Is there a such thing as a pollen source being too close?

[Charles Wright]

When I start my hives at the beginning of next year should I expect my bees to gather pollen and nectar from flowers within 20-50 feet away or will they be looking for sources further out?

It depends on what they feel is the most economical decision.  They certainly will forage close by, but if there is a huge blooming crop a few miles down the road, they might prefer that over a small bed of something closer to home.  Bees will commonly forage up to 3 miles away from the hive, and I've heard numbers approaching double that in extreme circumstances.

What Member said plus keep in mine that bees mostly visit one type of flower at a time. They do not switch from dandelion to pear to apple to another flower. This means if their are only a few of one type and a lot of another they will for the larger number. When they return and dance, one of the things that they pass on is the quantity. They also select pollen by quality and the proteins that the larvae need. If you have what they need that they cannot get elsewhere then they will use it. If you have the only flowers within normal range, they will use it.

Thanks for the info. I'm in a neighborhood on a half acre lot. Nearly all of our neighbors have lots of flowers, plants and shrubs. We have crepe myrtles, irises, liriope, azaleas, hostas and lots of other stuff I don't know. Our neighbors have similar gardens. I'm just wondering if I should continue to plant more for them or are they going to jump over all of my stuff and hit the neighbors gardens. Thanks again.

Yes.
I planted Phacelia under their noses at entrance, and they ignored it for weeks.
I guess there is no waggle dance for "right here".

Actually there is a dance that says food is close by go find it, it smells like this. This is what causes robbing when you put honey stickies out close to your hives.

@seanconnery, did they eventually gather from your Phacelia?

There is a beekeeper in Canada which he and his family have a large farm, cattle operation, and beehives. Three weeks ago he posted a video of some food plots which he had planted in various locations throughout his farm for the benefit of bees and other insects using various plants, mainly Facelia and Sunflower. He explained this was a great help for late season there. However, I do not think this was as close to his hives as you are asking about. Just food for thought.

@Charles Wright. As the Phacelia grew tall, the returning bees bumped through the flowers and "discovered" the resource.
