How much do I use per watering?

One teaspoon per gallon of water, applied weekly along the drip line. First-season trees get one teaspoon a week; mature trees up to two.

How long will one bottle last?

At one teaspoon per gallon, a 32 fl oz bottle makes roughly 768 gallons of feed. A single tree fed one gallon a week would take about 14 years to use it up.

Can I use it on potted citrus?

Yes. For indoor or container trees, cut the dose in half or feed every other week.

Does it work on avocados too?

Farmer's Secret says the same formula works well for avocado trees, not just lemons, limes and oranges.

Is it better than granular citrus fertilizer?

Buyers who switched say they saw faster greening and new growth than with granular feed. Liquid feeds act quickly but need weekly mixing, while granules release slowly.

The best new price was $12.99 at Farmer's Secret as of November 7, 2026, with two stores carrying it. Check the price history before buying to see whether that is below the usual level.
