How Deep Do Tomato Plants’ Roots Grow?

How deep do tomato plants’ roots grow? A tomato is essentially a very lazy plant!! Its roots grow as deep as they need to grow.

A Quick Note On Tomato Diversity

Tomatoes are insanely diverse fruits! I have grown giant Crimean black tomatoes, little cherry tomatoes, moneymaker, little wonder,  yellow pears, Beefsteak rainbows

When we look at the incredible diversity of tomatoes out there, one thing is very useful. We can broadly divide tomatoes into two broad growth styles of plants.

Determinate and Indeterminate Tomotoes

Determinate Tomatoes

Determinate tomatoes stop growing when they flower and produce fruit. These tomatoes tend to look more bush-like and produce crops of fruit that all ripen at about the same time.

These tomatoes just keep going – they can actually get a bit out of hand, much like a squash plant can. They take over! Classic wild cherry tomatoes are a good example here.

Indeterminate Tomatoes

A tomato will produce a taproot where the seed germinates. Taproots grow down in a deep direct way and branch laterally. The depth of the taproot depends on the genetics of the plant

Tap Roots

The fruit just tastes better if the soil is deep and rich. Homegrown tomatoes are one of the greatest summer treats in a garden.
