If you grow a vegetable garden now you probably know it's that time, even though it's July and hot, it's time for getting your fall garden started.
I have been getting my beds ready for planting and making sure I have the seeds I need for a fall garden.
Here in Oklahoma where I live the average late frost date is the first week in Nov.
But if you do not know yours this an easy way to find out, just go here
You want to look at the fall temp 32 on the left and then follow it to you are in the 50% and that is your average date.
Once you know that, then you figure out when to plant your seeds.
Most of the veggies you'll plant can be planted directly in the garden but you'll need to provide additional irrigation. I use soaker hoses and light mulch. And in some classes, depending on how intense the heat is, I'll use shade cloth a few days before planting to cool the soil some and/or to keep the young plants from burning.
Some veggies like Broccoli, Cabbage, Cauliflower and Brussels Sprouts will need to be started indoors.
Organic Gardening has good information on starting seeds indoors along with Mother Earth New has helpful information too.
Good source for finding a chart or list of when to plant vegetables for a fall garden is through your state extension and this is the one I use provided by Oklahoma State University
And at this site Margaret gives a list of states extension.
I know I have given a lot of links but they have been written so much better than I could explain. I's wonderful how much information is out there. Hope this help
