There are two main types of Dends in general cultivation the first and more popular type is evergreen, the so called 'phal type dends'. The second type is deciduous and will (should) lose leaves and go dormant in winter. ArthurM can and may post here and tell you what type a Kiwi Love is, I myself do not know. What I can tell you is that if you don't know then likely you have been watering it regularly till the present time. Even deciduous type dends depend on external cues for their leaf drop and water is one of them. In true indoor conditions where seasonal cues are extremely blunted it is hard to get many deciduous plants to 'go down'. It is interesting that yours is doing so. Dends are real light lovers. I wonder if screened East light is really doing it for that orchid. You might want to look into that going forward.

The correct name of the orchid is Dendrobium Kiwi's Love and it is a typical warm growing Phal.type/Hard cane Dendrobium.

It is normal for some of the leaves to go yellow and fall off but only on the oldest cane/pseudobulb.

Just looking at my plant of Den. phalaenopsis (the species) the first four Pseudobulbs are fully leafed and only the oldest are leafless.

As for the screened porch, no idea if the will give adequate light. At this time of year mine is getting a few hours of full sun through clear glass then sun filtered by the hail-guard shade-cloth covering the roof of a glasshouse for the rest of the day.

Howard & Arthur, thanks for the response. My thought was that my Den. Kiwi's Love was getting too much sunlight. Based on your feedback, I don't think so. It is just the oldest cane that has yellowing leaves. Could be this is normal. I will watch closely and let you know. Thanks again.
