Why Did We Like It?

Many gardeners shy away from using fertilizers for several reasons. They might be too harsh for their soil, or they may be inconvenient to use. But you need not worry about that with Miracle-Gro Shake’ n Feed.

This fertilizer comes in a ready to use 4.5 lb container. You need to apply it just once in three months, along with regularly watering your plants to ensure proper growth. Moreover, the recommended rate of application is ½ cup per 10 square feet, which eliminates wastage.

Coming to its convenience of use, the fertilizer can be applied straight out of the bottle. There is no need to pre-mix or apply anything else to it. Simply pour the recommended amount on the soil, gently mixing it in, and continue watering your tomatoes.

The mix contains kelp, earthworm castings, feather meal, bone meal, and calcium. All these ingredients help tomatoes grow healthy and plump.

What Could’ve Been Better?

Honestly, this fertilizer is excellent and does the job well. Since it is a slow-release formula, it doesn’t burn the roots. That being said, it’s important to water the plant continuously to avoid frying the roots. You might need to apply more (or less) than the recommended dose for optimal results.

Pros
  • Slow-release fertilizer doesn’t burn the roots
  • Easy to apply
  • No harsh chemicals
  • Fast-working formula
Cons
  • Might need to increase or reduce the recommended dose
  1. Jobe’s Tomato Fertilizer Spikes

Why Did We Like It?

Feeding fertilizers to your beloved tomato plants doesn’t have to be an ordeal anymore. Jobe’s Tomato Fertilizer Spikes have been designed specially for convenience. The pre-measured spikes can be inserted into the soil and left there to feed macronutrients to tomato plants slowly.

The best part about these fertilizer spikes is that they provide a mess-free experience. There is no runoff, no toxicity, and no hazards. Moreover, the spikes don’t have any offensive odors that will make the soil or your fruits smell funky.

Each spike feeds tomatoes for about eight weeks, after which you can reapply a new spike. There are a total of 18 spikes in each package.

Lastly, if you’re worried about storing the spikes safely – don’t be. The manufacturer has thought of that too! Each package is waterproof and resealable, enabling you to store the spikes without worrying about them wasting away.

What Could’ve Been Better?

Although these spikes claim to have all the necessary macronutrients for growing healthy tomatoes, we did notice an ingredient was missing – calcium. This ingredient is essential for blooming tomatoes, and without it, it seems like a significant ingredient has been left out.

Pros
  • Easy to use
  • Slow-release formula
  • Fast working results
  • Each spike is long-lasting
Cons
  • Does not contain calcium
  1. Jobe’s Organics Fertilizer

Why Did We Like It?

In our opinion, having an OMRI listing by the USDA for use in organic gardening practices is an essential factor and advantageous. This made us inherently trust the brand, but we decided to test it on our tomatoes to see the results.

Well, we were impressed by its initial response. The easy pour bag is filled with granular, organic fertilizer. Since the bag is resealable, we weren’t worried about the contents getting spoilt over time.

The 2-5-3 ratio of NPK assured us that our tomato plants would thrive – since lesser nitrogen and more phosphorus is ideal. If you have nitrogen-rich soil, then your tomatoes will love the addition of this organic fertilizer.

Coming to the special Jobe Biozome – this is a proprietary microorganism that is innately aggressive. It breaks down the materials, giving faster results in a short period of time. Furthermore, the fertilizer’s granular form makes it easier to spread around the roots of the plants.

What Could’ve Been Better?

Since the product is organic, it has a certain smell that isn’t largely pleasant to humans, but curiosity evoking to pets. In simple words, – you will hate the smell, but your pets might love it. We recommend that you store the product in a safe place where your pets can get in.

Pros
  • Fast-working solution
  • Easy to pour bag
  • Can be used for a long time
  • Completely organic and natural
Cons
  • Has a funky smell
  1. Fox Farm Grow Big Liquid Concentrate Fertilizer

As the name suggests, Fox Farm has developed a fertilizer that helps your tomato plants grow big, lush, and juicy in no time. The formula is concentrated, which means that you’ll have to dilute it before using it. However, the overwhelming results make this extra step worth your time and effort.

Why Did We Like It?

At first, we were a little skeptical about using this liquid fertilizer. Since it only comes in a concentrated formula, we were scared that it might burn the tomato plants’ roots. It is important to properly dilute the formula with adequate water before applying it to the plants.

Well, the results speak for themselves. This fertilizer formula comes in an NPK ratio of 6-4-4. Simply, this means that the proportion of nitrogen is more than phosphorus – which is excellent. This fertilizer is ideal for use in soils that have low nitrogen content.

The amount of liquid fertilizer you need to use is minimal – about two teaspoons per gallon of water. This ensures that the plants’ roots don’t burn and make the product last for a long time.

If you apply this to new plantings, make sure to let them settle in first before using this fertilizer.

What Could’ve Been Better?

Although the product mentions the word ‘organic’ in it, the manufacturer refers to organic growing and not the product itself. So if you were looking for organic fertilizer, this might not be the best option, as it is a synthetic fertilizer.

Pros
  • Need to use very little product
  • Ideal for low nitrogen soils
  • Product is long-lasting
  • Very easy to use
Cons
  • Contains synthetic ingredients
  1. Organic Plant Magic Fertilizer

For our next recommendation, we bring you a completely organic fertilizer for your beautiful tomato garden. This formula works on all types of soil without requiring any additives or additional products. Moreover, since it is organic, it is entirely safe to have around pets and children.

Why Did We Like It?

An organic fertilizer that guarantees to help you produce lush, full blooming, tasty, and vibrant tomatoes sounds promising. We decided to test the product for you and tell you the results.

First things first, this fertilizer is super easy and convenient to use. All you need to do is add water, mix it up well, and use it on the soil. No matter what kind of soil you have, be it loamy, sandy, or clay, this fertilizer has been designed to produce excellent results on all of them.

The fertilizer contains various beneficial macronutrients that can help tomato plants grow taller, healthier, and even enhance its color and flavor. One of the best things about this organic fertilizer is the fact that you can start using it even when your plant is just a seedling.

Many other fertilizers recommend that you wait a few weeks or months before adding them. However, this completely natural and safe fertilizer can be used right from the start.

What Could’ve Been Better?

Like many other organic fertilizers, this product also has a natural odor, which is not entirely pleasant. Many users might find this smell very offensive. We recommend using a light face mask during the time you mix and apply this fertilizer, in case the smell is too unpleasant.

Pros
  • Zipper lock pack to protect contents
  • No synthetic or chemical ingredients
  • Can be used directly or by mixing
  • Doesn’t break down salts in the soil

What Could’ve Been Better?

  • Good for nitrogen-rich soil
  • No harmful chemicals
  • Can make 1,000 gallons of fertilizer

Why Did We Like It?

When we read that this fertilizer has higher amounts of phosphorus, we were slightly skeptical about using it. The 2-3-1 ratio also meant that we had to use more fertilizer compared to other products we have used.

However, on using this fertilizer for our tomato garden, we noticed a significant change in its produce. The tomatoes were more vibrant, fragrant, plump, and juicy. The ingredients used (hydrolized fish and seaweed) produce fantastic results on varieties of plants and flowers.

Coming to the ease of use, this product can be easily mixed by hand. Moreover, you can apply it to your tomato plants with the help of a sprayer, a drip line, or even do it manually if you wish to.

Applying this fertilizer just once in 2 to 3 weeks is enough to produce brilliant results. You may have to use it more often, depending on the results you notice.

What Could’ve Been Better?

Since the fertilizer is made of fish and seaweed, you can imagine the kind of smells it naturally brings with it. Well, for many people, this might be a deal-breaker. The smell is indeed quite strong and can take some getting used to.

Pros
  • Certified organic
  • Can be used around pets and children
  • You can apply it using various easy methods
  • The ingredients are long-lasting
Cons
  • Has a powerful stench

Why Did We Like It?

The first thing we want to mention about this product is that professionals widely use it. This just tells us that they trust this combo kit, and maybe we should too. Of course, we couldn’t just blindly believe the reviews, so we decided to check it out independently.

All the products in this combo kit are entirely water-soluble. This made it super convenient for us to mix and apply to our tomato plants. Moreover, there is a variety of products and ingredients to choose from – according to your plants’ requirements.

Although the ingredients are not nitrogen-rich, there is a high amount of calcium nitrate – which makes up for it. There is also Epsom Salt included in the pack. You can apply this back into the soil to restore the sodium which the soil has lost.

Finally, the product can last for a long time, but the bags are not resealable – so keep this in mind.

What Could’ve Been Better?

As we mentioned, the products are long-lasting, but the bags are not. When you open a bag, you will need to find an appropriate airtight container to store the fertilizer in. Also, the nitrogen content is a little low, so this product is best used in soils that already have a high nitrogen level.

Pros
  • A variety pack for all your plant’s requirements
  • Easy to use
  • Epsom salt included
  • All products in one pack
Cons
  • Non-resealable bags

Tomatoes Fertilizer Buyer’s Guide

Now that we have told you all about our top recommendations, you might have a better idea about your tomatoes’ best fertilizers. But before you go off purchasing a bag, we have a few more things to tell you.

When purchasing the best fertilizer for your tomatoes, there are a few more things you need to keep in mind. Being mindful of these factors will help you make the correct choice. Keep reading to find out a few things you need to consider.

  1. NPK Blend

The Nitrogen, Phosphorus, and Potassium blend is crucial for any plant, especially your tomatoes. All these vital substances can help tomato plants grow larger, healthier, and produce better fruits.

That being said, excess of any substance can do more harm than good. While nitrogen can help plants grow thick, too much of it can cause the plants to bear no fruit.

In the same way, phosphorus is also good for the tomato, but too much can cause issues with the soil, drying it out and making it an unhealthy environment for the plants.

It is important to consider the NPK blend and opt for one which meets the requirements of your tomato garden. This will enhance its growth rather than hinder it.

  1. Ingredients

The kind of ingredients used to create a fertilizer mix matter. Depending on your specific requirements, you might be looking for organic fertilizer or a synthetic one. Both have their distinct benefits.

As you would do with any other product, read the ingredients carefully before purchasing fertilizer. It will help you judge the contents and decide whether they are harmful to your growing tomato plants or not.

  1. Budget

When buying any product, the budget is a crucial factor to consider. We have provided you with a list of fertilizers that come in a variety of prices. Of course, we do not recommend opting for ‘budget buys’ when it comes to fertilizers.

However, there are several combination kits, bulk packs, and affordable options to choose from. You don’t need to invest heavily in any product to have the best, most bountiful produce. In fact, all you need is the right kind of fertilizer to tend to the growing tomato plants’ needs.

  1. Frequency Of Application

You might not consider yourself a full-time gardener and still want to grow some beautiful tomatoes in your garden. This is perfectly acceptable. Of course, when you decide to purchase fertilizer, you need to ensure that it syncs with your schedule.

Certain fertilizers require more watering and maintenance than others. While some fertilizers can be reapplied only once in three months, others require more frequent applications.

It is essential to consider this before you purchase the right fertilizer. If you cannot adhere to a feeding schedule, the fertilizer will be largely wasted on the tomato plants. For any fertilizer application, the feeding schedule is imperative.

If you don’t have the time or cannot put too much effort into this process, consider opting for a fertilizer that needs less frequent reapplications. However, if you can manage a strict feeding schedule, opt for other products that you can reapply every two weeks or so.

Overall, we decided that Miracle-Gro Shake’ n Feed is the most convenient, affordable, and long-lasting fertilizer for tomatoes. We also liked Jobe’s Tomato Fertilizer Spikes because of its easy use.

Finally, for those who don’t shy away from non-plant based products, Neptune’s Harvest Organic Hydrolized Fish & Seaweed Fertilizer is the ideal option. Of course, it depends on whether you can get over the smell or not!

We wish you all the best with your tomato plants and hope they grow large and healthy. Until next time!
