Buying the Best Fertilizer for Strawberries – Buying Guide

You’ll find many fertilizers in the market, yet choosing the best out of many options is not as easy as you think. If you want to grow healthy strawberries and other berries in your yard, here’s a guide to consider before spending your money on your preferred brand. 

Know What Type of Strawberry Plant to Consider

You’ll encounter different strawberry plants, and before you start cultivating, you should know which is the best type to grow. 


This type has a batch twice a year. You’ll be able to harvest at the start of the year, while the second batch will be in early fall. However, the sizes of the fruits from this plant-type are smaller compared to June bearers. 

In using fertilizers, it’s typically after your harvesting period. It’s very important not to over-fertilize because it might make your berries larger, which is not ideal for this type of strawberry plant. 


This strawberry plant is the most popular type because big farmers tend to grow it for commercial purposes. You can expect more yield in two weeks to three weeks, which is ideal for start-up agribusinesses. 

This type produces a single fruit yearly during June, and you’ll see a lot of seedlings for this variety in many stores around you. 

When it comes to its fertilization, it’s also after the last harvest, in preparation for the succeeding year. 


This strawberry plant-type is typically for indoor farming. There’s a lesser yield compared to the first two varieties, and the size is even smaller. On the bright side, this variety is beneficial because you can harvest a fruit daily or an interval of every two days. 

The fertilization is typically from June to August. 

Determine How Many Strawberry Plants You Need for Planting

Once you determine the type of strawberry plant you need, the next thing you need to consider is how many plants you need. 

You need 6 to 7 plants if you want to produce enough berries for an individual plant. However, these require care and proper plantation-management. If you’re growing for 5 to 6 people, you need about 30 to 35 plants to produce enough fruits. If you need to produce more people, you’ll need more plants. 

Some farmers are starting to make jams for their families or business, leading them to preserve strawberries. You’ll need to boost the number of plants if you want to add jams to your list for selling. 

Choosing What Fertilizer-Type to Use for Your Plant

The next thing on the list is choosing a suitable fertilizer-type. Here are the typical ones you’ll find in the market.

Powdered Fertilizers

This type is not very typical to most fertilizers, but it’s more effective than the liquid-type because the highest concentration works better. These have a longer shelf life, and it’s also cost-efficient, which makes it favorable if you’re sticking to your budget. Plus, you can control the amount you put in your soil for effective cultivation. 

Granular Fertilizers

This type is an excellent alternative for powdered fertilizers, and most stores offer this type, making it easier for you to get supplies. It also works the same as powdered, where you mix it into your yard’s soil. It’s important to mix it well so it will not overwhelm the roots of your plants. 

In applying this type of fertilizer, you can fix it in your water. 

Liquid Fertilizers

This fertilizer-type needs control as per the instructions on the packaging. The concentration is too strong that any excessive application may lead to burning your plants’ leaves. The best thing about this fertilizer-type is that you can save time by applying it through electric sprayers. 

Consider the Fertilizer’s Formulation

You’d notice that some fertilizers indicate a formulation label, which are the three numbers on the packaging label. The formulation varies on the nutrient content of the product. If you’re not familiar with how to read the label, here’s a quick guide for you. 

If you see a label stating “3-2-4,” it’s the amount of nitrogen, phosphorus, and potassium, respectively, in the product’s ingredients. It means, 3% nitrogen, 2% phosphorus, and 4% potassium. 

If you’re curious to know how you can calculate the total amount in a bag, you need to multiply the percentage by the product’s content-weight. In a 4-pound bag with a 3-2-4 formula, there’s 0.12 nitrogen, 0.08 phosphorus, and 0.16 potassium. 

Why Fertilizers Should Be an Option for Planting Strawberries

You can plant something using soil solely, yet those who use fertilizers enjoy better results. Many farmers consider using fertilizers because of the benefits it provides, such as the following:

Fertilizers provide a multi-nutrition composition to the plants.

With the help of fertilizers, these can enhance your harvests’ quality, raising the utilization ratio. 

Fertilizers provide a slow release.

Since absorption is short and limited, using fertilizers will delay nutrient-release to let plants absorb nutrients effectively. With the slow nutrient-release, your soil will reduce nutrient-loss. 

Fertilizers boost production.

The best effect of fertilizers on plants is how it can produce added yield, which is favorable to businesses. There should be control when applying fertilizers because anything excessive might lead to negative side effects. 

Fertilizers can improve your soil’s health.

If you want to produce healthy plants, your soil should be in exceptional condition. Fertilizers can enhance your soil’s chemical and physical properties for enhanced development and absorption. Most use organic ingredients, which are excellent for your soil’s health, while others include additional nutrients. 

Some Tips in Using Fertilizers on Strawberry Plants

Most farmers would prefer an exceptional yield, and to make it possible, you should make sure that the nutrients are available to the roots of your strawberry plant. The tip is to apply fertilizers at different times during the year. 

It’s best to use fertilizers before planting because these ready the nutrients before transplanting to your soil. However, the fertilization time depends on the type you’re using since every type comes with a particular reproductive and vegetative state.

Another thing to keep in mind is that you’ll need loamy soil in growing strawberries. This type of soil will make the roots absorb the nutrients before these will leach down. 

Some Thing to Keep in Mind Before Using Fertilizers

Strawberries are robust, and these can grow in various settings. If you know how to use fertilizers properly, it will result in a generous harvest. However, there are some things you need to keep in mind.

You should plant strawberries in a place that receives about 6 hours of full sun. These plants prefer fertile soil with a lot of organic content. 

After setting up a place where you can grow your strawberries, regularly watering these is a must. These plants are not a fan of wet soil, yet these also don’t want a drought one. Consistency is important when it comes to growing strawberries. 

Make sure that the place where you planted your strawberries are away from weeds. There shouldn’t be any pest or keep it from diseases too. One tip you can consider is to put a layer of mulch under your plants’ leaves. Plus, you should remove decaying foliage once you see it. 

It’s best not to plant your strawberries where you previously planted potatoes, peppers, raspberries, eggplant, and tomatoes. There might be a threat of Insects from these crops, which can affect your strawberries’ growth. 

How to Plant Strawberries: Steps for Beginners

Here are steps you can consider in planting strawberries:

  1. Plant these once the ground is ready during spring. 
  2. Make sure the space of your plants is at least 20 inches apart. 
  3. When it comes to holes, dig deep ones, and make sure these are wide enough to put up your plant’s whole root system. 
  4. Plant your plant’s crown at soil level with firm soil around it. 
  5. Add fertilizer to the bed to boost the growth of your strawberries.

Tips on How to Protect Your Strawberry Plants

Keeping your strawberries from birds or bugs is easy because you’ll only need to cover your plants with a bird netting. There are also other ways to protect your strawberries, like the following:


It’s one of the simplest ways to protect your strawberries. All you need is to cover your rows with a layer of straw mulch during the winter. Make sure your wheat, oat, or rye straw is clean. Plus, the best time is when the temperature drops to 20 degrees Fahrenheit. 

Pest Control

Birds like grackles, crows, robins, and house finches love eating strawberries. Dealing with this is by making scarecrows or considering noisemakers. When it comes to insects, like crickets, sap beetles, whiteflies, cutworms, flower thrips, and cyclamen mites, it’s best to consult with a local extension agent for treatments. Unlike birds, bugs are more difficult to handle. 

Overwintering Strawberries

This way is applicable if your plant bears strawberries in early summer. June bearers will only require winter care to turn up its production by the succeeding year. This method will let you renovate your plants by cutting it to 2 inches high. It will prevent insects and diseases from using the plants as their home.

FAQs (Frequently Asked Questions) 

I see some fertilizers that are suitable for hydroponics. What is it about?

Hydroponics gardening doesn’t use any soil. It grows through water and nutrients. You can set up a system for your strawberries for quicker growth and more yield. Most growers use this system when they don’t’ have an available gardening plot. 

What planting systems should I use in growing strawberries?

The system depends on the variety you’re planting. June bearers use a matted row system. If you’re planting ever-bearers or day-neutral strawberries, these are better with the hill system or mounding system. Regardless of any system, both provide quality crops. 

Aside from the two, you can also consider double hedgerow systems, single hedgerow systems, and spaced row systems. 

Will winter destroy my strawberry plants?

It might destroy your plants. Cold weather affects the vegetative part of the plant, which will wilt it until it dies. If your strawberries are about to ripen, you can wait and let these ripen before picking it up. However, don’t want hard frost to compromise your crops if you don’t want to eat squishy ones.
