  • Just in Time for National Moth Week July 25, 2014
    The third annual National Moth Week is winding down.  This year it started last Saturday July 19 and runs through this coming Sunday, July 27, 2014.  The inaugural celebration was back in 2012 and I highlighted some of my favorite moths at the time in my weekly article. Moths serve as food for reptiles, birds […] We love hearing from you! Please click here t […]

  • The Wildlife Nursery July 22, 2014
      Gardening often provides the closest encounters we ever have with wild creatures.  It is a solace and a distraction in bad times, and a shared joy in good ones.  ~Ursula Buchan     When you establish a wildlife garden, you need to be aware that at some point in the spring, summer or fall you will […] We love hearing from you!

  • The Good in Grapevines July 18, 2014
    I am sometimes dismayed by the rapid growth of my Muscadine grapevines (Vitis rotundifolia).  Then I spot a bird picking through them and I relax and am glad that I procrastinated on cutting back. Heck, this southeastern native vine can be cut back at any time. This past week I watched the cardinals dancing in […] We love hearing from you! Please click here […]

  • A Monarch Waystation in a Mall’s Landscaping July 17, 2014
    At the Healthy Living Market, which occupies the old JC Penny’s space in the Wilton Mall of Saratoga Springs, NY, there is a new Monarch Waystation site. I had the privilege of doing a landscape renovation to the surrounding island beds and sidewalk gardens this spring. We included many native perennials, and cumulatively the site […] We love hearing from yo […]

  • Smooth Sumac July 15, 2014
      Just a couple weeks ago, some of the bushes along my woodland edges were abuzz with pollinator activity. The flowers of Smooth Sumac, Rhus glabra, were the magnet.   Butterflies, including this Red-banded Hairstreak, Calycopis cecrops, were part of the crowd.   Honey Bees, gathering nectar, to help some bee keeper with his honey supply were also attracted.

  • Sweet as honeyvine July 14, 2014
    This “weed” is a host plant Honeyvine milkweed (Cynanchum laeve) is a vigorous, perennial trailing vine that is native to our eastern and central states.  Some people consider it to be a nuisance “weed”, but I call it Monarch caterpillar food. Hardy hearts I like the honeyvine’s heart-shaped leaves and the fact that I never […] We love hearing from you! Plea […]

  • Yellow and Blue make Beauty in the Garden July 11, 2014
    When I see the bright yellow flowers of the Partridge Pea (Chamaecrista* fasciculata) I tend to think of Sulphur butterflies because it is a larval host for several members of the Sulphur butterfly family. The other day I was out enjoying the diversity of insect activity on the Partridge Pea plants back in my pond […] We love hearing from you! Please click h […]

  • Tracking Down a Lonesome Dove July 11, 2014
    Boy, were husband Matt and I baffled when a friend sent us this picture of a bird nest on the ground, with chick and egg. “What is it?” he wanted to know. “Precocious young?” That was our first thought when seeing a feathered youngster next to an egg—that “precocial” youngster already had feathers when it hatched.

Garden Grounds

If this is coffee, please bring me some tea;

but if this is tea, please bring me some coffee.

~Abraham Lincoln

Many gardeners wake to greet each day with a hot cup of coffee. If you are among those numbers, good news! You can enjoy your coffee twice by tucking away the grounds for use in the garden or your indoor plant containers. If you’re not a coffee drinker, a trip to the local coffee shop can yield free grounds that would otherwise be tossed out. A trip with hubby to the coffee shop yesterday for free “garden grounds” resulted in a large bag full.

Dried coffee grounds serve several purposes in the garden. Used as a mulch they:

  • Limit slug and snail damage on prone plants such as hosta and lilies.
  • Deter cats from digging in garden beds.
  • Are a source of slow-release nitrogen which results in larger, healthier growth in vegetables and plants. Tomatoes especially appreciate the extra boost from a mulch of used grounds.

Remember, spread the mulch no deeper than 1″ and refrain from adding more until the first have completely decomposed.

Other uses for the dried grounds:

  • Coffee grounds can also be worked into beds and pots before planting as a nutrient rich soil conditioner. Use one cup per garden bed and one tablespoon per average size pot.
  • Dried grounds can be added to acidify soil around acid-loving trees, shrubs and plants like evergreens, azalea, hydrangea, blueberry, lupine, butterfly weed, etc.
  • Dried grounds mixed with carrot and radish seeds results in higher yields and less damage from pests.
  • Use in vermi-composting.
  • Dilute 1/2 pound of grounds in a 5-gallon pail of water for a gentle and fast-acting liquid fertilizer.
  • The ideal use for grounds is in the compost pile.

It’s important to note that coffee grounds are a “green” (nitrogen-rich) additive to your garden soil and compost. To maintain a healthy soil balance, additions of “brown” (carbon) material such as dried leaves or straw is also necessary. The general rule of thumb for healthy composting/soil building is one part “green” to three parts “brown”. Thus, adding one pound of coffee grounds to the compost pile or soil should be balanced by adding three pounds of dried leaves, straw etc. (See here for more.) As with any soil amendment, moderation and observation yields the best results. Happy gardening!

  • Happiness is a coffee smelling garden… yum…

    Thanks for the reminder about compost additions… I think I’m entirely too ‘green’ in mine…

  • Lisa Gustavson

    The carbon additions to the compost pile are always lacking for us as well. We have plenty of materials when we remember to use them!

  • My grandmother always used to toss out old coffee grinds into the bushes off her back porch and i must say her rhododendrons looked great.

  • Lisa Gustavson

    I’m tempted to try growing rhododendrons again knowing that. I just can’t keep them alive…Maybe one more try! :-) Thank you!
