I am growing them since last 2 years and one thing which I fail to understand is no new leaves appear on them from November to January time,I tried everything but no result,I have planted same plant near the seashore just 30 kms away from my place and I am surprised to see it is blooming like anything though soil there is not as good as what we have,does this have anything to do with the dry climate at my place during winter?btw I am in India.Any feedback shall be highly appreciated thanks.
