How To Prepare Soil For Tomatoes In Pots?

If you don’t have proper space for growing vegetables and fruits then you should not lose your heart. You can grow your favorite plants in pots or containers. This is a great way of growing your food in your limited space.

Tomatoes are one of the famous vegetable crops that you must try. This plant produces fresh and juicy tomatoes for your kitchen. Homegrown fresh tomatoes are far better than store-bought tomatoes.

Never Fill Your Pots With Garden Soil

When you grow plants in pots or containers you can easily maintain the fertility of the soil. Always use high-quality soil and never fill your pots with garden soil because:

It is very compact and doesn’t have all the nutrients that are needed by tomato plants.
Garden soil has the best diseases that spread in your tomato plants when they are established in the pots.
The weeds can easily germinate in the garden soil. Weeds are unwanted plants that create competition with tomato plants for nutrients.

When you use a high-quality potting mix for filling the soil, it contains all the organic material that is required for the healthy growth of any plant. Soil is the foundation of any plant and your success in growing healthy crops relies on it.

Difference Between Seed Starting Mix And Potting Mix For Tomato Plants

People are confused about the seed starting mix and potting mix. There is a slight difference between these two because of the different ingredients.

If we talk about seed starting mix, it helps the seeds to sprout and develop their first set of leaves. The newly germinated plant takes food from the seed so there is no need of using fertilizers in the starting mix.

On the other hand, potting mix performs an entirely different function that’s why it is different from seed starting mix. Potting mix is essential for tomato plants because they are going to grow in it permanently.

It means the quality of the potting mix should be high so they provide a good home with food for tomato plants. It must contain all the essential nutrients for the healthy growth of fruit.

Why The Right Potting Mix Is Essential?

Soil is the medium from which plants absorb nutrients, oxygen, and water. Tomato plants grow stronger when you provide a suitable environment. When you use well-drained, light, and rich soil then tomato plants produce higher yields.

A high-quality potting mix holds enough moisture. When you grow tomato plants in pots then you can fill the pots according to desire which is not possible when you grow plants in the ground.

But it doesn’t mean that you can use any type of soil without thinking about what tomatoes need to produce fruit for you. If you use an unbalanced and unhealthy potting mix then young tomato seedlings will not thrive.

Right Size Of Pot For Growing Tomatoes

You should not compromise on the size of the pot you are using for tomatoes. Tomatoes need full potential to grow, that’s why they need enough space.

The size of the pot also depends on the variety you choose for growing. If you use a small pot then it will restrict the growth of tomato plants and the size of the fruit is also smaller.

Your plant will flourish if it grows on the right side of the pot. Spacing between the tomato plants is also important. It has a great impact on growth.

When you grow tomato plants too close then they will compete with each other for light and nutrients. As a result, they will become tall and leggy.

The minimum size of the pot must be 30 cm. You can use a 15 cm deep pot if you are growing a dwarf variety of tomatoes. The maximum size must be 25 cm and it can hold 10 liters of soil.

You should not use growing bags for tomato plants. Because the success rate of growing tomatoes in grow bags could be much higher. If you want tomato plants to develop a strong root system then you should provide them ample space. The size of the fruit depends upon the depth of the pot.

Whatever the size of the pot you choose for growing tomatoes make sure it has drainage holes at the bottom. Drainage is very important for your plants because excess standing water invites root rot and many fungal diseases.
