How can i decrease my gardens PH?

I recently got my garden tested for PH which i used last year and my neighbors garden which he is just starting this year, both came out to 7.5 Alkaline. We probably shouldnt have been surprised because the valley we live in actually long ago used to be a limestone quarry. Our gardens are about 10,000sq ft. Mines in a square and his is in a rectangle. He used to have cows and i still have a few llamas so we both have what some might some consider fresh, and ';aged manure'; although i would think ';Aged'; means in some drying area but we dont do that. Anyways we are working together on this and sharing equipment and work so we can both feed our families. We are looking for some way to decrease our PH to about 6.5 or 7 would be good, because thats where our plants like. I grew some food in mine last year but it could have done better which sounds consistent with being outside the ideal PH range. I have heard of Aluminum sulfur or something like that and we really dont want to use that if its a chemical thats not natural. Also we looked into composting and that was to confusing and time intensive especially on our scale which we mostly do by hand and tractor but fixing tractors takes time and money, so we try to limit our use of those. Anyways we're a month away from planting which i know is not ideal but is there anything we can do to start the process of changing the PH but still be able to plant? Any idea will do. Oh i also heard about Manure tea and pine needles. And he has 50gallon drums and i have a few hundred feet of pine trees. So thats a option to if we need to. Let me know what you guys think, thank you!How can i decrease my gardens PH?
I use aluminum sulphate, although you can acidify your soil with sulfur, oaks leaves, pine bark and needles, peat moss, and use of an acidified fertilizer, etc. Your local garden center can recommend the best thing to use. If you want to go strictly organic, peat moss is your best bet. Aluminum sulphate is being used for my blueberries. It has done a good job.How can i decrease my gardens PH?

I read most of what you wrote here is an article for one state that talks about and shows a diagram to help you. Your best bet is to look up your areas extension from you local university. We have the University of Florida Extension Center that tells us almost everything we need to know, from what to plant when, and soil amendments to other details. Hope the link helps and good luck.
Depending on what you want to grow, tomatoes require more PH than other plants.

Some plants prefer acidic soils but most do better in a mid range. The best thing to help balance your levels is lime. It comes in several different forms, either powder (messy) or pelleted.



I'd research out what levels you need for what plants, strike an average and apply garden lime as directed on the packages.



We use a lot of leaf mulch which tends to be acid and we give almost everything a light sprinkle of the pelleted lime each spring. The pelleted stuff is more expensive but it is a lot less messy and usually requires fewer bags to do the same sq. footage so it balances out. I only needed one 40# bag of the pelleted vs. 4 bags of the powdered lime.
