rusty bits....

[binley100]

One lot of tomatoes (costoluto fiorentino ) have tiny little rusty coloured particles on top of the compost, although the plants look nice and healthy. Is this bad Help please.

Not the end of the world...just an algae growing...happens occasionally...normally when compost has been a bit too soggy....not usually a problem but pot on soon just incase they damp off (rot at soil level)

I'd discard the top 1/4 inch of compost before you bury the rootball at potting on

You can... water with tap...helps a bit with young seedlings.
-Try to water from the bottom only.
-Remember young plants don't drink much
-Don't overfeed young plants as excess nutrients can also be a cause
