Overwatering, the main cause of yellow leaves on plants

When all the leaves of the plant or a large number of them turn an intense yellow color on a regular basis , it is very likely that we have overwatered the plant or that the substrate or soil does not offer adequate drainage. If you touch the soil and it notes wet and caked, you need to aerate the soil by stirring it and applying sandy-textured soil to the mix.

Lack of watering, cause of plants with yellow and drooping leaves

If the leaves turn yellow into a wrinkled texture and the entire plant seems to be decaying and losing strength, it will most likely need more water. When one of your plants has suffered a severe drought, don’t overwater it. Instead, soak the entire planter in water for a few minutes, then let the soil drain off the excess.

Plant with yellow leaves due to poor soil

Plants need minerals and nutrients like nitrogen, phosphorus, and potassium . When the nutrients in the pot are depleted, the plant will start to yellow. If this happens, you should either transplant it or apply compost to the soil. Discover How to make homemade organic compost for plants in this other article.

Yellow leaves on plants due to excess or lack of light

Some plants are not prepared to withstand direct exposure to the sun’s rays, especially in climates where it shines very brightly. If you see that some leaves that should be dark green begin to yellow, move your plant to a location with more shade or where it is protected from at least the worst hours of sun.

It can also happen that the plant is not receiving enough light and is unable to photosynthesize. This case can be differentiated from the previous one in that here the leaves will take on a whiter than yellow color . When this happens, move your plants to a brighter area or, if you can’t, consider purchasing a plant lamp. In case you observe white spots on the leaves of the plants , do not hesitate to review the causes and possible solutions.

Inadequate pH and yellow leaves

Many plants need a soil with a certain level of acidity. When this is not met, the plant will not be able to absorb the iron it needs from the soil and will begin to yellow. It is possible to get strips or sets to measure the pH of the soil and thus be able to assess what substances or materials you need to add to increase or reduce it according to the specific needs of the plant.

Cold weather, causing yellow spots on plant leaves

Some plants can experience cold spells by showing yellow spots on their leaves, even when in climates suitable for their species. The usual thing is that it occurs, above all, in plants that are not used to these conditions because they have been raised in greenhouses or more sheltered areas. If this happens but the climatic conditions remain at those recommended for the plant, don’t worry, when the warm months arrive it will recover.

Leaf tips yellow and dry from drafts

There are indoor plants that should not be in locations exposed to drafts on a regular basis. If this is the case, you will see that the tips of its leaves dry or yellow and the plant could lose them. So, if you have observed yellow leaves on indoor plants, simply change their location to a more sheltered one.

Yellow leaves on plants by the arrival of autumn

If the plant is not evergreen, with the arrival of autumn its leaves will turn yellow or brown and finally end up falling. Obviously, it is a natural process that does not indicate that anything is wrong.
