Maintaining hydrangea plants can be a piece of cake, if you provide them with the suitable environment. Choose a spot where you can plant them in nice, well-drained soil and with a bit of sunlight - hydrangeas do best when they get morning sun and then a bit of shade in the afternoon. Make sure you give them enough water so that the soil stays humid without getting drenched, especially during the summer days. Besides watering, put a layer of mulch on the soil surface to not only keep it humid but also to protect the roots from extreme hot or cold temperatures. Generally, the pruning is done after flowering however it depends on the type of the plant. Applying a balanced one during the growing season is necessary for vigorous flowering. A flower's color depends on soil pH indeed you can shift the hues by changing it. Lastly, to keep them flourishing, shield the plants from intense sunlight and strong winds.
