How do you know when beets are ready?
I planted beets for the first time a couple weeks ago. The little seedlings are up and I started to thin them a bit - from what I've been told I need to leave a couple inches in between each plant to allow the root to form - but I only pulled a couple seedlings because I wasn't sure.
I have two main questions - how far can I let them go before thinning? I'd like to let the tops grow a little bit so I can use the seedlings I thin out for beet greens, but I don't want the remaining beets to suffer. I'd rather lose out on the thinnings than lose out on the beets.
Second - how do I know the beets are ready to pick? Just pull a couple up here and there and check the size?
