When to start (UK)
The window is late summer to early autumn: remove honey supers, assess stores, treat for varroa (as per label), and ensure a strong, healthy cluster before cold sets in.
Target stores & feeding
- Target stores: Many UK beekeepers aim for ~18–20 kg of honey/syrup in the brood area (local forage and hive type vary).
- Feed type: Heavy sugar syrup (or fondant once cold). For Flow users, feeding is on the brood boxes, not the Flow super.
- Timing: Feed promptly after the final harvest to avoid wasp pressure and cold weather.
Varroa management (post-harvest + mid-winter)
The two high-impact treatment windows are immediately after your last harvest and again mid-winter when brood is minimal/broodless. See our detailed guide: When to Treat for Varroa (UK).
Equipment, entrances & ventilation
- Entrance: Reduce and secure against wasps/mice; fit mouseguards as needed.
- Ventilation: Keep the roof weathertight; ensure a dry hive with minimal draughts.
- Insulation: Consider an insulated crownboard/cover board; avoid chilling the cluster.
- Weight checks: Periodically heft to confirm stores; top up with fondant if light.
Notes for Flow Hive users
- Remove the Flow super: After your last harvest, take off the Flow super for winter.
- Queen placement: Keep the queen in Langstroth brood boxes under a queen excluder during the season; the Flow super is for honey only.
- Spring restart: Refit the Flow super when brood boxes are strong and a nectar flow begins.
Winter FAQs
Can I order an overwintered Flow Hive nuc for spring installation?
Yes — we prepare Langstroth nucs suited to Flow Hive systems with UK-mated queens. See our Overwintered Flow Hive nucs or order directly from Buy Langstroth Nucs for Flow Hive (UK).
Do you supply overwintered nucs in Dorset?
Yes — we are Dorset-based and supply overwintered nucs locally and across the UK.
What’s the safest Varroa schedule around winter?
Treat immediately after your last harvest with supers removed, then again mid-winter when colonies are brood-minimal or broodless. See our full guide: When to Treat for Varroa (UK).
Should I leave any Flow frames on over winter?
No — remove the Flow super for winter. Run the colony on brood boxes only and refit the Flow super in spring when the colony is strong and a nectar flow begins.
