Prof. Samuel Fitzgerald, Ph.D.Epsom salt supports bell pepper plants with vital nutrients. Magnesium plays a crucial role in the creation of chlorophyll, leading to greener leaves. Sulfur plays a crucial role in the formation of important enzymes and proteins. These nutrients work together to strengthen plants during key growth periods.
Nutrient Functions
- Magnesium: Central to chlorophyll molecule formation
- Sulfur: Builds amino acids and vitamins
- Both: Enhance nutrient uptake efficiency
Solution Preparation
- Dissolve 1 tablespoon per gallon of water
- Use warm water for faster dissolving
- Stir thoroughly before application
Timing & Frequency
- Apply at flowering stage monthly
- Use early morning before heat
- Stop applications 4 weeks before harvest
Apply Epsom salt solutions judiciously. They reach the farthest leaf by being used in foliar spraying. Roots receive them quickly through soil drenching. During the flowering stage, I alternate these two methods of applying the salts every month. Always water the plants before using Epsom salt solutions to avoid shocking the absorbent roots with the concentrated preparations.
Avoid application mistakes. Never apply more than one tablespoon per gallon of water. It's possible to 'burn' roots by overusing, causing salt to build up. Never spray in the hot midday sun. Always check whether there is sufficient magnesium in the soil, and if in doubt, refrain from using it. I always conduct a soil test every season before applying anything.
Utilize Epsom salt and balanced nutrition with your plants. They work together but are not complete replacements for a balanced fertilizer. Use in tandem with calcium sources, such as crushed eggshells. My peppers had walls that were thicker with calcium, this way from the magnesium source.
Appropriately identify magnesium deficiency, indicated by yellowing between the veins of a leaf, while the veins themselves remain green. Older leaves will display the signs first. This is in contrast to nitrogen deficiency, where entire leaves are uniformly yellow. Correct diagnosis leads to the proper treatment.
Be sure to store Epsom salt appropriately between uses. Always store in a sealed container and keep it away from moisture. Label the container clearly to avoid confusion with table salt (e.g., Epsom Salt, or specify it is not for consumption). Keep Epsom salt in a cool, dark location. All these tips will help maintain its intended use and effectiveness for future growing seasons.
