Thank you Keith - haven't thought about it.

Just wanted to provide an update here in case anybody else searches for this issue and ask a question: I saw some of those pods were cracked open so I harvested them by scooping them out. E. rig. cracked 1.jpg E. rig. cracked 2.jpg E. rig. scooped 1.jpg E. rig. scooped 2.jpg My question is, are the ...

Thank you Alejandro, I'm in Dallas, TX and will keep an eye on the ants as well.

Thank you MikeInOz.

Hi folks, After ~15 years of raising E. rigidissimus, I finally had some seedpods form after my plants flowered. I have a question regarding harvesting the seeds: Should I wait for these flowers fall and pods open themselves or am I supposed to cut the pods off the plant and open them myself? Please...

I showed these pictures to the owner of the nursery I bought it from and asked him what to do - he said it was an infection and that I should use systemic insecticide and pesticide.

Thank you all in advance...

Thank you for responses...

Thank you in advance...

Thanks a million Ian.

I thought I should stop watering during winter and water regularly during summer. That was new!

Thank you iann. What exactly should I do to "carefully" store them? In a paper envelope? Dark place? How about keeping them in refrigerator (although, I think in their native land, it never gets that cold)? Speaking of P. neliis, may I ask some more questions on cultivation, since you are ...

Does anybody know for how long P. nelii seeds are viable?

StrUktO, hob: Thank you..
