I bought this unique plant at a small plant store in Ottawa last October.
I was told that it’s a succulent that crawls and requires water.
Although it looked healthy and growing well until December. In new year, it seemed to be wilting even though I kept watering. Then I finally gave up…
It had been placed at the corner of the room but close to the patio door that was faced to south-east.
It is difficult to identify the specific type of succulent from your photo. You may want to review our plant identification tips and resources located here.
Succulents require at least 4 hours of direct sunlight per day. You mention that your plant was in a corner, although near a patio window with southeast exposure. It is possible your plant was not getting enough direct sunlight, especially in the winter months when the days are short, and the sun is low in the horizon. In the future, you may want to find a spot with more direct light, or supplement with artificial light.
It is also possible that you overwatered your plant. Succulents should only be watered when the soil is completely dry, and watering should be reduced during the winter months — just frequently enough keep the leaves from withering. When watering, soak the soil thoroughly and allow the excess water to drain out.
