Some of the seeds require a summer condition before they germinates, I found the process of Scarification from a few links.

I first soak the seeds in GA3 (Gibberellic Acid-3) for 1 night before I prepare the burnt leaves process and soak the seeds in this solution using 60ÂșC and below water for 2-3 mins. Then, I sow the seeds in 2 part sand and 1 part peat.
