What to Do When Podocarpus Leaves Turn Yellow? Master Watering Methods and Frequency

There may be many reasons that cause podocarpus leaves to turn yellow, most of which are caused by improper cultivation, such as lack of water, insufficient fertilizer, inadequate light, and so on. So when facing some symptoms of podocarpus, we need to calmly think about why such a phenomenon occurs, and we can compare it with the correct cultivation methods so as to choose targeted solutions.

What to Do When Podocarpus Leaves Turn Yellow

1. Long-term lack of water in podocarpus

The specific manifestations are that the leaf tips or edges of podocarpus become withered and dry, while the old leaves turn yellow and drop from the bottom up.

Solution: Water in time and keep the soil moist, but avoid waterlogging. It is best to water thoroughly when the surface soil is slightly dry.

2. Insufficient light for podocarpus

If light is lacking for a long time, the leaves will turn yellow-white, and the branches will be slender and thin, making it difficult to bloom.

Solution: After gently rinsing the leaves clean, try to place the plant in a range from indirect light to relatively good light.

3. Too high temperature causing podocarpus leaves to turn yellow

When the temperature exceeds 35°C, the leaf surface or leaf tips of podocarpus will turn yellow, dry up, or develop spots.

Solution: Move the podocarpus to a cool place for care and avoid direct strong light.

4. Low temperature causing podocarpus leaves to turn yellow

When the temperature is about 10°C, podocarpus will enter a dormant period, and if the temperature is below 2℃, podocarpus is very prone to frostbite or freezing to death.

Solution: Move the podocarpus to a warmer place indoors to prevent cold wind from attacking it.

5. Long-term lack of fertilizer in podocarpus

If the water and fertilizer needed by podocarpus are not supplied, it is not easy to keep its leaves deep green, and the leaf tips tend to turn yellow.

Solution: Apply some acidic fertilizer in time, and watering with fertilizer liquid is best, applying little but often.

6. Occurrence of pests and diseases in podocarpus

The appearance of red spider mites on podocarpus leaves, or anthracnose, leaf spot disease, and scale insects, will all cause localized scorched yellowing of the leaves.

Solution: For red spider mites, you can spray with dicofol, hexythiazox, etc.; for scale insects, you can spray chlorpyrifos, methidathion, etc. for control; for anthracnose and leaf spot disease, you can spray carbendazim, thiophanate-methyl, etc. for control.

How to Water Podocarpus

1. How to water at different stages

Spring and summer are generally the seasons of vigorous plant growth, and because the temperature is high, transpiration is also relatively strong, so the water requirement is greater. Therefore, keep the potting soil in a moist state and do not let it become too dry. If you find it hard to judge by eye, you can touch the surface soil with your hand. If it is dry, water it; if the surface is wet, then the interior will not be short of water, so there is no need to water at this time, otherwise it is very likely to overwater.

In autumn, the water requirement is moderate. You can water once every two to three days and keep the soil slightly moist the whole time, which is enough to supply the plant's needs.

In winter, there is no need to say much. Most plants generally have little need for water, and at this time it is best to pause watering. Or if the potting soil is really too dry or the plant's leaves begin to look wilted, then water appropriately, about once a week.

2. Precautions

To prevent the leaves from drying up and dropping in a dry environment, you can spray some water around the plant, or spray some water on the leaf area. Of course, doing so can also wash away the dust all over the plant, making it look cleaner and more attractive.

In summer, do not water during the afternoon when the temperature is at its highest. Generally speaking, the two periods of morning and evening are more suitable.

According to the plant's degree of preference for moisture, you need to understand that both being too dry and too wet are bad for the plant. The most important thing in watering is adjusting the “degree.”

How to Fertilize Podocarpus

1. Podocarpus's requirements for fertilizer

Just as we can see from the robust appearance of podocarpus, its adaptability is equally excellent. It can live in very barren places and does not need much fertilizer. However, proper fertilizer can provide nutrients that flowers cannot absorb from the soil, so it still has a reason to exist.

2. What fertilizer should be applied

Natural animal manure is best, as it has no side effects and will not harm the surrounding environment.

For commercially purchased fertilizer, you can choose urea or other fertilizers with balanced nutrition.

3. Different treatments at different stages

When the plant is in the seedling stage, it has a relatively high demand for nutrients. In order to let it grow steadily faster, we should apply more fertilizer; once it has adapted to the surrounding environment and can grow steadily, the frequency of fertilization can be appropriately reduced.

In spring and summer, the plant's renewal and growth are relatively fast, so fertilizer should be applied at this time. You can apply some urea every half month or twenty days (a concentration of 0.2 percent is suitable), or animal waste.

In autumn and winter, especially in late autumn and throughout winter, the plant enters a period of slow development, and almost no fertilizer needs to be applied.

What to Do If Podocarpus Roots Rot

1. Water scientifically. Needless to say, although this plant relatively prefers moisture, it is afraid of waterlogging, so the amount of watering must be strictly controlled. Generally speaking, in spring and summer, water a bit more, just enough that the potting soil does not dry out. From late autumn to winter, the amount and frequency must be strictly regulated.

2. If it is caused by pests and diseases, this is relatively uncommon, because the pests and diseases of podocarpus generally target the leaves. If this occasional situation occurs, it is also relatively easy to handle; just buy specialized chemicals.

Watering and fertilizing are the two most important factors in a plant's survival process. Water is the source of all things, and watering is the foundation for ensuring a plant's survival, while fertilizing provides the plant with the nutrients it should have. Compared with other elements, these two are the basic principles of plant cultivation, so you must pay close attention to them.
