Turtle back bamboo is a tropical rainforest type of foliage plant, in the southern park or botanical garden, you can often see some climb to a few meters high turtle back bamboo, it will wind around the tree or wall upward growth, the leaves will grow larger and larger, it will look particularly spectacular, potted turtle back bamboo can also continue to grow tall.
If the potted turtle back bamboo at home has a perennial high temperature and high humidity environment, there is more scattered light every day to avoid exposure, coupled with the three seasons of spring, summer and autumn, it can grow quickly. If something climbs and grows, it can grow taller.
If you find that the leaves of the turtle back bamboo are curled, it is generally the following 9 reasons, let's see how to solve it.
1. Insufficient moisture
This is one of the most common reasons, if you often water insufficiently (watering is not thorough), or not watered in time, will lead to the turtle back bamboo leaves curl, once found this situation, you have to check the dryness and wetness of the potting soil, you can touch the soil surface with your hands to see if the drying has been avoided.
Workaround:
At this time, it is necessary to water once in time, and spray the leaves with spray-like water, watering must be watered thoroughly, and if the potting soil is cracked, it is necessary to loosen the soil first, and then water slowly, or water many times to ensure that the watering is thorough.
Check the wetness of the potting soil in a few days, check whether the leaves are spreading out, and don't forget to check regularly if the potting soil is dry. 2, the air humidity is too low
Most of the tropical foliage plants are more like high humidity environment, if the air humidity is too low, will lead to poor growth, raising turtle back bamboo is to simulate the environment of the tropical rainforest.
If the indoor humidity is below 40% for a long time, the state of the turtle back bamboo will deteriorate, the leaves will curl, and the edges of the leaves will turn brown.
Raising potted turtle back bamboo requires regular spray-like water to increase the humidity of the environment and also clean the leaves. It is also possible to open a small humidifier next to the turtle back bamboo pot.
Potted turtle back bamboo and other tropical foliage plants can be placed together, and the local humidity can be maintained at a high level through the transpiration "rainforest effect".
You can also put a tray at the bottom of the pot, the tray is filled with pebbles, put in a little water, potted turtle back bamboo on the pebbles, you can also continue to increase the humidity.
3. Too much watering
There are two cases here, one is that the pot soil is not drained well, and the other is caused by excessive frequent watering.
This condition is less common because too much watering generally causes the leaves to yellow and wilt rather than curl.
If you find that the potting soil is continuously wet, you should pay attention to draining the water in time, you can place the potted turtle back bamboo in a better ventilated place, the bottom can be suspended, you can let the potting soil dry as soon as possible, give a little soft scattered light.
If the situation is more serious, even to remove the topsoil, check whether the bottom of the rhizome has black rot, and deal with it in time.
After removing the rotten roots, the bottom of the plant should be soaked in the sterilization solution for half an hour, and then replanted with new potted soil.
4. Sudden change in temperature
This situation is also more common, such as the sudden high temperature and cold air effects, will lead to the turtle back bamboo leaves curl, to avoid the turtle back bamboo placed in too hot or too cold position, do not place it in the heating or air conditioning vent, extreme temperature changes will also lead to rapid loss of water, which is also an important reason for the curling of the back bamboo leaves.
Avoid sudden changes in the environment, do not raise it in a position where the temperature is too high or too cold, such as the temperature is higher than 35 degrees, and must pay attention to ventilation. If the temperature is lower than 10 degrees, it is necessary to control the watering, and if the temperature is lower than 5 degrees, it is easy to frostbite.
5. Long-term use of chlorine-containing tap water
In some areas, tap water will contain some fluorine chlorine compounds, which will kill some beneficial microorganisms in the potting soil, and if the turtle back bamboo pots use tap water for a long time to replenish water, it may cause the leaves to appear slightly curly and the edges of the leaves to wilt.
Tap water can be containerized, put for a day or two and then used, you can let the hydrochloric compound in the water volatilize. You can also add some beneficial microbial fertilizer to the potting soil, you can also improve these conditions, of course, with rainwater to replenish it is the best.
6. Infected with insect pests
The potted turtle back bamboo raised indoors may also be infected with pests, such as when the air is relatively dry, it may lead to the breeding of red spiders, which will make the leaves rough, and some yellow spots will appear on the back of the leaves, which will suck the sap of the plant, causing the leaves to turn yellow and dry, and also cause the leaves to curl.
Red spiders are particularly small, difficult to find, often will be missed, must be carefully observed, found that there are some small spots on the back of the leaves, the leaf surface becomes rough, it must be dealt with in time.
Treatment:
You can rinse the back of the foliage leaf with water in time, raise flowers indoors and do not want to spray, you can spray or apply soapy water, neem oil or medical alcohol.
In the outdoors, you can directly spray insecticides, infected red spiders can be sprayed, the common golden branches, pyridoxine, severe can be used fast mites, generally sprayed once in 3 days, sprayed 2 to 3 times continuously.
7. New leaves curl
In this case, there is no need to worry, because the newly grown leaves of the turtle back bamboo are curled at the beginning, and when the leaves grow slowly, they will gradually stretch out, which is a manifestation of the healthy growth of the turtle back bamboo.
8, the pot is too small
If the larger turtle back bamboo is raised in a small pot, the water in the pot soil will evaporate rapidly, and if the water is not replenished in time, it will cause the leaves to curl.
If you find that the root system of the turtle back bamboo has grown all over the pot, and some of the roots are exposed. The potting soil is particularly crowded, it is necessary to change the pot in time, and after the spring warms up every year, the temperature is above 18 degrees, and you can start to change the pot.
9. Too much fertilization
If the potted turtle back bamboo is over-fertilized, it will lead to excessive fertility in the soil, which will affect the pH of the soil, it will seriously affect the roots of the plant, resulting in the turtle back bamboo can not absorb water normally, which will lead to curly leaves.
If you accidentally use too high a concentration of fertilizer for the turtle back bamboo, resulting in the curling of the leaves, it is necessary to rinse the potting soil with more water in time to reduce the fertility in time.
If the situation is particularly serious and the roots have been damaged, it is necessary to remove the potting soil in time, cut off the damaged roots, rinse them with clean water, and then plant them with new potting soil.
