Coffee is fruit, right?
A while back in [url=https://www.helpfulgardener.com/forum/viewtopic.php?p=112087#112087]this thread[/url], I mentioned that I planted cacti seeds over top of coffee seeds that were taking forever to sprout, and that the cacti seeds successfully sprouted.
Well, the little cacti seedlings have all turned red, flopped over and DIED!
... the GOOD news is ONE of the coffee beans that somehow ended up on the surface germinated (I could see a little root tip growing out) a few days ago, managed to wiggle its root into the sandy soil, and is now starting to lift up the bean off the surface as of this morning (this is the stage I call sprouting).
I'm visiting it often to cheer it on.
1/19 - Soaked coffee seeds in warm water
1/22 - 4 out of 10 seeds sank (presumable viable). Sowed them all in a pt. berry container in 2:1 sand:compost and set on Seedling Heat Mat.
2/15 - got bored and sowed mixed cacti and saguaro seeds on top.
2/23 - cacti seeds sprouted so moved from heating mat to under lights
<One coffee seed became exposed>
<cacti seedlings turned red, started to flop over and die off>
3/3 - 1 Coffee seed germinated
3/8 - 1 Coffee seed sprouting, lifting seed off the surface of soil. NOT a total loss on cacti seeds, some other cacti seeds are germinating....
