Question

Yellow leaves on my gardenias I live on the Gold Coast in Queensland Australia?

Answer 1

This is an old fashion remedy but it works and quite quickly ,epsom salts disolved in water and then sprinled over plant ,

Answer 2

I'm on the goldcoast to and my gardenia also has a few yellow leaves. I'm sure that has happened before and they just fall off and more grow but mine is due for a bit of a prune so I will do that and throw a bit of feed around

Answer 3

I have found that yellow leaves on my plants usually means they are lacking in some important nutrient.  Since I do not Know your soil type there it would be most helpful for you to see your local nursery-man, perhaps if you were to take a leaf from your plant and a small soil sample, he would be able to be more precise.

Answer 4

Yellow leaves on a gardenia means the plant is in need of magnesium. My mother used to dissolve Epsom Salts (hydrated magnesium sulfate) in water in a watering can and pour on her gardenias. It works too.

Problem - Gardenia leaves are turning yellow.

Solution - Place some magnesium-rich fetitliser close to its roots. Within a couple of weeks the leaves should start to turn green (instead of sickly yellow). The plant should also begin flowering.
