Q.Kaffir Lime Turned Yellow
We live in north-central Victoria. We have a potted kaffir lime tree which we bought nearly 2 years ago. It has been growing well but recently all the leaves and fruit have turned a light green/yellow color, which doesn’t make it look very healthy. We have it outside. Could it be because of the cold? I have given it liquid fertilizer and it hasn’t helped. Can you please tell us what to do to make it look healthy and green again?

Yellow leaves are more often than not a sign of overwatering. Feel the soil around your plant to see if it is too wet. If so, stop watering. Plant stress can be another factor, such as a sudden change in temperature. Since it is outside and you stated it was cold, this could definitely be affecting the tree, as they do not like cold conditions. You may want to consider bringing it indoors if the weather gets too cold.
