After the false sunflowers have stopped blooming in midfall, prune the plants to about 2 inches tall.
you could also wait to prune them in the early spring after the threat of frost.
Many varieties get top-heavy and require staking.
Prune or pinch them back in midspring for a shorter, sturdier plant.
However, doing this will delay blooming for a couple of weeks.
Dividing your plants every two to three years will keep clumps from dying in the center.
Do this in either the spring or fall with these steps.
For spring, start seeds indoors four to six weeks before your last frost date.
In the fall, direct sow in mid- to late August.

Trimming the plants if they get too tall or look scraggly will also encourage further flowering.
But as always, keep an eye out for a couple of minor issues.
Crumpled Leaves
If you notice crumpled or otherwise damaged foliage, check for an aphid infestation.
Try removing aphids with a strong spray of water before turning to insecticides.
Remove mildewed leaves, prune for good air circulation, and use fungicides if the problem persists.
False sunflowers come back every year, but these flowers typically have a lifespan of around five years.
They can self-propagate by seeds, or you’re free to propagate them yourself to get new plants.
False sunflowers continue blooming for a total of about six to eight weeks in the summer to early fall.
