GRF 13-13-13 NPK Granular Fertilizer (3lbs.)

Q: Is this fertilizer good for Palm trees?

Yes, GRF 13-13-13 works well on palm trees!

Q: Can I use this on an established zoysia lawn?

While this answer depends on your location, generally 13-13-13 will work on zoysia lawns. The best time to use the 13-13-13 would be during the Spring or Fall season. However, if you properly water your lawn on a regular basis, you can apply it during the Summer every 50 to 60 days with an application rate of 5 pounds for every 3,000 square feet. We hope this helps!

Q: Do I have to mix it with something? Or can I mix a small amount with my plot mix and broadcast it with seeder?

We would not recommend mixing GRF 13-13-13 with plot mix and broadcasting it with a seeder. Usually the NPK should be added before the seeding stage or after for maintenance. If used before or after seeding, GRF 13-13-13 does not have to be mixed with anything. Adding secondaries and micronutrients, however, would greatly benefit your food plot more than just using 13-13-13 alone. Always make sure to check what seeds are in your plot mix to see what the best ratio of N, P, and K would be for your plot. We hope this helps!

Q: How do you use in raised gardens or containers?

For raised gardens, mix the 13-13-13 in the top 2-5 inches of soil at a rate of 3 Tbsp per 1 square foot or 1.5 pounds per 100 square feet. If the plants are already in the ground, sprinkle some 13-13-13 on the top of the soil and mix as best you can. For containers, follow the same instructions. For potted plants, use 1 Tbsp of 13-13-13 per gallon of soil. I hope this helps!
