I just wanted to relate how wonderful Epsom Salts (magnesium sulfate) is for plant culture. About 3 months ago I sprinkled the granules around my small stunted mango tree that is 17 years old and has yet to produce fruit, on my sugar apple tree (Annona squamosa) that does produce fruit but are small, and on my young Longan trees, and watered in generously. It was a miracle! All the trees’ leaves turned a dark green and look very healthy. The sugar apple tree is producing large fruits with no bugs attached and no white flies evident; the mango tree has healthy looking leaves and I’m sure it will finally produce fruit next spring; and the little Longan trees are looking great and growing.
Our soil is composed of limestone which is rich in calcium. And come to find out, high levels of Calcium, as well as Potash, induce deficiency of Magnesium in the soil. In other words, high levels of these block absorption of Magnesium by the roots. Magnesium is an essential building block of the chlorophyll…without it photosynthesis will not occur in plants. And also come to find out, Magnesium can be sprayed on the leaves as a quick fix as it is easily absorbed by the leaves.
