I have some hives in my backyard. There are not many flowers around but about 1.2 km away(air distance) there are a lot of flowering acacia trees. Will my bees able to travel this distance to these flowers and how do I get them to know that there are flowers over there.
I know that my bees may have aleady knew about these flowers but how do I make sure.

Noon time temperature is around 110 deg F and it is always sunny.

1 mile = 1.6 km approx.
