Calcium or lime to raise ph?

keepingon

I am preparing a spot to plant HF Young. De Groot nursery said add calcium to acid soils at planting to raise ph to 5.6-6 range. I have always used lime to raise ph (for hydrangas) and have it on hand. I know it takes several months for lime to work. There is very acid soil (5-5.5) in some areas of my Alabama garden.

Can someone offer advice on which product might be best. Does one work faster, last longer, etc; or if there is any advantage in using calcium over lime. I would like to use what I have and will be soil testing as I correct ph. Thanks, Mike
