Brazilian Rosewood Care

Dalbergia Nigra

What is the plant

Dalbergia nigra produces a very hard and heavy wood, characteristically varied in colour from brick red through various shades of brown (medium to nearly black). Pieces that feature veins of black colouration called spider webbing or landscape grain are especially prized. Another distinguishing feature is its outstanding resonance. An evenly cut piece that is tapped emits a bright metallic ring that sustains. This property, combined with its beauty, has made Brazilian rosewood a favourite of musical instrument makers for centuries. Brazilian rosewood is highly resistant to insect attacks. There are many species in the genus Dalbergia that can be confused with Dalbergia nigra, but the latter can be recognised by its colour and resin. It may also be confused with Machaerium, which has a more compact parenchyma and lack large pores. Very little is known about the ecology and reproduction of the Brazilian rosewood.

How to Care for the Plant

Water
As a general rule, water your jacaranda tree when the top three inches of soil feels dry to the touch. These trees need consistent moisture throughout the year and often require additional watering during periods of high heat and/or dryness. If your tree is not watered deeply enough, it may not produce enough chlorophyll, causing chlorosis.
Pruning
Young jacaranda trees should be pruned to form one central leader (main trunk) for strength and stability. Otherwise, try to avoid pruning your jacaranda because this can force it to grow vertical suckers that can distort the tree's shape. Seasonal pruning should be limited to removing only broken or diseased branches.
Fertilizer
Feed your jacaranda tree annually with a compatible tree fertilizer, but be careful not to give it too much nitrogen, which can cause the tree not to flower. If you are fertilizing the grass under the tree, chances are the tree is getting a lot of nitrogen already.

Sunlight
For the best blooming, plant your jacaranda tree in a spot that boasts full sun, where it can get at least six to eight hours of rays a day. Smaller jacaranda trees can live in light shade if necessary, but a lack of optimal sunlight may impact the amount and vibrancy of their blooms.
Soil
Jacaranda trees will do best in well-draining, moderately sandy soil with a slightly acidic pH level. It's also tolerant of clay and loamy soils, but should not be planted in any mixture that is considered heavy and wet, or one that does not drain well. Water-logged soil can lead to an increased risk of root rot and mushroom root rot.
Temperature
Some jacaranda trees can be tolerant of the occasional cold weather (as low as 20 degrees Fahrenheit), but generally, this species does not thrive in climates with frequent freezing temperatures. They like a lot of heat and humidity, but can be vulnerable to trunk scald in areas with constant high temperatures.
