In the nutrient supply of hydrangeas, Epsom s alt is the missing piece of the puzzle for specific deficiency symptoms. Used preventively or as needed, Epsom s alt guarantees lush green foliage and a soil pH value suitable for hydrangea. Read how to properly use Epsom s alt for hydrangeas here.
How to use Epsom s alt on hydrangeas?
Epsom s alt helps hydrangeas with magnesium deficiency and regulates the pH value of the soil. If there are deficiency symptoms, apply 50g of Epsom s alt granules per root slice in spring or add liquid fertilizer to the irrigation water. In case of acute magnesium deficiency, use 1% Epsom s alt solution as foliar fertilizer.
How can I use Epsom s alt on hydrangeas?
Epsom s alt is the colloquial name for magnesium sulfate. Hobby gardeners use Epsom s alt as a special plant fertilizer for hydrangeas to prevent an impendingmagnesium deficiency. An undersupply of the trace element causes yellow leaves with green veins. Epsom s alt ensures a complete supply of magnesium for hydrangeas, the central building block in leaf green, known in technical jargon as chlorophyll. How to Use Epsom S alt as a Maintenance Fertilizer:
- In April, sprinkle 50 grams of Epsom s alt granules onto the root disc, rake in and water.
- Alternatively, add Epsom s alt liquid fertilizer to the irrigation water according to the manufacturer's dosage instructions.
- Repeat Epsom s alt fertilization in summer if necessary.
How can Epsom s alt correct acute magnesium deficiency?
If a hydrangea already has yellowed leaves, maintenance fertilization with Epsom s alt is not enough. Valuable time is lost until the nutrient makes its way through the roots to the leaves. Targetedleaf fertilization supplies the leaves with the urgently needed magnesium in real time. How to do it right:
- Dissolve 10 grams of Epsom s alt in 1 liter of water.
- Pour fertilizer solution into a spray bottle.
- Spray hydrangea leaves on the top and bottom.
- Important: Apply Epsom s alt foliar fertilization when the sky is overcast and temperatures are above 15° Celsius.
How can I also use Epsom s alt on hydrangeas?
Hadern hobby gardeners with too high a soil pH value use Epsom s alt as a problem solver. For spectacular blue flowers, hydrangeas rely on an acidic pH value of around 4.5. For pink, red and white flowers, a pH value of around 5.5 is mandatory. How Epsom s alt creates ahydrangea-friendly soil environment:
- Determine the pH value with a test set (€17.00 at Amazon).
- Use Epsom s alt from a pH value of around 7.
- Dissolve 150 grams of Epsom s alt in 10 liters of water and apply to lower the pH value by 1 point per square meter.
Tip
Watering hydrangeas with rainwater
Conifers are strong magnesium consumers. Annual maintenance fertilization in spring effectively prevents yellowing needles. Simply sprinkle 50 grams of Epsom s alt per square meter, rake in and add water. If thuja, fir and cypress already suffer from yellow needles, administer 100 grams of Epsom s alt per square meter. Foliar fertilization with a 1 percent Epsom s alt solution immediately eliminates the magnesium deficiency.
