Wait until the flower spike dies back then cut it just above the leaf.
wait for the stem to dry up and cut it close to the leaf
If you cut the main flower back to the buds on the stem you will get a second flush of flowers.
Cut the flower stem back to the leaf below and you will get another flower later.
A great way to lengthen the life of cut flowers is to cut the stem each day very little and refresh the water everyday! You can also read more about care of plants at our website here: http://www.scottsflowersnyc.com
Cut off the old flowers the foliage will die back naturally in the Autumn.
Yes; cutting the stem back will produce more flowering branches. However, don't cut them when caterpillars are actively feeding. If you feel you need to cut them at that time, cut only 1/3 or so of the branches at once to leave food for the caterpillars.
you can make santan reproduce by cutting a stem and letting the cut part to absorb water, this encourages the stem to make roots and if you think the roots are good enough you can plant it as is.
To cauterize a cut flower, immerse the fresh cut stem end in boiling water for ten seconds, or hold it over a candle flame until the ends are sealed.
flowers... that have been cut...
If you mean cut from the plant - it's because they're no longer getting nourishment travelling up the stem from the parent plant. That's why they're packed in wet paper for travelling, and why you need to put them in water as soon as you get them home.
If you do not want the seed pods to develop, cut the stalk off at its base once the flower petals have dropped. If you don't mind the seed pods, wait until after the first frost and remove the stalk along with your fall garden maintenance routine.
Cut the spent flowers (deadhead) to keep the plant neat, promote growth (especially stem branching) and get a rebloom in the fall. Take care to nip off the spent flower, not the whole stem. If you look further along the stem, you will see tiny flower buds forming to take the place of the spent one, if given the chance. If a carnation goes to seed, it focuses its energy in developing the seeds instead of flowers. It is more efficient to multiply carnations asexually through cuttings or divisions, so there's no need to let the flowers go to seed.
