My seeds are sprouting! Why do they need fertilizer?

If you’re a new to growing, after you get your seeds – or sprouts – into the ground, it’s easy to become overwhelmed with the varieties of amendments, nutrients, and fertilizers available. The choices can seem overwhelming, and the packages all seem to read like your (long-forgotten) High School science lessons, with nitrogen, phosphorus, and potassium showing up on all the bags, and all with different ratios!


Fortunately, each bag you see should tell you what the mixture is best for; with the letters NPK and a three-digit number prominently displayed. For example, if you wanted to purchase an all-purpose fertilizer for your grow with equal parts NPK (nitrogen, phosphorus, and potassium), then you might choose a product that had a ratio of 4-4-4. If you were looking for something that would help your sprouts during transplanting to promote root development, you would want a higher middle number such as a 2-8-4.

A quick, and by no means complete, way to thing of these three main nutrients is:

Nitrogen helps to support the leaves and stems. You may want to bump up the nitrogen if the older leaves are turning brown and the stems are especially slender.    

Phosphorus supports the root system and flowers. If you notice the flowers drooping and that the undersides of the leaves often have purplish cast to them, a little extra phosphorus can be just the thing to perk your growing plants up.

Potassium deficient plant

Potassium makes a big difference in the health of the leaves. If there’s a lack of potassium, you’ll notice that the lowest and older leaves look wilted or scorched, often cupping downwards from the stem. Spotting along leaf stem may also be apparent.

Once again, these three elements are just the basics, they are considered the primary macro-nutrients. Plants also need other elements, micro-nutrients, to achieve successful development. Magnesium, Calcium and Iron are also key factors in garden health the lack of which can cause weakness in your plants.

One of the best ways to get these micro-nutrients is to use sources that are naturally derived to support the overall soil complex. The analysis of these substances is often much lower than the synthetic varieties but more compatible to my labor force of worms and other microorganisms like bacteria and mycorrhizae. Natural fertilizers build soil structure because they are of an organic base. They improve aeration, hold moisture and nutrition better and complement the growth of the beneficial organisms. Using natural products is also a bonus for growers who place importance on keeping their grow organic, especially if they’re growing food!
