How much to feed, by situation

Use these amounts as a starting point. Your bees, your weather and your local nectar flow matter more than any fixed rule.

SituationRatioHow much to feed
New package or nuc drawing comb1:1Keep the feeder full while they are building comb. A small colony may take about 1 quart every two to three days.
Spring buildup1:1Feed 1 to 2 quarts per week while forage is scarce. Stop once the nectar flow is strong.
Summer dearth with light stores1:1Feed enough to keep the colony from falling behind. You want them to have some stores ahead of what they are using.
Fall winter prep2:1Feed as much as they will take until the hive reaches its target winter weight.
Emergency or starving colony1:1Feed immediately. Start with a quart, then refill as fast as they take it.
Cold winter weather below about 50°FSolid feedUse fondant, sugar bricks or a candy board. Bees usually will not take liquid syrup well in cold weather.

Bees do not store syrup exactly as you give it to them. They have to cure it down and remove moisture before it becomes usable winter food. That is why 2:1 syrup is better in fall. It has less water in it, so the bees do not have to work as hard to turn it into stored food.

Choosing between 1:1 and 2:1 syrup

The syrup ratio simply means sugar to water.

1:1 syrup

1:1 syrup is equal parts sugar and water. It is thinner and more like nectar.

Use 1:1 syrup when you want to encourage activity, brood rearing or comb building. It is most useful for new packages, nucs, spring buildup and colonies that need help while natural forage is still weak.

2:1 syrup

2:1 syrup is two parts sugar to one part water. It is thicker and closer to stored food.

Use 2:1 syrup in late summer and fall when the goal is not to stimulate the colony, but to help them pack away stores before winter.

A simple way to think about it:

Use 1:1 when you want bees to build.

Use 2:1 when you want bees to store.

How much food does a colony need for winter?

This depends heavily on your climate.

In cold northern areas, a colony may need 60 to 90 pounds of stores going into winter. In more moderate areas, 40 to 60 pounds may be enough. In mild southern climates, colonies may need far less, sometimes around 20 to 40 pounds.

The real question is not "how many gallons of syrup should I feed?"

The better question is "how much stored food does this hive already have, and how much more does it need before winter?"

That is why hive weight matters so much in fall. If the colony already feels heavy and has good stores, you may not need to feed much. If it feels light, feed 2:1 syrup until it reaches a safer winter weight.

The Overwinter Feed Calculator can help estimate the gap between what your hive has now and what it likely needs for your climate.

How often should you refill the feeder?

Let the bees tell you.

If they empty the feeder in two or three days, they probably want more. Keep refilling it while you still have a reason to feed.

If syrup sits for a week, starts to mold or the bees ignore it, slow down or stop. They may have found a natural nectar flow, the weather may not be right or the colony may simply not need it.

For a hungry package or nuc, you may be refilling every few days. For an established colony in fall, once a week may be enough depending on feeder size and how fast they take it.

When to stop feeding

Stop feeding liquid syrup when:

  • A strong natural nectar flow begins.
  • You are about to add honey supers.
  • The colony has reached its winter target weight.
  • Cold weather settles in and bees stop taking liquid feed.

You should never feed syrup with honey supers on. If you do, the bees may store syrup in the supers and it can end up in your harvest.

It is also possible to overfeed. In spring, too much syrup can backfill the brood nest, leaving the queen with less room to lay. That can make a colony feel crowded and may push it closer to swarming.

Feed with a purpose. Do not keep a feeder on all season just because it feels helpful.
