Can Delonix regia be planted in the north?
The editor introduces knowledge about whether Delonix regia can be planted in the north and evergreen courtyard plants that do not shed leaves in winter. It's quite useful knowledge, recommended for collection!
Jacaranda is a tropical plant from the south with blue flowers, while the ones with red flowers are called Delonix regia. These plants have been quite popular in the ornamental plant market over the past couple of years, especially favored by young people. This is due to their beautiful plant shapes, which match various decorating styles. Some say that having a Jacaranda at home is like bringing a forest home.
To properly care for Jacarandas, several precautions need to be taken.
First, soil: Jacarandas prefer slightly acidic or neutral soil that is loose, well-draining, and breathable. The soil should not become compacted, and a mixture of garden soil, sandy soil, perlite, and a small amount of moderately decomposed sheep manure is recommended for cultivation.
Second, lighting: Jacarandas enjoy sunlight but can tolerate semi-shade. They can be exposed to full sunlight when the temperature is below 30 degrees Celsius, but growth will cease and they need shade when the temperature exceeds 30 degrees, receiving 50% scattered light.
Third, temperature: As a tropical plant, Jacarandas need to be moved indoors for warmth when the temperature drops below 15 degrees Celsius. Below five degrees, they can suffer frost damage. Thus, it's challenging to grow Jacarandas in the north with large temperature fluctuations, and they need to be placed in the warmest and sunniest spot in the house to survive the winter.
Fourth, watering: When the temperature is above 32 degrees Celsius, keep the soil slightly moist for Jacarandas. Long-term excessive moisture or waterlogging can cause root rot and death. When the temperature drops below 15 degrees Celsius, start controlling the water, allowing the potting soil to become lighter after drying out, then water to half capacity. Below 10 degrees Celsius, try to keep the potting soil dry, occasionally adding a little water to maintain some moisture. Below five degrees Celsius, do not water at all, and keep the soil dry throughout the winter; avoiding frostbite is the best outcome.
Fifth, pot selection: Choosing the right pot for growing Jacarandas is also important. The pot should not be too large, as excessive watering can lead to the soil remaining damp for too long and causing root rot. A pot that is too small can limit root growth, which is not conducive to the plant's development.
Sixth, during the growing season, Jacarandas should be fertilized regularly, with a focus on nitrogenous fertilizers. Regular pruning of the plant is also necessary.
For successful Jacaranda cultivation, temperature, lighting, watering, and pot selection are all crucial.
