Last night I looked at them, and one is about 6" tall with another growing right next to it, about 2" tall. There is one more half dead about 1" tall about 3" away, and the rest are gone.

I brought the container into the house, watered it, stuck it in plastic zip lock for a little humidity, and here are my questions.

1. Can the two that are growing together stay that way?

2. You need two plants for pollination. Will these two pollinate each other even though they are growing as one?

The lone, almost dead one, has one little green leaf, so if I can revive it, it is far enough away for separation. I'll use it for a pollinator if it lives, but...

3. These seeds came from the same plant, so do I need a different variety for pollination?

Thanks!

I say different seeds because some plants (I'm not sure if pineapple guava is one) are polyembryonic - many embryos / seedlings from the same seed (Blue Lilly Pilly is an example of poly embryonic-seeds) Think of this as identical twins (poly-embryonic) and fraternal twins (seeds from the same plant)

The other seedling may survive - pot it up separate and see. No harm in trying.
