Feeding bees – autumn feeding

If you have removed most of the hive’s honey then you have removed the colony’s winter larder. Can they replenish their stores or should you feed them?

As we leave September behind us and October tempts us to think there is some mild weather ahead, we should give careful thought to whether each colony has sufficient food stored away to see the bees through the winter. Ideally when the bees go into their winter cluster they should be surrounded by comb full of honey or syrup. It is not impossible to feed bees during the cold periods but expecting them to leave the cluster to visit a feeder is not realistic. The bees may completely ignore the fact that you have provided them with a reservoir of food. Indeed, bees often ignore the fact that there are frames of capped honey on the opposite side of the brood box. There is nothing more disheartening to find that the colony has died of starvation and yet there was ample food in the hive for them.

To feed or not to feed?

If you have taken off most of the honey crop from the hive then the answer is that you must feed them. They are unlikely to be able to store enough winter stores collected from Ivy, Himalayan Balsam of other autumn flowing plants. The choice is to use a manufactured liquid feed or a homemade diluted sugar feed.

Liquid feed can be made at home using white granulated sugar (see Wally Shaw’s recipe below) or by buying a commercially prepared syrup. My own preference is a commercial feed but this can be expensive. The two leading products are Ambrosia and Invertbee which comes in 12.5 or 14kg plastic jerry cans. They are easy to lift and carry over short distances but if your colonies are any distance over rough ground then decanting the syrup into smaller containers makes sense.

Q. How much feed should I give each colony? A. It is difficult to advise but my rule of thumb is buy one jerry can for each colony (then you should have some left over for the spring if it’s needed). Wally Shaw says that a colony needs about 2.3kg of stores/feed a week – so 35kg to take them up to Christmas. The more honey you already have on the colony the less you will need to supplement with syrup.

Q. When should I feed my bees? A. Now! If the weather is still warm enough to inspect your hives, you can see how many stores are in the brood and in any supers that you are leaving on the hive overwinter. Heft the hive – that is, lift up the hive from one side of the floor and get used to its weight. If the hive feels like it is glued to the ground then the bees have stored enough for the winter. You will be lucky to find yourself in this position. More likely it will feel quite light. Then you must feed them

Q. How do I feed my bees? A. There is a choice of feeders- an inverted bucket or a feeder with a lid. I prefer the latter – called a rapid feeder- mainly because you can see how much liquid feed the bees are taking down into the hive. Both of these feeders are placed on a crown board over its central hole. You need to put an empty super around the feeder and then the roof. You will need to check how quickly the feed is being used and top it up frequently. 

A word of warning

Two things to remember. 1. Feeding can lead to robbing if you have more than one hive in your apiary. 2. If you are leaving a super of stores above the brood you MUST remove the Queen Excluder. [It’s good practice to remove it in the autumn to give it a good clean before replacing it in the Spring.

Preparing for winter

After you have removed the last honey harvest you will need to turn your attention to the nutritional needs of your bees over the winter.

The winter period starts at the end of August and continues until the end of December. Preparing the colony for winter is most important.There is much to consider. It can’t all be done in a single visit to the apiary.

  • A colony will need to be checked for disease – particularly the presence of varroa. If the varroa mite count is high then the colony needs to be treated.
  • The beekeeper wants each colony to be producing the majority of its winter bees when the varroa count is as low as possible to ensure that mites do not damage these long lived winter bees.
  • Bees die from damp and lack of food.They can usually withstand the cold.The colony needs through ventilation.
  • If you have a hive with a large brood chamber then it is possible to overwinter with just the brood box. With a National box it is better to have a super on the colony full of feed (ideally honey).
  • Preparing the colony for winter will include feeding to ensure there are enough stores. and also removing the queen excluder.
  • Mouse guards are put in place before any frosts to prevent mice and other small mammals hibernating in the colony.
  • Plastic bags or wire screens are needed where there are woodpecker problems.

February 2025

This is a hazardous month for our colonies and without opening up the hive we can’t know for sure what is happening inside. Resist the temptation -but observe from outside.

The amount of daylight is increasing every day even if the ambient temperature continues to take dips. Some workers may be tempted to make foraging flights in addition to ‘cleansing’ and removal of dead bees. If they bring in pollen, this may fool the queen into an early start of egg laying. The worker bees then must look after the nursery and this can lead to the rapid deletion of stores. Look at the varroa board to see if uncapping debris is accumulating.

Heft the hive to see if the colony needs feeding. This is a bit of an art rather than a science. Can you really remember how heavy that hive was when you last hefted it?

If there has been no activity at the front of a hive on a mild day when the sun has warmed up the hive entrance, alarm bells may be ringing. This may be the exception to the rule of leaving well alone. Lift the roof and look for evidence of activity. I leave a piece of perspex over the hole in the crown board to look through. The bees may of course have clustered away from this source of colder air. If you have first inspected the varroa board you will know where the cluster is. Quickly lift the crown board – are the bees where you expect them to be. If all is quiet, have a sniff. Any unpleasant smells may indicate a problem. Perhaps the smell of mould or worse still a smell like acetic acid which catches your throat like vinegar. You need advice!! More than I can give here.

Jobs for the month

In the apiary

DOC gives season tips for new beekeepers and those who need reminders.

DOC’s seasonal tips

New beekeepers should have learnt all they need to know on their beginners’ course. Well – the course is a good start to your life as a beekeeper, but the real learning comes from the doing. And in the doing we all make mistakes. The key is to learn from your mistakes – or better still the mistakes of others! This blog is intended to give you timely advice and reminders throughout the season.

Hopefully you were able to get some experience at the Society’s apiary in the summer or you were able to get some hands on experience with your own bees. The subjects we are including on the blog will give you the information needed to get the most out of your visits to your bees.

You can comment and ask questions on each blog article and we will respond for all to see. In this way we can help each other to learn together.
