  • National Invasive Species Awareness February 27, 2015
    It is National Invasive Species Awareness Week 2015.  Somehow the memo that came to my neck of the woods didn’t highlight the “AWARENESS” keyword in the promotional name.  As a result, it seems the invasive species around here thought it was an invitation to move in and celebrate…like Mardi Gras.  HARUMMPH!!!! Early in the week […] We love hearing from you! […]

  • Invasives and Nuance February 26, 2015
    Invasives and Nuance I’ve had a long and complicated relationship with Cup Plant (Silphium perfoliatum), and we finally broke up for good this year. The opening photo shows C. perfoliatum’s cousin, Compass Plant (Silphium laciniatum). It’s Invasive Species Awareness Week, so I thought maybe it’s a good time to be open about my experience of […] We love heari […]

  • Where Do Spiders Go in Winter February 25, 2015
    Do spiders hibernate in winter? Do spiders come inside your house in winter? Where do spiders go in winter? These are questions I’m frequently asked by our readers and also from audiences at conferences and workshops as I travel to speak about Ecosystem Gardening around the country. So lets take a look at how spiders […] We love hearing from you! Please clic […]

  • Yellow-bellied Sapsuckers February 24, 2015
    Beautiful patterns, holes in tree bark, looking like a sort of Morse Code, is not the work of Martians leaving us a message, or wood boring insects. These holes are the work of a brightly colored, medium sized woodpecker, the Yellow-bellied Sapsucker, Sphyrapicus varius. The photo, above, is a cluster of holes (called sapwells) that I discovered less […] We […]

  • Monarchs for President’s Day February 22, 2015
    The long President’s Day weekend, 2015 found me camping at a favorite spot in Southern California’s Santa Monica Mountains, Leo Carrillo State Beach. This campground at the far north end of Malibu includes its own private beach, a pristine cove on the Pacific Ocean.  To the east of CA’s Route 1 (known also as the […] We love hearing from you!

  • Bluebirds Staking Claim February 20, 2015
    It’s a brisk day here in Central Florida with record lows hovering around the freezing mark.  The birds are in full flurry, tanking up on the various berries and fruits that are available for winter dining in my native plant garden. I was pleased to see the Eastern Bluebirds (Sialia sialis) are back house hunting […] We love hearing from you! Please click he […]

  • Gardening for the Birds in the Desert February 17, 2015
    What do desert birds need? Same as every living thing on earth needs, food, water and a place to live. So after you put in a bird bath for the drinking water what can you do to attract birds to the garden? Bird feeders are one easy answer, but you often see a number of […] We love hearing from you!

  • In the Garden, the Eagle has Landed February 13, 2015
    As I looked up to the sky, the vultures were flying overhead in full force.  I suspect the remains of some dropped prey may have been in the 3-acre lot across the street.  Vultures in my neighborhood are a routine affair. I live within a mile (as the crow flies) of a wildlife management area […] We love hearing from you! Please click here to see all the beau […]

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!
