Thinning Arugula Seeds Arugula seeds generally germinate about a week after planting, so when seedlings reach 1 inch tall, thin them out so that the plants are spaced 3 to 4 inches apart.
How big should seedlings be before thinning?
Seedlings should have at least two pairs of true leaves and be about 3 to 4 inches (8-10 cm.) tall before thinning. Evening hours are a good time to thin seedlings as the cooler temps and darker conditions make it easier for the remaining seedlings to bounce back from any stress they may have received.

When should you start thinning your seedlings?
In general, consider thinning once the seedlings are showing a pair or two of true leaves rather then the seed leaves they first germinate with. If you’re thinning seedlings growing in containers, the aim is usually to leave a single, healthy seedling behind in each pot, cell, or pellet.
