2 months agoAsk a Grow Question I’m re-amending some soil for pots. I screwed up and got it too “Sweet” the ph is at 7.3. what can I use to buffer that down some? I’ve heard sulfur can be touchy and I don’t need to move it much. Suggestions? TIA

Peat moss, alfalfa or cottonseed meal, and chicken manure are good options.
You are wise to be cautious of sulfur it can turn to Hydrogen Sulfide when saturated or flooded which can kill your roots. It is helpful with really clay dense earth though. Usually you would add it at least a year before planting as well.

@plant-daddy yeah I have more soil to do I think I’m gonna set this aside for a while and do another batch. Got a little heavy with the lime 😆

Compost is also an option. As organic matter breaks down it increases acidity. If I’m remembering correctly the microbial life in compost prefers acidity to help break down the organic matter, and will buffer the environment to be conducive to what they need. Consider adding some aeration to offset the “heaviness” of the extra compost if you go that route.

You can try spraying with deluted white vinegar, it will act as a ph down and feed the microbes
