Great looking gardens all.
One person mentioned morning times and cultivation - one thing I learned fairly recently is that mornings are the best time to harvest as well - especially things like lettuces and tomatoes, they are at their crispest/juiciest then.
So far, our little humble front yard garden has (and will only have this year, due to space limitations - though this front yard bed is a bit of a test....):
9 Tomatoes (variety of heirlooms)
2 Jalapeno
2 Poblano
2 Serrano
2 types of Cukes
2 types of beans
Random leeks thrown in to use up space
We also have lettuces and arugula (and herbs) in pots.
Nothing like fresh picked lettuce and spring garlic dressing.
