Hi Tui, is there any way to increase the number of flowers on my mandarin (or any fruit) tree? Is it related to the fertiliser application frequency?

Hi Morag,

The mandarin, like other citrus plants, is a big feeder and requires regular fertilising for optimum flowering, fruiting and growth. Use Tui Citrus Food for your mandarins, and for your other fruit trees, a fertiliser with high levels of potassium as this is essential for fruit and flower production. Apply in spring and late summer each fruiting season. 

Happy gardening, Tui Team
