How tall does African milkweed grow?

African Milk Tree ‘Rubra’ is a fascinating plant that can add a touch of exotic beauty to any indoor space. As a gardening and landscaping expert, I have had the pleasure of growing and observing this unique plant for many years. One of the most intriguing aspects of the African Milk Tree ‘Rubra’ is its impressive height potential. When provided with optimal growing conditions, this plant can reach towering heights of 8 feet or more.

I remember the first time I saw a fully grown African Milk Tree ‘Rubra’ in all its glory. It stood tall and proud, with its thick, succulent branches reaching towards the ceiling. The vibrant red coloration of the stems and leaves added a striking visual element to the overall appearance of the plant. It was truly a sight to behold.

To achieve such impressive growth, it is essential to provide the African Milk Tree ‘Rubra’ with the right conditions. Firstly, this plant thrives in bright, indirect light. Placing it near a sunny window or providing it with artificial grow lights can help stimulate healthy growth. I have found that a few hours of direct sunlight in the morning or late afternoon can be beneficial, but too much intense sunlight can scorch the leaves.

In terms of watering, the African Milk Tree ‘Rubra’ has a similar preference to its cactus cousins. It is a drought-tolerant plant that prefers to dry out between waterings. Overwatering can lead to root rot and other issues, so it’s important to allow the top inch or so of soil to dry out before watering again. During the winter months, when the plant is in its dormant phase, it requires even less water.

Temperature and humidity also play a role in the growth of the African Milk Tree ‘Rubra’. It prefers average room temperatures between 65-85°F (18-29°C). However, it can tolerate slightly cooler temperatures during the winter months. In terms of humidity, this plant does well in average household humidity levels. If the air becomes too dry, especially during the winter when indoor heating can cause low humidity, misting the leaves or using a humidifier can help maintain optimal conditions.

Fertilizing the African Milk Tree ‘Rubra’ is not as demanding as some other plants. During the growing season, which typically spans from spring to summer, I recommend using a balanced, diluted fertilizer every 4-6 weeks. However, it’s important to reduce or halt fertilization during the winter months when the plant is dormant.

Pruning the African Milk Tree ‘Rubra’ is not usually necessary, but it can be done to control the shape and size of the plant. It’s essential to use clean, sharp pruning shears and to make clean cuts just above a leaf node. This will encourage new growth and prevent the plant from becoming leggy.

The African Milk Tree ‘Rubra’ has the potential to grow quite tall, reaching heights of 8 feet or more when given the optimal growing conditions. With its stunning red coloration and unique succulent appearance, it can be a captivating addition to any indoor space. By providing the right amount of light, water, temperature, and humidity, along with occasional fertilization and pruning, you can help this plant thrive and reach its full height potential.
