Rx Please Sago Doctors
Advice on this forum accounts for most of what I know about cycads--thanks for your contributions.
As you can see from photo album link below, some of my sagos did not winter well indoors. Live in Tennessee; take in Thanksgiving, out early March. Stored in upstairs room that's heated, fairly bright (dormers and skylights) and 40% humidity via humidifier. Before taking indoors, spray with Neem.
Lowest fronds on two large sagos (pix 1-4) typically turn brown indoors. But this winter they have more extensive browning and a brown scale (see detail, pix 5). Some of the other sagos in same space (pix 6,7,8) came through fine with much less scale.
What did I do wrong please? And how should I treat now? Advice much appreciated in advance.
