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

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

I brought my sick indoor lemon tree outside, let rainwater nourish it. After that, I used the citrus fertilizer 2-3 times. The tree revived and soon set lots of new flowers. The existing fruits grew bigger as well. Will buy again when run out.

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

Works great for my orange tree

I purchased this for a grapefruit tree which was planted 5 years ago and my dwarf lime tree planted 3 years ago. The grapefruit tree has produced great, large fruit, however, last year the fruit was small. I believe it was because of the very hot summer here in Arizona. This year about 1/3 of the leaves are yellow to green. I started using this product and I'm hopeful this will make a difference. I used a bloom and fruit booster from this company 2 years ago and it definitely made a difference. I rated this 4 stars because I'm very hopeful it performs well and improves my grapefruit tree and boosts my lime tree's growth. I will revisit this review in a few weeks after weekly use.

I wasn't sure what to expect but my vegetable garden exploded! My flowers are doing great too. I would recommend to any gardener!

Great product, easy to use.

This worked wonders on my yellowing lemon tree in just a few weeks. It’s now sprouting lemons and is lush green. We live in the Phoenix, AZ area and the soil needs help. This is it!
