Purple coneflowers have Yellow Aster disease
Comments (15)Hi everyone, I am trying to prep my garden and wondering whether I should pull up all of my coneflowers. I didn't know that they had yellow asters until I looked up why coneflowers turn green. I noticed the weird look last fall, but thought, "Hmmm⦠I must have planted an exotic one and didn't remember." Do I really need to pull up all of them NOW or should I wait til they come up to see which are healthy? I have 50% perennials in the garden, much of which are resistant to the aster yellows. The coneflowers and rudbeckias are just the 2 that might be impacted....See Morepropogating a shrub in a potato?
Comments (9)Paul James must be lurking around these Forums. I introduced this subject here about three years ago culled from an unpublished radio broadcast my Dad did back in the early 1940's in which he was detailing some horticultural history. The old time technique was to insert a cutting in a potato (yes, you can use rooting hormone), bury it in a shady spot and keep the potato foliage cut back but still growing. I have done this successfully with easy to root shrubs such as privet. Suspect hydrangea might root well, too. For me the most fun of gardening is the tinkering; the trial and error. The potato rooting experiment is easy to do and some of you might find it interesting....See MoreAll my coneflowers, cup plant and others -- stem rot?
Comments (3)Thanks Dr. Liz. We've not had as much rain here in Dayton as you've had, we seem to be in some kind of rain shadow, but it has been more damp and cool than the summers of the past decade. Delightful, to be sure, but sad that my flowers are nil. I am not too worried for the plants themselves but they look a mite weedy without the flowers. Oh well. I will research organic fungicides, as pulling all affected parts might mean yanking entire fields of flowers....See Morewaratahs - propogation?
Comments (2)I'm no expert on propagation of Waratahs (genus Telopea) but I do know that the best method of propagation is seed for naturally occuring species and then by cutting for hybrid species. You could certainly try propagation of your cuttings but make sure you remove the flower head and leaves so as to direct as much energy as possible to the generation of roots. Good luck! More information of Telopea propagation can be found here: http://www.anbg.gov.au/telopea/index.html http://www.rbgsyd.nsw.gov.au/plant_info/Plants_for_gardens/Growing_waratahs And just as a passing observation related to the beauty of the Waratah flower; it's a crying shame to visit our national parks and see that the rangers have to spray the flowers with blue paint to stop visitors from stealing the flowers and deny the plant the opportunity to develop seed and naturaly propagate. The poor old Waratah is too beautiful for its own good against the personal greed of human nature....See Morediggerdee zone 6 CT
