What if the leaves of the rubber tree turn yellow? Pay attention to these points: thick branches and thick green leaves

Rubber tree is an evergreen woody foliage plant, the leaves are large, thick leathery, glossy, round to long oval, dark green, light green back, placed in the home is a beautiful and vibrant plant, but sometimes there will be some diseases, such as rubber tree leaves yellowing or even lost leaves, and then I will say to the flower friends: what if the rubber tree leaves turn yellow? The solution, pay attention to these points, thick branches and green leaves!

1. Soil

At the initial stage of rubber tree growth, the basin needs to be changed once a year, and the basin diameter is larger every year. After growing for 6 to 8 years, the basin can be changed every three years. If the basin is not changed for a long time, the basin soil will be seriously consolidated and the soil will be poorly ventilated, resulting in asphyxiation and necrosis of the fibrous roots of rubber trees, unable to absorb water and nutrients, and causing plant leaves to wither and fall off. Pay attention to loose, well-drained and fertile humus soil when choosing basin soil. The container drainage holes for planting rubber trees should also be good, and it is very important to avoid stagnant water in the basin soil.

Solution: when the temperature reaches more than 15 degrees, turn the basin, cut off the dead roots, and shake off most of the persistent soil. Remove the yellowed leaves, cut the stem properly, replace the original consolidated basin soil with fresh and fertile culture soil, and often keep the soil moist, which can promote the re-emergence of new roots, restore health, and grow into multi-branched plants. In the future maintenance, it is necessary to keep the basin soil permeable and loosen the basin soil every 15 to 20 days while keeping the basin soil moderately moist, so as to avoid rotting roots or root atrophy caused by repeated watering.

2. Fertilization

Rubber trees like big fat and heavy water, and not applying fertilizer for a long time will cause malnutrition and cause the leaves to turn yellow.

Solution: when changing the basin, add an appropriate amount of base fertilizer, remove yellow leaves, and then apply liquid fertilizer every half a month, mainly phosphorus and potash fertilizer. Fertilization is usually applied in the spring and summer growing season, and the usual general fertilizer is the most suitable.

3. Temperature

The lowest adaptive temperature of rubber tree is above 6-8 degrees. If the room temperature is less than 5 degrees in winter, the withered and yellow leaves will occur.

Solution: to increase the room temperature through the winter, be sure to keep it above 6-8 degrees. In the ideal growth condition of the rubber tree, the best growth temperature is between 15 and 25 degrees, and the lowest temperature it can bear in winter is 4 degrees. No matter how low the temperature is, it is easy to frostbite.

4. Watering

Although the rubber tree is a water-loving and fertilizer-loving plant, if it is watered and fertilized too much, especially from August to September, when the weather is still muggy, too much water is watered and stagnant water is formed in the basin; or too much water is watered during the overwintering, and the plant is in a dormant period, transpiration is reduced, and the water in the basin can not be discharged in time; or if the raw fertilizer, big fertilizer and thick fertilizer are mistakenly watered, the rotten roots will occur due to water damage and fertilizer damage, resulting in withered and yellow leaves.

Solution: in winter, we need to keep the basin soil slightly dry, ensure that the basin soil drainage is good, avoid excessive watering, it is easy to cause root rot disease, other seasons can keep the basin soil properly moist, dry and thoroughly irrigated is the most suitable.

Okay, this is my summary of the reasons for the loss of leaves of rubber trees. I hope friends who love rubber trees and plants can help.
