A Buying Guide For A Good Organic Fertilizer

Types Of Organic Fertilizer


The most apparent benefit of an organic liquid fertilizer for vegetables is its rapid penetration. Thanks to this fast-acting, the plants shall take no time to absorb the nutrients.

Another noteworthy point is that this option can blend well with other crop protection products in its liquid form and allow uniform application on the entire garden bed.

However, it is quite pricey for massive use and easy to go settled out without careful storage.


Dry fertilizers are a more affordable alternative. Although it takes more time for the thorough penetration than the previous option, this slow release of nutrition works wonders for heavy pre-plant use.

On the flip side of its sturdiness and easy storage, the granular sometimes does not manage to break out all nutrients and lead them to the plant’s roots. It also requires specific techniques during the application.

Once you use this type correctly following a proper routine, it promises to be the best vegetable fertilizer.

Best Organic Fertilizer For Vegetables (Granular And Liquid)

Sufficient Source Of Nutrients

The very first step you should take is to listen to your plant’s wishes.

You will want to look for a product that integrates an abundant source of minerals and vitamins for each type of plants’ efficient development.

The basic nutrients, including nitrogen, phosphorus, calcium or sulfur .etc are classified into 3 groups named macro, micro, and secondary nutrients. So make sure that your pick doesn’t miss any of them.

If you don’t have time to figure out the need for individual vegetables, there are still all-purpose options that can be used for every plant. Yet, their effects may be limited by such a wide application.

Compensative Ratio

All organic plant fertilizers are specified with the percentage concentration of the fundamental nutrients. You can easily find the product’s NPK ratio on its packaging, namely, Nitrogen, Phosphorus, Potassium, respectively.

For example, if the formula is 4-4-4, there is 4% amounts of nitrogen, 4% phosphorus, and 4% potassium in its components.

A formula that accounts for the soil structure will help you to fill in its missing pieces. It is also advisable that you look for other types of nutrients to accommodate all demands.

Spot-on Response To Your Needs

An accurate alignment between a product’s offers and its buyer’s demand will ensure its optimal value. Not only will the plants tell you what to look for, but the type of soil also needs profound consideration.

If you want to promote above-ground plant growth, a blood meal formula or fish emulsion will be second-to-none. In contrast, nothing could beat bone meal and phosphate rock in nurturing transplants and seedlings.

For gardeners who are upset about loosen clay soils, don’t hesitate to try a greensand or coconut coir product. Other solutions to improve the overall soils are undeniably compost and animal manures.

A Second Thought On Your Budget

Remember that gardening covers many steps and categories to be invested in, so don’t blank your wallet with just fertilizers.

Take one more look at your garden’s size and vegetables to calculate how much you will need to feed all of them. While big-sized products are often on offer with more promotional price, it could end up a waste if you can’t use all of them before the expiration date.

The old but effective way to ensure a wise bet is a quick pre-purchase research. The decision would be much easier and more time-saving when you list all of your needs, scan for the matching choices, then select the most affordable one.

Final Words

From my perspective, the Miracle-Gro deserves to occupy the top position as an excellent combination of all aspects, including functions, flexible use, and effortless storage.

Remember to take into account all vital criteria before your official purchase. An ideal pick should lend itself to the functions you want, the nutritions your vegetables need, and the price that your wallet can cover.
