We moved into our house last Winter and decided to let a full growing
season go by before tackling the gardens. The previous owner had quite
an assortment of perennials (lillies, daffodils, irises, and patch of
cana). As for what specific types of each, I have no idea. Most came
up and bloomed but we still had many that never flowered. They all
seem to be really packed in and I think they need to be spaced out.
What are my options in terms of replanting and perhaps moving some of
them? I know I'm running out of time before we get our first frost (I
think we're in zone 7A - northern virginia). After that, I know
there's really nothing I can do until Spring. How much longer do I
have this season?

Any suggestions or general tips? I'd hate to lose what we already have
in the ground and I think what's there can be used as a great start.
Hopefully I won't do too much damage through the learning process.

Also, if there are any basic guidelines for rose bushes, I'd appreciate
hearing them. We have a few scattered bushes that are pretty small,
but flowered very nicely. There's also an out of control bush that is
being crowded by the iris patch. Should I trellis it? I'm just
generally not sure what to do in terms of rose pruning and maintenance

Thanks in advance for your help. (as you can see I need lots of it!)
