Why Use Citrus Fertiliser for Lemon Trees?

Lemon trees are nutrient-hungry and will reward you with bumper crops if given the right feed. Ordinary garden fertilisers often don’t provide enough magnesium, potassium, or trace elements essential for citrus health. A specialised citrus fertiliser is tailored to boost fruit production, promote shiny leaves, and prevent common issues like yellowing or fruit drop.

Citrus Food is widely regarded as the best fertiliser for lemon tree growth in NZ conditions. With an ideal blend of slow-release nutrients, it ensures your tree receives a steady supply season-round.

How to Apply Citrus Fertiliser

To get the best results, feed your lemon trees in early spring just as new growth kicks off, and again in late summer. Scatter the granules evenly under the dripline (the area beneath the outermost branches) and water in well. For trees in pots or PB3 Planter Bags (Grow Bags Online), follow the recommended dosage—you don’t want to overdo it!

Younger lemon trees or those grown in larger PB40 Planter Bags (Growbag) also benefit enormously from targeted citrus fertiliser. As your tree matures, these nutrients help maximise both root and fruit development.

Common Lemon Tree Problems and How the Right Fertiliser Helps

Yellowing leaves, small fruit, or sparse flowering are all signs your lemon tree is missing key nutrients. Citrus Food gives your tree the nitrogen, phosphorus, potassium, magnesium, and micronutrients it needs for all-around health. This keeps the leaves green and glossy, fruit juicy, and the tree more resilient to New Zealand’s variable weather.
