Magnesium-deficient plants often display yellowing of their leaves, rather than their gorgeous blooms.Epsom salt doesn’t just provide magnesium; it also helps improve nutrient absorption. The magnesium facilitates the uptake of vital nutrients like nitrogen and phosphorus. With Epsom salt, you’re ensuring your hibiscus isn’t just getting nutrients, but making the most out of them.Adding Epsom salts to soil that already has sufficient magnesium can actually harm your soil and plants, such as by inhibiting calcium uptake. Spraying Epsom salt solutions on plant leaves can cause leaf scorch. Excess magnesium can increase mineral contamination in water that percolates through soil.A good fertilizer ratio for hibiscus is 12-4-18 or a “high bloom” water-soluble fertilizer. Slow-release granular fertilizers, like Osmocote, can be used in combination with water soluble fertilizer when irrigating. Magnesium sulfate, also called Epsom salt, gives hibiscus foliage a good dark green color.
