Grow notes:

Although seed can be sown most of the year in many parts of Australia seed is generally best sown in spring or autumn, avoid the coldest and hottest months of the year. The optimum germination temperature for germination is around 18-22°C.

Cassia seeds germinate readily, however, they do have a hard outer coating which is impervious to water and generally germination will usually not occur unless the seed is scarified by abrading with sandpaper or pre-treated with boiling water first.

1. Place the seed in a container and pour in just boiled water and allow to soak overnight.
2. The swollen seed can then be sown, re-treat seeds that have not swollen.
3. Sow the seed 6-10mm deep and keep it warm & moist but not wet.
4. Germination should occur in 10-21 days @ 18-22C.

General note: Seeds of many plants are dormant and may require specific conditions or pre-treatment for germination.
Please do not be too hasty to discard seed that does not germinate, seeds will often lay dormant until the conditions are similar to their natural requirements for germination to occur. Containers put to one side will often surprise long after they were discarded.
