Plant Tip: Tomato Stems Bumps

What are Aerial Roots?

What are these bumps on my tomato plant stem?

Aerial Roots


When you see little white nodes coming out of the main stem of tomato plants, that is completely normal. Although those look a bit scary, don’t worry - they’re just aerial roots!

Tomatoes have the ability to grow an entire root system from the stem, which is an evolutionary defense mechanism so tall tomato plants are not knocked down. If those nodes were to be in soil, a whole new root system would appear and anchor the plant more securely to the ground. This is an indication that you have a happy and healthy plant that is just looking for more space to grow!

Since this is a completely normal biological function, we do not suggest attempting to remove the nodes, as this may damage the plant.
