Daffodil question
 

My daffodils have finished flowering now ... it's spring here .:D...but I've never grown them before and I have a question.

I know that daffodils grow from a bulb, and the bulbs will double if not lifted after flowering and I was told to leave my daffodils where they are until the leaves start to dry off which they've not done yet.

Considering all that, my question is.....

At the top of the plant where the flower was, I see a large green bulb. Does this bulb contain seeds, and if it does what do I do with it? Do I cut the bulb off now while it's green and dry it out, or do I leave it until it dries on the plant?

as soon
 

as the daff is done blooming, before that green swelling
gets large, you should dead head it off.

If you give the bulbs a high phosphate fertilizer after blooming, you don't really have to lift them. They will continue blooming
year after year and increase. If not dead headed, the bulb will not have enough energy for next season. Leave the leaves intact until they are totally brown, as they make food for the next season.

If taken care of, they can go 20 yrs! Ihave some that old
and I have never lifted or moved them.

Bulbs need adequate water in the fall, as that is when they
start making the flower for the next spring. If there is drought
they may die.
