Are you worried about stunted growth and low yielding of tomatoes? To overcome these problems we built this guide in which you will get to know the best fertilizer for tomatoes.
As tomatoes are nutrients loving plants so the timely fertilization of proper nutrients is the necessary part to get the boosted growth with more yield.
In this guide, we are going to tell you the ground knowledge to grow the tomatoes, fertilizers, and caring tips.
In short, by following this guide your tomatoes will thrive at their maximum potential yielding more and more.
So, let’s get started.
What Is the Best Fertilizer for Tomatoes?
Tomatoes are a well known heavy feeder annual plant. It shows that they need more nutrients to meet their requirements for proper growth. So, if you want to maximize the outcome from the plant then you will need to give more than what is already present in the soil.
The fertilizer for tomatoes could either be organic or chemical in nature but the main purpose is to improve nutrient availability at the root zone of tomatoes.
But before choosing the fertilizer for the tomatoes, knowing the current status of the soil nutrient content is necessary. This soil fertility status can be known by doing soil testing with soil testing kits.
If the soil nutrient status is already good enough to support the tomatoes, then any balanced fertilizer should be used.
But one thing to keep in mind whenever buying the tomatoes fertilizer that never chooses the high nitrogenous fertilizer otherwise it will result in lush green tomatoes and low in yield.
The other problem that can be often seen in tomatoes is the sickly tomato plants that result from phosphorus deficiency. If any of the above two symptoms appear, then go for the high phosphatic fertilizer.
Buying Guide: How to Choose The Best Fertilizer for Tomatoes
The most troublesome step in fertilizing tomatoes is choosing the right fertilizer. So, we built this guide to ease the reader in choosing the best fertilizer for tomatoes. By following these 3 simple steps this journey of choosing the fertilizer would become easy.
Step 1. Check the Condition of the Soil
The very first step in fertilizing tomatoes is to know the current status of your soil. It includes the soil condition, its nutrient status, and soil pH.
The type of fertilizer for tomatoes does completely depend on the type of soil. As each type of soil has some unique number of nutrients in it and this proportion can be known just by soil testing.
For testing soil, two popular options including home testing kits that are DIY and other ones are soil testing kits available in the market.
The level of nutrients composition in the soil can be measured by comparing it with the chart given with the testing kits.
Most of the soil does have a high amount of basic nutrients like nitrogen and magnesium so there will be no advantage of applying the nitrogenous fertilizers on the growth of tomatoes.
So, after testing, if the nitrogen and magnesium is already in enough amount in the soil then you just need to find the high phosphatic fertilizers
Step 2. Check the Growing Stage of the Tomato Plants
During the growth of tomato plants, it needs various nutrients at different growth cycles. If the plants do start sprouting of leaves or a new seedling stage then the application of phosphorus fertilizer will be good.
The best phosphatic fertilizers in the market are available in the form of Miracle-Gro and JR Peters. The application of these fertilizers will help the building of a strong root system.
If the plants are in the developing stage or established then go for the potassic fertilizer like Dr. Earth and Urban Farm, which will help the healthy growth and high yielding plants.
Nitrogen is also an important nutrient during foliage growth but too much nitrogen will lead the plants to more foliage and less yield.
Step 3. Choose the Right Fertilizer
After soil testing, once you know the soil nutrient status then it will be easy to decide the fertilizer. As if the nitrogen is already present in soil then go for the fertilizers that have a high amount of phosphorus.
Consider using the fertilizers containing 5-10-5 or 5-10-10 NPK if the nitrogen is required less.
In case the soil testing result shows the low nitrogen in the soil then the application of the balanced fertilizers like 8-8-8 or 10-10-10 and 15-15-15 will be beneficial for the plant growth.
What if you don’t have a soil testing kit?
If the soil testing is not available at tomato gardens then assume the nutrient status of the soil as balanced soil and go for the fertilizers that are rich in phosphorus.
Role of Macro and Micro Nutrients in tomatoes growth
A soil rich in macro and micronutrients does support the plant growth and helps the build-up of a strong root structure that ultimately supports the vegetative growth of plants.
If the plants are provided with all types of nutrients then it will result in the form of nutrient-rich and fully ripened red tomatoes with the bountiful harvest.
The Macronutrients ratio in any fertilizer package is mostly displayed in the form of NPK as 10-10-10 or any number. This number shows the percentage of that nutrients in that plant food.
All of the macronutrients do have their vital role in plants growth as:
- Nitrogen stimulates the plant’s vegetative growth as foliage and helps the plant to boost up the growth of stems and leaves.
- Phosphorus helps in establishing the strong roots network and development of blossoms, vegetables, and fruits.
- Potassium has a role in developing the sturdy root systems for the better take up of the nutrients from the soil.
Most of the vegetable fertilizers do have some composition of the micronutrients that have equal importance in the growth of the plants and fruits as macronutrients. The beneficial effect of these micronutrients is such as:
Calcium nutrient helps the plants to keep them safe from diseases like blossom end rot and some other harmful substances. It helps to create a balanced soil environment for the plants.
The sulfur nutrient helps in the buildup of the plant structure and overall development. Magnesium has a keen role in the photosynthetic activity of the plants.
