Hawaiian bamboo leaves are slightly yellow, what are the reasons for black spots on bamboo poles?
Reason:

1, nutritional deficiency

The yellowing of Hawaiian bamboo leaves may be due to lack of nutrition. It consumes more nutrients in the growing period, so it should be supplemented by fertilization in time. If the leaves are insufficient, they will turn yellow. Apply dilute fertilizer solution once every half month.

2, light discomfort

It may also be that the light is uncomfortable. It is resistant to shade and afraid of strong light. If exposed to strong light, the leaves will get sunburned and turn yellow. It should be moved to a place with astigmatism or semi-shade as soon as possible, and it can be recovered slowly with more ventilation.

3, watering discomfort

If the water is not changed for a long time, a large number of bacteria will multiply in the water, which will turn the leaves of Hawaiian bamboo yellow and even slowly rot until death.

Matters needing attention in Hawaiian bamboo culture:

1, soil

Bamboo in Hawaii has a well-developed root system, so it is very absorbent. When selecting soil, we should choose soil with good drainage and permeability, which is convenient for Hawaiian bamboo to absorb water and nutrients. For example, humus soil, soft garden soil or culture soil mixed with a small amount of base fertilizer can be used as the substrate for planting Hawaiian bamboo.

Step 2: Moisture

In the growth period of Hawaiian bamboo, a lot of water is needed, so the watering amount during the growth period of Hawaiian bamboo should be increased. However, attention should be paid to the accumulation of water caused by excessive water, which may cause bamboo root rot in Hawaii, and the number and frequency of watering should be controlled.

3. Lighting equipment

Hawaiian bamboo likes semi-shady growing environment. When cultivated in spring and autumn, the control of light time and intensity is not very strict, so it can be cultivated in astigmatism.

In hot summer, we should pay attention to the daily illumination time and avoid direct sunlight, otherwise it may cause leaf burning; In winter, the temperature is low and the light is weak. Therefore, Hawaiian bamboo can be placed in direct sunlight to supplement light and promote its growth.
