Choose the plants/flowers you
Clean your garden/pots/space by removing the weeds. I know, all plants are our friends, but unfortunately they don't get along so well with pansies and carnations.
Pretend your arm doesn't hurt where Mr. Cactus stung and contently watch the garden.
Plant the seeds following the instructions - some need to be deeper, some at distance, etc.
Rest. Enjoy the view. Think about your friends and wish they will come over.
Post on your blog about a very relaxing household activity.
