veg garden ph
I had seen several posts long time ago about the benefits of using
fireplace ash blended into the vegetable garden as a means of providing many minerals...we burn oak primarily. A recent search shows that most plants like scallion and tomato need slightly acid conditions, but the ash is obviouly basic in nature. I heavily mulch the garden using rotted leaf mulch so there is plenty of organic matter blended in. If upon testing, I need to lower the ph due to the ashes, what is typical for this application ... I know that lime is used to raise ph, but unlike grass lawns, a veggie garden is not supposed to get past 7.0 I was thinking of spreading oak shavings from woodworking as a means to add acid. TIA for any tips Stew Corman |

Oak shavings will reduce the pH of your soil for a while, but as it
decomposes they will tend toward neutral pH. In the process they will tie up nitrogen, so you will have to fertilize. In general, the more finely divided the wood is, the faster it will take up nitrogen and decompose. Sticks won't hurt, but sawdust is a problem. Shavings could be a problem. If your soil is in the range ph 5.5-7.0, I wouldn't worry about it unless you are trying to grow something like blueberries, which need acid. If it's above 7.0, sulfur is a way to produce a more lasting acid reaction without affecting soil nutrients. |
