Hydrangeas, or Christmas roses, as they are affectionately referred to, are not only easy to grow, but are also quite hardy and resistant to most pests and diseases. Most hydrangeas fare best when planted in dappled or partial shade. They will grow well under trees and along the west side of your home, where they are protected from the midday sun. Water is an important factor when you care for hydrangeas. They enjoy deep watering at least once a week, especially in dry weather. Hydrangeas also benefit from an occasional boost of fertilizer once or twice a year.
The pH levels of the soil determines the colour of the hydrangea flowers. An acidic soil with a pH of less than 5.5 will produce hydrangea plants with blue flowers, while soils that are alkaline soil and have a pH of higher than 5.5 will produce hydrangeas with pink blooms.
An easy way to manage the pH levels of your soil and obtain the colour of hydrangea you are wanting is to simply plant them out into pots. It’s far easier to manage the pH level of soil in a pot than in a large garden bed.
