Skip to contentIn&nbsp;chemistry,&nbsp;pH is a scale used to specify how&nbsp;acidic&nbsp;or&nbsp;alkaline a substance&nbsp;is. Acidic solutions have a lower pH, while alkaline – or basic – solutions have a higher pH. If the pH level is exactly 7, such as that of pure water, it’s neutral. If your soil is too alkaline some plants won’t grow well so you’ll need to learn how to lower pH in soil fast!Different types of plants need different levels of soil pH to survive and thrive. And although soil pH varies from region to region and one garden to the next, most plants need a pH between 6.5 and 7. But there are other plants, such as flowers like azalea, marigolds, or heather, and fruits and vegetables such as blueberries, potatoes, and peppers – which need and thrive in slightly acidic conditions.Once you’ve decided what to plant or decided which plant may benefit from lower pH it’s best to verify the soil’s current pH level before making any adjustments. This will give you the baseline to start making amendments from.Table of ContentsIn order to correct alkaline soil, you will typically need to introduce a source of acid. You can add compost, manure, or organic soil amendments like alfalfa meal to increase the nitrogen level of the soil which will also gradually decrease the pH.The speed of the conversion is dependent on the particle size of the sulfur, the temperature and the degree of moisture of the soil, and the amount of bacteria present.Sulfur will only work during the warmest months of summer when bacterial activity peaks. It can therefore take up to several months for this method to decrease the soil pH value.Elemental sulfur is the best choice for lowering the pH of very dense soil, such as soils with a heavy clay component. Also by adding organic materials such as manure to heavy clay soils will help it become more workable, and as a bonus the manure will gradually lower the soil ph naturally.&nbsp;As it takes so long to act, elemental sulfur is best introduced at the end of the last planting season.What is the fastest way to lower pH in soil? – While there are methods that will make the soil more acidic very quickly, their results may vary, and in some cases, they may over-correct the soil pH and do more harm than good. The following methods will lower the soil pH quicker than elemental sulphur but as they are fast acting, you should add them to the soil in measured doses.While it’s a well-known myth that coffee grounds are a quick fix for lowering soil pH, in fact, most of the organic acids in coffee are water-soluble coffee and flush out into the brew. Used coffee grounds have a pH of around 6.8, which is so close to neutral that they won’t lower pH much; however, they do add a little nitrogen, so they can help reduce pH over time, just like manure or compost.Freshly ground or brewed coffee has an average pH of about 4.5, depending on the region in which it was grown. So if you need to drop soil pH more quickly, try watering your plants with leftover (cold) coffee that is diluted 50-50 with water.&nbsp;This method works especially well for smaller volumes of soil such as for houseplants or container vegetables.Vinegar is a kitchen staple because it has a wide variety of uses; it can be used as a condiment, to add flavor to cooked dishes, and even to clean sinks and counters when the cooking is done. This potent liquid is also useful to gardeners, and it can be used to naturally adjust the pH level of soil without the need for harsh, commercially manufactured products.Vinegar can be sprayed onto the soil or introduced through an irrigation system. A cup of vinegar mixed with a gallon of water is ideal for plants like azaleas and rhododendrons. Vinegar can be bought in bulk much cheaper than small bottles like this from Amazon.One of the quicker-acting acidic soil additives is aluminum sulfate; it produces acidity in the soil as soon as it dissolves, which is basically instantly as long as moisture is present. If you need to urgently lower the pH level of your soil, aluminum sulfate is a great choice.Mix around 5lbs of aluminum sulphate around the base of the plant you want the soil ph lowered to reduce the pH by around 1 unit. Always check the dosage on your label before application. Have a look at this to see if it works for you.A common ingredient in manyslow-release commercial fertilizers, sulfur-coated urea is a fairlyquick-acting soil additive. It can lower the pH level of the soil considerablyover time, yet will produce some effect within a week or two of beingintroduced.If you were already planning to fertilize the soil as well as decrease its pH, simply choose a fertilizer that contains urea; the sulfur-coated urea content does vary from one brand of fertilizer to another, so remember to consult the mixing instructions to determine the proper amount to use.A good choice for heavily compacted soil with high clay content, iron sulfate, and aluminum sulfate relies on a chemical reaction to create acidity in the planting beds, making it less dependent on temperature conditions than elemental sulfur which relies on a slower biological reaction to begin any changes in soil ph.Both Iron sulfate and Aluminium sulfate act faster than elemental sulfur and can significantly reduce pH in as little as three or four weeks; therefore, it can be used during the same season you decide to plant acid-loving plants.Iron sulfate can leave rusty stains on clothes, so it’s best to wash any clothes that have come into contact with them separately to avoid damaging other items; they can also stain cement surfaces such as patios or sidewalks.If you have a smaller area of soil you would like to treat, take a look at this – It says it treats 1000 square feet which seems a lot for 4lbs – I would still apply one dose at a time and check your levels again afterward.In summary, I would say that the most important thing to do first is to measure the soil pH. – I would recommend you or fill a bag with your soil and take it to your local agricultural shop for soil analysis.If you’re not sure which pH meter to buy – I can only say avoid cheap meters – usually the more accurate meters are more than $30, the most accurate pH meter I have ever used is theWhen you get your results back you can begin to amend the pH in whichever way you choose. The coffee and vinegar methods would be ok in small potted areas but not really realistic for large areas.To lower the pH in larger areas I would use elemental sulfur if I wasn’t in a rush- but usually, you do want the benefit within that growing season. In this case, I would choose Iron Sulphate as my first choice (this will help to reduce aluminum toxicity in the soil) and if I couldn’t get that then my second choice would be Aluminium Sulphate.If you would like more about soil, its profiles, and horizons, take a look at my article for more info.Thanks for reading and good luck- Richard.Further reading:https://hortnews.extension.iastate.edu/1994/4-6-1994/ph.htmlhttps://www.extension.purdue.edu/extmedia/ho/ho-241-w.pdfThis was helpful as my soil is alkaline and Ill try the 3 methods Here to try and get my ph to around 7 . Thanks for the info.I have garden . Check the PH in the soil and found that the PH level is around 8Should I lower it by adding vinegar water solution?I have 12 tomato plants already in the ground for 2 weeks. I’m a novice gardener and just learned they like acidic soils. I bought a tester and found my soil has a ph of 8 to 9. I will try the vinegar first and give it a week or so. I will let you know what happens. Many thanks.good article. will try vinegar. thanksHi Richard,How soon after using vinegar or coffee, should soil pH be tested?Thanks,MariaHow much vinegar/water would you apply to each azalea plant? how often should it be applied? if you use the vinegar how and when should you use iron sulphate to get the ph lowered permanetly? great article, thxThank you Richard.MariaHello Richard, I take care of a common area, an island in our cul-de-sac. For the winter I planted annual rye. In June I hope to seed it with Argentine Bahia. The 1700 Sq. ft. island has no watering system. So I chose the Bahia grass. The soil test done by UF in Gainesville showed a PH level of 7.7 down from a higher level a year ago. What is the best fertizer to use to lower the PH level before seeding in June? Ammonium? Iron Sulfate? How much would I need for the area?HarmenCan Iron Sulfate be safely used in an organic vegetable garden? Would it be better to use ammonium sulfate?Hi Richard,My Soil PH is 8.72 and I want to make it 4.5.Any idea which is the idea method to reduce it and keep it at 4.5 for longer duration.Please note there is nothing growing on this land now and it will be unused for next 3 months, if required we can keep it free for next 1 year or so.We want to start blueberry cultivation. Do suggest any method and we will love to follow it.ThanksGreat article –I found out my soil is 7.5-8 AFTER I already planted my veggie garden, Raised beds newly filled with 1/3 purchased compost:1/3 vermiculite:1/3 coconut coir.Plants turning yellow. pH too high and very little nitrogen.How do you amend after the facts???:'(THANK YOU!!!I have already planted tomatoes, and received my soil results today. My soil pH is 7.6 for a quick result, would you recommend I mix solution of vinegar/ water @ 50/50 and water the soil around each plant ? Maybe sprinkle coffee grounds around each plant as well ?
