Foxtails have been one of the quickest and easiest for me. That being said, a few in the bunch did take as long as 6 months...had about a 75% rate after a couple of months. It's possible the seeds aren't that fresh and that could explain the delay. I just bury mine half way in soil...leave outside in the shade and keep moist. Have patience...Z

I got 1 of 5 to germinate. That one is doing well, but it took months. I figure the others aren't going to go.

These were planted in containers, not baggies, outside.

My approach to scarify is first to secure the seed in padded jaws of a small vise. The you can use box cutter to slice through or a wood rasp to abrade through the hard seed coat.

Adding a teaspoon of potassium nitrate or soluble 20-20-20 to quart of soaking water can help.

Keeping tropical palm seeds continuously moist and warm, like 90F+, seems to be a major factor in germination speed and rate.
