Dust is another factor that adversely affects the growth of Philodendron plants by settling on the leaves. What happens is that the dust collected on the leaf forms a layer that prevents the leaves from performing photosynthesis properly and this greatly affects the growth of the plant. This results in smaller leaf growth.

Solutions

What needs to be done is that a microfiber cloth should be used to dust the plant about once a month, and it is best to keep the plant in a place where there is comparatively less pollution or less dust and dirt. This will remove the dirt or dust that has settled on the leaves and help the Philodendron plant to produce good energy more efficiently.

Improper watering

An important step that needs to be taken to ensure that the Philodendron plant has leaves of normal size is that it needs to be watered properly, on a daily basis and the Philodendron plant should not be overwatered or underwatered. This is very important.

However, watering your Philodendron plant is not as easy as it sounds, because how much you should water it, or how frequently you should water the plant depends on factors such as temperature, time of the year, and also humidity. Overwatering the plant also hampers the growth of plant.

On the other hand, if the soil feels wet to the touch of your finger, then the plant should not be watered for some days, that is until the soil dries up.

If you are not too sure about whether you should water the plant or not, you can also choose to use a moisture meter. The moisture meter is used to measure the moisture content of the soil.  The meter is stuck into the soil and if the reading shows dry, then you can go ahead and water the plant.

Lack of essential micronutrients

Various micronutrients are essential to the growth of Philodendron plants and for their leaves to be of normal size. The various micronutrients which are important are calcium, magnesium, and potassium. The lack of these micronutrients hampers the growth of the plant greatly.

Sometimes, continuous planting of trees also results in the nutrients of the soil being consumed, and then, when a new batch of Philodendron trees are planted, there are not enough essential micronutrients left for them.

Solutions

This can be solved by using various added products that will help restore the normal level of these micronutrients in the soil. There are various fertilizers, that can be added to the potting soil to improve the fertility status, and provide the necessary micronutrients to the plant.

Plant is pot-bound

This is a common problem in Philodendron plants when it comes to the size of leaves being smaller than normal. Very often Philodendron plants become pot-bound and this results in the growth being inhibited, their leaves becoming smaller and the plant looking less healthy and lush.

When roots of Philodendron plants take over the pot and begin to grow in circles, it slowly suffocates the plant. However, this can easily be solved by the following process.

Solutions

The only way of solving this problem is by repotting the plant carefully and by closely following all necessary instructions.

The plant must be lifted out of the pot and it must be observed whether it has any knotted roots or not. These entangled roots inhibit the growth of the plant and the plant now needs to be planted in a new pot that is preferably a few inches bigger than the last one. Well draining soil, that is loose and rich in organic material should be used for replanting.

Incorrect temperature

Philodendron plants prefer a temperature range of 60°F to 80° F. They can grow in temperatures as low as 55° F but that is not healthy for the plant and therefore not advised.
