Feeding
Feeding is a normal, important part of beekeeping. Bees gather their own nectar and pollen, but there are times when their natural stores fall short and a colony needs help to thrive or simply to survive. This page explains when and why to feed, what to feed, and how to do it without harming your honey crop or triggering robbing.
Feeding practices vary by climate, forage and local regulations. Treat the guidance below as a sensible starting point and adapt it to your region and your own observations.
When and why to feed
There are three broad reasons to feed a colony.
Spring stimulation. A small amount of thin syrup in early spring can encourage the queen to lay and help a colony build up before the main flow. Use this with care: only stimulate colonies that have the population and stores to support faster growth, and stop well before you add honey supers.
Autumn winter stores. This is the most important feed of the year. After the last harvest, colonies often need topping up so they enter winter with enough stores to survive until spring forage returns. The amount depends on hive type, colony size and the length and severity of your winter.
Emergency feeding. A colony can run dangerously low at any time of year, for example after a long spell of poor weather or a failed flow. If you lift the brood box and it feels alarmingly light, or you find empty stores during an inspection, feed promptly. In cold weather, fondant placed directly above the cluster is the safest emergency option.
Always check stores before deciding to feed. A simple "heft test" (lifting the back of the hive to judge its weight) tells you a great deal once you have felt a few hives through the seasons.
What to feed
Sugar syrup
Plain white granulated sugar dissolved in water is the standard feed. The ratio you choose depends on the season.
| Syrup | Sugar : Water (by weight) | When | Why |
|---|---|---|---|
| Light (thin) | 1 : 1 | Spring | Mimics nectar; stimulates brood rearing |
| Heavy (thick) | 2 : 1 | Autumn | Less water for bees to evaporate; stores quickly for winter |
Dissolve the sugar in warm (not boiling) water and let it cool before feeding. Never use brown sugar, icing sugar with additives, or anything containing them, as the indigestible solids can cause dysentery over winter.
Fondant
Fondant is a stiff sugar paste fed in winter, when bees cannot process liquid syrup and excess moisture in the hive is a problem. Place a block directly over the cluster, close to the bees so they can reach it in the cold. Fondant is also a tidy emergency feed at any cool time of year.
Keep a block or two of fondant in reserve. It stores well and lets you respond to a light colony immediately, even in midwinter.
Avoid contaminating your honey
Never feed sugar syrup while honey supers are on the hive. Bees will store the syrup alongside the nectar, and the result is a crop you cannot honestly sell or label as honey.
The rule is simple:
- Finish feeding before you add supers in spring.
- Remove and extract your honey before you begin autumn feeding.
This single discipline keeps your harvest pure and your records clean.
Avoid triggering robbing
Feeding can set off robbing, where stronger colonies raid weaker ones for the easy sugar. Robbing is stressful, spreads disease, and can destroy a colony in a day.
To reduce the risk:
- Feed inside the hive (with a contact or rapid feeder), not in the open.
- Feed late in the day, towards dusk, so excitement settles overnight.
- Avoid spilling syrup around the apiary, and clean up any that escapes.
- Reduce entrances on small or weak colonies during a feed.
- Do not leave open feeders or wet supers exposed near the hives.
Open feeding (leaving syrup in the open for any colony to take) is best avoided. It spreads disease between colonies and strongly encourages robbing. If you must do it, keep it far from the hives and only in settled conditions.
Record what you feed
Every feed is worth recording. Knowing how much syrup or fondant a colony took, and when, helps you judge whether stores are adequate, spot colonies that consistently run short, and plan next year's autumn feeding more accurately.
In Openbeehive, log feeding as part of the relevant visit so it sits alongside everything else you saw that day. Note the feed type (light syrup, heavy syrup, or fondant) and the amount given. Because the app is offline-first, you can record this at the hive even with no signal, and it will sync later.
See Inspections for how to record a visit and capture feeding amounts.
Over a season, your feeding records become a useful picture of each colony's health. A hive that always needs extra feed may have a forage, population or queen problem worth investigating.
