Muriate of Potash-fertilizer question

Dean W. · 07-19-2008, 06:41 PM

I bought some Muriate of Potash today (0-0-60). Here's where I got it at Compost - Mulch - Soil Blends - Fertilizers - Herbicides and Insecticides . I have a few questions on it if anyone has experience with it. I bought 3-4lbs bags for $2.75 ea. How much do I need to mix for my bananas? Etc. Any advice on the product would be greatly appeciated.

What are you mixing it with? You should use a 3-1-6 ratio (NPK) including magnesium, iron, calcium.... Basically, you should use half the amount of nitrogen and 1/6 the amount of phosphorus as potassium.

The amount used depends on the size of the plants and current growth rate due to the climate. Its always best to use small amounts frequently.

A fruiting banana needs with a significant corm needs 1.5 lbs of potash per year. If your fertilizer is 0-0-60 and you have no other source of potash for your plants, you would use 1.5/0.60 = 2.5 pounds per year.

The trouble with most products sold as "Muriate of Potash" is that they are also 60% Chlorine. This dosage is toxic for plants. On the package you received, what are the percentages of chemicals listed on the label?

Solouble Potash 60%
Chlorine not more than 46.7%

Yikes!

It's a pool chemical, not a fertilizer. Over 2% Chlorine is too high for my garden.

See: Potassium chloride - Wikipedia, the free encyclopedia

Maybe I'll take it back then!

I thought I was doing good. They had some other stuff that was high in Potassium, but it was more expensive.

You were on the right track. Consider both Nitrogen and Potash when chosing fertilizer(s). For bananas, you would like a 2:3 ratio of N:K. For young plants in a pot, Alfalfa meal is a great choice.

I use Potassium Sulfate (Sulfate of Potash) on all my bananas and palms.
