Rotating Houseplants Is Important but Often Overlooked
What Happens If a Plant Does Not Get Rotated?
Rotation should be a regular maintenance procedure for any interior plant; however, you can often see signs that this basic upkeep has been overlooked.
You may have seen:
- A tree or cane type plant that casually leans to one side in the middle of a hallway.
- A ficus that is leaf-bare on one side with uncontrolled growth on the other.
- A plant that clearly demonstrates the reaching effect as the plant has grown toward light.
Understanding the importance of regular rotation is vital for maintaining healthy happy houseplants.
Consequences of Unturned Plants
Why Rotate Houseplants?
In most interior spaces, light sources are not available evenly overhead like the vast blue sky outside. More likely, a window provides light—in some cases it may be a skylight or some sort of beneficial overhead lighting source. For example a fluorescent light does not move across the ceiling as the day goes on, and a window does not move around the room.
Plants always grow toward light, and since our interior light sources are fixed, houseplants will begin to grow in a very targeted fashion toward the light. If a light source is off to one side (which it usually is), rotation will signal to the plant that the light source is in a different place. If the light is periodically present at different places all around the plant, it will signal productivity and growth all around, producing balanced foliage production. Trees and cane-type plants will be less likely to lean to one side or another, desperately reaching for light.
If a plant is left to its own devices, it can begin to tilt or grow very off-balance toward the light. In order to prevent this from happening and keep your plant looking great for the long term, regular rotation is recommended. These rotations will produce growth and productivity where foliage is exposed to the light.
Basically, the reason we rotate plants is to distribute light evenly around the entire plant body. When a plant is outdoors the light moves, but indoors, we must simulate this effect by moving the plant.
The objective is to achieve an aesthetic symmetry.
How & When to Rotate
How and when a plant should be rotated depends on the kind of plant it is and the lighting situation.
- If you have a fast growing plant like a ficus in front of a good, natural light source like a window, the rotations could be periodic and dramatic. In such a situation, some light would be reaching the whole plant but would not be evenly distributed. In this case a 180 degree turn would be fine about every two months, allowing each side to even out and preventing the plant from growing into the window. Regular pruning would also be recommended in such a situation.
- With a plant like a philodendron that enjoys moderate light and is in a moderate light condition with exposure on only one side, rotation should be frequent. Such a scenario would create a plant that would reach toward the light on one side and would defoliate on the side that remains in relative darkness. To maintain balance, this plant should have regular 90 degree rotations about once a month to maintain foliar balance.
- For plants in lower light conditions, either slow or fast growers, the rotations should be very frequent and incremental. A weekly or bi-weekly 45 degree turn would be best to prevent or reduce uneven defoliating and discoloration.
Light Makes Plants Move
Rotating your houseplant will allow you to enjoy a well-rounded, symmetrical, healthy plant for a very long time. It will keep you plant well-suited to the space in which it has been placed, and it will simply look better.
Know that as you rotate your plant, it may look a little asymmetrical for a short period of time, but this should correct itself within a couple days after the plant senses the light source.
Don't forget this very important aspect of maintaining a healthy indoor plant.
