How are your fertilizers produced?

Our main five fertilizers include components that are mined in Chile, Israel and the Netherlands and factory-manufactured in the United States.

How much fertilizer should I apply?

Our fertilizers are ultra concentrated. For water-soluble fertilizers, you need only dissolve a small amount (as indicated on the label) in water and then irrigate your plants they way you normally would.

Can I skip dissolving in water and just sprinkle water-soluble fertilizer on the soil surface?

No! Your plant would suffer a fertilizer overdose this way. Always dissolve in water, and only use the amount recommend on the label.

Mulberry Fuel is Fantastic!

Just received my Mulberry Fuel. Immediately went out and put some on my mulberry trees. I’ve used this company before. I have their Banana Fuel. Banana trees look great. I’m sure this Mulberry Fuel is going to make my trees fruit like crazy. Thanks for making a fantastic product!

Really amazing stuff. It works!!

This really does work. My newly planted mulberry was looking so sad. I gave it a couple weeks to get a little over the transplant shock and then used this fertilizer and wow. It has greened right up. It’s started new growth and it looks so healthy now. I will definitely purchase again!

Great for berries and acid loving plants

Perfect for my prolific kiwi vines. Not only a fertilizer but a soil conditioner for plants that prefer a more acidic soil.
