Tending my garden for someone else

Buds are forming, weeds are sprouting, lime green leaves are appearing; Portland is emerging from winter, and we’re gardening for someone else. I love watching our garden awake from its slumber and this year we will leave as it's waking up and this makes me a bit sad. As I pull weeds and trim back the brown of winter I can’t help be somewhat jealous of our renters as well. They will be enjoying the fruits of labors and this brings a strange, bittersweet feeling. I have to force myself not to plant new plants. Can I take my garden with me?
