Last fall, I brought my vanilla orchid inside after its summer vacation on the back patio. It was alive, and had grown quite a bit, but it hadn’t topped out the trellis….Now, as I look at the thermometer and begin to count down the days until it, and all my “house plants” can go outside, the vanilla vine is still alive, but still not huge.
The trellis I built is basically a quilt made out of hardware cloth, wire fencing with smaller holes than chicken wire. The middle layer of the “quilt” is sheet moss. I rolled the quilt into a cylinder about 4 inches in diameter and 2 feet tall. I filled it with orchid mix, then set up a pop bottle with pinholes in the bottom. It is both a tower for the vine to climb on, and an evaporator. It is also modular- I can build another cylinder that will fit into the top, if and when this little vine decides to grow up to the top of this one.
If you are wondering about how much support you need for your vanilla plant for the first year or two, the answer is, a chopstick would have worked for this guy. It doesn’t need a two foot tall tower. However, the other design element was for a humidity source for the plant- it is dry here, inside and out, on the front range of Colorado, and the trellis also acts as a humidity tower. It spends the winter in The Boy’s room, which also has a fish tank, and a new anole habitat-( and the cricket habitat that goes with the lizard- I didn’t realize that when I said yes to the lizard, I was saying yes to crickets, as well) The fish tank evaporates quite a bit, as well as the anole habitat, but it is still a centrally-heated room in a house in a semi-desert.
When I first built the trellis, the vine was only 4 inches tall- now, roughly two years later it is about 12 inches tall. If I were starting again, I might just use a chopstick, or piece of bamboo, and maybe use a hurricane lamp as a terrarium.
