how much sulfur to use for blues

Posted by riverman1 (My Page) on

Today I bought some Epsoma organic sulfur for acidifying soils.

The label says to use 2.5 cups for established plants which seems like WAY TOO MUCH.

My soil pH is in the 6 range now and I would like to bring it down a bit. Any suggestions?

Thanks guys.

Somewhere I was told a half a handful a couple times a year per plant.

That's kind of what I recall hearing too. I did a search on the topic but the recommendations seem to be all over the place from a couple tablespoons to several cups per plant!

well... It depends on where you live... For example - we don't need ANY sulphur here at all... but our soils PH range is generally from 5 to 6.5.... I just throw normal lawn fertilizer on them and they do great.

What does your soil test say for soil PH?

Thanks

As John said it really all depends on your native soil OR what you have them growing in. If they are in pots or raised beds you have to be a bit more careful. Here I give each plant a couple handfulls every spring just scattered about.

Thanks guys........as I mentioned in the orginal post, my pH is at about 6 now. I guess I will go ahead with a few handfulls and see how it goes.

thx again.

Riverman,

It has more to do with your native soil PH. The soil will always try to return to that state.

If your PH is at 6 - why would you add any Sulphur? That's plenty acidic for anything that needs acid soil....

If you are really worried about it - skip the Sulphur and just go with something like an Organic Azalea/Camellia/Rhododendron fertilizer... Epsoma makes a fine organic fertilizer for Acid loving plants.... I think it's called Hollytone or something like that...

Thanks

The native soil is around 7, my bark/peat mix measures at about 6.5. My well water is also at about 7......and I'm pouring gallons and gallons on it all summer. As you guys know, blues ideally like a soil that is in the 4.5 to 5.5 range. My plants are just barely showing some leaves and I haven't fertilized yet and mostly wanted to give them just a little bit of a push toward acidity as I move toward summer. When I do fertilize it will be with either ammonium sulf or an acid loving organic fert of some kind.

Thanks again...........

RM
