Raised beds and frost
I am assuming that my raised 12" raised beds have higher soils temps than the ground that I planted in last year (same located, new beds). I was wondering if the height of the beds makes them less susceptible to frost as well. Is it likely that the grass near my beds could be covered in frost while the plants in the raised beds are not? My raised beds are also located on a hill that gets a fair amount of wind which might make frosts less likely too.
I guess I am asking if it is reasonable to assume that the micro-climate of my garden might allow me to plant a week or two earlier than the May 15 last frost date. I plan on testing this out, but want to know if any one has any thoughts or experience.
I will post a link to a blog with some pictures.
