Important Gardenia question
This is my first post in this forum but I need to ask an important question.
I recently purchased a Gardenia Kleim's Hardy plant. Someone suggested adding shards of aluminum foil to the base of the planting hole in the container that it will be growing in. He said that it aids the acidic maintenance of the soil.
My question is, will this damage the plant in any way? The foil is covered in a 2" layer of compost (separating it from the rootball) but now I am a little concerned that it will adversely affect the plant.
PS I've also done this to my container grown Japanese Azalea shrub.
