Working in the garden (whether it's a container garden or an 800 square foot greenhouse) can be one of the joys of nice weather and a free weekend. Not only can you make huge progress in a short time, but it's physical and engaging. The one thing that can get in the way is not having the right tools. For pruning, we fully endorse Felco pruners:

We recommend the but they also have versions for smaller hands and for lefties depending on your needs. For larger jobs check out their lopper.
