Sjeffery you can apply Mg, to a well watered container, a partially watered container, a moist container, It doesn't matter. - Millet

SJeffery, I usually water all plants at least a little & wait a minute & then fertilize, esp when dry. Epsom salts is not as harsh or burning to roots as ferts. I give them less per gal in winter, & not every watering. In summer, I always add mg to water when fertilizing as my fert doesn't have it. mg helps take up nitrogen too.
You came to the right place for help, advice & opinions!

See Millet's comment just above here! That should answer it for you.

I am adding to my old thread because I want to know how much epsom salts i should add to my fertilizer water that I use every time I water my citrus. I mix it in one gallon batches.

Valenciaguy, read back. Millet said at least twice, to mix 1 tablespoon epsom salt per gal water

yes i do remember that but he said to use that formula when the tree has a magnesium deficiency, but i just want to add it too the water i use every time.

Sometimes ppl use mg everytime they water. I think Laaz (correct me if I'm wrong) said that he uses it every time he waters. I use it when I fert & in between except in summer when they get real rain water.

Plant growth is most vigorous and problem free when all nutrient elements are synchronized. An excess of one nutrient element frequently influences the availability and absorption of other nutrients. There are several key element relationships that must be considered. For example the ratio of calcium to magnesium available for plant growth is very important in containers. If calcium is excessive magnesium absorption is reduced and if magnesium absorption is excessive calcium absorption is reduced. The calcium to magnesium ratio should be 2:1. When soluble sources of elements are used, they must be applied frequently in order to maintain a reasonable level available for plant growth at all times. Nitrogen, potassium and magnesium are the elements most readily leached from a container growth medium. Therefore, they are the most difficult to manage and require the greatest attention or monitoring. Phosphorus, calcium, magnesium and the micronutrients, are best added to the growth medium at time of mixing. Enough of these elements to last a year or more can be added during mixing. I add S. T. E. M., Dolomite (a slow release form of Magnesium and calcium) directly into the growth medium when it is first blended. The addition of dolomitic limestone, to the growth medium should provide both nutrients, although extractable calcium and magnesium can often be insufficient. Water soluble sources of calcium and magnesium should supplement the fertilizer program whenever levels are low. Levels of 60 ppm calcium and 30 ppm magnesium can be used in constant feeding programs. Irrigation water may provide these nutrient levels. If so there is no need to supplement them. Because I am growing Citrus I add phosphorus with my water soluble fertilizer. Epson salts can be added if a magnesium deficiency is noticed. - Millet

I use it about 3 times a year on my potted plants. My inground get it about 6 times a year as do my palms & lawn.

I added dolomite lime when I treated the CHC so I should be good then. A couple of days ago I just used some Epsom salts and sprinkled it in the pot is it ok to do that every few months?

P.S. This is mostly regarding my clementine because I think it has a def. and it gets all the macro NPK and most of the minors including iron and zinc(also foliar sprayed it with iron). Then i read that it could be mag. and that sometimes with out enough the roots can take up other nutrients.

If you did want to add Magnesium on a continual basis (I wouldn't) the rate would be in the area of 30 to 60 PPM . - Millet

I apologize Valencia, I could swear I heard several ppll here saying that they ALWAYS add mg when they fert esp in summer..... ONLY when they fert.... but I was wrong. Sorry 'bout that.
Also sorry I thought Laaz added mg every tiime he watered.,,.. I thought he said that once, as I thought many other ppl did too. I have done it & it has always worked fine for me. (almost all times)

thats ok Patty I think i try it just to see how it helps but only on one tree first.

Derek, I'll change my mind a bit. I used to call on all the carnation flower growers in Colorado (There was 87 wholesale carnation greenhouses) selling them fertilizers, insecticides and greenhouse supplies. Carnation growers added STEM and Magnesium with every watering in small levels along with NPK. All ingredients were added through an automatic system.

I believe Magnesium could be added at least every other time you fertilize at a rate of 30 PPM. Epson Salts is 15 percent Magnesium, therefore 30 Percent PPM solution - 3/4 gram of Epson Saalts per gallon

I think I am going to try that, I use fert. ratio that is suggested for every water which is a very weak amount. So ever other time I mix up a batch of it I am going to add the magnesium.
