We are in the midst of a sizable February snow storm here in the Sierra Nevadas. I peeled back a portion of the onion row cover today to reveal healthy happy and insulated onions!
I love the that the mulch came directly from our black oak trees within 100 yards of these raised beds. The row cover was up-cycled from the past two years when we put grafted fruit tree saplings into the ground and wanted to make them extra safe.
The most important part of this equation lies beneath the soil. This bed (in fact, all of our beds) have been rebuilt this year to be "gopher proof" . We have 1/4 inch galvanized steel gopher wire beneath the ground to 2 feet depth. This together with heavy duty lumber and a variety or wire deterrents above ground will support our crops in thriving.
We also have gold medal gopher deterrents: Miss Nellie and Miss Madge.
