Mixing liquid fertilizer can be time-consuming, so I’d like to share with you a way that I have found to get more done in less time. In this video, I’ll show you how to use liquid fertilizer more efficiently.
As an organic gardener, I don’t have to fertilize much because I use a lot of compost, and the compost provides most of the nutrients my plants need. Still, I do like to come in periodically and add some supplemental fertilization.
My fertilizer of choice is usually liquid fish fertilizer. For years, the way that I mixed a batch was to add fertilizer and water to my watering can, one canful at a time. Out of each batch, I’d usually have enough to fertilize one bed. With all the beds that I have in my garden, this meant mixing a lot of batches. But I’ve since come up with a time-saver.

Mixing multiple small batches of liquid fertilizer is time-consuming. I’ve found a more efficient way.
Instead of diluting enough fertilizer to make one batch at a time, I use a large TubTrug to make 8 gallons at a time. I mix the liquid fertilizer with water at the same ratio I would use when making a small batch. Then, I dip my watering can into the tub to fill it up quickly. I can refill the can this way multiple times. When there is just a little liquid left in the tub, I can pick the flexible tub up and pour it into the watering can without spilling any.

I make one large batch of liquid fertilizer, then dip my watering can into the tub to fill it up quickly. I can refill the can this way multiple times.
TubTrugs have lines drawn on the inside that show you how many quarts or gallons it is holding. To make it even easier to see my target, I mark the 8-gallon line with a Sharpie.

When I’m not using my TubTrug to mix fertilizer, it has so many other uses, from carrying soil and compost to a container for your harvest. I’m sure you’ll also find it very handy to have in the garden.

TugTrugs have all sorts of uses around the garden. When I’m not using mine to mix liquid fertilizer, they come in handy for carting compost, soil, vegetative waste and more.
