North Texas is a very big area. I'm just northeast of Dallas. Here, this year, there was not alot to harvest. I took what little I had about the 3rd week of June. The bees had already started eating it because of the drought. Really, anytime after it's 75% capped should be ok. Sooner is usually better here because once the flow stops around the first of June, the bees start eating into it to continue brood raising. Unless you are on Mesquite or cotton, we just don't get any flow after late May until golden rod in the fall.
