Plants Do Not Grow in the Dark
You can have house plants in the dark, but you cannot just leave them there, they will die. This is because plants do not grow in the dark, sunlight is necessary for plant growth, even if it is reflected light.
Keeping house plants in the dark will only weaken them and they will become soft. Just because a plant is called an indoor plant, does not mean that it is going to survive in all places in the home. There are many indoor plants that actually require quite a lot of light, too.
To define low-light, if you can still cast a shadow, or still read a book by the available natural light, then it is low-light. Anything with less light is, well, dark. If it is necessary to use artificial light to enter a room, then it is too dark to grow plants in.
Some of the areas defined as low light, might be the far end of the hallway, some downstairs room, bathroom, etc. Apartments are often lacking window space, or may have little windows.
If you are determined that you simply must have living plants in the really dark areas of your home, there is a way, but it requires effort. This idea requires that you set up a system of rotation with your house plants.
Rotating Your House Plants in the Dark.
This will only work if you already have house plants growing in more favorably lit areas.
Before we start, you can Only leave indoor plants in darkened areas for a few days, three to five – at the most. You replace this plant with one of your other houseplants, that is currently getting the most light.
Move all your other plants one spot closer to the brightest area. The plant you took from the dark area, is placed in the least lighted area. If all plants get the same amount of light, all good and well, just swap out one plant at a time – light for dark.
If you take the plant from the dark and stick it straight outside in the sun, the leaves are going to burn and, the shock will probably kill it. You must introduce it to the sunlight again, gradually.
Along the same lines, If the plant has not regained its full health by the time you have run out of other plants to replace it with – get some more. If you put an already weakened plant back into some dark recess, it will only continue to weaken.
This is a fair amount of effort just to have some plant down the end of the hall. Therefore, it may pay to first assess just why you want it there in the first place. Does that area get a lot of passing traffic? Could be simpler to merely buy any of the life-like silk-plants commonly available.
