1. Soil Application (For Established Plants)
For mature geraniums, adding Epsom salt directly to the soil can provide long-lasting benefits. Here’s how to do it:
- Step 1: Measure about 1 tablespoon of Epsom salt per plant. For larger or potted geraniums, you may need to increase the amount slightly.
- Step 2: Sprinkle the Epsom salt evenly around the base of the plant, avoiding direct contact with the stem to prevent any potential irritation.
- Step 3: Gently rake the soil to help the salt mix in, then water the plant thoroughly. This will help the magnesium and sulfur dissolve and penetrate the soil for maximum absorption.
2. Epsom Salt Fertilizer Solution (For New or Young Plants)
For younger geraniums or those in containers, a diluted Epsom salt solution can provide a gentle nutrient boost. Here’s how:
- Step 1: Dissolve 2 tablespoons of Epsom salt in 1 gallon of water.
- Step 2: Stir the solution well to ensure the salt is fully dissolved.
- Step 3: Use this mixture to water your geraniums. Apply it once a month during the growing season (spring and summer) to help support growth and blooming.
3. Foliar Spray for Quick Absorption
If you notice your geraniums aren’t blooming as expected or seem to be lacking vibrant color, an Epsom salt foliar spray can provide a quick boost to your plants. Here’s how to make and use a foliar spray:
- Step 1: Dissolve 1 tablespoon of Epsom salt in 1 quart of water. Stir the solution well.
- Step 2: Pour the solution into a spray bottle.
- Step 3: Mist the leaves and stems of your geraniums, being sure to cover the entire plant.
- Step 4: Apply in the early morning or late afternoon when the sun is not too intense to avoid leaf burn.
This foliar feeding method allows your plants to quickly absorb the magnesium and sulfur through their leaves, which can help stimulate growth and flowering faster than soil application alone.
Additional Tips for Growing Lush Geraniums
While Epsom salt can certainly work wonders for geraniums, there are a few other key care tips that can help your geraniums thrive:
- Proper Sunlight: Geraniums need at least 6 hours of direct sunlight daily to bloom well. Make sure your plants are getting plenty of sun, whether they’re in the garden or in pots.
- Watering: Geraniums like to be kept moist but not waterlogged. Ensure your plant has good drainage to prevent root rot, and water when the top of the soil feels dry to the touch.
- Deadheading: Regularly remove spent flowers to encourage more blooms. Pinching off dead flowers will also help your geraniums focus their energy on new growth.
- Fertilization: While Epsom salt helps provide essential nutrients, regular fertilization with a balanced plant fertilizer will give your geraniums the nutrition they need to grow strong and bloom profusely.
Conclusion
The secret to lush, vibrant geraniums lies in the simple but effective use of Epsom salt. By incorporating this natural ingredient into your plant care routine, you can boost flowering, improve root development, and ensure your geraniums stay healthy and green. Whether you apply it directly to the soil, use it in a foliar spray, or create a nutrient-rich solution, Epsom salt can work wonders in bringing out the best in your plants.
With a little care and attention, your geraniums will reward you with gorgeous, colorful blooms all season long. So, next time you’re tending to your garden, sprinkle some Epsom salt and watch your geraniums flourish like never before!
