"Will it be detrimental to locate my mid-winter burn pile (branches, perennial weeds, etc.) in the middle of the veggie garden? I intend to later spread the ashes (and save the lawn)!"

"We use wood and a bit of coal on our open fire, can I still use the ash even if it contains some small part coal ash?"
Rebecca on Friday 18 November 2011
"Bonnie, that sounds like a good idea to me. You can pile up the branches etc, set fire, then spread the ashes straight away. Be careful that the perennial weeds don't regain a foothold in the soil while waiting in the pile to be burnt, and it would be better not to leave the ash waiting to be spread as any rain would wash the potash down into that small area beneath it. Rebecca, this is a perennial problem. The general opinion nowadays is that because of the levels of sulphur that coal canb contain it shouldn't go on the garden. Back in the time when coal fires were common, the ash and cinders would be used for paths in the garden. My personal feeling is that if it's only a small amount of coal ash in proportion to the wood, then it's probably OK, but I know others wouldn't go near it. "

"I grew my first garden ever last year. Bucket list item, check! It is 73 x 40 and located over the spot I would usually burn my yard debris. I have burned in this approximate spot, give or take twenty feet, since 1983. After tilling the new garden, I tested the soil in a grid pattern over the entire area. I was surprised to find that only the last burn location from a month earlier showed a variance of around 6.5 to 7.5. The pile was about six feet high and twelve feet in diameter and consisted mostly of silver maple and some pine. I made note of this spot as my plan was to grow five, forty foot rows of corn right over it. Results: I could see absolutely no difference in plant health, color or height. The Burpee Early and Often Corn I used all grew to about nine feet. I used Miracle Gro through a drip irrigation system. Most of the corn had two and three tillers and each plant had two to three ears! Unfortunately none was edible! It was the worst tasting corn I have ever tried to eat! What did I do wrong? I called Burpee but they were no help at all. Oops, sorry I went off topic but now back to the subject. My advice as a beginner gardener is; go ahead and burn baby burn! If not for anything else, you can save your lawn. My common sense is telling me that earth worms will be able to move away from the heat but the tiny little bad nematodes nearest the surface will fry which I think is a good thing. Plus you will save a couple dollars on lime expense.I am entered in GrowVeg’s garden contest. You can view my garden plan here - http://www.growveg.com/garden-plan.aspx?p=164352"

"We don't use coal, but do burn wood occasionally and spread it when available (in small doses). I'm just wondering if the ashes from a charcoal barbecue feast (as opposed to 'proper' coal) are ok to use too? "
Kimberley on Friday 18 November 2011
"I live in Fairfax County, Virginia - USA. It is illegal to have open burning of brush piles, etc. No leaf burning either. It has been determined that open burning is quite bad for the environment and I see no reason to add to poor air quality that already causes many health issues.Personally, I am happy to comply and will spend a few dollars on a bag of lime without complaint. For me, organic gardening is a way to decrease my negative impact on the environment - not ADD to the existing burden."
Denise on Saturday 19 November 2011
"Denise, you are certainly entitled to your opinion which is also the opinion of our great law makers. I am talking about the guys in Congress that we all know and love here. I just happen to believe that they are completely wrong. I happen to believe that burning helps the environment. I have billions of years of evolution on my side. What do lawmakers offer us, carbon credits? Fires have naturally (organically) been burning on this planet since time began and I wager that they have played an enormous roll in whom and what we all are. I hope that you can accept my right to voice the opposing opinion."
Larry on Saturday 19 November 2011
"Please forgive me but I have one more point for the opposing side which is; heating limestone to produce lime is a very intensive, energy consuming process. You may wish to Google “carbon footprint for producing lime” As do you, I also care deeply for preserving our environment."

"We use lots of different wood in our log burner, including old fence panels that have been treated with wood stain or painted. Would the ash from this sort of thing be a bad idea to use on the garden?"
Daniel on Monday 21 November 2011
"Just following up on the coal ash matter, you might be interested in the spirited discussion at http://www.allotment.org.uk/garden-diary/1124/using-coal-ash-in-the-garden/. Regarding BBQ charcoal, it's generally felt that if you're using pure charcoal, then it's fine to use the ash. A lot of briquettes have additivies which may not be desirable to add to the garden. The same goes for treated wood. "

"Daniel,personally I would dispose of any ash you get from your log burner containing paint varnish etc anywhere you can (legally) but not on your veg plot.All sorts of chemicals and nasties in these.As for using ash,what about soot from domestic wood and coal fire chimney's ?My Grandad used to dig in soot and coal dust along with manure on his garden in South Wales ( there used to be tons of it lying around when the pits were operating)saying that it was a natural product and it never done his garden any harm.His adage was "God gave us the earth to grow our food and you must replace the goodness that veg takes out the earth"..I grow on clay soil in West Sussex (UK),last year I dug in some soot and it has already improved the soil where I grew potatoes.I know that digging potatoes up helps to break down the soil but compared to two years ago it has improved the texture of the soil.So I will be digging in some more soot on the plot this year.As my friend Gordon,(82 years young!)who has been on our allotment site for 26 years told me "dig it in "boy" (I'm 62 !),it won't do any harm it's a natural by product".."

"Not sure if this discussion is ongoing.But I need to add lime to one part of my property and gypsum to another as well as salt. But I have a high potassium level. Can I then use wood ash from wood burner instead of lime? How much ash? (1 acre). Grateful for any comments.Graham New Zealand"
Graham on Monday 7 May 2012

"I have an occasional bonfire in an old oil drum, and as you say it should be dry, but this seems impossible for me as it is essential to only move the ash when cold, therefore in leaving it for a few days inevatable it rains and all I have is grey sludge which it seems I cant use. There is no way that I can cover the top of the oil drum as obviously a wood cover could catch fire and there is no metal covers large enough to fit over an oil drum. Any ideas please Joyce "
Joyce on Tuesday 7 August 2012
"Joyce, I use an incinerator. When I burn stuff in the evening, I certainly find the incinerator is cold by the next morning. Does your oil drum take several days before it's cool enough to handle? It's no problem if the ashes are still a bit warm when you transfer them to another container until you need them. Or you could put them straight into the compost bin. "

"If you use wood heat indoors, this is a good article, if not please consider burying your waste branches, old logs, brush, leaves etc. covering with straw and soil and plantign a garden over top.

"What about ash from my pellet stove? same as wood ash? Can I use it in the garden or around flowers and bushes?"
Pete on Friday 30 November 2012
"If the pellets are pure wood with no addatives to hold them together the ash would be the same as ash from a wood stove. The type of wood used in making the pellets will affect the quality of the ash. Hardwood ash is better than softwood or coniferous ash. "

"I am happy to have found this discussion! We burn wood in the fireplace throughout the winter. I live in an area known for its heavy clay (alkaline) soil. I mulch heavily with pine needles and amend soil when planting to enhance acidity. I also compost veggie/fruit scraps and garden debris - with great success. I've avoided using the fireplace ashes specifically related to my need for acidity soil (hosts, azaleas, ferns, etc.) So is there a use for these ashes that will work for me? I must admit that I feel guilty about throwing them out."

"Here are 10 things you can do with ash. Or just Google it. http://www.thisoldhouse.com/toh/article/0,,1581470,00.htmlAgain, burning your tree branches is carbon neutral. As things grow, they capture carbon. When you burn them you are simply putting it back. Why is this so incredibly hard to understand? Everything else you here on this subject is about and for, big money carbon credits for giant, greedy, power hungry corporations....Sure, burying your branches would be lovely, that is providing you have big expensive earth moving equipment in order to accomplish the task."
Larry on Monday 7 January 2013
"Hi Larry...I do not use any earth moving equipment and am quite successful at burying excess branches leaves an decaying logs. Yes it is slow, tough work,but there is no schedule to meet. For small scale gardens, with the occasional work bee and help of friends, the results have been remarkable, and I will check out the link provided, but the common held view is that there is too much carbon in the air and it is better left inthe ground. The fact that it can ffed our gardens is a bonus."
tom on Monday 7 January 2013
"Hi Tom, I live on 2 acres and my yard annually produces a large, unsightly debris pile on average 6' by 12' wide. I won't use a chainsaw and sometimes branches are as much as 20 feet long, sticking out all over the place. I would need a large expensive shredder or a backhoe or both to solve my problem. No thank you, I am poor and just one match solves the problem. It's just like a natural lightning strike from mother nature. Again, the CO2 footprint is NEUTRAL! Please understand that trees take CO2 in and we burn the exact same CO2 out. It is a short 50-100 year, neutral cycle. It is a natural, NEUTRAL cycle. On the other hand, man digging massive open quarries then incinerating the rock while releasing massive amounts of CO2 which has been trapped for many millions of years in order to produce lime and other things is the problem. Corporations are NOT neutral, they are negative. We gardeners are NEUTRAL, just like nature. Think outside of the corporate box and you will see. By the way, I absolutely agree with you on the benefits of hugelkulture providing that you are lucky enough to have an energy efficient way to accomplish it. I found a landscaper that delivered a load of chips for free 2 years ago and I had fabulous results this past year. To settle the debate, I would like to concede that your way, if you can accomplish it, is even better because it falls on the plus side of the CO2 meter which reads; (Positive - Neutral - Negative)We cool? I would love to know if I got through on the NEUTRAL position. Neutral is good and I think that corporations have brainwashed everyone into thinking it is not. I don't know but I feel that I am the only one awake and seeing the truth on this. I think, with the exception of man, every living thing on this planet is CO2 neutral. It's a good thing to just be neutral. "
Larry on Monday 7 January 2013
"One last thing... To be perfectly clear, CO2 is not drawn up out of the ground by trees and then released when they are burned. The CO2 in the ground, stays in the ground under your trees. Vegetation extracts CO2 molecules out of the air not the ground as it grows. It simply gets put back out there when plants are burned....a neutral cycle."

Tony Morgans on Friday 1 March 2013
"Hi, Tony. I'd save it to sprinkle it on the soil when the first fruits start to set. Some people add a touch of potash to the potting compost but I've read that it can rush the plants into flower too quickly, so that they don't build up their leaves enough. "
Helen on Friday 1 March 2013
"On the subject of collecting wood ash from bonfires, and keeping it dry, I use an old metal tool box which used to contain a socket set. The two halves are connected by hinges so that it opens like a book. I lay it on the ground and build a small bonfire over it. The ashes and charcoal fall onto it and once the bonfire has died I can close up the box and keep it dry until I’m ready to sieve out the charcoal. I don’t lose ashes onto the ground where they get damp. As an added benefit, if you have your bonfire late in the afternoon, on a winters day, and close the box when it is hot, and still has a high charcoal content, it becomes a heater which I lift carefully into my greenhouse to keep the frost at bay overnight. It takes hours to cool and I still have a box full of cold, dry ashes in the morning."

David Fields on Wednesday 6 March 2013
"Dave, there is no simple formula. You need to know the ph and potassium content of your soil mix, then find out how much ash you can add to take it to the desired levels. Generally wood ash is beneficial if it has no chemicals in it from treated wood, etc., but you can put too much. You will have to get a soil test done from a local company or university etc.You might enjoy my blog called Lively Dirt - the Garden Blog at www.GarthWunsch.com"

"I find your connection with pine needles and raspberries rather surprising. I live in Sweden and am surrounded by forest. 95% coniferous. Around the edges of the trees and under the first 20 yards, grow another forest of wild raspberries. That must have a huge amount of pine needle droppings all the time.and I can only call them an invasive weed. They produce prodigious amounts of very good fruit about half the size of commercial. Perhaps they are used to it. Or a strain that is a little different , but look and taste the same."

"I have three garden plots totaling about 1200 square feet. All organic. We burn 2-3 cords in the wood stove every year, almost exclusively green ash and a little hickory and oak. Throughout the winter the ash gets spread over the snow covered gardens. We move chicken tractors around over that. The combination of manure and ash rots into the garden well by mid spring when we spread compost and plant.Dry summer ashes from bonfires are spread on the asparagus beds and lawn and tossed into the chickens' dust bath boxes. We use the same bonfire pit continuously. It gets sludgy when it rains but a new fire dries it out quite well enough to sift out the charcoal periodically.I've heard that mixing ash with a manure pile while it's composting will release nitrogen undesirably. I normaly dust manure with ash only as I'm spreading it in a garden plot. I'm still considering spreading ash on the dung that our pasture raised pigs leave in the field. I'm supposing that would improve the lightly wooded pasture."
Micheal on Tuesday 25 March 2014
"Personally, I mix my hardwood ash with vegetable scraps I collect in a Rubbermaid trashcan throughout the year (far from house it smells). All the leaf litter, lawn clippings, pulled weeds, and fallen limbs go into a big pile and 2-3 times a year I dump that funky fermented sludge into the pile. Let that sit 2 years turning occasionally and add it to the top of the raised beds and rows of veg garden. It if like black gold and is an environmentally friendly totally organic soil amendment!As far as a post I read earlier about burning natural debris being so bad for the environment.. There are dozens of species of plants that require forest fires for proper seed germination and propagation.. This would indicate to me that it is part of the natural cycle.. just saying"

louise on Friday 8 May 2015
"Dear all and especially Larry - I'm a UK gardener and a keen environmentalist. Here in the UK we have a system of tolerance towards our neighbours (in theory) and have a legislative system to support that. Bonfires are actively discourage by most councils in this country because they can cause quite insufferable nuisance to others, and if that happens, councils can take action. Lets face it, there's little that is more effective at spoiling a nice sunny day (something to be properly relished in this green and pleasant land!) than a smelly bonfire. I therefore advise caution for those who are yet to be turned to the dark side. And yes - most gardeners have many non-recyclable waste piles that appear around the garden. They can't be put through the shredder or disposed of via composting, but I do wish to point out that burning damp or green material in such an uncontrolled manner produces products of incomplete combustion and a host of other by products, (some if this is the black stuff you see when you light your fire). This contaminated air IS air pollution, like it or not, and this release of very fine particulate is now known to cause quite significant impacts on health for all, especially children and vulnerable others. So yes you can argue that we have always had fires, that human beings are meant to scorch the earth - even nature does it in such extremes that we consider our contributions insignificance but is that really the point ?. Do we want to add to poor air quality or do we want our gardening have a positive influence on the local environment?"

"I think I have looked all through this blog (and it's really interesting) but I don't think it tells me how good potash is for brassicas, turnips and chard/spinach. Advice please? (I have LOADS of ash from my hardwood-burning open fire)"
Sue on Tuesday 30 June 2015
"Hi Sue. Brassicas tend to prefer a soil that is slightly alkaline, so applying wood ash to the ground should help to raise the pH of your soil for these crops if your soil isn't already alkaline. I would also suggest that the same rules apply for turnips as they do for other root crops. Leafy crops such as spinach/chard will benefit less from the potassium content of the ash, as these plants need more nitrogen than potassium to encourage luscious leaf growth."
Ben Vanheems on Thursday 2 July 2015

Sue on Thursday 2 July 2015
"And can I ask about comfrey: does that mainly produce nitrogen?

Mr Luke Jones on Saturday 13 April 2019
"Hi Mr Jones. I'm not sure about sulfur being burnt off or not, so hopefully someone else will be able to answer that part of your question. As for adding wood ash where you have previously supplied nettle and comfrey tea, I think that in small doses, it should be fine to add wood ash, as any tea will have long been used up. I wouldn't use large quantities of both tea and ash at the same time though, but following on from each other after time has passed should do no harm."

"Hi Sandra. Bearing in mind all the precautions mentioned in the article, a little wood around your hostas once they are actively growing in spring should do them no harm and may well encourage them to produce their flowers. Avoid getting the ash on the leaves though."

"I have found this forum to be educational, informative, and humorous. My grandparents, my parents and I put ashes form a wood burning stove in the garden. I think its great when something like gardening catches the interests of even my kids who at times spend to much time on Video games. So to have a bi product of heating your house benefit your ability to provide food is I think pretty cool. As for naysayers on burning wood, the bi products of incomplete combustion have allowed us to smoke meat, smoking produces pellicle a protective layer formed by smoke dehydration that resists bacterial growth. I myself like jerky a lot. Gasification, incompletely combusting wood or coal to produce flammable gasses (CO and H2) that can be used as a fuel. So these horrible bi products are being used to better our lives...yeah that sounds pretty bad to me too. The only time fire burns at 100% combustion it is indicated by a blue flame... anyone? So the argument continues. I have 2 points and then I am off my soap box and my $0.02 will have been well spent. If your gardening and enjoying yourself and not lets say, putting moth balls in the ground then go for it. Maybe we should get riled up about The Agricultural Adjustment Act (AAA) a United States federal law of the New Deal era designed to boost agricultural prices by reducing surpluses. The government bought livestock for slaughter and paid farmers subsidies not to plant on part of their land. Surplus, and I thought people were starving, my bad. We definitely need to drive prices up. That's my gardening point. Global warming... I might be wrong but weren't there a whole bunch of movies about an Ice age like starting in about 2002? Again my memory isn't what it used to be, but I think I remember talk of us going through another Ice Age, or was it a plague, or volcanic eruptions with earth quakes, hmm now its global warming. Funny you look up this occurrence, because it is real. It's basically defined as a change in the atmosphere, (happens everyday I thought). I know when global warming can be best pinpointed... you guessed it after the Ice Age. Ok, ok, let me just leave with this thought. I hope this was entertaining, and we are guaranteed 2 things in life. You will be born, you will die. It's how you live in between: follow the Golden Rule and pay it forward (which is the golden rule???).Also anyone in Boise Idaho that has a rhubarb start I could get, purchase, whatever needs to happen, for next year that would be great!!"

"Many thanks for your thoughts there Treana. We live in interesting times I think, but we can be safe in the knowledge that no matter what you view (on just about anything!), gardening is a wholesome and meaningful activity - and everyone loves fresh, nutritious food!I hope you manage to find some rhubarb. I planted some in the spring and it has established well - looking forward to my first harvest next year. I hope you get to enjoy some too."

"Please please advise folks to NOT take the ashes directly from their fire into the compost heap of bin. It is a serious fire hazrd. Wet them completely to ensure no cinders remain."
Louise on Tuesday 17 November 2020
"Hi Louise. Yes, absolutely. It goes without saying that ashes should be stone-cold before adding to the compost heap. I clean my fireplace out BEFORE lighting it. This way the ashes are completely cold. "

"Hi Everyone. I have an extremely small garden - basically a tiny lawn surrounded by plants in containers. I have so far successfully grown dwarf beans and tomatoes, but have had no success with radishes and limited success with onions. Would the ash of hard charcoal from my Weber kettle or wood ash from my ordinary BBQ be effective in container gardening? Your advice would be highly appreciated."
Michael J. Higgs on Thursday 31 December 2020
"Hi Michael. Ash from wood or lumpwood charcoal is fine to use in the garden. Ash from briquettes or charcoal treated with fire starter is best avoided in the garden. Charcoal ash may be used with onions - it helps to deter root maggots, but in containers that is unlikely to be a problem. My preference would be to add it in thin layers to the compost bin. The potting mixes you use in your container garden are likely to have the right pH for most vegetables, and you'd be better off applying a liquid feed or slow-release fertiliser for most vegetables once the initial nutrition in the potting mix is spent. Make sure your onions and radishes get plenty of direct sunshine, and be sure to have them properly spaced. Water often to help both swell in size."

"My wood ash from last year turned brown. Can I still use it"
Mary Bowers on Friday 30 April 2021
"for my tomatoes..."
Mary Bowers on Friday 30 April 2021
"Yes, assuming the ash is just from burning untreated wood and nothing else, it should be fine to use."
Ben Vanheems on Tuesday 4 May 2021
"I just save fireplace ashes; mostly oak; some hickory, maple, etc.I have three south-facing raised beds against the side of my house. The clay soil of Ga. is acidic, so PH of ashes isn't a problem. I deep-bury wheelbarrow loads of non-composted oak and beech leaves, dried grass clippings, and work in organic material like peat moss, more dried grass clippings, ground pine bark, etc. and use very little fertilizer. Plants don't need as much nitrogen as amateur gardeners use. I've got some new cages for tomato and pepper plants to use this year, as even the pepper plants have gotten 6 feet tall. It's when I added ashes [minerals] that they got so large."
David on Tuesday 4 May 2021
" Six feet tall peppers David? That is genuinely remarkable! Clearly the ashes are having the desired effect!"
