Growing vegetables, flowers and herbs has taught me so many wonderful lessons, not the least of which is developing habits of presence. It's amazing to watch something as tiny as a seed, become a plant just bursting with abundance that feeds my family. But that bounty that comes from a small seed requires diligence and care. It means you have to know the difference between a weed and a young plant. It means you need to water and give fertilizer even when it's hot outside and you're especially tired (in fact it's even more important then). It means you have to get dirty and sweaty sometimes, and you have to watch out for things that might harm or even kill the fruits of your labor.
It means you have to notice the needs of something outside yourself.
And it helps to pay attention to the needs inside yourself too.
