Yellowing Leaves Hi there,
I have a small section in a rented house and therefore have a lot of plants in pots. One of these is a recently obtained Gardenia. I know these like acid soils and it is just showing signs of not being too happy (yellowing leaves). I thought this may be due to the soil not being acid enough. Is there any way to organically acidify the soil.

Are the old leaves more affected? If so it could also point to a nitrogen deficiency. Without knowing the actual pH of the soil it is hard to recommend an action. However, applying a 50:50 mix of peat and well rotted compost should bring some relief (working it gently into the soil around each plant (a few handfuls per plant).
