With temperatures suddenly in the 60s after weeks of frost, overnight temperatures in the 30s (and 20s in some Bay Area places - yikes) and daytime highs barely scratching the 50s, green things are starting to come up everywhere.
Except that all of these green things aren't things that we planted on purpose. In fact, most of them are weeds.
But what's a weed?
Rather than get all philosophical, let's just say that when it comes to growing vegetables, it's pretty easy to tell what's a weed and what's a food because there's none of that grey area that sometimes gets reserved for "pretty weeds" when you're planting things other than food crops.
The new green sprouts in your garden are either vegetables, flowers that you planted on purpose or weeds.
The weeds must go, and if you have flowers crowding out other plants, those can be cleared out as well.
Take a look through the photo slideshow and see whether you can identify the weeds.
Then do a little yard reconnaissance this early spring and get out to the vegetable garden and your yard and pull out the green sprouts that are not food or purposefully planted flowers so that your "pretty weeds" don't turn into huge nutrient-sucking pest habitats.
