The orange coating on them inhibits growth, so they must be soaked and scraped before planting.
It takes months before the seed coat cracks and a root emerges, then a tiny frond. Exciting.
A squirrel destroyed my first successful seedling when I put it outside for the summer.
I started over when there were more seeds. These seedlings are 2 years old, a long wait.
I have not decided whether I'll try to grow more cycads from this year's seeds. There's a little new plant growing beside an azalea I planted nearby the original cycad that I think came from a seed I disturbed when I dug there. I may try just putting them into the ground, using enough seeds so the squirrels and I can share.
Another way to grow cycads is by division of the pups growing around a plant. I successfully rooted 4 pups off Mrs. Cotele's cycad one year, then destroyed one by tugging it out of the pot to look at the roots. I put the pup into the ground, anyhow. This summer the remains of that pup put out a new frond. I still don't know whether the pups that did root and grow are male or female, they've never bloomed.He-Who-Mows ran over the smallest one with the mower. I'd cut the cold-bitten fronds off and I guess he thought that meant I didn't want it despite it having a little clump in the center. I'm waiting to see what comes from the roots next spring, if anything. It was cut awfully close to the ground.
