If I don't like red-lava-rock leaving red iron-stains on the leaves, I just take them off... but I can't undo the damage of gypsum that drop the pH level with its 17% sulfur, or lime that shoot up the pH too fast. Taking off rocks or pebbles takes 1 min, compare that to hours scraping off cow manure .. the damage was done too fast & could not reverse that cow-manure-disaster. The advantage of pebbles/gravel is it's naturally released whenever acidic rain hits it ... so the release is controlled gently by Nature, rather than us foolishly dumping all at once. I take magnesium oxide daily with lemon juice, only 1/2 teaspoon is enough to have a MAJOR laxative effect in human. One Amazon customer complained of explosive diarrhea since he took 1 teaspoon. Rose is smaller than a human, so 1/4 teaspoon, or just a touch is enough to UP the pH-level ... it's very alkaline. Calcium is just the opposite: it's constipating, tense up muscle & contract heart ... versus magnesium is laxative, relaxes muscle, used as IV to treat heart diseases. Taste-wise, Magnesium oxide have zero salt, versus salty & bitter Epsom salt (magnesium sulfate). When I gave Angel Face rose too much gypsum (calcium sulfate), its leaves crinkled & curled up .. plus it lost the scent. Same with Bayes Blueberry: the foliage became ugly & dull. Too much calcium tense up and contract muscle in humans, which explains why leaves tense up .. and pucker up instead of flat & relaxed like normal leaves. OLDER leaves crinkled & curled up is typical of magnesium deficiency. YOUNGER leaves crinkled & curled up with yellow blotches is boron deficiency. Both are induced by too much calcium. Too much calcium also drives down potassium, resulting in less blooms & faded color. Calcium can be from gypsum (calcium sulfate), or lime (calcium carbonate), or hydrated lime (calcium hydroxide) which is added by municipals to treat tap-water .. this form of calcium shoots up the pH of tap water, causing magnesium and boron deficiency. Too much calcium drives down potassium, thus roses become stingy with tap-water high in hydrated lime. Too much calcium also cause balling of blooms: petals bunch-up, rather than relax and open-up. Below is a picture of boron deficiency, manifested as crinkled & curl-up YOUNGEST leaves, too much calcium induces boron deficiency." God bless you Straw....you are a gem. So....... I don't have to go to a chemical store to buy MgO2. I can buy it from a pharmacy I guess but they are selling it in the form of capsules mostly and that is expensive to as it comes with a brand name. But I will get it today because day after tomorrow morning I will be leaving Islamabad for 22 days. So I must do it before I leave. BTW, also need to keep some Monopotassium Phosphate in my stock. Just in case I see a potassium deficiency in any rose (which I don't expect anytime soon). Thanks a ton Straw.
