If you take a closer look, you'd see that my dahlia duet prodocues two different kinds of flowers. The one being red.. and the other being red with white tips. Is this normal? and also, the very same dahlia plant has been having a layer of mold or soemthing on the top part of its leaves lately. I could rub it away with my fingernails. I was just wondering if it's normal.
When a plant of any kind is a grafted plant (which your Dahlia probably is), there is always a chance that there will be flowers from the mother plant (aka root stock) and from the plant grafted to it, resulting in two, sometimes three different colors. I had a grafted climbing rose several years ago, that was red when I bought it. After a really hard and long spell of ice storms and single digit temps, the rose died back down to the root stock. Next season, the root stock put out stems and resulted in white blooms while the grafted part also grew and bore red blooms. The next year there were white, red and pink blooms. After a couple more years the red stock prevailed and it has been red since then.
Hello Hyacinth - lovely to have you here with us. It sounds as though your dahliaa are suffering from powdery mildew. Here are a couple of websites that you may find interesting on the subject. :-D http://plantclinic.cornell.edu/FactShee ... owdery.htm http://ohioline.osu.edu/hyg-fact/3000/3047.html
Way to go Eileen! I was going to post about powdery mildew. Im having another bout of it on two of my roses.
And also... I was wondering if I have to cut mydahlia down when frost comes. Any chance of them surviving if i leave the tubers outside? I wouldn't want to cut down mysweet dahlia
This website tells you all about what to do with dahlia tubers during the winter Hyacinth. I hope you find it of some use. :-D http://www.thegardenhelper.com/dahlia.html
I've always thought that Dahlias were used to cold climate...like tulips and the like. Guess i was mistaken, eh?
Your dahlia is very pretty even if it does have different colors. I only tried growing them once. I planted them in the spring and waited for them to grow. That was 3 years ago - they never grew.
