Those are all very easy to grow. The biggest issue with them is generally keeping an eye out for pests who want to munch or lay eggs on the greens.

As a side note, the peas will add a rather insignificant about of N back to your soil...especially if you grow them to pod development, which is kinda the point. That said, sugar snaps are awesome so who cares.

Give your collards room to spread their leaves...they'll get a bit wide.

My zone is just a scosh cooler than yours but it is a bit late to start some of these plants from seed here.......generally it is recommended that fall veggie seeds be started at the end of July for planting out right about now. The point is to have them achieve a certain state of growth before cold weather and/or frosts hit. And zone 9 is NOT frost free :-)

The roots crops - beets, carrots - and the peas still have plenty of time from seed but I might consider purchasing starts of the brassicas at your local garden center.

Potatoes are best planted in spring. Even though they are considered a cool season veg, they need some heat to develop a good plant and encourage flowering before really hot weather sets in. And early summer heat helps with warm soils to develop the tubers......soils in fall begin to cool down and that will restrict the development of the tubers.

Thanks everyone for the input. I'm going to buy a few of the brassicas from the local garden store but it will probably be way less than I planned on planting depending on their quality and price.

I may still try planting a few from seed even though it may be to late.

Potatoes will be going in the ground next spring. I'll have to think of something else for that spot, I don't want to leave it bare during the rain.
