Hi,
Gladioli: some of them are losing their flowers and on their place grows a kind of seedbulb? What can I do with it? Leave it and wait or does it need some action?

Cut the flower stem off, but let the leaves die right back before removing them.
Can I win seeds from these Gladioli?
Yes you can grow them from seed. Unless anyone here can help I suggest that you have a google for information.
You Have to let the flowers die and fall, then let the seed pod go brown and crisp. Split it opeb into an envelope.. But it can take upto two or three years to get the flowers.
When you dig up the corns (which you should do) you can remove the cornlets (spawn) which can also be replanted then lifted for the following year.
