sprouting loquat

Ok, I need experienced help.  
I planted 58 loquat seeds in 4" pots in my greenhouse, central Texas, watered each day to keep moist, compost soil (Not fluffy, but more heavy),  planted 3 months ago April 1.
Some in sunlight others in shade (both in greenhouse)

Only 3 have sprouted.  Some are still hard. Most turned to mush.

There must be some trick to sprouting these since I'm generally successful with other seeds.

Can any experienced loquat sprouters give ideas, or the conditions in which you were successful?

Thanks!

these were fresh seeds?

Yes.  From fresh fruit.  Some were kept in water for a week or two since I read citrus seeds needs to stay wet.  Others were planted as we ate the fruit.  The seeds came from my tree, and a friend's tree.
