What if the leaves of Phyllostachys pubescens / asparagus turn yellow

Asparagus is graceful, scattered, slender and straight, which can purify the air, cultivate sentiment, and is good for healthy fengshui. Many flower friends grow it in their homes. Recently, I have seen many people complain that the asparagus at home is getting more and more yellow, so today the editor will introduce the reasons for the yellowing of asparagus leaves, prescribe the right medicine to the case, and see how we should deal with it.

1. The light is too strong

Asparagus likes semi-shade, avoid strong light, especially in summer to avoid direct sunlight, otherwise it will cause branches and leaves withered and yellow. The flowerpot should be moved to a cool place and water is often sprayed on the branches and leaves to increase air humidity. Asparagus is a semi-negative plant, and many flower friends think that asparagus is not suitable for basking in the sun, so it is a big mistake to keep asparagus in a backlit place for a long time. Asparagus is afraid of strong sunlight, which needs proper shade in summer, but the sun is not strong in winter. Long-term absence of sunlight will make the plant become weak and slowly turn yellow. Therefore, it is best to put asparagus on the sunny windowsill in winter to bask in the warm sunshine.

2. Long-term shade

If asparagus is placed in a shady environment for a long time, the plant will grow weak and turn yellow. If the indoor light is weak, asparagus can be taken to a place with strong light every few days to increase photosynthesis.

3. Improper watering

Asparagus likes to be moist but afraid of waterlogging, so it should keep the basin soil dry and wet, and generally water the topsoil to make it moist. More water is easy to rot roots, less water is easy to dry tip, in the dry season should be more to spray water to the leaves. Asparagus likes to be wet, but is afraid of waterlogging. Before watering, you should knock on the basin of asparagus. If the sound is clear and the soil on the surface of the pot becomes dry, you need to water it. If the sound is dull and the soil is moist, don't water the asparagus. If the surrounding air is too dry, the leaf tips of asparagus will become dry, withered and yellow, so you should keep asparagus away from air conditioning and heating, and sprinkle water on asparagus leaves and around potted plants every day to maintain air humidity.

4. Improper fertilization

If the application of topdressing is too thick or immature fertilizer is applied, it is easy to cause "root burning", resulting in leaf drying and shedding. On the contrary, if the potted soil is barren, the leaves will turn yellow due to lack of nutrients. The roots of asparagus are fragile, and it is easy to "burn roots" by applying immature or over-concentrated fertilizer, which leads to dry yellow and shedding leaves. If there is no fertilizer for a long time, the soil is barren and the leaves of asparagus will turn yellow. Therefore, asparagus should be thinner and more fertilized, and the rotten organic liquid fertilizer should be diluted and used according to the proportion of 2RU 1000.

5. Poor winter management

Asparagus likes to be warm and sunny in winter. In winter, if you put it in a place where no light can be seen for a long time, poor ventilation or cold, it is easy to cause withered and yellow leaves. Generally, the room temperature should be no less than 12 ℃, and it should be placed near the south window, and watering should be controlled properly. It is suitable for asparagus to grow at room temperature above 10 ℃. If the temperature is lower than 5 ℃, the leaves will dry up and fall. Flower friends can check the temperature at home. If the temperature is below 5 ℃, they should keep warm by bagging in time. If the temperature is between 5 ℃ and 10 ℃, the growth of asparagus basically stops. Watering should be reduced and no fertilizer should be applied to ensure sufficient sunshine. If the temperature is above 10 ℃, it can be maintained normally.

6. The position is not suitable.

If asparagus is placed next to heating and air conditioning for a long time, not only the leaves of the whole branch will turn yellow and fall off, but also the stem will dry up. Asparagus placed next to the computer TV for a long time will also cause the leaf tip to dry up, so it should be kept away from the air conditioning, heating, TV and computer during the maintenance of asparagus.

7. Harmful gas infection

Asparagus is afraid of smoke and dust, and if it encounters poisonous gases, its branches and leaves are prone to yellowing. In addition, if the plant is too large, the flowerpot is too small or damaged by insect pests such as shell insects, it will also cause branches and leaves to turn yellow, so the pot should be changed and controlled in time.

8. Infect diseases and insect pests

Once asparagus is infected with shell insects and other pests, it will also cause withered and yellow branches and leaves, so it should be controlled in time. When asparagus is infected with insect pests such as shell insects, its branches and leaves are easy to wither and yellow. Flower friends observe whether there are insect pests in Chinese bamboo. If so, you can dilute the scale and spray it on the branches and leaves of asparagus according to the ratio of 1RU 2000.

9. Stay away from radiation

Not only do people need to stay away from radiation, but the growth of asparagus also needs to stay away from radiation. Putting asparagus next to televisions and computers will make asparagus leaves and stems dry and turn yellow. Generally speaking, if asparagus is more than 5 meters away from the radiation source, it will be much less affected.

Salvage maintenance after yellowing:

Generally speaking, it is difficult to turn green after the leaves of asparagus turn yellow, and the sick branches and leaves will consume the nutrients of the whole plant. in this case, we should abandon the pawn to protect the car and cut off the yellowing branches and leaves to ensure that the new branches and leaves can grow healthily. Flower friends have understood why the asparagus at home is yellow, quickly cut off the yellow leaves and take good care of them. I believe that before long, their asparagus will be green and luxuriant!

Do you want to cut off the leaves of asparagus when they turn yellow?

Many people will ask, what to do with the yellowed asparagus leaves? In general, the yellowed asparagus leaves will no longer turn green. On the one hand, the weak leaves consume the nutrition of the plant itself, on the other hand, they are not beautiful, so we generally recommend cutting them off. In the process of pruning, you can combine the shape and pruning of the plant.
