It didn't help that the last quarter of last year was so busy, I hardly stepped out into the garden. Besides, Petunia has never been patient enough to wait till she has understood everything before she launches herself into an escapade of the non-physically-challenging sort. Most times, I figure that things will get clearer as I go along... and besides, learning requires mistakes no?
Oh well... this time, my mistake is a big, big one indeed!! Oh... woe is me!!
See... I somehow understood that magnesium was necessary for something that a plant does (whatever that might be)... and since none of the fertilizers that I used in the past had any stated magnesium, I went and assumed that magnesium would be the missing nutrient. Now of course LL would have gone and done a soil test. But Petunia conveniently tossed that notion out the window and went ahead to augment her garden. Being rather busy with proper work, not the fun gardening sort of work, I went through my garden dispensing magnesium like I was The God of Fortune dispensing gold. I gave out A LOT, A LOT, A LOT of magnesium.
And many plants simply fell over. They look like yesterday's stir fry.
Alright, now I know that too much magnesium takes out nitrogen from the soil and interferes with the plant's ability to absorb phosphorus. How does magnesium take nitrogen from soil? Dunno. How does magnesium prevent a plant from taking in phosphorus? Dunno. Whatever it is, my plants are starved and now I worry that if I add A LOT, A LOT, A LOT of something else, then my poor plants will really have to become yesterday's stir fry.
Oh... does anyone know what to do to make those sprigs of stir fry stand up again?
