Slybacon Posted December 10, 2009 Would the ash from my Webber hot rock BBQ be a suitable fertilizer?? Share this post Link to post Share on other sites
Torsten Posted December 11, 2009 I can't see why not. Mind you, the best use of ash is as a top dressing to discourage slugs and other soft bodied crawlies. Just sprinkle around plants or between rows. Share this post Link to post Share on other sites
Slybacon Posted December 11, 2009 Let the test begin. I covered the topsoil of 1/2 my tomatoes and chillies with the webber ash. Its a very white ash. We'll see if there is a difference. Share this post Link to post Share on other sites
Alice Posted December 12, 2009 Should one be concerned about upsetting the pH due to the alkalinity of the ash? What are those hot rocks made of, charcoal? Or volcanic rock? Share this post Link to post Share on other sites
Slybacon Posted December 13, 2009 Should one be concerned about upsetting the pH due to the alkalinity of the ash? What are those hot rocks made of, charcoal? Or volcanic rock? On the pack it says "burns longer then Charcoal" but i can't figure out what they are made of? it only says "Heat Beads"? Share this post Link to post Share on other sites
reshroomED Posted December 13, 2009 I'd suggest checking particular 'heat-bead' manufacurer's ingredients. Most that I've tried specify not using them to cook until their entire outside is ash, as they release toxic fumes up until then. I'd suspect the residuals in the ash to be less than good for plants,based upon this, but that's only my guess. cheers ed Share this post Link to post Share on other sites
Torsten Posted December 13, 2009 head beads are fine. They contain a bit of coke and lots of sand. Try and sift out any unburnt bits. Share this post Link to post Share on other sites
weedRampage Posted December 31, 2009 (edited) head beads are fine. They contain a bit of coke and lots of sand. Try and sift out any unburnt bits. Coke and coal has high levels of Lead and Mercury in its ash OK for ornamentals but not that good for something you are going to consume given the ever present heavy metal load in the modern diet you could put real wood with some river sand to store the heat for cooking in your webber bbq the ash from wood is a good source of magnesium, calcium, sodium and potassium It has a strong alkalinity but most soils on the coastal area will buffer excess alkalinity. If you used it on an already alkaline soil you might run into trouble. ... a la frazz... the best use for ash is heavy potassium feeders veggies, fruit trees, mull Edited December 31, 2009 by weedRampage Share this post Link to post Share on other sites
reptyle Posted December 31, 2009 Are you talking root vegetables or flowers and seeds? Share this post Link to post Share on other sites
~shameless~ Posted December 31, 2009 Ash from log and wood fires also makes a really good compost accelerant ( nearly as good as burnt lime, like un believeably good ) Share this post Link to post Share on other sites
weedRampage Posted January 1, 2010 Are you talking root vegetables or flowers and seeds? Everything that makes a lot of plant material quickly needs a lot of potassium. Share this post Link to post Share on other sites
