Extensive damage on 5 rose buds on my 'Olympia' plant. Any ideas?

I have been treating my roses for thrips with Bayer rose and flower care (one treatment so far, the next will be in 5 weeks). I went outside today to see 5 of my rose buds on this plant to be completely destroyed--it looked like something just melted half of the bud right off. Is this thrip damage? Something else? I am feeling discouraged! *this was after a heavy rain, if it matters, and a week of hot, hot sun before that. 6A, SE Mich.

Any ideas on these tips from Field Roebuck's rose book?
Comments (27)Thanks, Kim, for the confirmation. I checked on Chinese chives, it's the same as garlic chives mentioned in Field Roebuck's book. He stated, "In at least one controlled experiment, when planted underneath roses, garlic chives completely eliminated spider mites and reduced aphids." Rose magazine site stated that high-nitrogen chemical fertilizer does encourage aphids. The Canadian website that advocated fall fertilization, rather than spring, cited less insect problems with earlier nitrogen fertilization for wheat fields. Garlic chives have white flowers, it is listed among the invasive species. In my experience with invasive species, it's the least invasive, since it can be pulled up easily. It's a tiny bulb - rather than invasive roots. If you cut the flowering stem off before it becomes seeded, then you stop the growth. I was hoping it becomes invasive enough to gather a gallon for making pot stickers -but it did not spread fast enough in our 40" inch annual rain and high germination in magnesium rich soil. I also have the American chives with purple flowers, this is invasive since it spreads by roots. This chives is more drought-tolerant than Garlic, or Chinese chives. Calendula, or potted marigold, is just as pretty but more drought-tolerant than regular marigold. Calendula host many beneficial insects, especially green lacewings. These lacewings fly around and eat Calendula's pollens. But they give birth to larvae, named aphid lion. More info: "Each lacewing larva will devour 200 or more pests or pest eggs a week ... After this stage, the larvae pupate by spinning a cocoon with silken thread... the adult will live about four to six weeks...Each adult female may deposit more than 200 eggs. Nectar, pollen, and honeydew stimulate their reproductive process." What I like the most about garlic chives, or Chinese chives is its medicinal and anti-inflammation properties. It's especially yummy in potstickers, better than green onions. I like Calendula (comes in bright yellow and bright orange), since they are drought tolerant and still bloom during frost. Below is a picture of Calendula in my tomato garden:...See Morewhat's on my rose buds?
Comments (6)Hmmm...not had problems with them on bearded iris. Guess I provide them with too many roses to devour. They are making a mess of my SA. It's their prime target. They're hitting roses this year they never touched before...like Soutine & Carefree Wonder. They'll even eat daylilies and they have shredded the pink loosestrife...there's NOTHING left of the plants. It looks absolutely gross now. Guess I'll prune it to the ground. It's too bad because the bumblebees really love the stuff. Stupid, despicable JBs....See MoreMy large jade plant has a bit of rot...any ideas?
Comments (20)D, I know that bark is organic, and that's why I said the mix was "primarily inorganic" - meaning that it is mostly a mix of Perlite, Turface, and Marble chips. While a mix like this is certainly capable of holding a good amount of moisture, it is also very durable and won't hold as much *saturated* water as an organic rich mix. I don't use mixes high in organics - the opposite in fact. When it comes to succulents, my mix is 1/3 bark or less. That's a ratio that many of us use: 1/3 organic (bark), 2/3 grit (turface, pumice, granite, quartz). Ron, the reason we add bark is because it doesn't hold an exceptional amount of water, but rather equalizes the moisture between the ingredients. Further, bark is very durable compared to something like peat or coco coir, and in general it lasts longer than one should go between re-pottings. The incidence of nitrogen immobilization is overstated, in my opinion and experience, particularly if one fertilizes. Remember, this is the *bark* we are using, not sapwood and not the bark from deciduous trees. In the proper ratio, bark is an exceptional material for any container mix.

Comments (11)Thanks for replies, guys. Buford, I did see teensy tiny buds on the new ones I got. Only one of my new ones has any left. Also, spring came right about normal here, much to my joy... no more winter! Jacqueline, usually I've got teeny weeny buds by this time of year. My roses always put out the buds at the same time as the new growth. April is rose month here, so consider they have to have time to develop and mature before April. I've had roses for over 20 years now, and wouldn't be asking this question if this was out of the ordinary! I've definitely got patience, trust me. Three acres of garden takes quite a lot of it lol. Seil, would every rose put out nothing but blind shoots? There has been a lot of cloud cover and rain lately. I will give a couple more weeks to see if they do anything else on their own then go ahead and do the short clip. Brittie, that makes me feel better as you are very near me in La Porte. Thanks again guys....See MorePatty W. zone 5a Illinois
