Brazilwood (Dracaena fragrans) Home Care Methods and Precautions
Scientific Name and Family
Brazilwood is also known as Brazilian iron, fragrant dracaena, and thousand-year tree. It belongs to the Agavaceae family, Dracaena genus. It is native to southwestern Africa. Commonly cultivated varieties are classified by different colored stripes on the leaves into mid-stripe, golden-edge, tricolor, rainbow, and silver-line varieties. Currently, the most common one on the market is the mid-stripe fragrant dracaena, also known as golden-heart Brazilwood.
Ornamental Features
Colorful and bright, tall and graceful, noble and elegant, with an exotic flair.
Purchasing Tips
In the north, it is better to buy in spring. For larger halls, you can buy potted plants with a height of over 1 m and 2-3 plants per pot. For smaller living rooms, you can buy potted plants with a height of 50-100 cm. When purchasing, choose plants with spreading, bright leaves, no dry tips, no scorched edges, and robust growth.
Best Placement Locations
① It can be placed long-term 1 m in front of a south-facing window where it can see sunlight. ② In a bright indoor spot. ③ In summer, it can be placed on a north-facing balcony or under tree shade.
Basic Habits
Light
It likes sufficient sunlight and has strong adaptability to light. It can grow in both strong light and shaded areas, but strong summer light can easily scorch the leaves, while long-term shade will make the leaf color dull and cause it to lose its luster or golden stripes.
Temperature
It likes a warm and humid environment. The optimal growth temperature is 18-25°C, and growth stops below 13°C. It can overwinter safely above 6°C.
Humidity
The most suitable relative air humidity is around 80%.
Soil
It requires fertile, loose, and well-drained soil.
Fertilizer
For fertilization, humic acid full-nutrient organic liquid fertilizer is better, and a compound fertilizer comprehensive in nitrogen, phosphorus, and potassium can also be used.
Cultivation Tips
April to September
Suitable growth period. When grown indoors, it should be placed in a bright spot. During the peak growth season, sufficient fertilizer and water are needed. Apply humic acid liquid fertilizer once every half month, and keep the potting soil moist but not waterlogged. If the air is dry when new leaves are emerging, spray the leaf surface 2-3 times a day to ensure the new leaves are bright and spreading. When maintaining outdoors in summer, provide 30%-50% shading.
October to March
In northern regions, when maintaining indoors, it should be placed where sunlight is visible, and it can grow normally if the room temperature is kept above 15°C. In winter, growth is slow, so fertilizer should be reduced and water controlled. Generally, after 2 years of growth, the pot should be changed and the soil replaced in spring. The growing medium can be peat soil plus 120% river sand and a small amount of rotted cake fertilizer or bone meal. Place about 3 cm of ceramsite or coarse sand at the bottom of the pot as a drainage layer. If the plant is too tall, the top of the main stem or branches can be cut off, and new shoots will quickly sprout below the cut.
Water Culture Tips
Brazilwood can also be grown in water. If grown in a glass container, you can enjoy both the leaves and the roots, which is especially charming. During the peak growth seasons in spring and autumn, add 0.5‰ full-element compound fertilizer to the water every half month, which can make the plant robust and the leaf color bright. If water culture growth is weak, it can be changed back to potted soil culture.
Propagation Tips
From April to October, cut off the branch tips removed from stem cuttings or new shoots with more than 6 leaves that have sprouted, remove several leaves at the base, insert them into clean river sand, water thoroughly, cover with a transparent plastic bag, place in a bright indoor spot, and keep the medium moist. Roots will form in about 1 month. Stem segments over 10 cm long can also be cut for cuttings and can root and sprout.
Special Reminders
The biggest difficulties in northern care are dry air and severe winter cold. During drought, special attention should be paid to spraying water on the leaves to wash off dust and increase humidity. In winter, attention should be paid to keeping warm and preventing freeze damage.
How to Care for Brazilwood
Because Brazilwood has a relatively tall plant type and grows quickly, households generally use medium to large pots for planting, and the potting soil is best as loose, fertile, well-drained sandy loam. Brazilwood does not have creeping rhizomes or tillering, so it is generally propagated by cuttings, which can be done as long as the temperature is not below 15°C. Before cutting, first cut off the old plant with a taller stem and fallen lower leaves, then cut it into 50-150 cm stem segments and insert them into moist bed sand. In about 1 month, they will root and grow into new plants. Brazilwood can also use water cuttings, but the pot water must be clean, and after rooting it should be transplanted into soil in time. When potting, apply some base fertilizer first to ensure vigorous plant growth. To make the shape more attractive, stem segments of different heights can also be planted in the same pot to create an uneven and layered variation.
Brazilwood has a wide adaptability to light. As long as temperature conditions are suitable, it can remain in a growth state all year round. However, it is best to stop fertilizing after September to let it go dormant in winter, and the dormancy temperature should be kept at around 13°C. If the temperature is too low, yellow-brown spots will appear on the leaf tips and leaf margins, reducing its ornamental value.
During the peak growth season, apply dilute liquid fertilizer once every half month, and frequently spray water on the leaf surface to increase air humidity. Young plants should be repotted once every early spring, and old plants can be repotted every other year. If the plant is too tall or the lower leaves have fallen off, the top trunk can be cut off to make it sprout new branches and leaves, keeping the plant at a moderate height.
Brazilwood Cultivation Methods and Precautions
Brazilwood, also known as fragrant dracaena and Brazilian iron tree, is a perennial evergreen tree foliage flower of the Liliaceae family, Dracaena genus. It is named dragon blood tree because its cut surface can secrete a colored sap, namely "dragon's blood." Brazilwood does not originate from Brazil, but from the tropical rainforests of Africa in the Guinea region. It has been widely introduced and cultivated in China.
The main stem of Brazilwood is upright, and the spreading leaf cluster is umbrella-shaped; the leaves are bright green or variegated, evergreen in all four seasons. Therefore, Brazilwood is regarded by people as a top-grade plant for indoor hall decoration.
1. Soil Selection for Brazilwood Cultivation
Potted Brazilwood on the market mostly uses fine sand soil, which is used by growers to allow the plant to fully develop roots, but long-term use is not good for plant growth. To make the plant grow vigorously, peat soil must be introduced in stages. It is not strict about soil requirements, and the most suitable soil is loose, well-drained, rich in humus, and slightly acidic (pH 5.5-6.0). A growing medium can be made from 4 parts leaf mold, 3 parts garden soil, 2 parts river sand (or perlite), and 1 part organic fertilizer.
2. Watering Methods for Brazilwood Cultivation
Brazilwood is relatively drought-tolerant, but if watering is insufficient and the potting soil is too dry, growth will be poor. During the growing season, the potting soil should often be kept moist, especially in the hot summer when growth is vigorous, watering should be more thorough. For household potting, follow "water when dry, stop when wet," that is, do not water when the surface of the potting soil is dry, and water thoroughly when watering. After autumn begins, watering should be gradually reduced, and during winter dormancy watering should be controlled. Too much watering will cause root rot.
During cultivation and maintenance, a certain air humidity should be maintained. If the air is dry, frequently spray water on the leaf surface to prevent dry and curled leaf tips and to keep the leaves clean and glossy. During the growth period, if water is sprayed on the leaf surface 2-3 times a day, the leaves will spread well.
During cultivation, keep the water clean. Water 1-2 times a week, and do not use too much water to prevent trunk rot. In high summer temperatures, spray to increase air humidity and spray water on the leaves to keep them moist.
3. Fertilization Methods for Brazilwood Cultivation
Potted Brazilwood should not be too large; it should be allowed to grow slowly to maintain an appropriate height. Therefore, less fertilizer should be applied. During the growth period, apply dilute liquid fertilizer once every 15-30 days, which can promote bright leaves. For variegated-leaf varieties, less nitrogen fertilizer or fertilizer with high nitrogen content should be applied, so as not to make the variegation color fade. Generally, apply rotted 20%-25% cake fertilizer liquid, or topdress with 0.2%-0.3% diammonium phosphate plus 0.3%-0.5% potassium nitrate, and also spray the leaves with an aqueous solution of 0.1% urea plus 0.2% potassium dihydrogen phosphate.
During the growth period, Brazilwood should be given appropriate foliar topdressing, spraying the leaves with 100-fold diluted nutrient solution once every half month. After several years of cultivation, when the plant is too tall or the lower leaves of the stem have fallen off and the tree shape is poor, pruning should be carried out. Repot or change the soil every early spring. In addition, excessive ventilation, drought, irregular watering, and excessive fertilization can all cause scorched leaf tips.
4. Temperature Requirements for Brazilwood Cultivation
The temperature required by Brazilwood is preferably 20-30°C. In winter, it can survive above 10°C, and growth stops when the temperature is too low.
As long as temperature and other conditions are suitable, Brazilwood can grow all year round. In high summer temperatures, appropriate shading is needed. In winter, the room temperature must not be lower than 5°C, but it is best to let it go dormant in winter at a dormancy temperature of 13°C. If the temperature is too low, yellow-brown spots will appear on the leaf tips and leaf margins.
5. Light Requirements for Brazilwood Cultivation
Brazilwood has a very wide adaptability to light and likes light while tolerating shade. However, long-term placement in an overly shaded indoor place can cause the leaves to turn yellow and make the variegation on variegated leaves fade. In spring, autumn, and winter, it should receive more sunlight, especially in winter when sufficient light is needed. In a bright indoor spot, it can be placed year-round. If it must be placed in a darker indoor place for viewing, after 15-30 days of viewing, it must be placed in a suitable light location for maintenance for a period, and then placed indoors again for viewing, and this cycle can be repeated. Brazilwood is afraid of direct strong light, so in summer, avoid direct sunlight. When maintaining outdoors in summer, use about 50% shading material to provide shade, so as to prevent the intense sun from scorching the leaves and affecting the ornamental effect.
6. Pest and Disease Control for Brazilwood Cultivation
The main diseases are soft rot, leaf spot, and stem rot. Improving ventilation and reducing humidity can reduce the occurrence of diseases. After onset, spray 75% wettable chlorothalonil 600-fold solution, or 70% wettable thiophanate-methyl 1000-fold solution for control. The main pests are red spiders, scale insects, and others, which can be controlled with 80% dichlorvos 1000-fold solution, or other appropriate insecticides sprayed for control.
7. Precautions for Brazilwood Cultivation
(1) Brazilwood grows vigorously and can form large plants. But if the plant is too tall, or the lower leaves fall off, the ornamental effect is affected and pruning is needed. When pruning, if it is cut off from the top of the plant or about 15 cm above the ground, buds will sprout below the cut and grow into new branches.
(2) The overwintering temperature for Brazilwood should be kept above 10°C. Silver-line Brazilwood has slightly stronger cold resistance, but the temperature should not be lower than 8°C. After late August, fertilization should be stopped to enhance overwintering ability.
(3) Brazilwood likes a high-humidity (70%-80%) environment. When new leaves are emerging, if the air is too dry, the leaf margins and leaf tips are prone to drying and curling, so spraying of the leaf surface and surrounding environment should be strengthened during the growth period. During the growth period, pay attention to sufficient water supply and keep the potting soil moist, but avoid waterlogging.
(4) When the plant grows too tall and the lower part becomes bare, the overly long part can be cut off. After cutting the stem, new branches will sprout below the cut on the remaining part, thus forming a more ideal plant shape.
8. Propagation Methods for Brazilwood Cultivation
It is mainly propagated by cuttings. Cuttings can be taken in all seasons except winter, but early summer is best. You can cut the leafy stem tip or the side branches grown after stem cutting, insert them into pure sand, and place them in a shaded place or with 50%-80% shading. Or use current-year or perennial branches as cuttings, cut them into 10-15 cm lengths, with each cutting having 4-5 nodes, and remove the basal leaves. Apply plant ash or sulfur powder to the cut end of the cutting to prevent rot. Use plain sand or vermiculite as the cutting medium. It can be inserted upright or laid flat for cuttings. Keep the temperature at 25-30°C, maintain a certain humidity, and roots will form in about 30 days.
Cuttings with terminal buds and leaves root easily, generally rooting and being potted in 25-30 days; stem segments root more slowly, sometimes requiring 60-70 days to root and grow new shoots. Rooting agents can be used to promote rooting, such as quick dipping with 1000-fold naphthalene acetic acid.
Brazilwood can also be propagated by seed. But it cannot maintain variety characteristics, especially for variegated-leaf varieties.
