I’ve lived in the same small town my entire life and we are a zone 9b growing zone.

And other than having to deal with really hot summers, it is a great place for a vegetable garden.

We have mild winters and a long growing season which allows you to plant multiple times a year and have extended harvests.

It’s also a nice growing zone because there really isn’t anything that can’t be grown here.

You just have to plant certain vegetables strategically that don’t handle the heat.

For more information specific to zone 9b, check out my Zone 9b Vegetable Planting Guide.

So first I’ll go over some of the best vegetables to plant and then go into all the details.

As you can see, the list is long! There are so many options when it comes to what you can grow.

The important thing is just knowing when to plant everything.

So be sure to get my gardening schedule which will show you exactly when to plant each vegetable.

The only thing you will need to know to use the schedule above is your first and last frost dates. So go here to find the dates for your area.

Once you figure out when to plant everything, the next step is mapping out how often to plant each crop.

To get the most out of the growing season you can do succession plantings, meaning that you plant at various times to get a continued harvest.

For example, instead of planting a whole garden bed of carrots, you can plant one row every few weeks to space out the harvesting.

So below I go over each vegetable and approximately how many days it takes from planting to harvest, so that you can best plan your garden.

Crop Life Spans

Short season crops are great because they can be planted multiple times throughout the season since they are ready for harvest in such a short amount of time.

Half season crops take about half the growing season to reach maturity and can usually be planted twice a year. Once in spring and then again in fall.

Long season crops take a long time to mature for harvest and are typically planted in spring and harvested toward the end of the growing season.

Zone 9b is a great zone for long season crops because the plants have plenty of time to reach maturity.

Some growing zones do not have a long enough season for long season crops to fully mature.
