Rose Rosette vs Roundup - 1 yr later ? what to do
Comments (20)Michaelg, my weed and feed question was a follow up to your 40 years of Round-Up use statement. I cannot remember when a significant number of gardeners started using Round-Up nor when a significant number of homeowners started using Weed and Feed type products. I was hopeing that since you knew about Round-Up use you also knew about Weed and Feed use (time wise). It seems that most people have at most a few cases a year. Why did you lose so many roses? Have you ever posted an in detail explanation of what you observed, when, and what steps you took, when? I know that you stated that you used Round-Up once on the roses. Did you use Round-up on anything else? Did you observe or ask the neighbors, whether they were using Round-Up? Did you use a magnifying glass and observe the mites? Also, how did you rule things such as a herbicide contaminated mulch batch. The last may sound far fetched but I have posted news articles about it happening and I did have bad mulch happen to me one season (I had posted it here when it happened. I immediately removed the mulch and watered heavily.) Back to your statement: "So I think it is wise to assume that fat, thorny overgrowth is RRD." H.Kuska comment. I still would like to see pictures of what you mean. Earlier I posed that Round-Up could result in "Particulary, please notice they include: "Strange looking, thickened growth, often dark red or purple in color"." It would appear that "thorny" is the only property that could not be caused by Round-Up in your model. On my web page I state the following: "I am hesitant to include the "excessive growth of thorns" rule as it may only apply to exclude damage from certain types of herbicides and not others with different modes of action. Also. often healthy young growth can have closely spaced needle like thorns which are not present in older canes. The opposite (no thorns, no RRD) is also NOT a dependable diagnostic that the cause is not RRV. Ann Peck (see E-book link at the bottom of this article) points out: "Hyper thorniness is not a dependable indication of RRD, it does alert rosarians to be vigilant. It appears on some HTs, but sick OGRs and roses related to 'R. multiflora' may have thorns no denser than ususal. Further confusing diagnoses, many classes of old garden roses are extremely thorny and no one could look at a sick rugosa, damask, or spinossissima and declare it�s hyper thorniness to be aberrant. Likewise basal breaks on some healthy HTs appear thornier closer to the bud union, but become less thorny with increasing healthy growth. This year, I have also seen a characteristic of some roses from cold hardy breeding programs to have denser thorns near the base; these roses have a built in rodent deterrent that I had not noticed until a question from New Brunswick about the possibility of RRD in that part of Canada.""...See MoreNew Dawn rose not doing so good.
Comments (14)The yellow leaves could be from last year, just pull them off. I wouldn't worry about fungus diseases on ND--she will get a few spots but shouldn't be harmed. I would place some containers around the sprinkler, like cat food cans, and measure how much water comes out per application. You need at least 1/2 inch to penetrate to any depth. People usually give 3/4 or 1 inch at a time. You might need to change the system to put out more water, less often. Most plants can use 3/4 inch per week in cool weather or 1 inch in warm weather, including rain. If you've had lots of rain, I was probably wrong about thinking it was wilted. Are the flower necks stiff in the heat of the day? Possibly the frequent sprinkling contributed to the balling of flowers--if they are shaded in the morning and stayed wet a few hours....See MoreHow can you encourage vigorous growth?
Comments (25)Vigorous growth- you eliminate root competition. Who needs a damn lawn, how about mulch from sidewalk to doorstep? You mulch over everything, get rid of that damn grass, and grow a tree that was designed for that soil. You don't worry about fertilizer, the tree is already in it's optimum environment. My main man here in town, Howard, in twenty-five years has grown his ginkgo tree to the same size as the largest one in Dallas which is seventy-five years old. I can post a link of photos of both trees if anyone doubts it...He did it with Garrett juice, and never once put any synthetic ferilizer down...it's a soil food and it helps develop ROOTS... When I look at a tree, and Howard tought me this, my focus is totally on root development, the above ground part of the tree is a lot less relevant...roots vs. top growth, it's the classic tale of the chicken and the egg...and for the last time, the chicken comes from the egg...the tree comes from the roots... in fact, the very first chicken hatched from the egg of a mutant lizard...the egg came first, the chicken later......See MorePics of 1 yr. old plummies grown under lights in winter
Comments (26)How long? About 3-4 years. I can't remember. I let this ensete die because it was so big. I didn't dare take it outside during the summer months because the wind would break it off. Because of this, I couldn't flush the soil with water to flush out salt build up from fertilizers and other stuff in my hard water, so it eventually went down hill. I just put it outside to finish dying a week ago. However my other 3 that I put outside during Summer are down stairs in my unlit, unheated basement room in dormancy. In the Fall, I cut them down to 5-6' stumps, repot them in 15 gallon nursery pots, and stick them in the basement till next Spring. They have large thick "trunks". I do this every year and they come back to full beauty in the Summer....See Moredan_keil_cr Keil
