READ

Think of starting a planter box like you would a flexible recipe that can turn out great no matter which ingredients you choose. Whether you use a pot designed for planting or an old dresser drawer, they’ll both hold soil. Like any recipe, there are a few key steps you shouldn’t skip! You’ll want to make sure there are holes in the bottom of your container so that the soil doesn’t become too wet, which can hurt some plant roots. You’ll also want to figure out a watering system. This can be as simple as watering by hand every few days, or you can take the time to set up a water-efficient irrigation system or olla system that will save you time later on.

Appendix
  •  More information to help inform your choices as you build your planter. 
  • Choosing a Water System
    • Drip Irrigation is made from plastic tubing. It can be finicky to set up but it is highly water efficient and can be attached to automatic timers. 
    • Ollas are unglazed clay pots that can be partially buried in the soil and filled with water. They slowly release water into the ground and reduce the need for frequent watering. There are many do-it-yourself resources for making ollas from standard terra cotta planters or even approximating the effect using old plastic bottles.
  • Organic Nutrients 
    • Organic soil amendments add nutrients that plants need without using chemical fertilizers. They also improve the texture of the soil and its ability to hold water. Here is some more information on a few of our favorites. 
      • Compost is decomposed plant matter that provides essential nutrients and micronutrients for plants.
      • Worm castings are worm poop.  Worm castings are an excellent soil amendment because they help the soil retain moisture and add nutrients.  Worm castings smell less strongly than many other fertilizers!
      • Fish emulsion is a smelly and potent fertilizer.  Fish emulsion is a liquid made from fish remains.
      • Kelp meal is a dry powder fertilizer made from dried seaweed. Kelp meal provides many essential nutrients for plants.
  • Direct Seed or Transplant your favorite plants
    • Choose small, quick-growing, easy to maintain plants for your first planter box.  Try transplanting fresh herbs like parsley, basil, and cilantro. Direct seed radishes, beets, spinach, or mixed salad greens. Marigolds are hardy flowers that will add some color to your planter box.
