Strange unknown plants in pots?

[Anthony_kat]

Some of my indoor plants have started sprouting unknown plants in some of my indoor plant plants. The garden its self it right next to my slightly open window is it possible some air-borne seeds have crept through and germinated????

Did a bird fly in and poop in the pot?

I don't think so its fresh potting soil

What kind of soil/compost have you used? It could well be that it held weed seeds already. It has been known to happen. If it is just ''topsoil'' has it been properly sterilised?

Pictures would help ID them.

Are you using any worm castings? Or does the potting soil contain worm castings? I've had random weeds pop up due to castings. I'd say your potting soil has somehow got "contaminated" with random weed seeds and has nothing to do with birds or traveling seeds near your established plants.

Sounds as if seeds have blown in and germinated.

Seeds are experts at distributing themselves in every possible way. If you gardened in a sealed greenhouse with an airlock I reckon you would still get weeds eventually, a seed would be on someone's shoe, or in their hair, waft on the wind through the airlocks or get in the water supply. Weeds developed on the edge, between the forest and the bare rock, they are survivors and have to be able to get about, seeds is their main route and they do it through diversity and sheer quantity.

Actually that's a lie I have pet cocktiels that like to sit on the edge of there pots that might have sprinkled a few undigested millet into my pots.

Yea that was my first thought as they are next to a semi-open window

Apparently it is Dobbie's multi-purpose compost peat free mix

Can get seeds germinate that's in the compost, i always had a few I just pull them out.
