How to plant the tomato plants deep?

Choose a good soil

The soil that you are using for tomato plants should be of great quality, and the soil should be light. The roots in depth shouldn’t get too much load. The fluffy soil keeps the roots healthy. The hard and compact soil will suffocate the roots and lead to the growth of microorganisms that can damage the roots. 

Take measurements properly

The tomato plants should be inserted into the soil about two-thirds of the plant’s length with the root ball. So you need to dig the holes according to it. The hole should be deep and less wide. 

Take the plant out

The tomato plant should be taken out of the container and then place the tomato plant in the hole. It is also important that if you use the container then the container should be larger than the previous container in which the tomato plant was. 

Pour the soil over 

The soil should be poured over the plants about 2 inches, you can also add mulch if you want. 

Water the plants 

Water the tomato plant when the soil seems dry. Make sure the watering is done lightly and deeply. 

What are the two methods to plant tomatoes deeply?

Deep hole method

The tomato plants when are getting transplanted make sure that 4-5 leaves are above the soil for new growth. Make a deep hole into the soil and mix the slow-release fertilizer into it. The stem should be deeply placed in the soil because the roots are shallow and the roots will emerge from the soil. Using this method is quite easy and also gives good yields. 

Trench method 

In this method, you don’t have to dig deep holes but make use of shallow soil in a smart way. The trench needs to be dug and then laid the tomato horizontally. The trench method needs to be done gently otherwise you might break the stem of the tomato plant. The plant stems grow vertically later towards the light.

The seeds if planted too have the least chance that they will grow due to lack of light. Wait for a few weeks if the seed grows. If you don’t want to wait, you can take off the thick layer of soil and make it a little thin so that the seed gets some sunlight.
