Citrus Tree Nutrition
Stop settling for yellowing leaves and small harvests. Our professional-grade formula eliminates the guesswork, delivering the precise nutrients your trees need for deep green foliage, explosive flowering, and heavy fruit sets that actually stay on the tree.
Excellent for lemons that need stronger foliage, flowering and fruiting support.
A strong fit for backyard lemon trees, potted lemons and established productive trees that benefit from regular citrus feeding through active growth, blossom and fruit development.
Great for active lime growth, blossom support and seasonal fruiting.
Ideal for Tahitian lime, kaffir lime and finger lime trees grown in the ground or in large pots where reliable citrus nutrition helps maintain healthier growth and better crop performance.
Supports greener foliage, stronger flowering and better orange crop development.
Well suited to sweet orange varieties and home orchard trees where balanced citrus feeding helps maintain healthy foliage, blossom strength and more dependable fruit production.
A strong option for mandarins carrying flowers, buds or developing fruit.
Useful for mandarin trees that need support through active growth and crop development, especially where the goal is healthier foliage, stronger flowering and more reliable fruit set.
Suitable across a wider range of citrus trees beyond the main household favourites.
A great fit for home growers feeding several citrus trees at once, including grapefruit, cumquat, pomelo and mixed citrus collections across one yard or home orchard.
Best used when citrus trees are actively growing, flowering or developing fruit.
Especially useful during the main citrus feeding periods when trees need support for greener foliage, blossom development, fruit set and healthy seasonal growth across the year.

A potassium-rich citrus fertiliser (often searched as citrus fertilizer, lemon plant fertilizer or lemon tree fertilizer) designed to support healthier growth, stronger flowering and better fruit development in citrus trees. 6-2-12 keeps nitrogen steady for leaf flush, phosphorus lower for balance, and potassium higher to support fruiting performance.
The 6-2-12 ratio is set up for citrus feeding patterns: nitrogen supports canopy and new leaf flush, phosphorus supports roots, and higher potassium helps the tree perform when it’s flowering and carrying fruit. This is why a citrus plant fertilizer with extra potassium is commonly chosen over a general high-nitrogen fertiliser.
What citrus is it for? Suitable for lemon trees (Eureka, Lisbon, Meyer), lime trees (Tahitian/Persian, Key lime), orange trees (Navel, Valencia, Blood orange), mandarins, grapefruit, kumquat, calamondin/calamansi and finger limes. Works for both in-ground and potted citrus.
