Onions grown in raised bed

I did an experiment this year and planted onions in my raised bed. They grew well. The instructions said to expect three inch bulbs, but that didn't happen. Instead, I may have gotten one bulb that was almost three inches, but the rest were around two-and-a-half inches. Some were small and under and inch. 

I think the difference in size had to do with water. The water may not have saturated the dirt as it should have. I'll need to be careful in the future when watering the raised bed.

Today, I planted garlic in the raised bed. This is another experiment. They should be ready for harvest in about four months. If they do well, I will plant garlic to winter in the raised bed to see how they grow in the spring.
