I have a Calamondin tree which I bought for Chinese New Year. When I brought it home, it started to drop fruits and lose leaves so I decided to put it outside. I should tell you that I live in KL and the AC is on in our apartment most of the day. The outside temperature is hot and humid. Since transferring the plant outside, it seems to have died, even though I have watered it regularly and it is not in direct sunlight all day. Can I save this plant?
A couple different things may possibly be happening here. This plant is recommended for plant hardiness zones: 4-11. Malaysia is zone 14. So, a calamondin tree is not very ideal for your area which may explain why it has not been doing well since placed outside.
I am wondering if maybe the tree has been overwatered - citrus will falter in waterlogged soil. Is your soil damp/soggy or dry to the touch? Water only when the surface inch of soil has become dry.
I would also inspect your tree for mite and scale infestations, as they can affect the health of a citrus tree.
Also, have you fertilized your tree at all? If not, I would recommend that you do so.
