Review: product - good product, fair price
Review: Great results - I use this fertilizer on onion plants in tall raised beds every two weeks before they start to bulb. Then no fertilizer at all. This one keeps them making huge foliage and they stay dark green and growing great even after I stop the application and only water every day a little. Very good fertilizer and I have used it for several years. I will buy more.

## Questions & Answers

**Q: How much is used per gallon?**

**Q: Can it be used on orange tree?**
A: Yes. It’s designed to increase leaf production in the early stages of the season. Normally used only once as leaf buds begin to appear. Thereafter, use a more balanced fertilizer

**Q: How many tablespoons should be used per gallon of water? Need it for fruit trees and tomatos...**
A: I have never mixed it with water. I just use it as side dressing for fruit trees and grape vines. Putting it around tomato plants causes excess vine growth and very few if any tomatoes.

**Q: Can it be used on lime tree**
A: It can be used as a source of Nitrogen for the soil around a lime tree. You would also want a source of Phosphorus and Potassium.
