Potting

Completerookie

Hi All
Its my first time growing vegetables. How big do my courgettes, squashes, rainbow chard and hestia beans have to be before I pot them into bigger pots!?

They need to have their proper leaves, and be filling the pots with roots before moving them on. 
Most of those look as if they only have their seed leaves, so it's too soon

Courgettes and squashes can get big enough fairly quickly indoors so I usually start mine off in slightly bigger pots than my other indoor sowings, to give the roots enough room to grow. I reckon yours may struggle for room fairly quickly so keep an eye on them. As for your chard, as Fairygirl said above, wait a bit yet.

The first leaves to come through are the seed leaves (cotyledons). As @Fairygirl says you need to wait until the "true" leaves show and roots are showing under the pot. Will you be able to plant them out or are you having to pot them up and growing them indoors?

It's the perennial problem - having enough room to pot plants on if they all germinate and it's too early to put them outside. Hopefully, your conditions will improve enough that you can get them outside before they take over your house!
The best solutions are to have fewer sowings, so that you have enough room when they're potted on, or stagger them, so that the later ones can go outside at an earlier stage because conditions will be more suitable. We've all been there though
