Additional Information

Exclusive | Self-Watering Railing Planter Installs in Seconds

  • Convenient self-watering railing planter is simple to install
  • Straddles two sizes of rails — no brackets needed
  • Just fill the reservoir and plants get the water they need, when they need it
  • We recommend one 20-quart bag of our premium Organic Self-Watering Potting Mix; each of these planters holds 20 quarts

Now it’s easier than ever to have lush, colorful plants along a deck railing. This cleverly designed planter securely straddles rails made from both 4" and 6" milled lumber (actual width 3-1/2" and 5-1/2") — no mounting hardware needed. Best of all, it’s self-watering; simply fill the reservoir and plants receive water as they need it.

Best Uses

  • Flowers
  • Porch railing

The boxes are attractive and were easy to set up and plant. My only objection is that unlike other self-watering planters you sell, this one does not have a water level indicator so I'm left to guess whether it needs more water or not. If it had that I'd give it 5 stars.
