Hydrangea macrophyllas are spectacular in bloom and are show stoppers within the landscape. Pink or Blue, this early summer blooming shrub will last for weeks.
People are always wanting the hydrangea color they do not have. It is much easier changing the color from pink to blue rather than vice versa. So take a good look at your lovely hydrangea plants and determine if the color is appropriate for the space. The two hydrangea shrub pictures are of the same plant, but installed in 2 different locations.
This large hydrangea shrub, probably Nikko Blue, has bloomed this color for many years. 2 years ago a cutting was taken and planted on a different property. Below is the bloom of the cutting.
Quite a difference in color.
Absolutely fabulous that from one plant 3 or 4 different shades of pink/lavender/periwinkle can be enjoyed.
How do we go about changing color? First, the change from pink to blue. These amendments can be added to the soil to increase acidity or lower the pH number:
- peat moss
- ammonium nitrate
- ammonium sulfate
- sulfur coated urea
- iron sulfate
Pink hydrangeas favor a high phosphorus content and a more alkaline soil with a higher pH, try adding:
- dolomitic lime
- kidney beans
- baking soda
- fertilizer such as 25/10/10
- ripe bananas
- planted by a concrete walkway or garden ornamentation (lime from concrete leeches into the soil)
- mix 1 tablespoon vinegar with 1 gallon of water
Hydrangea macrophyllas can be used as filler plants, foundation plants, hedges or for cutting flowers, especially weddings. They prefer morning sun only and like a good drink of water each week. So if you do not have an irrigation system, plant your hydrangea by the house in close proximity to a water source.
