Peace,

Since I am visiting here....
Leave the seed pod on the stem as long as possible. The fruit will get large and turn a slight yellow color. When you pick it, separate all the fruit. Pick up each one and squeeze it between your thumb and finger. The seed should pop out. You can rinse them and plant!
Some people are sensitive to the juice, you may want to wear gloves while doing this.
