Dendrobium Frosty Dawn 'Wings of Gold' (NOT!)

[catwalker808]

Calvin. The photo I posted is 'Wings of Gold' ... same clone as what you have. Did you read my post above?

Yes. The plants do need very good drainage and lots of water during the growth season. But I cannot emphasize the need for good drainage. If you have the drainage, don't be afraid of watering because, when they are in new growth, that's the only time significant new roots are developing. But better to underwater than to have wet and soggy feet. That will rot the roots. Prolonged underwatering may cause water stress, yellowing and some leaf loss. In nature, all of the involved species grow attached to trees ... in effect, they are "mounted", since there are few potted plants in nature.

Frosty Dawn has a mix of formosum dens in the background. Frosty Dawn = Dawn Maree x Lime Frost. Dawn Maree = formosum (warm, large, robust plant, 3-1/2" spring white flowers, yellow lip, only at tops of canes) x cruentum (warm, slender, few canes, random season, light greenish/cream flowers, brilliant red in lip). Lime Frost = scabrilingue (warm-intermediate, small fragrant spring whites, yellow to light orange lips, semi-deciduous) x cruentum. Cruentum background allows Frosty Dawn to often bloom spring and fall. Scabrilingue lightens lip from Dawn Maree red-orange to Frosty Dawn orange. Scabrilingue also gives nice fragrance, but its semi-deciduous habit also causes some lower leaf drop in Frosty Dawn during cold winter periods, or when plants experience major climate change (sudden chilling). Partial leaf drop is not harmful and is a normal reaction when it is very cold.

Thanks for the tips - Yeah I was referring to your other thread.

I have it potted in a very loose mix with tons of air - I found that they like that too. I'll make sure they get more regular water though - I started doign that and so far the yellowing has stopped
