Why are the leaves on my hibiscus tree turning yellow?

Question

They turn yellow and fall off – am I over watering or underwatering?

This article should help pinpoint the reason for your yellowing leaves: https://www.gardeningknowhow.com/ornamental/flowers/hibiscus/answers-to-what-causes-hibiscus-leaves-turning-yellow.htm

Answer 2

Is most certainly over watering. I have just bought a lovely apricot colour one and was told by the nursery that they don't like too much water as they are from New Zealand and that the leaves would turn yellow and droop if too much water. Hope this helps
