Citrus trees laden with juicy lemons, oranges, limes and mandarins ready to be plucked from the branch are a quintessentially Kiwi addition to many home gardens. Tui Citrus Food is a blend of nutrients formulated to encourage healthy green foliage and large tasty fruit, and includes high levels of potassium – essential for fruit and flower production. Tui Citrus Food also contains magnesium to help prevent leaf yellowing – a common problem with citrus trees.
