Sunflowers are pretty hardy plants, but the main thing to remember is they don’t like waterlogged soil so make sure you have good drainage and make sure they are exposed to around six to eight hours of direct sunlight a day.

Also, sunflowers can be easily damaged by strong winds, so if you live in a windy region it is worth growing them where they are offered some protection. Against a wall or fence for example.

If you notice the leaves of your sunflower turning yellow or brown there may be something wrong, so make sure you take prompt action.

Sunflowers take around 80 to 120 days to mature and develop seeds.
