For the lower elevations of Oregon, as the saying goes--"we are not out of the woods yet", as far as a chance of frost goes. The forecast looks good up to Wednesday, after that it may change. So, if you are itching to plant something in your yard or garden, you can plant--any shrubs or trees (do watch if you buying them from a place that has been protecting them as they might be a little fragile). You can protect them a little and get them use to the outdoors, by putting them outside during the day and then moving them inside, or put them up against the house. If you buy them from a place where they have been outside--your plants will be fine. As far as flowers and vegi's go, your can plant any cool season vegi's such as carrots, peas, onions, cabbage, lettuce, artichoke and the like. Flower wise, you can plant--Petunia's, Pansies (in the shade) and any perennials. Try to to add organic matter everytime you plant--Happy Gardening--

In the higher elevations, it is best to wait until the end of May to plant most of your flowers and vegi's. You can plant shrubs and trees now and also can put peas in the ground.
