Soil Acidity
 

Hello

We have a row of Gardenia's growing alongside a wall. I think that the lime
from the mortar and render is leaching into the soil and making it alkaline.
I was wondering what I should use to increase the acidity in the soil.

Firstly, you should have the soil tested before you start messing and
guessing. If your soil is alkaline, put coffee grounds around your
plants.... or purchase sulphur, but you will need to know how much
correction is necessary to change your soil.

Elemental sulphur, iron sulphate, peat moss are three possibilities

My camelias had the same problem. I used cow manure to fertilise them, a
layer 2cm over the surface and it happens to be acidic. I then follow up
with a pine needle mulch around 10 - 15cm thick over the top which gets
renewed every year. Works a treat!
