I have to disagree that powdery mildew is only a problem on the Pacific coast. We are completely opposite geographically. and PM is a notable problem here. Not just on roses, either.

Around here, if you haven't been treating a rose bush for fungus prevention, you can be almost certain that PM will show up on it by late summer. We don't spray our Knock Out roses and many of our other shrub roses for black spot, and by late summer, we generally have to take some action because of the PM.

All of our OGRs get PM also, but on the ones that aren't repeaters, we don't do anything about it. They may look awful but otherwise, they seem to work through it with no lasting effects. They aren't going to bloom at this time of the year anyway, so it really doesn't matter how they look. .

A few roses, like Home Run, seem to be immune to PM, but those are the exceptions. Otherwise, we've found that we can clean up PM very effectively with Green Cure (potassium bicarbonate plus spreader sticker)

Dr. Walter Lammerts, who created Bewitched, Charlotte Armstrong, China Doll, Chrysler Imperial, Golden Showers, Queen Elizabeth, Sunny June and dozens more commercial roses; and who is responsible for the creation and introduction of the Descanso Hybrid Lilacs which most of us have seen and/or grown (Lavender Lady, Angel White, Descanso Pink among others) which will flower in milder climates, proclaimed the Griffith Buck rose, "Maytime", "Immune to powdery mildew."

Maytime can spot a bit, but in all the years I've grown it, there has never been one instance of either mildew or rust, the two most frustrating diseases in my climate and conditions. Perhaps not everyone's cup of tea, but very much in the mold of a Pink Knock Out. If mildew is a large issue for you, consider Maytime. It does NOT mildew in any conditions I have ever seen it in, nor under which I have ever tortured it. Kim

My guess would be rats or squirrels. If it was something larger like a deer, horse or cow, they would have simply ripped the whole stem off instead of gnawing through the side of it. That was caused by something smaller which could get down inside the cage. Kim

Keep in mind you'll have a lot of rose petals falling right in front of the garage door--that might get tracked in on feet or rolled in via tires or blown in via breezes.

I mention this because I've got a big climber over my front door, and I've always got petals all over. The front entry is always a mess. Some people would not be bothered by this, while some would--just something for you to consider in your planning.

Maude, I can't see your picture -- and I very much wanted to do so!

Roses Unlimited in Laurens, SC. I will definitely pay them a visit! How fortunate that this is close by.

I hadn't anticipated that petals would fall in front of the garage. I think I can live with that . . . but I may bump things around a bit so that my house-entry-door isn't right by the garage door. Separating them by a few yards will help keep the petals out of my house. I can live with petals falling on the driveway, but I'd rather not have them dragged into my house.

I'm so glad to hear that this project is something within reach of an average gardener. Thank you so much!

I don't know how common the Gardena brand is in US, but I have a pair of very good ratchet secateurs from them. It is on the web as "Comfort Ratchet Secateurs SmartCut - Gardena" and I'm sure there are similar stuff from other makers.

I have never tried the Bosch Ciso cordless secateur, but it might be good when you need something easy on the hands. A little help from electrical power might make a difference.

My favorite is a secateur these days is a model with wooden grips by "Joseph Bentley". It fits well in my hand and I can work all day with out too much strain. It is guaranteed for 25 years, but I need to tighten the bolt now and then, and oil it a bit. It is not as care free as some, but the handle is rather good even compared to Felco models. It wasn't expensive at all. I managed to ruin the large one for some reason, it sort of hangs up when cutting, but the small lady model is great.

I suppose it's all about finding something which will fit in you hand and work with your strengths and weaknesses. Maybe a shop with a good selection will let you try out different ones.

The New York Times had a recent article on this topic, linked below.

I use the Radius hand tools. I have also found that the Bionic Rose Gloves help keep my hands from tiring when pruning. You might also want to investigate ratcheting pruners. I couldn't get the hang of the Felcos with the rotating handle, but they do have the #6, made for smaller hands. Using loppers for the thicker canes helps as well. Best wishes!

Since your 5.5' pillar is a rather small structure upon which to grow a rose in California, you need to be looking for a rose that doesn't grow very fast or that doesn't mind heavy and frequent pruning. I assume you want the column itself to stay visible and conspicuous. Also, unless you are happy to spray fungicide regularly, you want roses that California growers consider resistant to powdery mildew and rose rust diseases. Are the repeating damasks resistant?

I don't know whether you were considering it for the pillar, but 'Cramoisi' is a very full, bushy rose that would hide the pillar. The same would be true of most old tea and china roses.

There are two ways to pillar a rose. With stiff-caned varieties, you can tie the canes vertically and cut them back after blooming to different heights, so that flowers will come at different heights, not just at the top. The other (and nicer) method is to use a variety with very flexible canes that can be wrapped in a spiral. Wrapped canes will produce blooming lateral shoots all along their length. For the best effect, choose a variety that makes short blooming laterals rather than long stems.

So, for the pillar, you want a variety with moderate vigor, flexible canes, short stems, and resistance to California diseases. I don't know about Santa Monica, but some roses suitable for a 6' pillar around here are 'Ballerina', 'Tradescant', 'Weeping China Doll', and 'Sweet Chariot'.

Hi all,
Does anyone think that Louis Phillipe could work as a shorter pillar? I would really like to go red there I've decided. If there are any red teas that come to mind, I'd love to hear your suggestions as well.

Thanks for all the help,
Jay

It sounds to me like you are worrying about the wrong things. Clay is good for roses. It holds water and nutrients. PH is only a problem if you want to grow multiflora hybrids or roses grafted onto multiflora. Then you do need to drop the pH so it is acidic. It is much easier just to avoid those roses, particularly at first.

Unless you are planting specimen shrubs, like R. hugonis, don't dig and amend holes, but dig and amend beds. It is a lot more work up front, but once done, it is done. Amend the beds with whatever organic matter you can get easily and/or cheaply. Unless you raise animals, don't expect enough of it to come from your property. Any aged manure or compost is fine. I usually dig down about 1 ft, and add an inch or two of manure, the mix it up.

Get your samples from a spot not amended. That way you have a base mark to go on. It wouldn't hurt to sample the amended area too!
An organic is anything that has to rot to breakdown. Chopped leaves are free and real good. I use the bark mulch I get from a tree company. Horse manure is good if it's aged.
Start with you soil sample and we'll go from there

petrushka

thank you, it does look like wachurana, except it has fewer blooms. I am not sure if it reblooms - it just finished now. i'll keep a look-out. I took a few cuttings and will try to root them. seems it's a rambler - so can it be trained/tied to a fence? would it spread at the same pace or slower?
here's a pic, showing more faded blooms and some clusters. can it be grown in a container by any chance? what size would be suitable, knowing that it spreads a lot. of course, I'll prune it and keep it small.
can it be overwintered in a pot on a terrace?

r. wichurana poteriifolia. It does repeat some, but sporadically. I don't think it would be happy in a pot--most roses aren't and this one wants a lot of space. It gets very long runners, which will root themselves. Best as a ground cover, good for slopes or an place you don't want walked on.

farmerduck: I have tried Milorganite and blood meal.
The only thing that has worked is cages. I had anchored them in 4 places and it was a pain to unhook them to tend to the roses. I found out that the weight of the cage is enough to deter the deer so they are a lot easier to manage. I just made a smaller cage for buff beauty and cut down the high side to account for the slope. Any growth over 3.5 feet is left alone by the deer. Climbers would be ideal.

I share with the deer. Sometimes it is two steps forward and one step back, but mostly they just nibble. The only roses they have severely damaged are [newer] hybrid teas, so I don't grow those.

I've had the best luck in the late summer/ fall. However, then you have to find a place to store your roses until spring. I kept mine under lights.

If anyone wants to trade rooted cuttings, let me know! I like multi colored, striped, and old English type roses.

It depends totally on your chosen gardening style. Some gardeners like their roses to have enough room to be separate, neat, tidy, surrounded only by mulch, and not touch other roses. Others (I am one of these) like the lush look of roses intermingling.

I have so many roses and so not enough sun in my garden that I would plant a climber on your fence in an instant - closer to the fence, and to the right of your AD. You can train it horizontally along the fence once it gets going. Re depth, you can sort of espalier it on the fence and keep it very shallow. I have a climbing tea (which are famous for spreading out) rose which I have done this with. It is growing up the wall of our house in a rectangular bed that is only 8 inches deep, alongside of our narrow driveway. So, I have had to keep it out of the driveway. It had to fit between the wall of the house and the driveway, until it got 10 feet tall, after which there was a little more room. It is now over 10 years old, over 12 feet high, 7 feet wide, and only about 12 inches deep. Very happy and blooms all of the time. So, I agree with catsrose - go for it!

If you're growing Abe as a bush and you keep the Could 10 well trellised I think it would work out fine. Sometimes climbers tend to get those bare bottoms anyway and Abe would cover that up nicely.

I live in east Texas, 2 hours from Houston. After spotting this bug at night while I was outside near some lights, I found that the June Bug, which is common in our area this time of year, was the culprit who had been chewing on my roses. I use an insecticidal soap spray, cant recall who makes it, but you can get it at Walmart, Lowes. Spray on buds, leaves - this should stop whatever is chewing. As for wilt, the above posts are correct. If you have just planted your roses, they may exhibit wilt for a few days - just keep them well watered - and make sure you didnt plant in a hole that retains water - this can make them wilt. I read on the forum that it is really good to disbud for awhile, let the roses work on growing roots, not blooming. I now disbud all my newly planted roses for a couple of months. Maybe even prune them back a bit so less plant to have to keep moist. I usually prune my roses back a bit before planting. Also, just the heat itself might make them wilt until they get established. Just give them some time, they will probably be fine. Good luck!

Do you have any more pictures of that rambler?

I have been growing Mutabilis for years now. It's in a large pot and I bring it inside for the winter. It blooms even then. For one or two years I had it in the ground, left out for the winter. But each spring it had to start all over again. So far,!the way I'm doing it now seems to work.

You have some beautiful roses.

kind of thought they had died because they were covered in the naked lady foliage for months.

That reminds me, my neighbor has a lot of Amaryllis belladonna in front of her kitchen window, and she said the other day the first one bloomed. As her husband walked into the kitchen she said, "Hey, look there's a naked lady!". Her husband nearly fell over running to the window.

He wasn't expecting to see a plant.

My friends from a favorite online chat (not a hook-up chat but a hobby/profession) used to enjoy my the sharing of the link to a photo of a "Neked Lady" to the trolling guys that would pop in and looking naughty photos.

FYI, the yard is full of Naked Ladies right now...hehe

Or, if you are in a mild climate zone, you might plant the bush form of 'Mlle. Cecile Brunner,' or perhaps 'Perle d'Or.' Closely-related, both "Poly-Teas," these "sweetheart" type roses,with their clusters of small, sweet, pink or apricot blooms, were commonly planted to mark the resting places of very young children, or infants.

A strong, healthy, and vigorous rose of any name is better than one with the "right" name. You don't want to compound the grief by presenting the heartbroken family with a problem rose.

Very sorry for your loss.
