Lower the pH of my garden soil
Comments (12)Excellent... thank you, SO. I think chemistry was my worst subject in high school, so having you summarize that simply and plainly is much appreciated! No danger of getting our soils anywhere near 6, eh? lol We must have excellent buffering qualities (hope I'm using that term correctly), though, because the efforts to lower pH here seem to be sticking better than areas such as daninthedirt is speaking of (great username, by the way, Dan). I also have a rather easy time lowering water pH for our aquarium fish; half distilled and half dechlorinated tap water keeps it in a comfortable range for them without having to purchase adjusting chemicals. (We're now on the river water pipeline that goes into town; well water was much, much worse and I could only use a small amount mixed with the distilled.) We're rural in the Humboldt area, but we have family who is mixed farming the Young/Allan area. :) Prairie Garden Seeds is in Humboldt here and I met Jim and his family briefly when I picked up a seed order last year. Nice folks. I should ask for a tour of the seed gardens someday. One more question. Our garden has flooded before. How long does it take for the iron to then get back to an unavailable state after such an incident? So as not to hijack crabbygardener's thread any further (sorry about that), I'm going to spin off with a new post over in the soil forum regarding my question about zinc and copper.

Comments (4)Yes to the sulfur, if the plants aren't already established in the ground (veggies) incorporate the S as far ahead as possible, in your cold soils you not get a lot of pH shift until next Summer or later. If you can, get a soil sample for pH before the S is added and again in the Fall to see what has happened. Getting a recommendation from the lab for how much S needs to be added/100 or/1000 sq. ft. to drop the pH will be very useful to you and important. BTW, if your S is surfaced applied it will take even longer to do it's thing as it has to work it's way down into the soil through cracks and with rainfall. Keep in mind that when it comes to lowering the pH very much to be patient and that soil likes to return to it's own equilibrium, meaning in your case, it'll want to push the pH back up from the S addition(s) over time....See MoreAcidified the soil 10 years ago, is it still acid?
Comments (13)Lot of misinformation going on here....:-)) Acid planting mix can certainly help to achieve a proper degree of soil pH for some plants but it is unlikely to be a permanent condition if you use it in an inground planting situations - much more effective long-term if used in a raised bed or in a container situation. 8-10 years is a long time so I'd guess that current soil pH is no longer very acidic but you will not know for sure unless you test. And retail soil pH test kits are NOT worthless.....in fact, they are about the only accurate soil test kits there are on the retail market but you must use them with distilled (not tap) water. SoCal soils are often on the alkaline end of things but that is very different from sodic - if you have concerns about that then a professional soil test is advised. And finally, most plants are adaptable to a range of soil pH so that does not necessarily limit what you can plant in your existing soil conditions. Just avoid those that prefer the quite acidic conditions like the blueberries. Many fruit trees grow very well in SoCal soils so check and see what neighbors might be growing or what's sold at your local nursery....See MoreSulfur calculation to lower soil pH
Comments (8)I am using agricultural sulfur to lower pH around our blueberry shrubs, for 14 years now, so I know how to apply and also how to measure pH. Sulfur is not an acid, it must be metabolized by bacteria in the soil, and slowly converts to sulfuric acid, over time, typically one year. The soil pH will be variable during this time, and after all the sulfur has been used up, it will very gradually rise, due to the effect of the surrounding soil and subsoil. If you are watering your roses with tap water that contains calcium and/or magnesium, then the pH will rise over time. Soil pH can be measured by taking a soil sample, mixing it with distilled water, and filtering the mixture to get about one teaspoon of filtrate. This sample is then mixed with several drops of bromothymol blue indicator, and the resulting color indicates the pH. Blue = pH 7.6, or higher. Yellow = pH 6.0, or lower, and varying shades of green mean the pH is between 6.0 and 7.6....See Moregirlfromthegarden
