Here are my first two Luffa cylindricas from our favorite Zonie! When she sent me the seeds, Jo (roadrunner) wrote:
I clip the corners of the gourd seeds [which she drew a diagram of] & soak over night before starting the seed in cups - or just put them in the ground.
As you can see from the cotyledons, I nicked the seed coat a little too roughly, but that sure didn't stop them from showing up! I also soaked them a bit longer (36-48 hours) because, well, the weather was nice the next day and I forgot.
Thank you, Jo!
