Hydrangeas are a wonderful, old fashioned bush that deliver explosive color. They look absolutely amazing clumped together …
Most hydrangeas thrive in rich, porous, somewhat moist soils. It is advised that you add compost to enrich poor soil. Hydrangeas thrive in full morning sun and they like afternoon shade.
They will still grow and bloom in partial shade. The photo below was found on Bella Wedding Flowers and it’s a great example of the typical hydrangea colors. There are so many choices!
Did you know that by changing your soil pH, you can change the colour of Hydrangeas? There are some limitations to this process, so the following needs to be taken into consideration. You can not change the colour of White Hydrangeas to pink or blue.
As the Hydrangeas age, sometimes a bit of red comes through the blooms. This is purely down to nature. Whilst you may see pictures around the web of blood red Hydrangeas, a dark pink is a more realistic result, particularly if you live in a hot climate.

If you are a keen gardener, you will know just how important PH Level is if you want your garden to not only survive but thrive. This is what Garden.com has to say:
“The pH scale has 14 units and is centered on 7, which is neutral. Levels below 7 are considered in the acidic or sour range; readings above 7 are alkaline or sweet. Soil nutrients are at their optimum availability in the range between 6 and 7.
Most plants grow best in this range, although some type of plant growth can take place anywhere between 3.5 and 10.” The soil is of particular significance to hydrangeas as acidity determines color.
If the soil is acidic with a pH of around 4.5 to 5.0, the flowers will be light blue to electric or even peacock blue as is often the case in mountainous conditions. However, most garden soils are much less acidic and the flowers pink.
The white cultivars remain white regardless of the soil pH but if you want to change the color of the other cultivars, lime the soil for pink flowers or add aluminum sulfate for blue flowers. You must change the soil pH before flower buds form if you want to change their color so treat the soil after August.
Hydrangeas tend to get sunburnt when in full sun as indicated by a browning of the flowers and or foliage.
They hate north winds but thrive in dappled shade or on the south side of the house. Hydrangeas don’t like to dry out too much and will wilt when they need watering.
A bucket of water a week should be enough to keep them going in warm weather. Feed them in June with complete fertilizer. They have fibrous roots close to the soil surface so mulch is recommended. Overall, hydrangeas are really tough and will survive almost anywhere, even in a windy coastal spot. To find out how to complete your PH Soil Test visit Texas Garden Girl
