The ph of my soil (in pots) is somewhat high; I know of materials commonly used to adjust it downwards such as iron sulfate or sulfur etc. Most of that usage requires you to mix it with the soil when you first start and most of it seems inappropriate to mix with water and add as you water. I wondered if using plain vinegar, diluted in water, would work.Has anyone ever heard of that? b1
i've never heard of using vinegar. where did the soil come from and what is the pH? the soil should be slightly acid, 6 or 6.5 should be fine and almost all potting mixes are balanced to be in this range.
Vinegar will work in some situations bearing on ther lime condition within the soil.This link will help you to determine this.If your at a 7 ph ya really should not bother but merely adjust the water given to plants to 6 and this will temporarily give you the 6.5 or so for the max uptake of nutes at waterings and ferts.Realy unless ya prepare alkaline soils(above 7.2) prior to using there is no quick and perminate solution.6.8-7.2 ph is considered nuetral in most situations,but if ya feel the need to try and lower check this lik inreference to lime/viniger use.You should make your own soil,very simple with a little research!There are alot of soil recipes out there to get one started with there own soil developement. http://www.ext.colostate.edu/pubs/garden/07727.html
