 with a view to letting them exhaust themselves the following year or one after….by which time your newly purchased ones will be in full production.
