Buying Guide For Best Fertilizer For Tomatoes

Fertilizing Basics

Plants need nutrients in the soil for healthy growth; however, the nutrients supply reduces after every crop.

If there are not enough nutrients, trees and plants can’t function and grow to their full potential. Now is the ideal time for you to add nutrients to your garden soil.

There are various methods to do this: using leaves, wood ashes, etc. But the easiest and most effective way is using fertilizers.

The plant foods’ additional substances increase crop productivity and improve soil conditions.

However, always be careful with chemical fertilizers since they can be harmful to your health and the environment if not used correctly.

Nutrients That Tomato Plants Need

Nutrients are the life sources of plants. The 3 most essential nutrients (also known as the macronutrients) they need are nitrogen (N), phosphorus (P), and potassium (K).

  • Nitrogen is vital for foliage growth.
  • Phosphorus helps roots and fruits to develop.
  • Potassium is necessary for general plant growth.

Some micronutrients are also beneficial:

  • Magnesium and manganese maintain strong growth.
  • Zinc and boron promote chloroplast development.

When To Fertilize Tomatoes

If your garden soil is healthy and full of nutrients, you don’t need to fertilize it from the beginning.

It’s best to wait until the tomato crops start to set fruits to do it again. Only add fertilizer lightly every 10 to 14 days.

The evening, when the sun is waning, is the best time of the day to use fertilizer.

However, the sunlight can reduce the benefits of manure due to its heat. Thus, using it after the sun has set is a smart move.

Beware that your plants can wither from overfeeding, meaning they absorb too many nutrients at once. Therefore, it’s important to pay attention to the amount of fertilizer you apply.

How To Fertilize Tomato Plants

The fertilizing method depends on the stage the plants are at.

Suppose you want to fertilize while planting. In this case, you should mix the soil with fertilizer at the bottom of the planting hole.

Before you put the tomatoes into the hole, spread some unfertilized soil on top of the fertilized one, creating a layer that protects your plants’ roots from direct contact with the fertilizer as it can cause burning.

After the fruits have begun to set, you can fertilize them once again but in a small amount. It’s advisable to water them first; otherwise, they can absorb too much fertilizer, resulting in burning.

Spread the tomato fertilizer on the ground away from the plants’ base, about 6 inches, to get the best result. Don’t fertilize too close to the stem to avoid burning.

When To Stop Fertilizing

More is not always better. The benefits of fertilizing are great, but you need to know when to stop to protect your plants from overfeeding.

It is best to stop when the harvest period is about to set in. Late fertilizing can be the reason for the plants to focus on growing foliage instead of producing blooms.

Watering Tomato Plants

Watering can affect the fertilization process. Water the plants before fertilizing them to prevent burning.

The most important rule of watering is that you need to go slow and lightly. Use a drip hose to water the plants gradually at the roots, not the top.

Don’t over-watering your garden, however. It can wash the fertilizer away, so it won’t get any benefit it deserves.

Fertilizing every 2 or 3 days is enough, reduce to once a week when it gets cold and when the fruits have set.

Types Of Fertilizer

Granular Fertilizers

The granules come in 2 types: slow-release and fast-release, which usually come dry in a bag. You only need to water the granules to activate them.

The slow-release fertilizers continuously release the nutrients over time, typically up to 2 months or slightly more, depending on the heat and water.

As a result, you don’t have to reapply too frequently, saving you a lot of time and investment in the plant food. But this type of fertilizer requires time to release the nutrients, so be patient.

The fast release formulas, as their name suggests, deliver the nutrients faster. These usually cost less than the slow release types. But be aware of how much you apply. If you overdo it, you may burn your plants.

Liquid Fertilizers

These types need to be mixed with water before the application and a spray bottle or a hose, offering users optimal ease of use.

But liquid forms are considerably more expensive as they are not long-term and need to be reapplied often.

Synthetic Fertilizers

In other words, they are chemical fertilizers. They typically consist of all the necessary nutrients.

Unlike organic manures that can take months to act on the soil’s health, you can see their effects almost immediately with chemical plant foods.

Despite being easy to use, they can be harmful to your health and the environment. Thus, be cautious of how much you apply.

Organic Fertilizers

They are the safest to use in the garden and 100% environmentally friendly since they derive from animal or vegetable matters.

For example, compost, blood meal, bone meal, feather meal, etc., are organic manure.

They are the perfect option for those who love organic food and want to protect the environment. Nonetheless, organic composts may not be as effective as the other counterparts and usually have a strong odor.
