Northern California can be a hard place to grow plants
Learning the different environments can be a big help
Every type of plant thrives in a different environment. While one region may be ideal for some plants, it will spell certain death for others. So before you plant this fall, you need to know what can be planted in your region.
The USDA has what is known as a hardiness zone map. It divides up the United States into regions based on the average minimum temperature that can be expected in that area. This gives you an idea of what kind of plants you should consider this coming fall.
But, be aware that this zoning map is not quite the perfect tool for determining what to plant. While it is an excellent tool for narrowing the lists of plants you could grow, it can’t guarantee that all of the plants that are supposed to grow in a region will grow in your area. This is because the Hardiness Zone Map only considers the average minimum temperature for a region and ignores other factors of survivability. It doesn’t consider things like: the moisture level in the air, the absolute minimum temperature, the average temperature, and so on. To know if a plant will actually grow well in your garden, you will need to research that particular plant.
The zone map will help you eliminate some options, but should not be used to confirm the compatibility of a plant with your region.
The Sacramento area is all zone 9 (It is sometimes further broken down into zones 9b and 9a). If you want to view the map and see all the different zones across the U.S.
