Where I live the climate can be quite harsh. In the summer the temperature can reach 115 degrees and in the winter the temperature can drop to 20-30 degrees. I was planning on planting hygrangeas in the garden near my kitchen, however I have the option to plant them in full sun or partial sun. What would you suggest? I've never grown hydrangeas before, but they're my favorite so I want to make sure they'll do well.
Thanks for your help.

Hydrangeas will grow in full sun to partial shade, in rich soil, high in organic matter, that never dries out but also has good drainage. To achieve that beautiful blue color, your soil has to be on the acidic side (acidic soil produces blue hydrangea blooms, alkaline soil produces pink blooms, if the soil is very, very acidic, they will be white). To find out your soil's acidity level, you would need to have a soil test performed. Contact your local county extension office for details. Your soil report would also have advice on how to make any needed amendments to the soil.
