Lots of things can go in the garden now. Take advantage of some season extension, gentle April rains, and your spring garden eating will be taking place a little sooner. Season extension - row covers, cold frames, and mini greenhouses......
Crops that like it cold.....
Cabbage
Leeks
Onions
Artichokes
Bok Choi
Kale
Spinach
You can use row covers to extend the season and create a little spring heat in this cold year. We use a white, floating row cover (called Reemay sometimes) over hoops made out of 9 gauge wire, which can be found at farm supply stores. You can buy fancier hoops in garden centers, but the home made wire hoops work really well and cost a fraction of the price. You will need bolt cutters to cut the wire.
Happy cold time gardening, and please don't hesitate to get in touch if you have any questions!
