I'm trying to grow some Miracle Fruit plants. They need acidic soil. A lot of people recommend Scott's Miracle-Gro Miracid for them. Does anyone know if they sell it here or where I can get something equivalent?

Thanks!

Never heard of your fertiliser, but on checking it is basically NPK 30-10-10 which you can buy here. For the acidity side of things check your soil as most Thai soils are acidic. You should be able to find some Humic acid that you can add to the fertiliser.

Ammonium Sulfate 21-0-0+24S

provides lower soil pH when the plant picks up the Nitrogen,

leaving the Sulfate behind,

It costs around B400 per 50kg bag.

Not all fertilizer stores carry it because Thailand soil is typically acidic.

Limestone base soils have a high pH, where it becomes necessary.

Most plants require a little Sulfur, so if the soil is completely depleted,

you will see a dramatic improvement

Sulfuric Acid is also readily available...if you want instant results.

I found that 98% Sulfuric Acid is cheaper than 50%...one of those strange facts in the world.

If you want to pay the high price, Phosphoric Acid is more useful to the plant

while lowering the pH until it is consumed.
