Does anyone know how long before a rain storm STEM will be effective? I just bought some from Mr. Texas, but it's supposed to rain this weekend.

Thanks,
Phillip

Manganese is available @ most all garden centers- you can get it at lowes or home depot , comes in a small 5# bag.

Manganese is an essential trace element for plants and just about anything else that is alive, palm trees especially. A good quality fertilizer should have a trace element package in it therefore no need to add any extra.

There are other folks here on this forum that are chemical wizzards and can chime in and tell you more than me but if not , this should get you started.

Really? I've never seen it.

I'll can sell you a pound of Scott's STEM(soluble trace element mix) for $5 plus $5 postage plus $1 paypal fee. It will cure all trace mineral deficiencies. And 1 pound is a huge amount. I had to buy 25 pounds to get a sack. I'm not making money on this sale! I use 1 teaspoon per gallon and spray it on to keep all my citrus dark green every time I spray for bugs. I've sold a pound to several forum members including Joe Real. I have at least 20 pounds left.

I'll send a pound to anyone on the forum

Just sent you a PM. Hope you still have some!

Phillip,

If the STEM is in the soil for a few hours, it should become quite rain fast (assuming your soil has some cation exchange capacity -- is not pure beach sand), at least the cationic elements (Mg, Mn, Zn, Fe, Cu, etc.). Boron, molybdenum, and sulfur in the form of sulfate are leachable from the soil, but I'd think your plant would take up quite a lot of them in a day or two. And even the leachable stuff shouldn't move out of the root zone of the plant unless you have a very shallow root system or a very heavy rain.
