What do our clients say? 

Ralph and the Royal Knight AG team took the time to listen to my vision and work with me to acheive that. A more organic approach began by using RKAG Microbial supreme in the fall. Over the winter Rallph helped build a budget friendly carbon based fertilizer program. 8 months later in the middle of the summer heat wave, we are conserving water and still seeing top quality turf. Royal Knight AG soil health approach has given us piece of mind under stressful growing conditions and given golfers great turf at an affordable rate.

Frequently Asked Questions FAQs

Which fertilizer is best for me to use?

Our fertilizers are built for anyone to use! Our Flourish Line is our liquid formulations made to be mixed with water and applied to plant or soil.  Our Nourish line is designed more for experienced growers looking for even more concentrated products! Both are very safe to use and environmentally friendly.

Is this fertilizer safe to use on any plant?

Yes absolutely! Any plant that grows in the ground or in water you can help fertilize with RKAG formulas.  Not only is it safe for any plants but it is also safe around people and pets!

How much fertilizer should I use?

Read the product label and follow instructions per product. Often the Flourish products are 100% safe at 1-9 oz per 1,000 sq feet and Nourish products are 100% safe at 1 teaspoon per gallon or 1-2 pounds per acre.

Can I apply too much fertilizer?

If the product is applied drastically over label rate you may see some slight discoloration or chlorosis.  Please read the label for the recommended rates.
