green compost?

i have been tinekering today and have noticed that some of my compost is turnning green , they all have plants in so am wondering is it over watering what as caused it? if it is that will cutting down how much i water them solve it?

 

cheers or info , to be fair i thought i had been overwatering . total novice at this tho, lol

 

I get it on my containers, nothing to worry about.

To tell if the compost needs watering, dig your fingers a few inches down to see if it's still moist cos the stuff on top dries out quicker. Also with some composts you get a crusty later forming on top - I run my fingers around the top to loosen the compost.

 

I think it mucks up tiny, slow growing, seedlings. Plants that grow quicker / stronger are fine. Worth watering from below (stand the pot / tray in water for 10 minutes) and doing the "weight" method as John described - with practice its easy to tell whether the weight of a pot is "dry" or "wet".

I'd be careful about having a poke, in a small container the soil disturbance could damage a relatively significant proportion of the roots (although in a large container the impact is negligible of course)

A water/moisture "probe" and meter is another approach.
