How to Choose a Great Vegetable Fertilizer

There are a few terms to keep an eye out for as you are comparing and contrasting labels. Make sure you double-check the bag or bottle to understand what you’re purchasing.

  • OMRI Listed. OMRI stands for “Organic Materials Review Institute.” It is their job to verify that the products going into plants and livestock care products comply with organic standards.

If you are interested in a truly organic vegetable garden, then make sure you see the “OMRI Listed” logo on the label.

  • Feeding Release Speed. Unless you prefer to keep a close watch over your veggies by applying fertilizer on a regular basis, the most convenient choice is to opt for a slow-release food.

These are usually granules that break down gradually over time, but some come in the form of powders like the Seagate Products Fish Fertilizer Concentrate Powder 42 Ounce Jar .

They release nutrients and a rate that is healthier for the plant and surrounding soil.

  • Coverage Area. Make sure the bag or bottle of fertilizer you purchase is enough to cover your entire vegetable garden.

Liquids like the Miracle-Gro LiquaFeed  hook up to your hose and allow you to spray your plants and vegetables, offering you a wider range of coverage that is also quicker to apply. Just make sure you purchase the special nozzle  for your hose to be able to use it.

Granules and powders are easy to spread but do require a bit more time to work into the soil.

Spikes are another quick and easy option since you just push them into the ground.

  • NPK Analysis. The NPK analysis, such as 14-14-14, listed on fertilizers refers to the amount of Nitrogen, Phosphorous, and Potassium that the mix contains. They are always listed in that order, too, so there will never be any confusion.

Different vegetables prefer different levels of each nutrient. But, most mixtures are formulated for general use with a mixture of vegetables. Do not feel that you need to find a perfect match for your plants. It is much more important to get some fertilizer down and keep an eye on how the plants are doing.

Specific vegetable fertilizers will have levels of each nutrient that are most appropriate for that plant and will tell you what type of vegetable it targets on the label.

Follow Applications Instructions Carefully

If you want to avoid burned leaves, then it is important that you follow the manufacturer’s instructions exactly.

We have seen so many gardeners complain of burnt foliage. Yet when we have tried the product and applied it as directed, it is never a problem.

Earthworm castings (i.e. their dung) contain water-soluble nutrients that come out of the worm in a richer format than they had before going into the worm. The result is plant food gold.

Harvesting castings is quite time-consuming. So, spend a little extra to have the work done for you. A product like this is worth your money.

These castings are especially helpful in areas where worms are few and far between and having started application early on in the growing season; the results were truly amazing. Very clearly this is one of the best fertilizers for vegetables.

Since it is free of GMOs, contains no chicken manure, is OMRI Listed, and CDFA-certified, you can trust that you are putting a truly organic product in contact with your vegetable crop.

Whether you live in a dry area or moist area, this is truly a phenomenal fertilizer that every organic gardener needs to try. ✔️ I'm sold!
