Crown Gall on Weeping Willow - Help!
Comments (10)I have the same problem with a forsythia. I can only see the galls after all the leaves have dropped. I've been pruning them out for years. The plant has survived and continues to grow though it doesn't flower like it used to. But since it's used as a privacy screen that doesn't matter to me. The disease has yet to spread to other plants and I don't think it's likely to either. I spray my equipment with alcohol in-between cuts and I remove all debris under the shrub and put down fresh mulch after the leaves drop and then again in the early spring. Here's what gall looks like on my forsythia....See MoreCrown Gall, replant in same spot?
Comments (7)If it is gall, there are several schools of thought. Some say don't replant because the bacteria exists in that spot. But, the bacteria exists in MANY places. It is indigenous here in the west, like Oak Root Fungus, but both require the right conditions to be stimulated into active growth. Some say to replace the soil or dig it out, letting it dry thoroughly. There is even a school which suggests sterilizing the soil with a weak bleach solution, then flushing it through the soil with copious water, then letting the whole dry out completely before adding more organics or native soil and replanting. My own thought is, the bacteria is already there. It required the right conditions to establish its symptoms. Whether I replant in that soil or not, the chances are gall will occur. Some roses are much more susceptible to it than others. I've seen it on a number of Flower Carpet and the Meilland landscape roses. The Fairy is highly susceptible as is Francine Austin. Francine often forms galls everywhere it roots in many gardens around these parts. I've experienced gall on own root roses from various nurseries planted in only potting soil in cans. Neither Werner von Blon nor Rabble Rouser have been grown in native soil here, as both were small plants from two different nurseries. Both are canned in potting soil and both have galls. Most of the roses I've grown have no symptoms of it, but I know it's here. I seriously doubt any efforts to prevent it from occurring are going to have much effect, other than to use Galltrol, the antibiotic to control gall outbreaks. I don't week whack around the roses, nor do I dig around their roots. Moles and gophers do a lot of that for me. If a wound is necessary for the gall to enter and begin working its wonders in the plant, then rabbits, squirrels and gophers probably do more than enough to assist it. But, none of the canned plants have experienced those issues, yet they express gall. So, I live with it unless or until it becomes sufficiently serious to inhibit the plant. It's just another of Nature's checks to prevent any one species from becoming dominant. Kim...See MoreThe outcome of my crown gall problem
Comments (2)Thanks Seil, The hole we (not really me) dug is huge, It's probably 30 in. in diameter and also 30 in deep. Better safe than sorry, , , I hope. As I said, I knew nothing of Falstaff. After researching a bit, it seems the best I can hope for is a rather spindly and stingy with blooms plant. But that's okay. I'll just hide it behind a leafier rose. It's worth it, for the beauty of the bloom.. andrea...See MoreMaybe more blooms on Francis Meilland
Comments (11)Thank you Pat and Jim. Pat, I think you would love it! If anyone could get it to bloom, you could, your roses are so prolific. I really do think there is something about the spot I planted mine that has prevented it from blooming more, since Firefighter is in the same bed, and has had similar issues, but they are both improving. Come to think of it, I've been wondering about my Pope John Paul II, which is in that bed too, and blooms okay, but is kind of a runt compared to the ones I've seen in pictures, I love it too, but also wish it was more vigorous....See Moresusan4952
