... of potassium for vegetable gardens?
Sul-Po-Mag, 0-0-22. Or sulfate of potash, 0-0-52.
Got your original reply in my email, and wondered at it.
I found a bag of bone meal and two boxes of blood meal in the waaaaay back of the shed, and was looking for a source of K to go with the N&P.
So I suppose I can find the suggested products at a garden store?
Wood ash too. Be careful depending on what your pH is, though.
That's because my eyes were seeing potassium but the brain was thinking phosphorus!
Yes, most of your nursery and gardening stores should probably at least have Sul-Po-Mag, 0-0-22. I can't honestly say that I've seen sulfate of potash, 0-0-52, since the second choice is usually muriate of potash, 0-0-60. Muriate of potash isn't considered organic despite the fact that the recovery process is identical to what is used for sulfur.
woodash....up to 5 gallons per 100 square feet
Mulched Banana skins?
Great suggestions all around, thanks!
Martin, I could only find the muriate of potash when I went to the local garden center -- but their focus is not organic. The package looked old and like it had been on the shelf for a couple of seasons, so I don't know if it is any good. There was no freshness date.
As banana skins are plentiful here (got bananas on sale for 19 cents a pound), I think I will just bury them as is in the garden. I used to do that B.C. (Before Composting), and it worked quite well.
There is also plenty of wood ash, but I am wondering if that would burn plants. Any idea, Meloc?
Muriate of potash doesn't have a shelf life. It will last forever but will cement itself into one solid chunk if allowed to get too wet and then dry. I'll often add about a cup for each compost tumbler batch. That's from a bag which is 4 or 5 years old. If applying 0-0-60, follow instructions and do not exceed by much. That's the "salt of the earth" and the earth doesn't need much of that seasoning!
