Pollen Chart

The overly warm days in my area with their very cool nights can be dangerous for a beekeeper who is eager to inspect the hives, rotate boxes and begin the next season of honey production. March is a deceptive time of year when hives are lost due to starvation as brood production increases and food stores are depleted.

It's tempting to open the hives the check on the amount of food remaining and while in them, to inspect for all the things a beekeeper should to determine the health of the hive. But unless the threat of cold has passed, its wiser to leave the hive intact for now. (The bees have it nicely sealed up with propolis.) The more sensible approach right now is to pull no more than a frame or two looking for stores. If needed, feed fondant and leave the liquid feeding for warmer times.

Snowdrop Pollen

As I was observing the hives yesterday, lots of colorful pollen was being brought in -- mainly olive green and red, which got me thinking about which plants are being visited by the bees.

Box Elder Pollen?

I know that Snowdrops have been blooming a couple weeks in my area, as evidenced by the red photographed on my bees. Trees are just coming into bloom here and so I suspect this lovely olive green pollen in the second photograph may be from a box elder.

I've created this a pollen chart as a guideline, sorted alphabetically by name withing the bloom times. These times are approximate for my area. I hope you'll begin to look at your blooms a little closer now and observe the colorful world of pollen!
