I need a growing guide for growing herbs in Oregon Zone 9A

Welcome @Suzanna49

You can get a lot of information from the Garden.org Plants Database via the link at the top of every page. There are filters that include zone and many other characteristics.

Are there any specific herbs that you are looking to grow?

You might also post something specific in the Herb forum. I am in Zone 8 of the Pacific NW, and have a fairly large herb garden. I find most herbs to be easy to care for, usually robust, and often self-seeding. Some self-seed to the point I need to cut them back before they go to seed (vervain comes to mind...)

One thing I would advise against are the cute little herb collection gardens, often featuring sage, oregano, rosemary, parsley, and chives. All of those need much more room than a 3x3 inch plot inside a container. Perhaps if kept tightly trimmed, they work?

Are you growing herbs for culinary use, medicinal use, or a combination? Most are multi-taskers in that regard. Good luck, and enjoy your herb growing.

I am formerly from a banana belt area of California. I have always been able to grow herbs quite easily and prolifically. I definitely want to grow thyme, basil, parsley, rosemary, sage, lemon sage. The climate here on the Oregon coast is very different with less heat, fewer sunny days and lots of WIND.
So any advice would be welcome. 😉

Most of those herbs are pretty easy to grow most anywhere. I'd pick a nice sunny spot out of the wind and plant what you want. For a little extra boost you might put them in a mini-hoop house or use row covers.

Growing most of the culinary herbs without sun may present a problem. I live in Texas and have to put some of mine in part shade because of intense heat, but I have great luck with rosemary, sage, and oregano. I grow chives, mints, chervil, parsley, and cilantro in full sun in winter and part shade in summer or until they croak in the heat which cilantro and chervil do. Just give them a bed with lots of light colored rocks to attract the sun and heat and they should do well enough.

Hello Suzanna49 - A great resource for you are the Lane County Master Gardeners.
