I’ve lived in the central valley of California for my entire life and have always had a vegetable garden.

It’s a great zone for so many reasons but then there are things about it that make gardening a little bit tricky… like the extremely hot weather in the summertime.

You have to make sure you stay on top of your watering schedule, plant certain plants in shade, and plant certain varieties in your fall garden since our spring temperatures can quickly reach high temperatures.

Zone 9b Gardening Tips

When it comes to gardening there are so many factors to consider it can often feel like an impossible skill to master.

In zone 9b it’s very common to have hot days early in spring and late in fall.

So that makes it difficult sometimes to grow vegetables that are cool-season crops such as,

Broccoli
Cabbage
Kale
Brussels Sprouts

I find that those vegetables do better in your fall garden because oftentimes in spring it gets warm too quickly.

Unless you get those crops started very early in spring so you can harvest before the weather is too warm.

3.) Overwinter Certain Varieties

A few great crops to do this with include,
