Knock Out roses vs Fairy Roses?
Comments (8)Originally, the "Fairy Roses" were dwarf (two to sixteen inches) rose bushes with single or double blooms, cultivated in the 1800's. They are/were dwarf or miniature Chinas and are probably virtually extinct now. The fairy rose available today is a Polyantha Shrub Rose which is usually a smaller than average rose bush, growing to about three feet. The pros and cons between Polyantha Shrubs and Knock Outs are pretty much dependent on what you like, want to take care of, and how much you want to see the same thing (particularly in the case of the Knock Outs) in almost every garden from Maine to California and everywhere in between....See MoreKnock out Roses on sale at 'Roses'
Comments (2)HD plants usually do not last for me. I have brought plants from Roses this year (Azaleas) and they were very competively priced and are doing well. I vouch for Roses as well...See Morekill poison ivy that wraps around KnockOut Rose
Comments (13)Roses can absorb RoundUp from the soil i.e. overspray is not the only way glyphosate can reach your roses. The Round-Up can leave the roots of a treated weed, pass through the soil, and be picked up by the roots of nearby rose bushes. http://link.springer.com/article/10.1007/s11104-007-9387-1# AND http://www.sciencedirect.com/science/article/pii/S116103010900063X Also, the glyphosate could remain bound in the soil for long time periods. "Glyphosate [(N-(phosphonomethyl)glycine)] is a widely used herbicide and it is known to compete for the same sorption sites in soil as phosphorus. Persistence and losses of glyphosate were monitored in a field with low phosphorus status and possible correlation between glyphosate and phosphorus leaching losses was studied. Glyphosate and its metabolite AMPA (aminomethyl phosphoric acid) residues in soil samples were analyzed after a single application in autumn. Twenty months after the application the residues of glyphosate and AMPA in the topsoil (0�25 cm) corresponded to 19% and 48%, respectively, of the applied amount of glyphosate, and traces of glyphosate and AMPA residues were detected in deeper soil layers (below 35 cm). These results indicate rather long persistence for glyphosate in boreal soils." http://www.springerlink.com/content/w1461w60366lk018/ Then, when you add fertilizer with P; the glyphosate could be released. "The results suggest that re-mobilization of glyphosate may represent an additional transfer pathway for glyphosate to non-target plants which is strongly influenced by soil characteristics such as P fixation potential, content of plant-available iron, pH, cation exchange capacity, sand content and soil organic matter." http://www.springerlink.com/content/t7h6601566432076/...See Morelinks to rose care articles mainly about Knock Out roses
