Spinach is a bit difficult in the fall here. Especially since it is so hot and dry right now. Go ahead and grow it, but do not be discouraged if you struggle. Plant your carrots now in very good loose soil. A short variety is best. They take a long time to mature and will be ready in the spring for your eating pleasure. Quick short crops are lettuces and radishes if you want to taste your success sooner rather than later!
Whole foods, and some Ace hardware stores have seeds that have been held indoors in air conditioned spaces. A few big box stores have seeds but they are sitting outside in heat and humidity with really effects germination.

Thanks for the advice! So should I plant the carrots now or wait until the spring?

Nope, you can surely plant carrots now, you can also plant them again in the spring!!! Go ahead and try spinach. On this forum Farmer Dilla recommended Bordeaux Spinach which Botanical Interests has seeds for, they are in Whole Foods, some Ace hardware stores too (and perhaps other places).

Good luck!

Thank you so much!!!!!!

I would get the Southern Living Garden Book to begin with.
What kind of soil did you put in your raised bed?
How will you water it?
Is it in full sun?
Will rabbits or deer get to it?

Happy Gardening!

I also planted carrots in a raised bed this year. I actually did it twice. The first seeds I planted in a pot & transplanted in the garden.. They died. Then I just sprinkled the left over seeds in the bed with some crushed leaves & they are starting to grow now. This is my first year with carrots. Right now they are doing OK.

Spinach is good to plant in the cool season. I Planted my spinach in early spring right after the last frost. I started them by seed in the house & then moved them outside. They will also work in the Fall
