Neptune’s Harvest Organic Hydrolized Fish & Seaweed Fertilizer

41HwQZMUwzL. SL500

This fertilizer is good for the beginning stages of vegetable plant growth.

Review

The most important thing to note is that the NPK ratio is 2, 3, 1, which is relatively low. Therefore, it doesn’t contain many nutrients as other products we have reviewed. In addition, it is made of a combination of fishmeal and seaweed.

However, it is very well balanced and will provide your plants with a good mix of foliage growth and bloom. Furthermore, this product is ideal for the beginning stages of plant growth.

This is an excellent fertilizer to use if you have soil that already contains a good deal of nutrients. This product won’t provide your plants with a full dose of nutrients, but it is a good supplement.

This is a liquid fertilizer, so you just have to mix it with the water and apply it to the soil.

Pros

  • Just mix with water and apply
  • Ideal for new plants
  • Ideal if you have nutrient-rich soil
  • 100% natural and organic
  • Made with fish and seaweed

Cons

  • Bit of a strange odor

This product is very easy to use; simply mix one-half cap of this product with a quart of water and then drench the soil of your plants. For the best results, use it once every two to four weeks.

This product also contains a relatively balanced ratio of NPK nutrients. This mix is designed both for foliage growth and for big blooms.

This all-natural and safe organic fertilizer comes in at a very reasonable price. It is an all-purpose fertilizer you can use for virtually any kind of plant.

Review

This fertilizer’s NPK ratio is 4, 6, and 2, ideal for most purposes. It contains enough nitrogen for a good deal of foliage growth, but not so much that it prevents blooming.

It also contains plenty of phosphorus and a good deal of potassium. These are both important for creating big flower and vegetable blooms. Moreover, it is gentle enough, and your plants won’t get burned.

The ingredients include feather meal, rock phosphate, langbeinite, greensand, blood meal, fish bone meal, and humates, as well as kelp meal.

ALL BIO – Organic Plant Food

519pQqrj2EL. SL500

This is a great organic vegetable and plant nutrient used for indoor and outdoor plants. It is certified 100% organic and ecologically safe.

Review

As mentioned, this product is certified 100% organic. It contains absolutely no toxic, synthetic, or man-made ingredients, so it is totally safe for your plants and for all edible fruits and vegetables. On that note, it is also safe for the environment and to use around kids and pets.

The NPK ratio is 2, 1, 1. This means that this fertilizer contains more nitrogen, ideal for the beginning stages of plant growth, especially foliage growth.

That said, this is not the best option if your plants are already flowering; if your plants are flowering, they need more potassium and phosphorus than they do nitrogen.

However, this product is loaded with specifically formulated amino acids for vegetables and edible greens. They allow your edible plants to grow bigger and stronger.

This is a powder fertilizer that you can either mix it in with your soil or dissolve it in water. Either way, it’s pretty easy to use. On that note, it’s also relatively cost-effective.

Pros

  • Easy-to-use powder
  • Ideal for vegetative and foliage growth
  • For all vegetables and edible greens
  • 100% natural and organic
  • Eco friendly and safe around pets and kids

Cons

  • The amount you get is very small

Joyful Dirt Premium Concentrated All-Purpose Organic Based Plant Food and Fertilizer

41r3ZnPC8SL. SL500

This easy-to-use plant food contains loads of nutrients and beneficial microbes. It is generally designed for ornamental plants, not vegetable gardens, but it works well for its intended purpose.

Review

This combination of fertilizer and plant food is designed to be used indoors and outdoors. However, it is really intended for leafy plants, but you may also use it for herb gardens.

The NPK ratio is 8-1-5. It contains a good deal of nitrogen, ideal for foliage growth. Therefore, it is not really designed for fruits or vegetables, and it doesn’t have enough phosphorus for big blooms.

However, it contains many other nutrients and microbes that help plants grow quicker, absorb more nutrients, and use less water.

These microbes will help protect your plants against pest and fungal infestations. Simply shake it onto the soil and water it.

Pros

  • Ideal for leafy plants
  • Can be used indoors and out
  • Natural and safe
  • Very easy to use
  • Contains beneficial microbes

Cons

  • Not the most cost-effective option around

Buyer’s Guide

Before you shop for organic fertilizer, there are a few essential points to keep in mind.

Types of Organic Fertilizer

There are a few types of organic fertilizer to consider. These include things like manure, bat guano, compost, rock phosphate, chicken manure, bone meal, blood meal, vermicompost, and more. We recommend researching the benefits of the specific types of fertilizer before you buy.

Synthetic vs. Organic Fertilizer

Organic fertilizers often have many secondary micronutrients that synthetic fertilizers do not contain. As a result, they’re generally much safer to use, especially for edible plants. That said, synthetic fertilizers usually contain higher amounts of NPK nutrients. As a result, they can nourish your plants for more extended periods.

Ingredients

Look for 100% natural and organic ingredients. There are hundreds of elements that fertilizers can contain, too many to list here. That said, nitrogen, potassium, and phosphorus levels are the three most important things to look for.

Application Method

There are three main application methods. Some have to be mixed with the soil before your plant is planted. Some come in granule or powder form that you place onto the soil and then water. Others come in liquid form that you mix with water. They all work just fine, and it just depends on your needs and preferences.

Cost-Effective

Of course, you want something that is economically feasible. Pay attention to the ingredients because that’s what matters. You don’t need to spend a fortune to get a good organic fertilizer.
