Boost Hydrangeas for Winter: Apply Foliar Feed in Early October
Gardeners, take note! A timely foliar application can help your hydrangeas stock up on essential microelements, survive the winter, and produce stunning flower heads next season. This simple process involves treating the plants in early October, just before the cold sets in.
To begin, dissolve 2 tablespoons of potassium monophosphate in 10 litres of water. This solution will serve as the foliar feed for your hydrangeas. When applying, ensure you cover both sides of the leaves for maximum absorption. This thorough treatment will help the plants store vital nutrients for the upcoming winter and bloom season.
The ideal time for this last feeding of the season is in early October. This timing allows the plants to utilise the nutrients effectively before the ground freezes, setting them up for a healthy winter and a vibrant spring bloom.
By following this foliar application advice, you're giving your hydrangeas the best chance to thrive through the winter and produce lush flower heads in the next season. It's a simple, yet effective way to care for these beautiful shrubs.
