 What To Look For In The Best Organic Fertilizer

Without the right choice of fertilizers, you cannot get the desired results. That is why we have presented you with a guide for buying the quality one.

The best organizer is available in different types.

  • Fish meal- It contains phosphorus, nitrogen, trace elements, and potassium.
  • Blood meal- It can release nitrogen and trace elements.
  • Animal manures- You can find a high amount of microorganisms in these manures.
  • Shellfish meal- This fertilizer contains micronutrients, phosphorus, nitrogen, and calcium.
  • Rock phosphate- It is the best fertilizer for blooms, and thus, you need to buy it for the flower garden.

To purchase the organic fertilizer, you can focus on a number of factors-

Type of soil

Sand, clay, and loam or holy grail- these are three ways in which we can categorize the soil. However, in most cases, our garden soil has a combination of sand and clay. While clay soil is highly fertile, it causes drainage problems. Based on the type and nature of the soil, you need to pick the right fertilizer.

Dry fertilizers

Organic fertilizers, available in dry powder form, have only ingredient (steamed bone meal, blood meal, greensand) or a combination of potassium, nitrogen, phosphorus, and micronutrients. You can choose a dry fertilizer for your flowering plants to increase the number of bloom. Moreover, this fertilizer helps in the development of strong roots.

Liquid fertilizers

Most of the plants have the capability of absorbing liquid fertilizers through stomata and roots. You may apply this liquid solution to the leaves and soil. In fact, during drought and after transplanting, you can use the liquid fertilizer. Thus, look for the best liquid organic fertilizer with a commercial blend.

Liquid versions act faster than that of the dry ones. For instance, during the late summer season. You can prefer the liquid solution as the best organic fertilizer for the vegetable garden.

Check out the NPK

NPK refers to the macronutrient blend of phosphorus, potassium, and nitrogen. While buying fertilizer, you can find some numbers on the package. It indicates the percentage of elements. For instance, the ratio 4-6-2 denotes 4% of nitrogen, 6% of phosphorus, and 2% of potassium. Nitrogen promotes vegetative growth, while phosphorus help with the development of fruits, flowers, roots, and seeds. Potassium can make the stem sturdier and resistant to diseases. Secondary macronutrients of fertilizers are sulfur, magnesium, and calcium, and they are available in varying amounts.

Blends or single ingredient- Which is the better choice?

Everything depends on the needs of your plants. Fertilizers with a single ingredient are useful while your plants are developing into a mature one. For instance, you may choose a feather meal for your heavy feeding plants, like corn, to enrich them with nitrogen. Similarly, you can buy phosphorus-filled fertilizer for beautiful blooms.

Fertilizers with blends of different macronutrients serve the general purposes of your garden. You can invest in them for your houseplants.

The multipurpose blends are the perfect choice for most of the gardeners to save time.


What is organic fertilizer? Why is it better than synthetic ones?

Organic fertilizers are animal-derived or plant-derived products. You will also find mineral resources to stimulate plant growth and increase soil fertility. Organic and natural fertilizers maintain the best soil health. However, chemical-based synthetic fertilizers can cause depletion of soil microorganisms. The buildup salts can damage microbes. These fertilizers can leach into canals, resulting in the creation of dead zones.

Conversely, organic fertilizers serve different purposes by providing plant nutrients, feeding microbes, and optimizing the growing conditions.

Which vegetable plants need a good amount of fertilizer?

The heavy feeding ones are broccoli, cabbage, celery, cauliflower, cucumber, leeks, kale, lettuce, peppers, spinach, tomato, squash, pumpkin, and melon. On the other hand, the light feeding ones are beet, bean, carrot, pea, onion, potato, turnip, and radish.

 Each type of fertilizer has different effects. How do I know that?

Animal manures are best for promoting your soil conditions, while alfalfa meal and blood meal accelerate the composting process. Coconut coir works perfectly for loosening clay soil, whereas colloidal rock phosphate helps in binding sanding soil. A bone meal with phosphate rocks can make your plant roots healthier and stronger.

My pet has a chance to eat my fertilizer. What will I do?

You can look for fertilizers that are pet-friendly and do not have harmful chemicals. Pets do not have self-controlling ability, and while they find something tasty, they can consume it instantly.

How do I know that I have chosen the wrong amount of nutrients for my plants?

A very high amount of nitrogen can show some symptoms, like the growth of dark green foliage, burnt leaf, and no blossoms. Too little amount of nitrogen makes the plant leaves yellow.

Lack of phosphorus makes the leaf color red, purple, and green. Stunted growth is another symptom of phosphorous deficiency.


Now, you can easily find the best organic fertilizer for your flowering plants, vegetable plants, shrubs, and lawns. The reliable organic fertilizer packages will ensure the highest level of yields. The industrially produced synthetic fertilizer may harm your plants. That’s why you can rely on the organic version of fertilizer. The commercially available organic fertilizers have the proper amount of nutrients. Your plants will grow at a faster rate, and you will find the best result from your efforts.
