Fertilizing Your Beefsteak Tomato Plant:
The Dos and Don’ts

Updated: May 19, 2023

Tomatoes are the most popular vegetable in home gardens, and beefsteak tomatoes are one of the most sought-after varieties. But growing beefsteak tomatoes can be challenging, especially when it comes to fertilizing. Fertilizer is essential for beefsteak tomatoes to grow healthy and produce a good yield. However, too much or too little fertilizer can cause problems, such as stunted growth, blossom drop, or poor fruit quality. In this article, we will discuss the dos and don’ts of fertilizing your beefsteak tomato plant.

Dos of Fertilizing Beefsteak Tomato Plants

Do Test Your Soil

Before you start fertilizing your beefsteak tomato plant, it’s essential to test your soil’s pH level and nutrient content. Tomatoes grow best in slightly acidic soil with a pH level between 6.0 and 7.0. A soil test will also reveal any nutrient deficiencies or excesses that your plants may have.

Do Use Organic Fertilizers

Organic fertilizers are a good choice for beefsteak tomato plants because they release nutrients slowly over time and improve soil health. Compost, manure, bone meal, and fish emulsion are excellent sources of organic nutrients for tomatoes. You can also use organic fertilizers that combine several nutrients, such as blood meal, feather meal, and kelp meal.

Do Fertilize Regularly

Beefsteak tomato plants need a steady supply of nutrients throughout the growing season to support their growth and fruit production. Therefore, you should fertilize them regularly, starting from the planting stage until the end of the season. It’s best to follow the fertilizer’s instructions regarding the frequency and amount of application.

Do Water Your Plants After Fertilizing

After applying fertilizer to your beefsteak tomato plant, you should water it well to help the nutrients penetrate the soil and reach the roots. Watering also prevents the fertilizer from burning the plant’s leaves or stem.

Don’ts of Fertilizing Beefsteak Tomato Plants

Don’t Over-Fertilize

Over-fertilizing your beefsteak tomato plant can cause more harm than good. Too much fertilizer can burn the plant’s roots, damage its foliage, or reduce fruit quality. Moreover, excess nitrogen can lead to lush vegetative growth at the expense of fruit set. Therefore, it’s crucial to follow the recommended dosage and apply fertilizer sparingly.

Don’t Apply Fertilizer Near The Stem

Applying fertilizer too close to the stem of your beefsteak tomato plant can cause damage to its roots or stem. It’s best to spread the fertilizer evenly around the plant’s drip line (the outer edge of its canopy). This way, the nutrients will be available to all parts of the plant without causing any harm.

Don’t Use High-Phosphorus Fertilizers Too Early

Phosphorus is an essential nutrient for beefsteak tomato plants’ root development and fruit production. However, using high-phosphorus fertilizers too early in the season can lead to excessive vegetative growth at the expense of root growth. Therefore, it’s best to use a balanced fertilizer (with equal amounts of nitrogen, phosphorus, and potassium) during the first few weeks after transplanting.

Don’t Fertilize During Hot Weather

Fertilizing your beefsteak tomato plant during hot weather can cause water stress on its roots and increase its susceptibility to diseases like blossom-end rot. It’s best to avoid fertilizing during heatwaves or drought conditions and water your plants regularly instead.

FAQs About Fertilizing Beefsteak Tomato Plants

Q1: How often should I fertilize my beefsteak tomato plant?

A: You should fertilize your beefsteak tomato plant every two to three weeks during the growing season.

Q2: Can I use chemical fertilizers on my beefsteak tomato plant?

A: Yes, you can use chemical fertilizers on your beefsteak tomato plant if you follow the instructions carefully and avoid over-fertilization.

Q3: How much fertilizer should I apply per plant?

A: The amount of fertilizer you should apply per plant depends on its size and age. Generally, you can use about one tablespoon of granular fertilizer or one gallon of liquid fertilizer per foot of plant height.

Q4: Can I use compost as a sole source of nutrients for my beefsteak tomato plant?

A: No, compost alone may not provide all the necessary nutrients for your beefsteak tomato plant. However, you can use compost as a supplement to other organic or chemical fertilizers.

In conclusion, fertilizing your beefsteak tomato plant requires careful attention to dos and don’ts. Testing your soil, using organic fertilizers, regular application, watering after fertilization are some dos that will promote healthy growth in your plants. Meanwhile over-fertilization, high-phosphorous application too early in the season or during hot weather are some don’ts that should be avoided at all costs to prevent damage or poor fruit quality in your plants.
