Know before you grow

The practical stuff.

Ready to pick when

6 to 8 inches for zucchini (2 to 3 inches across for pattypan), skin glossy and soft enough to mark with a fingernail. Check every single day.

Don't wait: Past 8 inches they turn seedy and watery, and one hidden baseball bat slows the whole plant.

Yield

About 8 lbs per plant over ~5 productive weeks (~8 lb). Fair warning: this is a famous over-producer, pick every 2-3 days or it buries you. Re-sow every ~30 days for a steady supply instead of one glut.
