Erin that is the link for the goat field day. When the page loads just click the text under the picture of the goat and a new page will come up, roll it down a bit and there you are.
As Christina said there are a lot of reasons that the plants are not producing. The most common being too much Nitrogen in the soil. It makes the plant grow very well and be beautiful but they won't set fruit.
Might be time to do some soil testing of your garden plot. Be a good science project for the kids too.
I bought a pretty fancy soil test kit 20 or so years ago for about 100 dollars and got evil looks from the wife when I ordered it, hey we were raising three kids and that would have been a lot of clothes for them. Anyways I tested the soil and did the amendments and the first year yield increased enough that the kit was more then paid for and over the next five years it increased a little every year until leveling off.
Then of course the economy flattened out and we moved so I could get work. LOL
The boss in Enid had a service where the crews went out and sampled fields and made the needed amendments. We built a soil probe and mounted it on the side of a pick-up and it took a three foot sample. The reason being is that the rain will leach out the top couple of feet and the roots will go down to find the deeper nutrients. So often times with an addition of ag. lime to get the PH under control and a very light application of fertilizer their yield went up over a bushel per acre and their fertilizer costs went way down. Boss made money and so did the farmers, win-win.
