If your plants have yellow leaves, you may be making several mistakes. But don’t worry, because even those with a green thumb often do them by mistake.

In this article, we are going to look at the various reasons why houseplant leaves turn yellow.

Plants with yellowed leaves

The appearance of the leaves reveals the health of the plant itself. The presence of yellow leaves on the plant is normal if they are found at the bottom of the plant, since they are old leaves that are giving way to new ones. But  if all the leaves turn yellow at the same time,   then  there is  a problem.

Yellowing leaves can have different meanings depending on the type of plant. Yellowing of leaves can be caused by:

• excessive or insufficient watering,
• lack of minerals;
• thermal stress.

If the plant has aged and dry leaves that curl inward, it is most likely that  they have not been watered enough  , especially if we notice that the soil is also very dry.  The solution to this problem is simple: just water the plant. 

If yellowed leaves tend to turn green, it often means that the soil is too wet and can also attract fungus gnats, which can lead to plant death. In the case of blackened stems it means that  the plant is receiving more water than normal  .

At this point there are  two solutions:  the first is   to repot the plant to remove  the soil that is too wet, the second is to let the soil dry out on its own. Of course, let’s remember in the future not to overdo it with water.

deformed leaves

Yellowing of deformed leaves is usually  caused by the presence of a parasite or a deficiency of minerals  , such as calcium and boron. The solution to this problem is   to fertilize the plant once a month  or repot it to provide new nutrients to the cooler soil.

When the entire plant  is yellow and the leaves are about to fall

In this case the problem comes from the  temperature.  The plant in question is probably in a position where it is too cold or too hot. The leaves take on a paler, almost whitish color.

It could also be a  fertilizer problem  . Therefore, the solution  is to move the plant  to a more suitable location or try a new fertilizer.

Semi-yellowish plant

If the plant is taking on a dull color, it may be a problem with the roots.  The pot may be too small and the roots do not have room to expand  . So   the solution is to transplant it to a larger pot.
