I read that these two are on the slow and difficult side to grow from seed. But what the heck; I had the seeds, and have some little pots.
So they're sitting in the kitchen window bay now:
I put them in Miracle Gro Seed Starting Mix. Passionfruit seeds reportedly can take _months_ to germinate, so I lightly sanded a few of them, and left the others as-is. All these seeds came from fruit off my Mom's incredibly-productive vine, about 5 miles away ATCF. I ate the pulp and dried the seeds for a few months:
The PF seeds are about 3/16" deep.
The pineapple seeds came from store-bought fruit (from which I also attempted to root the crowns). Two of the pineapples I ate had a lot of seeds, so I just put them aside for a few weeks to dry. The pineapple seeds are about 1/8" deep.
These little pots have littler holes in the bottom, perhaps 1/8" in diameter. Should I bottom-water? Or should I mist the tops with a spray bottle?
How long do I wait before I give up?
