Thanks for the info, Kim. I'll have to try the systemic. As far as I can tell, watering is not an issue. I watch the soil and we've had decent, but unseasonable rain. Many of my other roses have problems with rose slugs, too. I've been hand picking all day. ICK!

BTW, I have a yellow rose I think is worthwhile. I have a compulsion to plant self pollinated rose seeds, and this rose and its sister are from a set of siblings from 'Compassion'. This sowing has given me some lovely surprises. Out of about 24 seedlings, a dozen survived, of those, several were very similar to 'Compassion' with just slight color difference-more peach than pink-and shrubs, not climbers. One is a large climber, and has BIG, beautiful, five-petaled, pale pink-edged magnolia-white blooms. They remind me of
Sally Holmes', but more pale yellow to cream. The buds are rosy, and very pointed. Two siblings bear amazing blooms. They are medium sized HT in form, taxicab yellow, non-fading and on long stems. The foliage is spotless disease-wise, and the rose slugs have had minimal effect. I had an unusual greed seedling, as well. It was very, very green, congested with ruffled petals, and lovely. Unfortunately the plant was weak, and it died. Then there's a HUGE climber with creamy-white, whisper pink petals. It looks like the 'Compassion' seed parent, 'White Cockade', but for the color, and many more petals. It's also extremely fragrant, and my garden is very cool and sometimes foggy. I'm trying to keep it in bounds in my tiny garden. I think it will do well with pegging, or horizontal training.

I do the self-pollination thing, because I'm exploring the manifestation of recessive genes carried by modern hybrid roses. I started this with over one thousand 'Cl. Fourth of July' seedlings. THAT was a magnificent experiment. All the seedlings were single or semi-doubles, most were striped. Some were pink and white, many were nearly identical to the mom plant, some were (and this is my favorite) red-on-red, semi-double climbers. Some had deep scarlet solid red petals with a black-red edge, and a few were pale yellow to white centered red shrubs. Sadly, most were left in Georgia when I returned to California. I have a C4J here, though, so I may try the experiment again.

If you're interested, I can send you a blog address where I've posted some pix.

Anyhow... Thank-you for your responses.
Jeff

Absolutely sure... Sometimes I have to buy roses from sources that aren't close. So far, I haven't found a California vendor.
