Best Fertilizers For Tomatoes At Different Stages

We gardeners love growing tomatoes, and there are so many tips to care for them. What we are going to discuss today are the details of how to fertilize tomatoes from seeds at different stages. You will find plenty of tips and tricks below, and growing tomatoes will be easier. I also include some options of the best fertilizers for tomatoes at different stages as well. There are so many things to know, so feel free to check them out.

How To Grow Tomatoes From Seeds

Generally, there are two main ways to grow tomatoes: from seeds and by picking up starting tomato plants from the nursery. The former is way easier than the latter, and we are only going to talk about growing tomatoes from seeds today. Below are how growing this type of delicious produce works:

Step 1: Selecting Tomato Seeds

Before you grow tomatoes, you have to choose the type of tomato that you want to have in your garden. There are a few different types of seeds that you should have in mind which are:

  • Heirloom Seeds: An heirloom is a tomato that has been handed down through the generations that is an open-pollinated variety. One of the main reasons to grow an heirloom is its flavor, so rich and so tasty. More than that, this type also provides a wide variety of colors, shapes, and sizes for you to choose from. Some of the best heirloom varieties are Big Rainbow, Brandywine, Cherokee Purple, and Pineapple.
  • Hybrid Seeds: Plant breeders create hybrid seeds by crossing between the pollen from two different kinds or species. The thing is that hybrid seeds cannot be kept because they don’t produce plants that are true to type. One of the main reasons that hybrid seeds are popular is the improved features that they have. Hybrid seeds provide better standard yields, and they are disease-resistant and vigor. Sun Gold is one of the popular varieties, and these tomatoes are cherry-sized with a golden color.

Step 2: Starting Tomato Seeds

After you selected your tomato seeds, it is time to start them. You have to know when to start the seeds in order to receive the finest yield possible. The best time to plant them is a few weeks after the last frost date. This is why you should always do your research on the final frost date before starting your tomato seeds.

When you sow, do it in a group of two or three seeds per hole. After 7 to 10 days, your tomato seeds will begin to germinate. To ensure proper germination, make sure that the temperature is between 65 to 85 degrees Fahrenheit. The best conditions to promote tomato seeds to healthily germinate and grow are good air, high humidity, and warm soil.

Step 3: Tomato Seeds Care

The germination process is over once the primary root is formed, and this next phase is called sprouting. You will see the branch develops upward from the seed, and that is when you need to care for them. In this stage, there are a few important things that you want to provide for your tomatoes.

  • Fertilizer: Many people go for pre-planting composting by using additives and fertilizers in the hole before planting. You can add them into the planting holes after you dig them before you sow the seeds. Some of the most common options are baking soda, bone meal, coffee grounds, eggshells, Epsom salt, and kelp meal.
  • Mulching: By adding mulch to the soil, you will be able to maintain moisture and prevent dirt from splattering onto the bottom leaves. Use organic mulch to cover 2 to 4 inches thick or an alternative option such as bark chips or hay.
  • Sunlight: Make sure to offer your seedlings a lot of light to promote healthy and strong growth. Without enough sunlight, the seedlings will be leggy and long which is the thing to avoid. If it is not sunny outside, get a grow lamp so that they receive what they need.
  • Water: Care for your baby tomato plants by spraying the soil with water to moisten it. When the plants get bigger, use a small watering can or teapot so that you can easily water them.

Tomato Growth Stages

When it comes to tomato growth, there will be 5 different stages that you should pay attention to. Each stage may take different days depending on the light, nutrients, soil composition, and temperature. Those important stages are:

  • Germination: 5 to 10 days
  • Early growth with initial leaves: 25 to 35 days
  • Vegetative period: 20 to 25 days
  • Flowering period: 20 to 30 days
  • Early fruiting: 20 to 30 days
  • Mature fruiting: 15 to 20 days

The best fertilizers for tomatoes at different stages should have different NPK ratios. Choose a slow-release fertilizer during the planting stage to provide all of the vital major nutrients to aid their growth. When tomato plants first start their growth cycle, they will require more nutrients to support their leaf, root, and stem development. This stage requires a balanced NPK ratio so that there are enough nutrients for their growth.

As your tomatoes begin to develop fruits, then you will need to provide them with more support. They will require a small alteration for healthy flower production, fruit development, and resistance to diseases. The moment they mature, they will need fewer nitrogen levels and more phosphorus and potassium along with a few micronutrients. Don’t forget to provide them with calcium during this stage to prevent blossom end rot and promote fruit setting.

Best Fertilizers For Tomatoes At Different Stages

Tomatoes are not too difficult to grow when you know what to do, and fertilization is important. The first thing that you have to know is that the best fertilizer for tomatoes should consist of macronutrients. Those are nitrogen, phosphorus, and potassium, and the tomato fertilizer ratio of these nutrients will change during each growth cycle. Nitrogen takes care of the foliage, but make sure that it is not too much because it leads to bushy plants. Phosphorous is beneficial for the growth and development of the roots and fruits during the initial and final stages. Potassium helps tomatoes to grow rapidly and produce flowers and fruit.

How To Apply Fertilizer To Tomato Plants

Different tomatoes at different stages require different ways to apply fertilizer. More than that, you also want to know that the types of fertilizer also have different ways to apply as well. Just a few important things to have in mind, and you are good to go.

  • If you buy a plant from a nursery, it is essential to follow the instructions closely and never go over the recommended amount.
  • With liquid fertilizer, make sure to pour the diluted mixture into the soil around the base of the plant. At the same time, don’t water too close to the stem as it can burn the stem along with the roots. Make sure to water slowly, and keep a distance of around an inch from the stem. This is to prevent any backsplash on your leaves to damages.
  • For dry fertilizers, sprinkle them on the soil surrounding your tomatoes and gently work them in. Just like liquid fertilizers, don’t apply them too close to the stem. Keep a distance of an inch or two so that the nutrients are not too far from the tomatoes’ roots. Then water them deeply and slowly so that the fertilizer can release nutrients for the plants.

How To Choose Fertilizer For Tomatoes

What you have to know about choosing the right fertilizer for tomatoes is that it is not about the fertilizers alone. Your plant and soil nutrition is the key to growing juicy and plump tomatoes with abundant yield. In order to choose the right fertilizer, you have to know which type works best with your soil. There will be 3 steps to follow when it comes to checking the soil so let’s take a look.

Step 1: Garden Soil State Check

The first thing that you want to know about growing tomatoes is the soil conditions. You want the soil to contain magnesium and nitrogen because they are the best tomato plant food. Doing a soil test allows you to know the level of acidity and number of minerals in the soil. If the soil is sandy, it can reduce the effectiveness of fertilization and you don’t want that. Know what your soil needs, and provide it with that so that your tomatoes can grow healthily and properly.

Step 2: Tomato Growth Condition

The second step is to monitor the growth of your tomatoes when they are at different conditions and stages. If you want your tomatoes to have a strong root system, make sure to choose fertilizers with high levels of phosphorus. And if you want them to have a full bloom, then go for fertilizers with a balanced amount of nitrogen and phosphorus.

Step 3: Choose The Fertilizer

Before we talk about fertilizers, you have to know about the NPK ratio first. NPK stands for Nitrogen, Phosphorous, and Potassium, and a good tomato fertilizer ratio should have a proper balance of these three. Some of the most common ratio rates are 6-24-24, 8-32-16, and 10-10-10. The higher the percentage complex blend NPK ratio with extra potassium, the better the soil. And that also means the more nutrients your plants will receive.

Along with the NPK ratio, your fertilizers for tomatoes should contain micronutrients as well. Micronutrients are among the things that plants need as they have essential nutrients that the plants need. Some micronutrients such as sulfur help to collect light so that the plant can grow strong and healthy. As for calcium and magnesium, they help to neutralize harmful substances in the soil. This is to ensure that your plants can benefit with healthy growth by being in a more balanced right soil environment.

Things To Consider When Buying Tomato Fertilizer

Once you know what your soil needs, then it is time to think about what to look for in the best tomato fertilizers. The thing that you want to know is that each garden and tomato has its own characteristics. So there is no single fertilizer that work best due to many factors. Some of the important factors to consider when buying tomato fertilizers are below so check them out.

Fertilizer Application Methods

Different types of fertilizers also mean different ways to apply, and you need to consider that as well. The most common way to apply granular fertilizers, for example, is with a mechanical spreader or shaker container then water them in.

NKP Ratio

The soil’s composition and ratio of its NPK ratio will determine the ideal fertilizer for your tomatoes. Once you did your soil test, then choosing the right fertilizer will be an easy step. Another thing to have in mind is to not feed your tomatoes too much nitrogen. Some of the most common soil compositions and ideal NPK ratios are:

  • Composted and well-balanced soil will need fertilizers with NPK of 4-6-3.
  • If the soil lacks nitrogen, a more balanced fertilizer is ideal so go for a 10-10-10 NPK ratio.
  • In case your soil is rich in nitrogen, consider planting broccoli, Brussel sprouts, kale, spinach, or sweet corn instead. These crops requires large amounts of nitrogen to thrive, and they will help you balance the soil for next year.

Organic Quality

When it comes to homegrown crops like tomatoes, it is advisable to use organic fertilizers. It is better to grow healthy tomatoes that are free from chemical substances or other harmful substances that affect your health. And since you grow tomato plants from seeds so it is better to go for organic fertilizers.

Pack Size

Another important feature to have in mind when buying fertilizers is the pack size. There will be two things to consider regarding this matter: the size of your garden and the type of fertilizer. If your garden is small, then you don’t want to buy a big pack. That is because you will only need to fertilize your tomatoes during the growing season. In case your garden is big, then it is wise to go for a big pack since it saves costs.

The type of fertilizer also plays an essential role in this aspect. If you buy granular, spike, or water soluble, then it is okay since they are easy to store. At the same time, you also want to check the expiration date of the fertilizers as well. Just because they are easy to store doesn’t mean you should buy a lot because they will go to waste.

Quick-Release vs Slow-Release

When you buy fertilizers, you will come across the quick-release and slow-release types. Knowing the differences between these two is going to benefit you and your plants in so many ways. So let’s find out some of the details of these two fertilizer types below:

  • Quick-Release: is also known as water-soluble nitrogen (WSN), and it provides nitrogen to plants immediately. This type of fertilizer usually lasts for up to 3 to 4 weeks, depending on the rainfall conditions and temperatures.
  • Slow-Release: or water-insoluble nitrogen (WIN) comes in two varieties, and they last longer than quick-release fertilizers. The sulfur-coated varieties last for about 8 weeks while the polymer-coated varieties can last for up to 12 weeks.

Tomato Fertilizer Types

When you search for fertilizers, there will be a few certain types that you will come across. The 4 most common ones are granular, liquid, spike, and water soluble. We are going to discuss all of their details below so that you have a clearer idea of tomato fertilizer types. Let’s take a look and see which one is the most ideal fertilizer for your tomatoes.

Granular

There are many good things about granular fertilizer because it promotes healthy and tall growth. It is also very easy to store since you can keep it in a cool and dry place for several months. The best part is that its effectiveness remains the same, and you can use them in edible garden as well. This type of fertilizer helps with soil nourishment during the growth cycle to promote a healthy root system. Both quick-release and slow-release are good, depending on how you want to use your fertilizer.

Liquid

As for liquid fertilizers, you will need to dilute them with water, and it is also pretty easy to apply. You can simply apply liquid fertilizer whenever you water your plants, and reapply it every two or three weeks. Liquid fertilizer is available in both inorganic and organic options for you to choose from. It is also very to store since it comes in a container, and there is no heavy bag handling at all. The only drawback is that liquid fertilizers don’t last long so you will have to reapply them quite often.

Spike

Spike is one of the most popular types of fertilizers for tomatoes that is also very easy to apply. Coming in the shape of sticks, the application is rather easy and simple. All you need to do is insert the stick into the soil near the base of the plant. It is a slow-release type that will continue to feed your tomatoes for weeks or even months to come. This type is also perfect for beginners out there as well since it is extremely simple to use.

Water Soluble

What’s so unique about this type of fertilizer is that it is in the powder form. It dissolves in water, and it is very similar to liquid fertilizer. Water soluble is amazing because it has a combination of easy storage and fact-acting capabilities which has the best of both worlds. It makes sure to deliver all the nutrients that the plants need for healthy and strong growth. This type also comes with inorganic and organic that works differently to match your preferences.

FAQs:

What amount of fertilization do tomatoes need?

This is when you need to fertilize them so that they have all the nutrients and support for healthy growth.

What is the best tomato fertilizer ratio?

The best tomato fertilizer ratio depends on many different factors. The key is to make sure that it includes NPK and other micronutrients that tomatoes need to grow.
