A big shout-out to reader Gwen for turning me onto these amazing stoneware Sky Planters by Boskke (an “evovled gardening” firm started by two Kiwi brothers, Jake and Patrick Morris), which literally turn everything you thought you knew about tending houseplants upside down. I’m no rocket scientist, but luckily, you don’t need to be one to figure out how the Sky Planters work. The plant and soil are secured by a ceramic ring and plastic mesh. Fill the porous terracotta reservoir at the top of the Sky Planter with H20 and it will slowly nourish the plant in a classic time-release manner.  Now, when you say that your plants are hanging by a thread (or, in this case, a thin stainless-steel cable), you can really mean it, and for once it’s not because you don’t have a green thumb. Sky Plants only need water twice a month!
