How many species of Brazilian iron trees are there?
Do you know anything about it? There are various species of Brazilian iron trees and knowledge about the cultivation methods of Brazilian iron in the field of flowers and plants, which are very good tips and worth collecting!
Brazilian iron, also known as dracaena fragrans, is a perennial evergreen tree belonging to the dracaena family. In its native Africa, the Brazilian iron can grow to over 6 meters, and the potted plants we usually see are shrub-like. The trunk of the Brazilian iron is straight and robust, with long, sword-like leaves and golden heart or golden edge varieties. It is a large indoor ornamental leafy potted plant. Very suitable for placement in living rooms, studies, etc.
Brazilian iron prefers fertile, loose, and well-drained sandy soil, and can be planted using a mixture of decomposed leaf soil or peat soil + garden soil + pearl rock or river sand, in a ratio of 2:1:1.陶粒 and decomposed organic fertilizer can be added to the bottom of the pot when planting.
Brazilian iron prefers a warm climate and is not cold-resistant. The optimal growth temperature is between 20-28°C, and the wintering temperature should be above 5°C, as it is prone to frostbite when below 5°C for extended periods.
Brazilian iron does not require much light and can grow in bright diffused light. Therefore, it is very suitable for indoor potted plant cultivation. However, excessive shade can cause the leaf color to fade. Strong sunlight in the summer can also cause the leaves to turn yellow and the leaf tips to dry out, so appropriate shading is needed in the summer.
Brazilian iron prefers moisture but can also tolerate drought. Watering should follow the principle of "alternating wet and dry" - do not water until it is dry, and when watering, water thoroughly but avoid waterlogging. During high summer temperatures, it is also necessary to spray water on the leaves to increase humidity.
During the growing season, apply a balanced compound fertilizer with nitrogen, phosphorus, and potassium every half month. Avoid excessive application of nitrogen fertilizer, as it can cause the plant to grow excessively and the leaves to fade. In the autumn, apply more phosphorus and potassium fertilizer to improve the plant's cold resistance.
Common diseases of the Brazilian iron include leaf spot and anthracnose, while common pests include scale insects and red spiders. Ensuring good ventilation and air permeability in the environment during regular maintenance can reduce the occurrence of diseases and pests.
Brazilian iron, also known as dracaena fragrans, can be distinguished from another plant called dracaena. First, from the plant structure, dracaena fragrans has a thick and straight trunk with poor branching, while dracaena has a thinner trunk with good branching. Secondly, from the leaves, dracaena fragrans has long elliptical leaves with golden hearts or golden edges, while dracaena has long, narrow leaves that are green.
