Try things out and see what happens.
Where I am, tomatoes, lettuce, potatoes, peas and lots of others do well if I just grow them in the ground.
Never had much luck with like cucumbers, though.
Last year, I planted cucumbers in a planter. And ended up with enough cucumbers to choke a goat.
So you have to find what works in your local area, and which plants like to grow next to other plants, etc.
Precisely! Around here the cucumbers can be like a weed. The reason we serve so many pickes in Texas is because we get so danged many cucumbers that we have to pickle in self-defense!!!
I am going to try and prepare a bed for that celery though. I like celery and have figured I'd have to do without some of these days. Your method of propagating has spurred me into more action.
