My Opuntia Ficus-Indica developed two healthy fruits a couple of months after flowering. Time for a dissection to extract the seeds!
1. Remove the fruits from the mother plant without touching them.
If the fruits are ripe (colourful and slightly wrinkly near the top), they should let go easily as you twist them off. I grabbed them with a folded up washcloth.
2. Remove as many glochids from the fruits as possible.
I ended up sacrificing the washcloth and a kitchen sponge, but the process was fairly easy. I just held the fruits in the cloth and rubbed them with a wet sponge over the kitchen sink. Don’t assume that all of the glochids have been removed. They haven’t.
3. Cut them open and scoop out the delicious stuff with the seeds in it.
The pulp is very juicy and it’s a bit of a mess. Opuntia Ficus-Indica have edible fruits and they taste a bit like sweet watermelon (do not eat your cactus fruits unless you’re 100% sure they’re not poisonous! Please ask an expert).
4. Wash the seeds thoroughly.
Now store them in a dry and clean tissue. I’ll sow mine ASAP because Opuntia seeds don’t stay fresh for very long.
