I just get sunflowers and somebody told me that they need constant hot sea to bloom ..but it looks the same.
sunflowers are an AWESOME cut flower.

if they have already be cut from the plant, give it a current, clean cut on the bottom of the stalk and next dip that in boiling wet for 10 seconds or so.

after put them in a jug with fresh marine (just regular cool water from the tap) that have a drop of bleach and also a drop of detergent (to avoid blight) in the marine.

give the stems a touch trim (do the boiled water piece again) and fresh water every three days or so.

that's it!

delight in!
In what form did you acquire the sunflowers??? Did you get cut flowers or plants or seed???? If cut flowers keep the sea cold to allow the flowers to last longer. Change wet daily and recut stems after a couple of days.

If seed, I just use a right potting mix and water as usual. It is sun warm the soil that triggers the seeds to germinate. After they stare to grow, maintain them in full sun adjectives day. Hope this help.
Answers:    Are they cut or are they within pots and you planted them? Need a lil' more additional info. Regardless, plain outmoded cool water will suffice. Ask yourself this give somebody the third degree... Does mother nature, when she turns on her elevated spigot to spray copious amounts of rainwater on the living flora of the world, use hot hose, or is it cool? I would say that it is the latter of the two and the plants, trees, and home-grown flowers do just fine. No requirement for "hot" water at adjectives... And I've never been scalded by rainwater hold you?... Hope this answers your question.

If they are cut flowers stir 1 teaspoon of fruit fresh in the wet, they will last much longer.
