If you start gardening "too early" in the spring, your neighbors will definitely be unable to resist making some sort of silly comment about the prematurity of your toil. They'll say things like, "It's kinda early, bub," or "Looks like you got a case of spring fever!" Those neighbors should be handled with polite disdain. If you feel like responding, you should say something like, "Yeah, it's definitely a little early." Then you should put your head back down and say, "Have a nice day." After many years of gardening, I've learned that it's no use to engage these sorts of people in conversations about spring crops. There's no point. They have tomatoes and cucumbers in their minds, and to them, tomatoes and cucumbers are gardening. If you start talking about mustard greens, they will look at you like you just told them that you just dropped a shitload of LSD. It's simply better to entertain their ignorance and play the buffoon who is still wet behind the ears.
I'd say more about this, but I gotta fetch some dinner. Tomorrow I buy mulch.
