According to my weather data from April 2018, we had a low of 19 degrees on April 3 and a high of 84 degrees on April 25. It is no wonder newcomers to the area or those new to gardening get confused as to what to plant and when to plant it.
Many gardening questions will be answered during the annual Central Oregon Chapter of Oregon State University Master Gardeners Spring Gardening Seminar set for April 20 from 8 a.m. to 4:30 p.m. at the Deschutes County Fair & Expo Center in Redmond. This is a fee-based event with preregistration open until April 13.
The Spring Gardening Seminar 90-minute classes are the major educational focus of the Central Oregon Master Gardener Association and the Oregon State University Extension Service. Presenters for the classes are well known in their profession or in their specialized field of interest. Class choices are many and should be made soon. Class sizes are determined by the capacity of the classroom, and classes do fill up fast.
In addition to the classes, local vendors will participate in the Garden Market, which is open and free to the public. Vendors will offer nursery stock from local nurseries, garden art, landscape products, soil thermometers, row covers (Central Oregon frost protection) and worm castings. There will also be OSU Extension information booths and a silent auction.
