Mr_bobo_ What a beautiful tulip bed! I love all the different kinds! Can I set up shop in your garden to practice my Van Gogh reproductions?
Noob, sadly they will only bloom once a year, but will come back year after year for a brief and beautiful display, with very little fussing.
If they are in the ground you can cut them back once the leaves all die and they'll come back next spring. If they're in a pot you may want to dig them out at that point.
You can cut them, but cut tulips do not last and you'll enjoy them for much longer if you leave them on the plant. If I had as many as mr_bobo i'd probably bring some in though!
Tulip bulbs form individual sections, kinda like garlic. So you simply split the individual "cloves" up and each one will become a tulip plant. Mine usually begin to sprout in the paper sac in the shed before I even think about them, and I end up giving away tons of little tulip plants. I'd say each bulb produces about a dozen new plants when broken up.
