Water Quality Can Affect a Pothos

In general, Pothos plants dont care about how their water is treated. Because Pothos is a type of houseplant that can withstand some heft and a bit of stress, it is the perfect plant for novice or busy gardener.

The watering of your Pothos using tap water will be fine. If youve tried some of the alternatives and it does not blend the browning of leaves, you might want to look at the quality of the water you use.

A water that is filtered to room temperature is ideal since it doesnt alter temperatures of the Pothos excessively.

Lack Of Humidity can Affect Pothos

We will now examine the ways in which humidity affects the pothos plant. It is crucial to test the humidity of the place where youve placed your Pothos.

While Pothos is able to thrive in low-humidity environments however, they prefer areas that have higher humidity because theyre native to more humid climates.

Humidity levels are usually one of the environmental variables that gardeners who live in indoor environments often overlook when they are taking care of their plants. Your Pothos will flourish and grow to the fullest extent when you supply them with the humidity levels that are closest to the natural conditions they live in.

Uncontrolled humidity can affect the levels of transpiration in your Pothos. The water that is loaded with nutrients is absorbed by root systems of Pothos and any extra water escapes through the tiny pores.

The tiny pores on the pothos plant are known as Stomata. It is found on the lower part of the leaves once your plant has taken in the nutrients.

In the event that your Pothos is in an area with low humidity, itll be in a state of shock and will not fully let its pores open. In the end, transpiration will decrease, and the general condition of the Pothos will begin to decline.

Since a pothos is a fairly robust plant, it is unlikely to exhibit any signs immediately of health issues worsening however, its overall performance and growth will slow down. It is at this point that youll be able to see the edges of the leaves becoming brown, which indicates the air is dry.

Humidity refers to the amount of humidity that the air in a particular region can store. The more extreme the temperature is higher, the more moisture is within the atmosphere. However, its not always that simple, since even in a climate that is dry and hot, the humidity could remain low.

This is especially true in desert areas. This is due to the fact that there need to be a mix of warmth and moisture to create humidity. In the event that youve got a heating system inside your house and there is no moisturein the air, it is going to dry out and humidity levels will decrease.

If there is moisture in the vicinity but the warmer air will be able absorb it, and levels of humidity will increase. It is essential to do your best to keep the levels of moisture that best suit your Pothos most.

It may sound a bit complex, but if you make sure you have the right humidity levels, youll find the Pothos as a much healthier and attractive Plant!
