I only planted these 1 year ago and they showed signs of the mildew within a couple weeks of planting them. Since then I have been plucking, spraying, pruning and watering properly. I even cleaned up the foilage in the fall. These plants are in a well drained southwest location, even out in the open so its a joke that all 7 have the mildew. I'm thinking about pulling out 4 of them. The nursery has already agreed to take them all back, its just a ton of work to take these 3 - 4ft out. My concern is that if its this bad this early, with maintinance and with conditions that aren't condusive to the PM that I'll be fighting with them forever. What happens when the get 6 ft tall? My other MAJOR concern is that the PM will spread to other plants. I have maple, spirea, pear, viburnum, forsythia and lilac within close proximity. I know the host my be specific but I can't get a straight as to the PM spreading or not. I guess I need to find a replacement that is more pest and disease resistant. Any suggestions for 7ft x 7ft plant that will get southwest exposure, likes a well drained soil that will get dry, so they need to be drought tolerant once established. Of course I need good shape, good branching and an ornamental feature since they are in a high visible area. Lastly needs to be PM resistant, lol.

I was on vacation, returned yesterday, happy to get so many responses to my post, and wonderful feedback. Coolplantsguy - yes, I do love peonies and heirloom plants for that matter, I just don't have the room though I admire them in my neighbors yard. The one we had toppled from the weight of the blooms, I don't know the variety, they were here when we purchased. Thanks for the suggestion, I will consider if I ever find the space again...my lawn gets smaller with each passing year. LOL. Pat, you make me chuckle. I'm like you. I spend so much time planning and thinking things through over the winter, only to find later that I don't like the combos or placement, so I plan again for next year. Some of my plant combos happened by accident & some I've followed suggestions when researching companion plants. I'm still learning how textures compliment eachother, and other things I didn't know to think about a few years back, but it's fun to learn. Summer is too short though. Prairiemoon, I also have Astilbe planted next to my Annabelle, and I enjoy the contrast of the red plumes and darker foliage with the brighter green backdrop of Annabelle. I've learned it's best to NOT fertilize it once it's established, it makes the blooms too heavy and they'll topple. Still, the rain does make them flop, but mine usually bounce back, I have one staked with a support, but it was just planted this year. I also cut my dianthus blooms back before I left for vacation, and returned to a new flush of blooms, the foliage tends to yellow on me though, I need to stop watering, I didn't realize they're drought tolerant. I forget the variety, it's got blue spiky foliage and red flowers. I will have to do more research on hellebores...we added a raised planting bed/retaining wall with a row of purple leaf sandcherries on top, and I'm looking for an underplanting in full sun; the sandcherries will be trimmed into a tree form once established. For now, I planted yellowish hostas at the base for contrast, but I know they won't do well in full sun. I'm glad to hear about Sedum Angelina, mine will be delivered some time this week, now I'm really looking forward to growing them, I just worry about our new dog, she's so rambunctious - she's a chihuahua boston terrier mix, the cutest thing, she likes to grab my plants and tug on them..I'll have to get her some more toys. I was thinking of amending my soil for the iris, adding more grit for drainage, we'll see if that works. I had one aster that bloomed for me, but it was spindly, a combo of dry soil in this area and minimal sun, but my campanula that I moved not too long ago is doing much better, must be the sun. I have to move the asters, just trying to find a location. It's funny about the Autumn Joy Sedum, my husband keeps telling me to pot them up since I can't find the 'right' place for them, I'll have to try that. I do like the blooms, very pretty, and they grow amazingly large after transplanting a single stalk, very impressive. I will try to post a pic of William Baffin rose when I have a chance..the pic is not mine as mine is only a few months new and I'm still learning how to prune them to shape, but my friend has one along their property and it's a stunner, grows upright almost like a tree canopy, and does well in our zone without protection and is disease resistant, with prolific blooms, but I know they have to trim it back regularly, it's a monster. Give me a couple of days and I'll try to post here if I can figure out photobucket. Of the climbers, I have Don Juan and Sombreuil. They died back almost to the ground, but new growth emerged in the spring, so they're still puny and it's the end of July, though I also transplanted them in early spring. We'll see next year if they do better. I purchased Smokebush 'Grace' and 'Golden Spirit' - I've read there's some potential winter die back, mine is only a month new, but I've also heard that they grow like weeds once established, so even with winter die back they'll grow like crazy. 'Golden Spirit' has new growth in a pretty lime green color and grows more upright in form whereas 'Grace' fans out. 'Grace' grows at a house up the street from us and it's just beautiful, especially with the smokey plumes. I ask my husband to slow down every time we drive by. :) Phyl in Chicagoland, I'm embarrassed to post pics. I still consider my landscaping in the beginning stages, most plants aren't mature or established yet, I've moved a lot around, still a work in progress. I had problems with photobucket last time I tried, but I'll see what I can do. I'll tell you though, do an internet search on 'Nancy J. Ondra', I came across her website when researching plants (that's where I got my iris and lemonbalm combo inspiration from) - her garden is to die for, absolutely STUNNING!!! I peruse her garden pics whenever I get the winter blues. Mxk, I was also looking at the Iris pallida but wasn't sure if it would look odd to mix these with the non variegated type. If you like the look of Jacobs Ladder, it reminds me of a shrub, Carol Mackie Daphne. Same variegated foliage, with pretty spring flowers. Connie, this is also my first year with wave petunias and I love them, I have them in hanging baskets. I've read they are self-cleaning, unlike the regular petunias, but I still deadhead here and there. I'd do them again, definitely. The foliage is also very pretty. Gabby, I used to throw tags away, but as the gardening world became more intriguing to me, I've learned to write down the names of my plants on a 'map' of my yard...LOL. Mostly in an attempt to overcome winter blahs, I also compiled a list of plants that need deadheading, cutting back, dividing, etc. so I know what to do come spring. Daylilyluvr, ok, like I said I'm an 'advanced' beginner in the gardening world, still in my learning curve. LOL. I had no idea Sweet William was a biennial. I've had it for two years now, the blooms are stunning, but this year it got all brown and ratty after blooms were spent, I chalked that up to too much watering. I cut it back and it looks like a few blooms are starting to come in again, but I had to remove old dried stems. Web says if you don't let it self seed it will shoot up more stems and act as a perennial...looks like that's what's happening for me as I likely cut back the spent blooms last year too. Crunchpa, my favorite person from the container gardening forum. LOL. I have a TON of containers this year, maybe too many. It takes me over an hour just to water everything, and that's just the containers, but I think I got overzealous and overstuffed them this time around...still, I wouldn't go without my containers, I'm hooked. I love that moss sedum, I'll have to try it. You always have the best pics. I still have dirt to cover until everything is established, I'm waiting patiently though my transplanting doesn't help either. I was looking into that red hot poker at one point, if I remember correctly I think it goes dormant mid season and then comes back again later?? Or am I thinking of something else? Pretty. I'll have to research more of the suggestions here, though I'll probably be losing more lawn in the process. :)

Bingo, Dibbit! I think your air circulation explanation is the key - makes perfect sense! Over the past five years all the surrounding plants have grown incredibly really hemming these spireas in - in fact, crowding is why I moved the two earlier this year. The garden is raised, in a fenced corner backed by a timber retaining wall w/now pretty big trees (magnolia & Japanese maple) and a few suddenly huge perennials, all of which are definitely restricting air flow. Too late to move them this year w/out seriously disturbing their neighbors, so will definitely free them next spring. Meanwhile I'll cut them back again and baby them w/a home remedy - and thanks for the soda/powder correction, brain & fingers wern't connected! Thanks again!

My problem with the garden is every flower seems white. Need some color. The foliage looks nice. Flowers though to me are secondary to texture and foliage color, which in this garden is pretty good! I myself would not move the grass or sedge whatever it is. It makes the texture change. My garden is wild with overgrowth. It seems with perennials I'm always thinning them. Another suggestion is flower type, I don't see anything with spikes. You want different flower forms. Maybe a daisy form flower too. Irises etc. If you like the white look fine, but I myself would add silvers or silver foliage, or pastels would look great! Another consideration is early, mid, and late flowering plants. So it looks good all season. I myself am still experimenting, I doubt I will ever actually ever finish but keep changes things. Plus the fun of growing new plants. I have a flair for the unusual. My porch is full of tropical's, trees and plants like Pony Tail palm, Yucca tree, night blooming jasmine, etc. I have bamboo and cacti in the ground too. Some forms are winter hardy. It doesn't look typical! It looks eccentric, but I'm very much so! Mostly though I grow edibles and I'm into edible landscapes. I want to grow as many ornamental edibles as possible besides your normal garden. So edible dogwoods, June berries like Autumn Brilliance. Red leafed peach trees Weeping plum trees. A currant cordon on the fence, I like edible vines like Eastern Magnolia. Edible wild flowers are in the garden too. Strawberry and raspberry ground covers are next to be put in. Yes some raspberries are ground covers. I also grow regular raspberries too, I have 15 plants. I get 25-50 berries daily for 4 months. I have Pluots, and a Spice Zee Nectaplum. Indian Free peach that Thomas Jefferson grew. It is pretty much a jungle here! Many plants are small give me a few years, and I will show photos. It's still under construction.
