I did it. It was a bit scary to cut it open but it seems to have worked so far. I took pictures during the process so I could share.
The fruit had opened a little more sitting at the house. It didn't seem to be a problem, let's hope.
Inside the red exterior was a soft pod.
and inside the pod, a gel like substance surrounding seeds.
I scooped it out and put it in a strainer to clean.
The seeds after washing off most of the gel.
I planted them in a plastic box that tomatoes came in, good suggestion Noel. I ended up using regular potting soil because I didn't have any compost around and I didn't want to wait any longer. I sprinkled a little more dirt over the seeds after I took this picture.
Finding a place for them was a problem. It needed to be where the dogs and cats couldn't get to it and where there was light but no sun. I ended up putting them in the guest bathroom. It has a skylight for light and the door is always closed to keep the cats out. Plus, it is easy to get to so I will remember to spray it and check it.
I hope some of them sprout. I'm not great with seeds, they intimidate me and I don't have a lot of experience with growing from seed.
