Can become very large, with good care

My personal record was of this variety 8.10 meters (yes ka joke) How to reach this size?

- Breakfast the start planting
- Hoping for a warm spring or summer. The hotter the better
- The hotter the more water more, so do not be stingy with it, otherwise the growth will stop quickly and the flower forms.
- Finally, there were 20 liters of water per plant per day
- Weekly fertilize, I took Mairol universal fertilizer liquid
Remove weeds immediately, weekly earth aufharken -
- I made with earth a circle, so that the water remained long at the plant

And when you consider all this, can viell. Also you soon have a Monster sunflower in your yard, and the neighbors green with envy ;-)

Enjoy and good luck.
