Winter is sneaking up.

Even inside a greenhouse, winter is approaching. It is time to adjust watering and fertilizer. It is time to find the "dry winter rest" plants.

I have learned that reduced hours of light is a more important factor than temperature. And by 'learned', I mean the hard way. Killing plants by over watering.

I will take down some of the shade cloth and more at the end of the month. I will reduce the watering to every other day now. I will move the plants off of the bench near the door, take in outside and clean the greenhouse floor.

But there are going to be days where the temperature doesn't get to 60 all day. These are days when a wet plant will start to lose roots.

I also have a number of Pleurothallidinae in the collection. These rely on the foggers for most of their watering. The foggers have stopped coming on very much because the greenhouse is in very little need of cooling. These need to be inspected, repotted and gathered to where they can be hand watered.
