Sweet Success: Enhancing Strawberry Yields with Organic Strawberry Fertilizer


There is always a bother to decision for fertilization of strawberry crops in both home gardens and famous commercial farms. Of course, organic strawberry fertilizer is a winner that generates good growth, nutrient and output for the plant and facilitate the eco-friendly agriculture. Organic fertilizer is in favor of the recycling capacity that improves the soil condition and increase the organic matter in the earth through organic substance or items.

Using organic fertilizer for strawberries is highly beneficial in many ways. Since it releases the nutrients in a slow and steady way, the plants are supplied with nutrients consistently and without the risk of chemical burn that can occur using synthetic fertilizers. As Emily Foster, Ph D, an authority on organic horticulture, writes on the University of California Agriculture and Natural Resources website: Organic fertilizers supply organic matter and nutrients to the soil.

This helps with the soil’s structure and build of beneficial microbial life. This soil environment provides value for the strawberry plants in the present and, over the long term, improves soil fertility for the plants to have a healthier soil system to thrive in and promote good yields.

Following an organic approach is also the most sustainable. It has a lower footprint, with reduced fertilizer run-eff from intensively-farmed fields, and helps to conserve a diversity of local life. Most of all, an organic focus fosters a robust garden that supports pollinators, predators and other key beneficial organisms. Attention to fertilizer follows a golden rule of kitchen gardens: what goes in, goes right around, contributing to the sustainability of the garden now and in the future.

We aim to provide in this guide an overview to: the nutritional requirements of strawberry plants; select the right organic fertilizer for strawberries; how to apply it; and an assessment of the difference in quality and quantity of the outcome when organically grown in general. We hope that this approach to strawberries will help gardeners/farmers find sweet success in strawberry cultivation.

Nutritional Needs of Strawberry Plants

Strawberries are sensitive plants that need a healthy diet of nutrients for healthy development, high yields and to help them fight diseases over the growing season. In this article we describe the key elements required by strawberries and what you should look for when selecting your organic strawberry fertilizer.

Strawberries also require a lot of N-P-K, which is short for nitrogen, phosphorus and potassium. Nitrogen is required for the development of leaves and vegation, phosphorus for robust roots and flowering, and potassium improves fruit quality and the overall vitality of the plant. Strawberries need other micronutrients such as calcium, magnesium, and sulphur, which help in plant metabolism and in disease resistance.

Helen Thompson, an expert on berry crop nutrition, points out that ‘organic fertilizers are particularly well-matched to strawberries in that they supply these key nutrients in a slow-release form and in amounts that are well-matched to the plant’s ability to take them up, which is crucial to avoid risk of ‘burn’ through conventional fertilisation with synthetic fertilisers, as well as avoiding loss via leaching’.

Organic strawberry fertilizer often contains bone meal, which is high in phosphorus; blood meal, a very high-nitrogen material; and greensand or potassium sulfate, both excellent potassium sources. In addition to feeding the plant, these organic ingredients increase the organic matter of the soil, which builds up the structure and ability to hold moisture.

From an organic perspective, to provide the strawberry plants with nutrients in a way that supports the underlying ecology of the garden site, the gardener can grow abundant, healthy crops that flourish with strong growth and high fruit yields. We consume for taste and nutrition, as well as a sense of environmental responsibility It is the plants that benefit directly because the lack of powerful chemicals means that the soil life will more naturally invigorate and provide for the crop.

There are wider benefits, too. The fertile, grounded­ reasonableness of organic thinking adds value to what may otherwise be a merely functional task. We consume for taste and nutrition, as well as for a sense of environmental responsibility. These values are important, es­pe­cially at this critical time for the planet.

Choosing the Right Organic Strawberry Fertilizer

When it comes to growing organic strawberries, most farmers these days are using organic methods for fertilizer, as it has become a trend because it does not negatively impact the strawberry plants or the environment and it’s actually more beneficial than chemical fertilizers. Every fertilizer does not produce similar results in natural living things and for plants, selecting the best organic fertilizer from among the various brands is significant. Some of the important key factors to consider before deciding on which fertilizer to use include:

  • Plant growing period
  • Soil types
  • Maturity dates of cultivations

Selecting the best product for the plant is one of the essential factors to increase strawberry production. However, it seems obvious that farmers should pay attention to the mentioned factors above, to obtain excellent quality produce.

Factors to Consider

  • Nutrient Balance: Look for a fertilizer that provides the right balance of nitrogen (N), phosphorus (P), and potassium (K). These nutrients are important for strawberry growth, and each one plays a different role. They also need to be in the right ratio to each other. Too little of one could affect the plant’s health and crop yield.
  • Soil Type: Where you live can determine what type of soil you have (local extension agencies can help out with a soil test), and where it is the most absorbent and retainants of elements (sandy soils, for example, will typically require more frequent fertilization as they are prone to leaching nutrients).
  • Organic Certification: You should also know about the certification given by famous organic organizations on this product. This is the strongest assurance that you get about the product being organic. It helps you confirm that there’s no synthetic additive in the fertilizer and that the process of manufacturing also falls in line with the standards of organic farming.

Recommended Organic Fertilizers

  • Fish Emulsion: Contains lots of nitrogen, so it encourages good leaf growth and strawberry plant vitality. Works best in a plant’s early stages of development.
  • Bone Meal: High in phosphorus and beneficial to root development, this should be incorporated into the garden during planting, and is critical to flowering and fruit-production.
  • Kelp Meal: Organic kelp meal, a good source of potassium and trace minerals, helps fruit quality and assists the plant in resisting stress.

Susan Mitchell, PhD, a specialist in organic crop fertilization, advises: “When selecting an organic fertilizer for strawberries, it may also be beneficial to look at products that contain an array of micronutrients such as iron, manganese, and zinc, which can help with the overall full-flavored growing and disease resistance attributes that discerning buyers seek.

Product Recommendations

Those who want specific product recommendations will find that Down to Earth has a Strawberry Fertilizer Mix that delivers a balanced N-P-K fertilizer in ratios that will please every vitamin-pill freak. It also includes beneficial mycorrhizae, like those boosters designed for ‘plant health and fruitful production’.

Giving strawberries the right kind of organic fertilizer not only ensures that they’re getting the right nutrients to grow them and make them plump and healthy, but it also affects if and when they have a desirable taste. For both the gardener and the farmer wanting to earn money from this fruit, making the right choice can be a matter of success or failure.

Application Guidelines for Organic Strawberry Fertilizer

A correct application of organic strawberry fertilizer would ensure that it can reach the desired effects as a whole, to improve the health of strawberry’s plant as well as its fertilizer sometimes also depend on the best farm practice.

Best Practices for Applying Fertilizer

  • Timing:
    • Initial: The application preferably at the beginning before planting is used for pre-plant soil preparation.
    • Subsequent: The application may be staggered to be in line with the standard crop’s important growth events. Apply early at the beginning of spring when plants start producing new leaves and again after the first harvesting to promote new vigor and a second fruiting (if possible).
  • Method: Apply the fertilizer at the base of the plant so that it will not burn the leaves or stems. It can then be spread around the soil surface, which widens the area available for the roots to take up the nutrients. Incorporating the fertilizer into the top several inches of the soil reduces the risk of nutrient runoff and puts the nutrients within reach of the plant’s roots.

Adjusting Application Rates and Schedules

  • Soil Fertility Levels: Regular soil tests should be obtained to determine existing levels of nutrients. This will also determine the best way to add additional fertilizers, if any. Over-fertilizing can result in over-leaching, which contributes to nutrient runoff and creates more problems for the environment, while under-fertilizing results in plant starvation.
  • Plant Growth Observations: Through the season, check your plant growth. If you see signs of a nutrient shortage (such as lower-leaf colors fading to yellow or, in a small plant, the growing tip becoming longer and thinner), reduce the fertilizer dose to half strength for a week or two. If you see a sign of nutrient overdose (for example, really lush growth but no large display of flowers or fruit), cut back somewhat.

Expert Advice

“Each strawberry patch is different, what works on one patch might not work on the next,” said Susan M Mitchell, an organic crop expert with the Northeastern Integrated Pest Management Centre in Amherst, Massachusetts. “You really have to develop an informed, individualized fertilizer management plan or program for each patch: testing your soil regularly, gardening with your eyes wide open, and watching closely and applying fertilizers in small amounts as required by your plants.”

These are the guidelines for using organic strawberry fertilizers to give your strawberry plants the nutrients and water they need at exactly the right time to grow rapidly and produce fruit. If you arm yourself with this knowledge, you will be ready to build a lush, highly productive strawberry bed.

Monitoring and Adjusting Fertilization Practices

If you want organic strawberry fertilizer to really work, if you want your strawberry plants to grow the healthiest that they possibly can, then your fertilizing needs to be adjusted and continually evaluated. You fertilize, you watch how it works, and then you adjust. Take into account the environmental conditions, take into account your plants, what they need, and how they respond to your organic fertilizer.

Techniques for Assessing the Effectiveness of Fertilization

  • Soil Testing: Soil nutrient testing is a critical part of the strawberry growing regime. The report from the lab indicates whether these nutrients are in balance with your strawberries’ needs. Evaluate the report and decide if additional fertilizer needs to be added or if the nutrient level needs to be reduced.
  • Plant Health Monitoring: The physical appearance of your strawberries provides vital clues for nutrient management. Nutrient deficiencies cause leaf discoloration, poor fruit set, or stunted growth. Nutrient excesses often show up as leaves with a burnt appearance. Ongoing field observation ensures that managers spot these issues early and can monitor the efficacy of their current fertilizer strategy.

Adjusting Fertilization Strategies

  • Environmental Factors: Either a period of rainfall or drought for an extended period can affect how much nutrition is available in the environment, and how much nutrition plants need at given times. With a clear view of how weather patterns are impacting a farm’s strawberry growth, fertilization schedules can be adjusted accordingly.
  • Plant Response: In response to plant response, you would vary the amount and/or composition of fertilizer depending on how the plants appeared. For example, if plants showed signs of nitrogen deficiency (e.g., yellowing of older leaves) then provide some extra nitrogen in your next fertilizer addition.

To finalize the adjustments, dedicated persons might want to seek the advice of agricultural extension services or crop specialists, recommends Mitchell. “Let the plants guide your fertilization decisions and work with experts to create a dynamic fertilization plan that adapts when the plants need it,” she concludes.

But with a sensor that is checking your strawberries’ fertilization constantly and calibrating it down to the milliliter, you are better able to give your plants exactly what they need and no more. This ultimately leads to better, healthier crops and also more sustainable agriculture because you are not wasting fertilizer or damaging the environment with overfertilization.


To summarise the road to sweet success with organic strawberry fertilizer, attention to detail is of paramount importance throughout, from the selection of the right fertilizer to the application of fertiliser and the ongoing adjustments to the fertilization strategy based on the performance of strawberry plants.

By using the organic strawberry fertilizer, the organic nutrients can be delivered directly to the strawberry plant making sure that the strawberry plants get the nutrients they need to live and grow healthily, which helps strawberry produces more fruits.

Moreover, some other specific advantages for organic fertilizer could be obtained is that growing fruits and veggies organically could help to reduce the so-called “ecological footprint” of agriculture by reducing the amount of chemical runoff into the environment, allowing the soil to remain intact and preserve its natural structure, which encourages biodiversity.

Overall, lots of benefits could be obtained from using organ fertilizers for agricultural activities and with reductions in chemical runoff, soils kept intact, and encouragement of biodiversity, it’s a more sustainable way of farming.

As the plant physiologist Susan Mitchell says: ‘By observing and responding quickly to the needs of what’s happening with the plants right now … growers can help to maximise the availability of the organic fertilizers they are using, and grow in ways that benefit the environment as well as produce healthy food’. Not only does this approach make the strawberries grow better, but the growing practices are more environmentally sound.

Using organic strawberry fertilizer and the techniques discussed above can significantly improve the way strawberries are grown. Whether at home in your personal strawberry garden or on larger acreage with commercial goals, the success of your fertilisation by both humans and mycorrhizae is cook-book style. Use these recipes and underserved strawberries, with their improved flavour and aroma, will find their way to your table.
