Feeding bees in the summertime #757394

Asked June 21, 2021, 9:40 AM EDT

Hello there, My name is Henry Cakebread. I'm a graduate of your soil science program from a number of years ago and the extension will always reside in a soft spot in my heart. I am writing the first of what will likely be many questions about beekeeping. This is my first year keeping bees so I'm about as novice as it gets but I have run Google in to the ground with my research. I have found some conflicting opinions on this topic so I'm hoping for some expert advice. My colony started as a nuc I purchased this April from some person on the internet that drove it down from Washington. It came as the classic five frames and was guaranteed to have a queen. I have been diligently feeding the gals 1:1 sugar water for most of the spring. I did an inspection last weekend and noticed an empty queen cell on the brood frame as well as a heck ton of new larvae. I am pretty excited about this as on the previous inspection I had noticed a very spotty brood pattern and some decreased activity at the opening. I'm hoping the bees decided they really wanted to go for it so replaced the old lady. I am wondering if continuing to feed them is worthwhile/necessary/helpful. I have seen some people saying that feeding in the summer is bad and others saying they will feed a weak hive straight through from spring to fall. What are your thoughts on this? Additionally I was curious if you had any thoughts on essential oils in the sugar water? I have seen that thymol is effective in controlling chalkbrood and so had dropped a couple drops (very weak concentration) of thyme essential oil in to the sugar water to see what happened. It didn't kill them so that was a good thing right? Basically curious what you think about that. That's it for now. Thanks for taking the time in advance.

Hi Henry, 

Congratulations on starting beekeeping

There is no downside to feeding syrup, unless you are making honey (i.e., you don't want the syrup to contaminate the honey). It also can be expensive. Presently, in the PNW, we are in the peak honey flow, so you likely won't have to feed until the blackberry flow is complete (which, given the heat, may be very soon). As a rule of thumb, you don't need to feed in the summer if the colony has two solid frames of honey on the edge of the nest and brood frames have nectar stored in cells in the top corners of the frame. 

On the spotty brood pattern - could you upload an image?

Chalkbrood is best managed by changing the queen. The spores become ubiquitous in comb over time, but most bees have inherited behaviors to ensure the infection never spreads too far. In addition, the disease can be kept at bay by retiring 20% of your brood comb each year. Adding essential oils to syrup to control chalkbrood is considered an antibiotic, and would require a prescription from a vet (which is can be a hassle and an expense)... best to stick to queen and comb replacement.
