Growing Hydrangeas

In general, hydrangeas can adapt to various atmospheric conditions, including both sunny and shady environments. They require adequate sunlight for blooming and some shade to protect them during hot, sunny days. However, excessive shade can delay or inhibit bloom production.

When it comes to planting hydrangeas in Colorado, finding the ideal well-draining soil can be a challenge. Fortunately, Colorado gardeners can improve their soil conditions by incorporating the compost, which helps retain moisture for the effective growth of these colourful shrubs. Mulching is also beneficial for moisture retention.

After planting, it is crucial to water the plants regularly for approximately two years or until they are well established. During winter, watering should be done infrequently to prevent winter damage.

Hydrangeas respond uniquely to soil chemistry. If the soil is acidic, they produce blue flowers, while alkaline soils yield showy pink blooms. If you wish to modify the soil pH to achieve desired colours, you can apply various soil treatments and amendments, such as using peat moss and mulching.
