Here is a truth many natural beekeepers don't want to hear: sometimes bees need help. Not because they're incompetent — they've survived for ages without us — but because we put them in boxes, we take their honey, and we ask them to thrive in environments (cities, suburbs, monoculture farmland) that offer less forage diversity than they would find in the wild.
Feeding is not a failure. It is an acknowledgment of our role as stewards. Done correctly, at the right times and for the right reasons, supplemental feeding can mean the difference between a thriving colony and a spring deadout.
Done incorrectly — at the wrong time, in the wrong amounts, or with the wrong feed — it can trigger robbing, promote disease, or encourage the very behaviors (backfilling, swarming) you're trying to prevent.
Let's learn to do it right.
When: March through early May, or whenever stores are low and natural forage hasn't yet begun.
What: Equal parts white sugar and water by weight (not volume). For example: 5 pounds sugar + 5 pounds (roughly 10 cups) water.
Why this ratio? Because 1:1 syrup mimics the consistency of fresh nectar. It's thin, easy for bees to process, and — critically — it stimulates the queen to lay. The influx of "nectar" signals to the colony that a flow is starting, which triggers brood production.
How much to feed: As much as the bees will take. Offer a gallon, two gallons, five gallons. Refill the feeder as soon as it's empty. Continue until natural forage begins (you'll see pollen coming in on returning foragers) or until the bees stop taking the syrup, which means they no longer need it.
Goal: Prevent starvation during the spring gap and boost population for the upcoming nectar flow.
When: September through October, after the last honey harvest and before temperatures drop consistently below 50°F (10°C).
What: Two parts white sugar to one part water by weight. For example: 10 pounds sugar + 5 pounds (roughly 10 cups) water.
Why this ratio? Because 2:1 syrup is thick — closer to the consistency of honey. The bees don't have to work as hard to evaporate the water, which means they can process and cap it faster. In fall, time is of the essence. You're racing against the first hard freeze.
How much to feed: Whatever it takes to bring stores up to 60-80 pounds (depending on climate). This might mean 10, 15, even 20 gallons of syrup over the course of a month. Offer it in large batches (5 gallons at a time if your feeder allows) and refill until the bees stop taking it.
Goal: Build winter stores quickly before cold weather shuts down feeding entirely.
When: Early spring (March-April) if no pollen is coming in, or late winter (January-February) in warm climates to stimulate brood rearing.
What: Commercial pollen substitute patties (a mixture of pollen, soy flour, brewer's yeast, and sugar) placed directly on top of the frames.
Why? Because brood needs protein, and protein comes from pollen. If there's no natural pollen available (late winter, early spring, or during a dearth), the colony cannot raise brood effectively. Pollen patties fill the gap.
How much to feed: One patty at a time, replaced when it's consumed. Most colonies will take 2-4 patties in spring. Stop feeding once you see foragers returning with full pollen baskets — the natural stuff is always better.
Goal: Support brood rearing when natural pollen sources are unavailable.
When: Mid-winter (January-February) if you suspect stores are running dangerously low but it's too cold to open the hive for a full inspection.
What: Granulated white sugar, either sprinkled directly on top of the frames or placed in a shallow container (like an inverted jar lid) on the inner cover.
Why? Because bees can consume dry sugar in an emergency. They'll add a bit of moisture (from their own saliva or from condensation in the hive), dissolve it, and eat it. It's not ideal — they prefer liquid — but it works.
How much to feed: 5-10 pounds at a time. Check back in two weeks and add more if they've consumed it.
Goal: Keep the colony alive when syrup feeding isn't possible due to temperature.
Knowing when not to feed is as important as knowing when to feed. Feed at the wrong time, and you create problems:
1. During an Active Nectar Flow
If bees are bringing in nectar, they don't need syrup. Worse, if you feed syrup during a flow, the bees may store it in the honey supers alongside real honey. Come harvest time, you'll have adulterated honey — a mix of natural nectar and refined sugar. It may be illegal to sell this as "honey" depending on your jurisdiction, and even if it's legal, it's dishonest.
Rule: Stop feeding as soon as natural forage begins. If you're not sure, check for pollen on returning foragers. Pollen = flow.
2. When Honey Supers Are On
Related to the above: never feed when honey supers are in place. The bees will store your syrup up there, and you'll end up "harvesting" your own sugar water. Remove supers before you begin fall feeding, or wait until after harvest to feed.
3. When Temperatures Are Below 50°F (10°C)
Bees won't take cold syrup. They cluster to stay warm, and breaking the cluster to access a feeder puts them at risk. If it's mid-November and you realize you're short on stores, switch to dry sugar, fondant, or candy boards.
4. When Robbing Pressure Is High
Feeding during a dearth (July, August in many regions) can trigger robbing. The scent of syrup attracts foragers from neighboring hives, who then investigate your hive as a potential food source. If your colony is weak, robbers can overwhelm the entrance and empty the hive in a day.
Mitigation: Feed inside the hive (using a hive-top feeder or frame feeder), never with an entrance feeder. Reduce the entrance so the colony can defend it. Feed in the evening when robbing pressure is lower.
Your choice of feeder affects how and when you can feed:
For most beekeepers, a quality hive-top feeder is the best investment.
"Feed your bees as you would tend a garden: with attention to season, with generosity in scarcity, and with the wisdom to step back when nature provides."
— The Thoughtful Beekeeper, 1911
Spring (March-May): 1:1 syrup + pollen patties until natural forage begins
Summer (June-August): No feeding (unless emergency due to extended dearth)
Fall (September-October): 2:1 syrup to build stores for winter
Winter (November-February): Dry sugar or candy boards (emergency only)
