In the Pacific Northwest, what is the best time to plant seeds for fruits, vegetables and flowers?

Generally after risk of frost has passed for veggies and flowers. I am not 100% certain on fruit (I assume you mean fruit trees?).



If you are starting plants from seeds, start them 4-6 weeks prior to the last frost date and they should be ready and large enough to plant out when frost date has passed.



If you are planting established plants, wait until after frost for veggies and annuals. If you are planting perennials, you can plant before frost date has passed but you want to be sure the plants are hardened off by the nursery. If you are not sure, wait until after frost. (It's generally better to plant perennials in the fall but most people don't and do it in the spring. This is still okay but fall planting is beneficial because the soils are still warm and the plants get a head start for the spring growing season that way-in a nutshell. Having said that, I get plants throughout the year and plant them anyway. Friends give me stuff and I just want to get them in the ground. I live in Zone 9 so my climate is mild and I have that luxury!)



You can also call your local Cooperative Extension Office and they will be able to answer questions regarding planting times. If they have a Master Gardener Program, they are very helpful as well.



Hope this helps! Happy Planting. :)
