Curry leaf plant leaves are reddish

I often hear concerns about the newly shooting leaves are reddish and the plant might die, or if the reddish leaves are not the problem.

This phenomena is caused by the plant generating anthocyanins to protect chloroplast in the newly shooting parts of the plant get damage from UV. You might have seen some cabbages or broccolis have purplish part, and that is the same phenomena.

Therefore, you do not have to worry about the reddish leaves to affect growth of the plant. It will disappear when the temperature rises and the plant continue to grow.
