My guava tree has started loosing leaves and few baby guavas still havnt droped. Winter is about to start and day temp is aroud 25c. But as much i know when winter is about to start or during winter tropical plant turns their leaves yellow and then drops the leaves. But mine is dropping green leaves and few leaves turned brown and some portion and then dropped. And my plant is almost 1.5yrs old. Can anyone help me please if my plant is safe or not.
