## Description

desertcart.com : Farmer's Secret Citrus Tree Booster Fertilizer (32oz) - Super Concentrated - Formulated for All Citrus Trees Including All Types of Lemons, Limes, and Oranges - Outdoor and Indoor/Container Trees : Patio, Lawn & Garden

Review: Great for my trees - Been adding this to my bi weekly watering regimine. Trees are healthy and this stuff is nice and dark and very contracted which means it goes a long way and is full of good stuff
Review: A good fertilizer, but does not include all of the nutrients for optimum growth of citrus trees. - I grow a few different citrus trees in my basement garden under LED lighting. Although I have grown almost all of our veggies and herbs indoors for over 10 years, citrus trees are relatively new to me. Since I use Farmer's Secret fertilizers for some of my veggies and have been happy with it, I bought this fertilizer for my citrus trees prior to doing research on the nutritional needs of citrus trees. After doing some research of multiple sources, I found that citrus trees require nitrogen, magnesium, calcium, and iron for optimal growth and fruit production and tend to need more supplemental nutrients, described as macronutrients, than other plants. Nitrogen has the greatest effect on citrus growth and appearance; it is the element used most to produce leaves, flowers and fruit. Phosphorus, particularly concentrated in younger tissue, helps the citrus store and use energy and take in nutrients; it also is essential for cell division and growth. Potassium and calcium are used in relatively great amounts by citrus to produce leaves, flowers and fruits. Magnesium is crucial in photosynthesis and stimulates phosphorus uptake, while sulfur is a part of many proteins and improves root growth, vigor and hardiness. Iron is important for chlorophyll production. Reviewing the nutrient analysis on the label, this fertilizer lists iron, but does not include magnesium or calcium which are crucial elements in a fertilizer for citrus trees. I did find another brand of citrus tree fertilizer that includes all of the elements required by citrus trees, but it lacks a bit in nitrogen. When buying a fertilizer, it is important to know the requirements of the plants you are growing. In my opinion, this fertilizer is lacking some of the crucial macronutrients required by citrus trees, and would not be as effective as a fertilizer that includes them. In my opinion, this is a good fertilizer, but a supplement of calcium/magnesium may be necessary if your citrus trees indicate a deficiency. I hope this review was helpful for you

### ⭐⭐⭐⭐⭐ High performing product from great company
*by R***R on December 17, 2025*

Just buy the gallon and use it for everything to simplify. Only got to use it at the end of the season, but I've seen great results (followed instructions). I use this and calmag+ (includes all the other micro nutrients) to feed the soil. Check your PH and NPK analysis. Plants won't be able to absorb certain nutrients if you're PH isn't correct (6.0 for my citrus and 6.2 for everything else) or if you're too high on a particular macro nutrient (NPK). Had issues with a damaged container but customer service responded promptly. Nice to know people still know how to do business.
