When you are a gardener, people know that you are the go to person when it comes to plants. They may ask for plant sitting favors. Fellow gardeners will share their plants with you. Once in a while, you may be called upon to foster a plant. I had such opportunity for the first time when a friend with a couple of Roma tomato plants sent a text over asking if I would be interested in fostering them. They were used for a photo shoot and now they needed a home.
