  1. I heard that hair contains nitrogen. I eyed the clippings on the floor when I took my grandson to the barbershop. Was thinking about asking for the clippings on the floor.

  2. Hey Luke, love your videos,I do have a question, I live on land now that was used over 13 years ago for growing cotton. I just started out with gardening here last year, wasnt very succesful. Im wondering if I should have soil tested or should it be ok to just start building beds and plant. Im fairly new so any advice would be great!! Thank you?

  3. startbuck around me use to put them I. Aluminum bag but know I get them in a plastic bag which I dont mind.

  4. I did an experiment with two Air-Pot potted Avocado trees of the same age, about five years old. One I added our morning coffee grounds the other one no. That year the one that got the coffee ground blossomed and give us fruit. There other one didn’t. This year I gave the other one coffee grounds and that thing turned in to a mutant and has blossomed like it had something to prove. So at least for avocados I say coffee grounds work great.

  5. I'm going to start collecting this and put it on my wood chips back to Eden Garden. I've had the wood chips down for a year and it's started to break down but I'm getting antsy to plant so I'm going to put coffee grounds on my wood chips

  6. 3 problems I see with using Coffee grounds in your compost or garden…#1 Coffee is anti bacterial and kills the organisms and worms needed for composting… #2 Leftover caffeine can harm or even kill your plants… #3 Coffee grounds are acidic and can make your soil acidic!

  7. Great video. I'm following the no dig method, largely inspired by yourself and Charles Dowding, I'm growing veg on around 300 square feet. This means I have to find a huge amount of compost to mulch the beds with between 2" and 3" per year. My lawn was old and the soil is very heavy clay so was transformed from a mudbath after heavy rain to concrete in the hot dry summers we get here in Southern Germany, so the lawn really needed biomass to improve it's water holding properties and composition. I figured that the best thing to do would be to use coffee grounds from my workplace, here I get about a gallon a day which would otherwise be thrown into landfill. Like you say, in autumn (fall) there is far more carbon so I set the coffee grounds up straight into the compost to counteract the mass of leaves available. After the end of November I put the coffee grounds straight into the lawn up until March and this (along with another couple of free additives, wood ash and bio char) is bringing on the lawn soil well. I read that caffine inhibits growth and that the nitrogen from the coffee grounds would take time to break down and so be available through the lawn growing season in summer if I stopped around March (my wife doesn't like the smell of grounds on the lawn in summer either). After March I then divide the coffee grounds up between direct input into the compost, using them as a general thin layer over the veg to inhibit slugs and snails, and feeding hazel trees, rods from which I use for bean frames in early spring and then eventually return shredded to the compost as a great source of carbon after a season. Theory is that the coffee grounds alone will offer me a good source of nitrogen and compost balance, coffee grounds, green grass cuttings and carbon from the shredded hazel (alongside leaves and our food/garden scraps) this should give me a great lawn and good veg!

  8. Hey Luke! How do i know that i have a imbalance?
    And im a Little confused – your compost Looks like there is looots of Grass clippings (nitrogen) and only Little leafs (carbon). Now you are Addict more nitrogen through the coffee- isnt there now much to high nitrogen?

  9. I asked locally run , very busy breakfast and lunch house when there for breakfast today,.Amazingly, no one else had bothered to ask, so, I need to pick up MWF, Sat and Sunday….Happily they are 5 minutes away, don’t hesitate to ask,

  10. CAFFEINE IS BAD FOR THE GARDEN!!

    To understand why caffeine is bad for your garden, you need to understand why certain plants produce caffeine in the first place. You probably know that both coffee and chocolate contain caffeine, even though they come from entirely different plants. Those plants aren't even related — they evolved the ability to produce caffeine independently, something biologists call "convergent evolution." When two species evolve the same trait completely on their own, it's a sign that the trait probably has a very useful purpose. For caffeine, that purpose is competition: It kills off any plants in the surrounding area.

    While you might think you squeezed every last drop of caffeine out of those grounds in your french press, think again: A study in the Journal of Agricultural and Food Chemistry found that there can be up to 8 milligrams of caffeine per gram of used coffee grounds, depending on how long the grounds steep in the water. That means that after you brew a shot of espresso, the grounds still contain about as much caffeine as a cup of tea.

    That's why adding coffee grounds to your garden is the last thing you want to do. A 2016 study in the journal Urban Forestry & Urban Greening said it all in the title: "Applying spent coffee grounds directly to urban agriculture soils greatly reduces plant growth." That was true even when they composted the coffee grounds with other organic waste — something experts recommend in the first place. Another study inadvertently found that compost spiked with coffee grounds kills earthworms. And remember how adding organic material attracts helpful bacteria? Well, coffee grounds also have antibacterial properties. Bye bye, little buggies.

    In an article for the Guardian where he did his own informal gardening experiment with coffee grounds, botanist James Wong concludes, "I love a quirky piece of hort advice, and some are repeated so often you assume they are true, but often they call them old wives' tales for a reason." Drink your coffee all you want (eat something first, please), but keep those grounds away from your garden.

  11. How about used tea granules raw washed egg shells droed banana peels dried lemon peels will it work. Really enjoyed your video simple and straight

  12. Luke, i have been saving coffee grounds in a large sealed plastic container. My ised coffee grounds are covered in a greenish gray mold. Can i still use the grounds?

    Love your channel, thanks for all the great info!!

  13. Great video as usual, but I'd like to question what you said about tea bags. I dont know about in the USA but here in the UK the bags are at least partly synthetic, which means they dont rot. By all means put tea leaves in the compost, but be careful with the bags, unless you're happy to fish them out when the compost gets used.

  14. Would it be possible for Migardener to do a video about coffee grounds, and what they CAN AND CANT be used for/on ? because I've watched lots of videos, and they are all telling me different things (for e.g. 1 said that they are great for strawberries, and then the next video said don't use them on strawberries etc.) and I'm getting really confused, and I don't want misinformation to kill my plants, and, because I trust this channel, to give me the correct information, I was wondering if a Coffee Grounds video DO's and DONTS could be made ? =)

  15. How about throwing coffee grounds on eggplants in the garden? I’ve found that they protect the leaves from pests like Japanese beetles and ladybug beetles. I’m really satisfied with my crop of eggplants this summer ?

  16. Also, quail manure is EXTREMELY high in nitrogen. I have to clean out my quail and pheasant cage very often, because it’s so high in nitrogen the quail can get respitory infections.

  17. I have a worm bin, and I love it! It gives me very, very rich soil, and they eat all food scraps that people don’t eat. Also, they reproduce very quickly and can be given to chickens.

  18. Called into the local Starbucks & Coffee Bean & Tea Leaf at 9 am and asked if I could get their coffee grounds. Came by at 1 PM and had about 80 lbs of coffee grounds. My 2 compost piles are nice and hot now!

  19. Luke, thanks for the video. However, I'd like to know your source for that "golden" 5:3 nitrogen/carbon ratio. Seriously, I've seen these ratios ALL OVER THE PLACE. Some say 3:1 carbon/nitrogen and I've even seen/read (now these are all from accredited universities and other accredited sources) say 30:1 (no, that's not a typo) carbon/nitrogen.

    I guess at the heart of it is this: if it smells, that's too much nitrogen–add carbon. If it's not composting and it's too dry, wet it more. If it's still not composting, add nitrogen. At the end of the day, there is no real practical way to measure your compost pile's ratio. In a lab, you'd do it by weight so you'd shred up all the carbon (the leaves, papers, grounds, etc) and equally shred/blend up all the nitrogen in a food processor and weigh it but I STILL cannot get a consistent ratio from any source.

    Your thoughts? Thanks in advance.

  20. My compost has too much nitrogen. I use mostly food scraps. I have plenty of oak leaves but they take years to break down! So I put paper scraps in but I don't think that's ideal.
    Any other ideas for carbon??

  21. Actually, human urine is a great booster for a carbon heavy heap. Seems a waste to flush all that nitrogen down the toilet when you can put it to work for you.

  22. Luke, just curious — do you continue to compost throughout the Winter? Or do you use up all of your finished compost in your garden and beds in the Fall before Winter?
