Soil ph Won't Go Down?

Dolomitic lime tends to be slow to change the soils pH due to the size of the particle and it more suitable for long-term growing and/or agricutural such as a garden or lawn. The smaller particle size of processed "fast lime" is better suited for container grown plants and is released relatively quickly while still offering the benefits of micronutrients such as calcium and magnesium. Often it is available at Lowes or Home Depot in smaller bags. Usually very little is needed (as little as a few tablespoons/container) and begins to breakdown in only a few days or wks. Remember, limestone is basically a processed rock and as such is relatively insoluble compared to fertilizers or other amendments. Using more than needed will not make things happen quicker, using the correct type will.

i'm assuming your plant is already dead from using 1/4 bottle of ph up on it :P

mix some lime in your soil, should help.

MG Organic Potting Mix comes out of the bag around pH5 or so.. at least mine did. I limed it though and it holds at 7 or just above. Let's me pour pH6.5 nutes without concern.

1 cup=16 tablespoons. 1 cuft=approximately 7 gallons. You say 1 tablespoon per gallon and then follow by sayinng 1 cup per cuft, which would be 16 tablespoons for 7 gallons of soil. More than double the 1 tablespoon per gallon you first reccomend. Which is it? :?

lol The scary thing is I've done both. I guess there's a wide margin to play with.

Maybe I should have said 2 tablespoons per gallon. 1 cup per cubic foot is good. I rarely mix 1 gallon at a time. :/

Internet parrot at its best...hey Spackler, you may want to rethink your aforementioned thoughts on the different types of lime...you seem to be a bit flip-flopped and lost...:shock:

Quick pH adjustments happen in hydro with res changes. Quick pH adjustents in containers only adds insult to injury....
Dolomite is the lime you want to use in your container mix, at least a 50/50, dolomite/calcitic mix. Save the hydrated, 'fast acting', lime for us farmers....

Miracle grow organic soil from walmart. I check the runoff in two gallon pot and it is red ph with liquid indicator.
I flush ten times

, adding a quarter bottle of ph up base solution 8 oz bottle, and its still reddish orange? I'm about to pour the rest of the bottle in with a gallon of water. It takes a few drops to change the water but a few ounces and the runoff barely changes at all. Oh and I would have no clue where to get bat guano so don't suggest that lol.

As pointed out to me, the title should say that the ph will not go up.

Not much left in the soil after that deluge. cal your ph meter or get another to double check.
