When To Plant Sunflowers In Brisbane | A Review

#1 Autumn/ Winter: I was shocked when I planted sunflowers in both autumn and then a Brisbane winter and they grew happily along. During cooler months the key is heaps of sunlight. That means planting sunflowers where they get all day sun. If they are planted somewhere in the shade of a tree/house/covered balcony, they will not be happy campers and will start to droop or stunt.

#2 Spring/Summer: Sunflowers can and do grow well in Brisbane during the sweltering summer months, but it pays to protect them from the heat as much as possible during this time. I make sure to plant them somewhere that gets morning sunlight, but afternoon shade. They cannot take a full day of burning sun at this point of the year. Water morning and night to help them stay hydrated.
