Podocarpus is a common ornamental plant in life. It is deeply loved by people because it is easy to plant and has good meanings of prosperity, health, auspiciousness and wealth. So what is the reason for the yellowing of Podocarpus leaves? How to remedy the yellowing of Podocarpus leaves? Let's take a look.

Why are the leaves of Podocarpus turning yellow?

1. Yellowing caused by excessive fertilization

When we see that the leaves of the entire crown of the Podocarpus are almost uniformly yellow, it means that the Podocarpus has been overfertilized, causing the roots to be burned and damaged, making it difficult to absorb water and nutrients to maintain the nutrition of the upper leaves, which in turn causes the leaves to slowly turn yellow and eventually die.

2. Yellowing caused by leaf spot disease

We know that leaf spot disease often visits Podocarpus, and it can be said to be a frequent visitor of Podocarpus. Of course, the occurrence of leaf spot disease is related to the growth environment of Podocarpus. Leaf spot disease is most likely to occur under high temperature and humidity. When leaf spot disease occurs, we can see that the leaves on Podocarpus are scattered and sparsely yellow.

Of course, in addition to the yellowing caused by these two situations, there is also root rot and yellowing caused by excessive watering and poor drainage.

How to remedy the yellowing of Podocarpus leaves

1. Cut off the yellow and dry branches and leaves, replace the potting soil in time, and then spray water on the leaves to maintain air humidity and reduce the evaporation of leaf moisture.

2. Manually remove the diseased leaves in time, and then spray the leaves with fungicides such as thiophanate-methyl and propiconazole alternately diluted with water once a week for two to three weeks.

How to plant Podocarpus seeds

The fruit of Podocarpus is beautiful, with a bright color from yellow to dark purple at the bottom, like agate. It tastes sweet, and Podocarpus fruit can also replenish qi and dispel wind and dampness, but it is slightly toxic and should not be eaten too much. The green particles at the top of Podocarpus are the fruit of Podocarpus. When the color of the fruit below turns purple, it means that the seeds are ripe, and they can be harvested and dried for storage.

In spring, soak the Podocarpus seeds in clean water for one to two days, and wait for the seeds to absorb full water, which will help increase the soil germination rate.

The soil for sowing Podocarpus requires looseness, air permeability, good drainage, and disinfection. Sprinkle the seeds evenly into the soil, leaving a certain spacing, cover with a layer of fine soil, cover the seeds, and attach a layer of straw on top to keep moisture and heat. If the weather is cold, cover with film for insulation.
