Self-sown annuals - thin out or leave them?
I've got quite a lot of self-sown annuals (largely Iberis and Limnanthes) popping up ranging from a few inches to just seedlings. Obviously they're a lot denser than any seed packet would ever suggest growing them. So I wondered, with hardy annuals that have self-sown, do you tend to thin them out or just let them get on with it?
Ultimately, they're better thinned out so that you have fewer plants, but they'll be sturdier, especially in the case of the Iberis.
You'll probably find many of them won't make it over winter though. Limnanthes are annuals, but I expect in some areas they may be almost perennial
I live in west central Scotland - not where that photo is...
To clarify, by Iberis I meant Iberis umbellata, the annual Candytuft.
The ground would be bare otherwise until the daffodils come up next year.
