Red Aglaonemas need help!
I bought four red Aglaonemas from Thailand in last December. Since then the plants are getting weaker and weaker. In the beginning they'd six leaves each, but now left only three leaves. What is the cause? I've few others green cultivars e.g. King of Siam, Green Sun & etc. They seem have no problem in the same condition. All of them are in my living room with day temperature 20ÃÂ°C and night 18ÃÂ°C. I water the red ones once in two weeks. Those green ones are in Lechuza pots. Thanks for the answer.
