Rubber trees, scientifically known as Ficus elastica, are indoor potted plants with high ornamental value. Their unique tree shape, lush green leaves, and easy maintenance make them a favorite choice for many households and offices. Let's delve into the detailed cultivation methods of rubber tree bonsais to help you easily grow a healthy and beautiful rubber tree bonsai.
Choose the Right Rubber Tree VarietyWhen choosing a rubber tree variety, consider the size of the plant, its growth rate, and personal preferences. Common rubber tree varieties include green rubber trees and yellow rubber trees. Green rubber trees have bright green leaves, creating a fresh and natural atmosphere; yellow rubber trees have leaves with yellow patterns, giving them a more artistic feel. Choosing the right variety according to personal preferences is the first step to successful cultivation.
Choose the Right Pot and SoilAlthough rubber trees are not picky about pots and soil, choosing the right pot and soil contributes to the healthy growth of the plant. It is recommended to use ceramic or plastic pots with good breathability and drainage holes at the bottom. For the soil, a mixture of peat soil, decomposed leaf soil, and perlite that is breathable, well-draining, and rich in organic matter is suitable.
Light and TemperatureRubber trees prefer a semi-shaded environment but should not be kept in the dark for extended periods. During cultivation, place the rubber tree in a place with ample scattered light, avoiding direct sunlight. Regarding temperature, rubber trees thrive at temperatures between 18-30°C, and the temperature should not drop below 10°C in winter.
Watering and FertilizingWatering rubber trees should follow the principle of "watering when dry and damp when wet," avoiding waterlogging. In the hot summer, the watering frequency can be slightly increased. In winter, when temperatures are low, the watering frequency should be reduced. For fertilizing, applying a compound fertilizer once a month is sufficient. Be careful not to let the fertilizer come into contact with the leaves when fertilizing.
Pruning and ShapingRubber trees grow quickly and require regular pruning to maintain a good tree shape. During pruning, remove sickly, crossing, and overly long branches to promote healthy growth. Pruning can also create various beautiful shapes, such as cliff-style or curved-style.
Pest and Disease ControlCommon diseases and pests of rubber trees include leaf spot disease and scale insects. During cultivation, pay attention to the plant's growth condition. Once diseases or pests are found, take immediate action. Leaf spot disease can be treated with a 50% carbendazim wettable powder solution at 800 times dilution; scale insects can be controlled with a 40% dimethoate emulsion at 1000 times dilution.
