Research has shown that coffee is good for you – and it’s also good for your garden and houseplants as well.

Information from Washington State University suggests using coffee grounds in gardens and landscapes – not just as part of compost, but also as mulch.  Coffee grounds in your garden mulch provides nutrients and other benefits that help plants grow.

One caveat: WSU adds that you shouldn’t use coffee grounds in areas where you are “growing plants from seeds.”

Pour-over

Since Americans drink 700 million cups of coffee a day, why not share a little with our plants that have the taste for it? Some of your plants can actually be watered with diluted, room-temperature coffee. Plants with low pH levels can benefit from being watered with black, diluted coffee about once a week. The result is a healthier plant with bushier foliage. (Watch your plant more carefully than usual if you start doing this – stop if the leaves become too yellow).

Some of those plants that can be watered with coffee include low pH plants like these:

  • African violets
  • Azaleas
  • Amaryllis
  • Hydrangea
  • Bromeliad
  • Gardenia
  • Hyacinth
  • Impatiens
  • Aloe
  • Gladiolus
  • Phalaenopsis orchid
  • Roses
  • Begonias
  • Ferns

It’s understood that these plants benefit from their soil becoming more acidic. Or maybe they just like to start their day out right: with a jolt of caffeine.
