Last year we planted yellow zucchini. The first fruits were very good. By the end of the summer, however, regardless of how large the fruit was, the texture was very hard - almost wood like - especially toward the outside or rind of the zucchini. What may have caused this?

Summer squash should be harvested small. The bigger the squash gets, the harder and woodier it will get. Also, harvesting small means that you harvest before the seeds are mature and the plant feels that it has to produce more fruit to make up for it, which means a bigger overall harvest for you.
