I’ve long held the belief that there are no green thumbs or black thumbs and that gardening is a process of learning and discovery with no peak or end goal. You can garden like a maniac your entire life and never know everything there is to be known. In fact I would say that the more I learn the less I realize I know. That sounds intimidating but it’s one aspect of this hobby/lifestyle that is most rewarding and optimistic. And knowing that you can’t possibly know everything there is to know should help to take some of the pressure off.
That said, I can say with absolute certainty that all gardeners have their weaknesses — there is always that one plant, that dirty little secret whose riddle just can’t be cracked. Mine used to be radishes. I know exactly how to grow them and if you had asked me I would have been able to explain exactly what they need without flinching. But when it came down to it I grew a pretty awful radish. I wrote about my radish problem in the You Grow Girl book because I wanted people to know that they should not give up on those embarassing failures and that it is sometimes one thing to understand what a plant needs on an intellectual level and another thing to apply that knowledge to a real plant.
And then low and behold, just last year I managed to grow my first crop of good container-grown radishes! And today, for a second year running, I have harvested my first tasty, crisp, not-at-all-woody container-grown radishes of the season. Woot! I’ve come to think that my radish mistake probably came down to my own insanely stubborn insistance on growing a variety that just couldn’t take the extra heat and drought on the deck. Again this was one of those instances where I KNEW what I should have been growing and had even appropriately advised many aspiring radish growers while stubbornly soldiering on in the wrong direction in my own garden.
