Chasing the Flow: What Is a Nectar Flow and Why Does It Matter?

If you’ve ever heard a beekeeper say, “The flow is on,” they’re talking about one of the most exciting times in the hive, the nectar flow.

A nectar flow is a period when flowering plants are producing abundant nectar, and honey bees are actively collecting it in large quantities. This typically happens in the spring and early summer, though timing can vary depending on your local climate, rainfall, and the types of plants in bloom. In Virginia, for example, major nectar flows often come from tulip poplar, clover, and black locust.

During a nectar flow, forager bees leave the hive in full force, visiting thousands of flowers each day. They collect nectar, store it in their honey stomach, and bring it back to the hive where it is passed to worker bees. These workers then process the nectar, breaking down sugars and reducing moisture, until it becomes honey, which is stored in wax cells and eventually capped.

So why is this so important?

First, nectar flows are essential for colony growth. The abundance of incoming nectar signals the colony to expand. The queen increases her egg-laying, brood production ramps up, and the hive population grows rapidly. More bees mean more foragers, and more foragers mean even more nectar coming in; it’s a powerful cycle of productivity.

Second, nectar flows are what make honey production possible. Without a strong flow, bees focus only on survival, storing just enough for themselves. But during a heavy flow, colonies can produce surplus honey, what beekeepers are able to harvest.

For beekeepers, recognizing a nectar flow is critical. It’s the time to add honey supers, ensure the colony has enough space, and monitor for swarming, which is more likely when the hive becomes crowded and resources are abundant.

In short, the nectar flow is the heartbeat of the beekeeping season. It fuels the colony, supports pollination, and rewards both bees and beekeepers with one of nature’s sweetest gifts... honey.

Bell & Bee Tips

• Stay one step ahead of the flow. Add your honey supers before your bees run out of space, not after. A crowded hive during a nectar flow can quickly lead to swarming, which means losing a large portion of your workforce right when you need them most.

  
  

• Watch your blooms, not the calendar.

  Nectar flows don’t follow exact dates, they follow nature. Keep an eye on what’s blooming in your area to better predict when your bees will kick into high gear.

• Let the bees tell you. Increased activity at the entrance, bees returning heavy and slow, and fresh white wax being built are all signs the flow is on. When you see it, get ready, because your hive is about to explode with productivity.
