The rubber tree's true name is actually Ficus elastica, which belongs to a species of tree and has become a popular plant nowadays, with many households having potted ones. However, many people are unsure how to water rubber trees, as they prefer moisture but dislike waterlogging. So, how can you tell if a rubber tree needs watering? Let's find out.
Signs of Water Deprivation in Rubber Trees
-
Wilting Leaves: The first sign of water deprivation is wilting leaves. If the tree is left without water for a long time, its leaves will dry out, and the trunk may become limp.
-
Shriveling Branches: The potting soil for rubber trees should never be allowed to remain dry for an extended period. If it does dry out, the branches may shrivel. To check for water deprivation, examine the branches. If they snap but still have some flexibility and moisture, watering can quickly alleviate the issue and help the plant recover.
-
Whitening Soil: Observe the color of the soil surface. If the soil has turned white from dryness, it's time to water. You can also lift the pot to gauge its weight; if it feels lighter than when it was freshly watered, it's time to water again.
Watering Tips for Rubber Trees
-
Summer Watering: In summer, when water evaporates quickly and rubber trees grow rapidly, they have a higher demand for water. Therefore, watering must be done promptly; otherwise, the leaves may turn yellow and wilt.
-
Winter Watering: During periods of low temperatures in winter, rubber trees require less water. Reduce the frequency of watering during this time, and it's best to keep the potting soil slightly dry. However, if the temperature rises above 10°C, the soil should still be kept moist, as the tree may drop its leaves if it becomes too dry.
-
Maintaining Humidity: In addition to watering the soil, regularly spray water on the leaves and around the plant to increase air humidity. This helps keep the leaves looking vibrant.
-
Watering Principle: When watering a rubber tree, follow the principle of "water when dry." Water thoroughly when the potting soil becomes dry.
Above are the methods to determine if a rubber tree needs watering. Rubber trees are popular indoor plants, and many people are unsure about watering them properly. Hopefully, you are now clearer on this matter.
