How To Select a Fertilizer for Strawberries

how to select a fertilizer for growing strawberries

The selection of proper fertilizer for your plants is a quite worthy step because the right fertilizer ensures a good yield. Choosing fertilizer’s kind depends on two factors i.e age of plants and time of year.

The soil should be treated with some kind of organic material having an equal proportion of nitrogen, phosphorus, and potassium before the plantation. The soil treatment should be done at least in the upper 6 inches of soil to ensure the nutrient’s availability.

During the first year, you have to do some extra job to keep an eye on your plants to note that if berries are not ripening then add a little nitrogen to get better results. 

Add a little amount of ammonium nitrate fertilizer at the end of summer to the plants to keep them safe from cooler months.

Add another round of fertilizer to your plants during the following year to support their growth throughout the growing season.

You should do the testing of the soil of your garden to know the current nutrient status. If the nitrogen contents are high then there are chances that you will get busy berries plants.

The kind of fertilizer you are using is also a great concern here because the granular and liquid fertilizer has its own pros and cons.

  • Granular fertilizer is easy to apply and more precise than liquid fertilizers. You just need to broadcast them to the soil near the plant’s roots. After the application, water the soil quickly and properly to get effective results.
  • Liquid fertilizers are sprayed directly on the plants. Some liquid fertilizers are available in concentrated form so you have to dilute them for application. But you don’t need to water the plants after application.

If you are using liquid fertilizer then you should dilute the solution properly otherwise the concentrated solution will burn the plant leaves.

The watering of berries plants is quite worthy of things to keep them alive because they don’t like wet soil all the time. So, you need to water them regularly according to soil moisture status.

You need to make sure that there are no weeds growing along with strawberries. Also, keep an eye open to note that if there are any pest or pathogen attacks that happen.

The soil-borne pathogen attack can be minimized by covering the soil with straw mulch which will retard the entering of any pathogen host. If any sign is found just remove the mulch material.

How Many Strawberry Plants Do You Need?

how many strawberry plants do you need to produce a good yield?

It is generally believed that 6-7 plants can produce enough strawberries for an individual if you manage their plantation, care, and care accordingly. If a family has a 5-6 person then you need to procure at least 30 to 35 plants. That will produce enough fresh fruits for a single family.

If you want to preserve the strawberry for jam or other purposes then you can increase plant number.

How to Fertilize Strawberry Plants?

Nitrogen is needed for strawberry plants in a huge amount at two times in its growing period i.e in early spring and then in late fall. Because they start to produce berries in these months.

If you prepare the soil well with manure and organic then your plants will need less amount of fertilizer in the future.

The basic amount of nutrients needed by strawberries is 10-10-10 proportion and if growing organically then this number may vary.

If you are doing 10-10-10 fertilizer then you should apply 1 pound of fertilizer per 20 strawberries just after one month of the plantation.

If the berries are more than one year old then fertilize them once a year after fruit harvest.

Try not to add the fertilizer to June bearers in early spring, it will soften your fruits and increase the risk of an attack of diseases.

In either case, try to mix the fertilizer in the soil thoroughly and properly irrigate it.

And if you are doing organic farming then add the aged manure as a nutrient source. Because fresh manure can be a source of termites. 

Other organic foods for strawberries are fish meal, alfalfa meal soy meal, and blood meal. All of these meals increase the soil nitrogen level.


Fertilizers of granular from being applied to the soil by the broadcast method and then mix them completely into the soil.

The mixing should be finely done so that the plant’s roots easily get access to the nutrients.

The solution concentration should be according to the directions otherwise it will burn the leaves of the plant. The main benefit of liquid fertilizer is time-saving because you can apply the fertilizer with the help of garden electric sprayers easily in a little time.

When to Fertilize Strawberry Plants?

when to fertilize a strawberry plant

If you want to get a good yield from your plants then you should keep nutrients available to the plant roots always. To attain this you have to fertilize the soil at different times in a year.

Strawberry plants love to grow in loamy soil. If the soil type of your garden is clayey then add some sand into it, because the right soil will keep the nutrients available to plant roots all the time otherwise the nutrients will leach down.

Fertilization should be done before the plantation so that the plant gets readily available nutrients the second it is transplanted to the soil.

The fertilization time varies from type to type, as each type has its own vegetative and reproductive stage which is briefly discussed in the types of strawberry plants section.

Types of strawberry plants according to fruiting time

Before plantation, you should decide the type of strawberry because every type has its own fruiting time and fruit quality. These are the types:


june berring strawberry plant

This is the most popular variety as commercially grown by big farmers. They produce a huge amount of fruits in the two to three weeks duration.

It produces one fruit per year in the month of June. It is the same variety which you mostly buy from the stores.

The fertilization of these plants is done after the last harvest to prepare for next year.


ever-bearers strawberry plant

These types produce the fruitings two times per year, at the beginning of the year and then in early fall. The fruit size is smaller than June bearers.

Fertilization of these types of plants is done after the harvesting. Here the care is needed to be taken to not over-fertilize the plants to get the larger size berries. Because this will harm your plants.


day neutral strawberry plant

It is typically a variety of indoor growing plants. It produces very much less yield than June bearers and of small size. 

The only benefit of this variety is that you can get a handful of fruit daily or two days intervals.

The fertilization is done in the months of June, July, and August.


Choosing the best fertilizer for the strawberries has not always been easy work. The right fertilizer will enhance the plant’s health and help to produce delicious fruits. 

You should know the present soil status where strawberries are growing while deciding the fertilizer because every fertilizer has its own merits.

Some are easier to apply but some work great. Some need mixing to soil but some are sprayed.

The right fertilizer at the right time will obviously support the growth of plants and produce a huge load of berry fruits. So when you are deciding the best fertilizer for strawberries keep these things in mind.
