Raise your right hand and repeat after me...
I, (state your name), will remember that there was a time when I didn't know much about plants or gardening.
I will not roll my eyes or sigh or otherwise indicate in any way that a new gardener's question is one that has been asked a thousand times before. I will answer it.
I will not laugh at new gardeners when they attempt to pronounce botanical names, nor will I correct them and tell them my way of pronouncing it, as though my way is the only way, the right way, even if I know that it is. Well, I won't correct them in public but I won't let them continue to make it obvious that they are a new gardener by continually mis-pronouncing Clematis.
I will remember that the collective wisdom of gardening and knowledge of plants is much bigger than my knowledge of gardening, vast though I think it might be, and therefore, it is possible for a new gardener to encounter some new wisdom or knowledge that I know nothing about. I will learn from them at times.
I will never give a new gardener a thuggish plant, no matter how much they beg or promise to keep it under control.
Finally, I will remind new gardeners that gardening is a way of life, a journey, and once in the light, their lives will never be the same.
Thank you. You may lower your hand now, grab a hoe and head out to your garden. Be careful in the heat!
