Indoor plants can make any space more inviting and comfortable adding touches of color and subtle fragrance to your home. Unfortunately, sometimes your houseplants don’t grow as straight as you expect them to. The fact that there are several causes for indoor plant leaning also makes it tricky to discover why this is happening. To help you solve this problem, we’ve listed the most common reasons why plants lean and the solutions to remedy them.
Not Enough Light
Indoor plants need the same amount of light that they would get if you planted them outside. The issue is that some rooms in your home may not provide your plants with adequate sunlight. In fact, poor lighting is the most common reason for your plants to start leaning, so this is a good place to start investigating. This is because a plant will try to reach the sunlight that it’s missing and do what it can to get more of it.
If the light is too high, this could cause the plant to become leggy and spindly. This can be the cause by improperly placed grow light, or with natural light if your plant is not getting enough. The plant naturally does what it can to try and get closer to the source of light and hopefully receive more of it. Those thin stems can’t support the plant, so they start to lean.
Another issue is that only one side of the plant is getting the light it needs. Outside, the sun moves across the sky providing more equal illumination, but when it shines in your window, it won’t reach all areas of the plant. When this happens, the plant will lean towards the light, growing in this direction instead of straight up. You may also notice the yellowed leaves on the lighted side and falling leaves on the side without sun.
To solve the inadequate lighting issue, first, place your plant near a window that is giving it the light it needs for the recommended amount of time. Though some plants like minimal light, others require hours of bright light to survive, so a south-facing window will provide a location that receives the maximum amount of light. You can move the plant closer to the window if needed to increase the amount and intensity of light it receives. Future leaning can also be prevented by rotating your plant each time you water it to ensure all sides are getting the right amount of light.
Lastly, consider getting a grow light if you’re frequently having trouble with leggy and leaning growth. Grow lights can help supplement for lack of natural light, and therefore solve many of the above problems.
Plants need specific amounts of water to thrive, so if you’re giving them too much or too little it can cause them to deteriorate and start to lean. Of course, there are different reasons for this depending on how much water you’re adding to the soil.
If the plant isn’t getting enough moisture, it can become dehydrated, which weakens the stems until they can’t support themselves, causing leaning. Too much water is also an issue since the roots can’t absorb it all, soaking in the moisture instead. This causes the roots to drown and rot, making it impossible for them to supply the plant with the moisture and nutrients it needs to survive. At this point, the plant can begin to lean.
If you think your plant is being overwatered, there are ways to determine this. First, insert your finger an inch or so into the soil. If the soil is dry beneath the surface, then your plant isn’t getting enough water. Add enough to soak it until water is leaking out of the drainage holes. Then test the soil again every few days to be sure it is still moist.
If too much water is the issue, let the soil dry out completely before adding any more. Place the plant in bright indirect sunlight to help dry it out faster. Only then should you add small amounts of moisture until the plant starts looking healthy again. Be sure to test the soil as described above to see if more water is needed.
The Plant is Root-bound
When a plant is grown in a garden or yard, its roots have the room needed to spread out as they see fit. Indoor plants don’t have this luxury, and this means that it’s possible for them to outgrow their containers. If the roots don’t have enough room to spread out they won’t be able to provide the necessary water and nutrients to the rest of the plant, causing it to droop and lean.
The roots can also become tangled and this will also prevent them from absorbing nutrients and moisture. This is what is referred to as root bound, and can lead to serious problems for your plant.
The best way to fix a root-bound plant is to first check the drainage holes. If you see the roots poking out, it’s time for a larger pot to give those roots room to spread out. The best time for this is during the plant’s growing season between spring and fall when the plant is full of energy and the roots can sprout new shoots.
