What is Allamanda blanchetii?
Allamanda is a tropical plant popular for its stunning blooms. The plant has a rapid growth rate and its trailing stems require some support to grow. It can grow as tall as 8-10-feet but you can prune it regularly to keep its size in check.
How to Propagate Allamanda blanchetii
Take a 5-7 inches long cutting from a healthy plant. Dip its end in a rooting hormone, and plant it in the garden or pot. Water the soil thoroughly and cover the cutting with a polyethylene bag to create a humid environment. Make sure it gets plenty of bright and indirect light.

Growing Requirements of Allamanda blanchetii
This plant does well in 5-6 hours of full sunlight on a daily basis. Avoid growing it in an area that’s shaded. For plenty of flowers, the more sun it is going to get, the better!
Water it deeply whenever topsoil feels dry to touch. Hold back watering rate during winters. Allamanda is quite sensitive to calcium-laden water, so consider using collected rainwater or make sure you keep the tap water overnight to let the elements settle down.
Use regular garden soil with ample organic matter. A peat-based potting soil is best for its growth. Alternatively, you can mix equal parts of potting mix and perlite/ vermiculite, and use it as a growing media.
This tropical plant does best in the temperature range of 18-32 C. Although, it can tolerate a temperature as low as 10 C.
