Timing query

Campanula muralis will at least double its size this year - don't worry about planting it too close to other things, you can always dig it up, split it and replant. Coreopsis should spread about a foot to 18 inches, helianthemums, well they can spread like the devil once they're settled in, but not this year. Apart from the coreopsis, they're all plants that can be dug up and split either spring or autumn, so if they get too big, you know what to do! Bear in mind you probably won't get flowers on the campanulas this year - it's likely they've already done their stuff, though you might get a few. Helianthemum later on for flowers, and coreopsis should start as soon as its big enough, if its not out already. Just keep 'em watered.

cheers bamboo, the campanula m was sent with flowers so i atleast get to see them, the white-blue chips look like the flowers are closed ready to come and the coreopsis is about 8" high at the moment,helianthemums are only little plugs, just waiting on the nasturtium seeds now, also whilst i was planting them i discoverd a red ants nest, i disturbed them enough to have them start moving there nest of eggs but would suggest doing anything else with them?

If you are able to, without pouring it on your plants, pour boiling water on the nest - or use an ant station to get rid of them. They will 'lift' your new plants out of the ground if they get amongst the roots.

I'd try the boiling water trick - you need a kettle full, open up the soil where the nest is and pour it in before you plant. Awful, isn't it? Then go back out later on, dig around and see what you can see - if there's still millions of ants, try it again, and you could get some ant powder and sprinkle that in the soil a bit too. Best not to plant over an ants nest while its active, for the reasons Spritz says.
