Review: Improve/saves citrus right from the start! Ten stars. - This stuff is amazing, I will definitely buy again and also check out their other products. This stuff does what it claims to do. My citrus trees are showing immediate improvement.
Review: New leaves on our tree…at last! - We weren’t sure our poor young Meyer lemon tree was going to survive. We’d planted it in full sun, watered it regularly, and had been using a different citrus fertilizer applied to the soil, but it didn’t have many leaves, and the leaves it did have kept turning yellow and falling off. I had never used a foliar fertilizer before and thought I’d give Jack’s a try as my last resort. I’ve been feeding our tree with this fertilizer for about 4 months now, 2 Tbsp. in 2 gallons of water in my watering can, applied to the leaves every Friday, with the excess falling onto the soil around the tree. And our tree is looking healthy again, with lots of new leaves and more tiny ones sprouting out! What a joy to see! (And a relief not to have to replace a $200 tree!). Highly recommended!

## Features

- 20-10-20 Analysis - Great for producing vibrant green leaves, strong branches, and more fruit in tropical fruiting plants.
- Many Ways to Feed - Citrus FeED can be used as a foliar or root feeding product. Great for spraying directly onto leaves, roots, or when used in a continuous feed system.
- Water-Soluble Powder – Powdered concentrates go further than liquid fertilizers. Simply mix your measured powder with water and you are ready to feed with multiple gallons of liquid fertilizer!
- Included Measuring Spoon – All Jack’s Classic fertilizers come with a convenient spoon to create the right amount of liquid fertilizer for your plants.
- Micronutrients - Added micronutrients supply your plant with the nutrition it needs for optimal growth and health. Unlike other fertilizers, additional feeding is not required.

## Questions & Answers

**Q: can you use this on cannabis ??**
A: Yes. Start to finish. Be sure to add calcium somehow. Dolomite lime added to soil works great. Look into "Dr Bruce Bugbee" on youtube.

**Q: Does this have a strong scent for use indoors?**
A: No strong scent

**Q: is it organic fertilizer?**
A: no it is not organic

**Q: Can I use these on my tomato plants**
A: This fertilizer is specifically for citrus plants and would not be the best fertilizer for tomato plants because it would not supply the nutrients needed for tomatoes.  See the following article:

Jack's is a wonderful fertilizer for citrus plants and mine have done really well with it.  I highly recommend it to be used on the plants for which it is designed!

### ⭐⭐⭐⭐⭐ Noticeable improvement in plants
*by D***0 on June 2, 2024*

This is a very easy to use product. You just measure out the powder with the enclosed scoop and add to the watering can. Just a week or so after first use I can already see a noticeable effect. Plants are fully, look healthier and have many more leaves and blooms. No real negatives I can see so far. Good product.
