Help - My tomatoes have warts!

[seja]

All my tomato plants have grown what looks like warts (yeah nice) on their main stems. Is this normal??

[terrier]

What colour are the 'warts'? Tom plants are normally quite knobbly, just as long as the warts dont grow on the fruits you are OK

Toms can root from the stems, these may be attempts at throwing out new roots.

I know exactly what you are talking about and although they may look disturbing, they are nothing at all to worry about.

they are the feeding roots..the bottom roots are watering roots...apparantly
