Cold-weather laelia flower spikes dying
I have two cold-weather Laelia albida x gouldiana, each of which put out two flower spikes in April. All four spikes turned brown in early May and are pretty obviously deceased - lengths range from 75 to 200 mm. Any idea why this might have happened? The plants otherwise look very happy. The psbs are fat and smooth and two other laelias (different hybrids) receiving identical cultural attention have several excellent spikes each.
All plants are grown on a south-facing verandah with a clear, polycarbonate roof. Temperatures in April-May are 7°C to 20°C.
Note that I'm in Australia where the equator is to the north and summer is in December. A couple of photos are attached.
This is my first post on this forum.
