The SF Chronicle continues its contraction, and now has too few pages remaining for "garden content." You can still read an archive SF Chronicle/sfgate.com columns. See the quick link to an archive of these columns on this website, in the lower right corner of each page (scroll down). I also encourage you to read Golden Gate Gardening and Wildly Successful Plants, both of which answer many a question I've been asked for the column.
If you have a gardening question not answered in my books, blog, or in accessible past columns, you can send me a question through this website--or come to one of my talks--see the Events page.
