Cassia javanica seeds will usually germinate in 7-90 days. Sow Cassia javanica seeds about 13mm deep in a Well drained seed sowing mix at about 22°C. Cassia javanica seeds have a hard seed coat that is impermeable to water, and which prevents the seed from imbibing.

Flowering: During the hot weather (April-May) the tree becomes most conspicuous with its pendulous inflorescence of golden yellow, mildly scented flowers. The tree remains leafless at the commencement of flowering and the end of the flowering season; the leaves start to appear.

Grow cassia in well-drained soil that isn't prone to standing water. Cassia tolerates and grows well in most moderate-quality garden soil. Space plants 3 to 4 feet apart from each other and other nearby plants. Cassia also grows well in large pots filled with standard potting soil.

After you have scarified the seeds in preparation for cassia tree propagation, soak them in cold water for 24 hours. Plant each seed in its own gallon (3.8 L) pot with drainage holes on the bottom. Fill the pots with lightweight, sterile medium. Sow the seeds 1 inch (2.5 cm.). . . . .364011234630!]0000000000000009783314145519!]
