Checking if a pothos stem is splitting

The Main Factors that Cause Pothos Stems to Split

The main factor that causes pothos stems to split is low humidity. In fact, when you grow your pothos in a low-humidity area, they are susceptible to splitting because such an environment is different than the one where pothos originate.

Direct sunlight exposure is also a common cause behind the splitting of pothos stems. Generally, pothos needs light to grow, but they should only be exposed to indirect sunlight. When pothos get exposed to direct sunlight, they are likely to grow leggy, and the stems are more susceptible to splitting.

Overcaring may also cause your pothos stems to split, especially overwatering. In fact, overwatering can lead to root rot which is another cause of stem splitting.

Severe environmental conditions such as high temperature may also lead to stem splitting: in particular, pothos doesn’t do well when the temperature goes above 85 degrees Fahrenheit.

Sometimes the split of your pothos stems may be due to physical damage caused by a pet or a human. For example, if a cat starches the leaves of your pothos, the branches are very likely to split because of damaged tissue.

Last but not least, another common factor behind stem splitting is using the wrong type of potting mix. Make sure to use a light and fast-draining potting mix for your pothos plants to avoid this problem.

What Should I Do if My Pothos Stems Start Splitting?

If you realize that the stems of your pothos are splitting, you should automatically think of humidity. One way to check the moisture of your pothos is to take a piece of tissue paper and place it on top of the soil. After a few hours, if you notice any condensation or water on the tissue paper, the humidity is high.

If you detect a low humidity level, you should use a humidifier to increase the humidity level. If you don’t have a humidifier, try putting your plant on pebbles and watering it from the bottom.

Try to water your pothos systematically; you should not water your plant until you have a clear indicator that it needs to be moisturized. The best way to know whether your pothos needs water is by checking if the soil has started to dry. You can water the plant if the soil feels dry to the touch.

When watering your pothos, make sure that you are using clean water. But, even when you use clean water, you should avoid overwatering because this is another common cause behind stem splitting.

Also, keep the temperature around your pothos at an optimum level. The best temperature that helps pothos thrive is between 70 and 80 degrees Fahrenheit. To maintain the temperature of your pothos in that interval, you can use a thermostat or an air conditioner.

When you realize that your pothos stems start splitting, you should check if there are any bacteria or fungi around your plant. Infestation is also a common cause behind pothos stem splitting. So if you see any infestation on your plant, you should immediately treat it with a fungicide or any pesticide you trust.

Getting big leaves on your pothos is not a difficult task. It would help if you started doing things right from the first days of growing your pothos.

If you wish for your pothos to grow at their full potential, you should use an appropriate fertilizer and a rooting hormone.

If you do so, you will find that your pothos starts increasing faster. And if you are developing a pothos variety with large leaves, you will get more giant leaves in less time.
Pruning your plant regularly can also stimulate your pothos leaves to grow bigger. In fact, after pruning, a plant’s energy will be redirected toward developing new leaves, making the plant look bushy. This helps the plant to get more light, which results in more giant leaves.
