Roses - how far apart?

Would like to get some real world input (to augment on-line info) about how far apart roses should be spaced.
The area is So. Calif Coastal. The soil is good; enriched over the decades. The roses are in a path alongside the (unused) driveway.
Over the many years, I have left as much as 2+ feet between them, but wonder if they would be happy more closely spaced; then I could get in a few more plants. None of these are wild Floribunda; most are reasonable-sized.
Appreciate any advice.

What do you mean by 2+ feet between them? Is that 2 ft between centres of each plant or between the outermost tips of the branches?

****Most of them are 2+ft- sometimes 3 ft. on center, not between outermost tips.
****The new ones I just put in are barely 2 ft on center. They are doing very well; blooming up a storm. However, their tips are touching. My gardener said 3 ft. but also said the new ones look OK. Do I need to move them? (They occupy the place of a couple of nothing Floribundas; blooms were not that attractive; plants sprawled.)
NOTE: I am using asterisks to set off my replies, because something went wrong with a recent reinstallation of my system; carats have disappeared. Geek is not answering my pleas. Any ideas how to get carats back?

You have two potential problems. If too close you may get root and/or branch competition which can prevent them from reaching their maximum size and vigour. Competion for nutrients and water you can overcome to some extent by feeding and watering. The second issue is air circulation. If you get humid damp weather they may be more susceptible to fungal attack if there is less air circulation.

Look up help for your newsreader under 'replies' or 'quoting'. You need to tell it to use carets (or whatever character) when quoting text in replies.

Try using a real newsgroup reader instead of participating via Google Groups. I use Thunderbird from <http://www.mozilla.com/thunderbird/ . It's free. You might also look at <http://www.big-8.org/wiki/Newsreaders , which lists many othernewsgroup readers.
