You are so right Tom when you said it is "loving to do it". I think the plants grow better for someone who is enjoying them, touching them and talking to them. While I was working with the Master Gardeners we trained quite a few people and some can grow anything and some can't seem to grow much at all. They are the ones that look at it more as a challenge/chore than a joy. They want the plant but they want to work on them in perfect weather, in cute gardening ensembles, with no bugs around them and then they want instant bloom. They usually hire someone to do it and just come to the meetings and talk about their wonderful flowers.
I tromp around muddy, dirty, hair falling down, sweaty, mosquito and fire ant bitten. Once I went into the extension office with dried mud almost to my knees and so tired I could barely shuffle. Agent Ed took one look at me and said "want me to clear off the desk so you can lie down and have a nap?" My love of nature is why I want to grow things but there are others who grow things better than I do. Perhaps it is a little channeling?
