split bark on hydrangea and crape myrtles
Comments (8)I checked my crape myrtles today and found some little leaf buds finally starting to come out on one of them (my biggest one) even up high on the branches. I was afraid they might've died back to the ground. Still no growth on the other two. How are yours doing Mary? Both of my oak leaf hydrangeas have growth coming out from the bottom only so far. I think the tops might be dead on those but I'm going to wait awhile before cutting them back just in case. Is your 'Sun Goddess' showing any life yet? Nancy - Are your crape myrtles leafing out yet? The first year after I planted mine, it died back almost to the ground and didn't start growing again until the very end of May. I had planned to dig it up because I thought it was dead. It got a late start but then grew quickly and still bloomed great that summer....See MoreCrape Myrtle Scale Pictures
Comments (5)They are a scale specific to crape myrtles. First seen in Texas over a decade ago, and slowly spreading northward. Crape Myrtle Scale was first seen in OK in Ardmore in 2012. It made the news here around that time, but I haven't seen it mentioned locally since then. Let me find and link maryl's other thread about it. I believe neem oil isn't effective, but I don't remember if I read that somewhere, or if maryl told me that, or if someone else told me that. Since it is relatively new, horticulturalists and ag researchers are still working on finding an effective control. Obviously it is better to catch it early, but hindsight is 20-20 and once it spreads, a person is really stuck between a rock and a hard place. Since maryl mentioned the infestation on her plants, I now check mine daily....not that I am paranoid or anything. Original Post on Crape Myrtle Scale I almost never see scale here on anything, even when a scale outbreak of a certain kind (like redbud scale, for example) seems commonplace across Oklahoma. I don't know if we have some sort of beneficial insect that feeds on scale here, or what....See MoreDisease id on crapemyrtles, please help
Comments (4)Crape myrtle bark scale. Believed to have arrived in the Dallas area from Asia around 2004 and has been spreading rapidly. We're just a few miles from the earliest reported sighting and have been living with it for several years on our eight crapes. Initial infestations were heavy until the ants found them.... now not so bad. We don't even bother to treat them anymore since there's not much noticeable sooty mold as long as the ants keep the scale sparse. It doesn't seem to harm healthy trees and with all the CMs in our neighborhood, it's unlikely we'll ever be rid of them. Too bad for such an otherwise trouble-free tree....See MoreMay 2019, Week 4
Comments (40)Nancy, I saw where they were advising some folks in Wagoner to evacuate, and that kind of surprised me, but then when you look at the rainfall map for the month of May, maybe the big surprise is that the whole northeastern quarter of OK isn't evacuated already. Yes, there's so many good people doing so many things to help the people, livestock, pets, wildlife, etc. It is touching....like fire stations offering their use of their 1 or 2 showers to people whose homes have lost power and/or water....and people who are just showing up with cases of bottled water, figuring somebody needs it for drinking water. Shelters popping up, volunteers coming to staff them, restaurants feeding the first responders, and on and on and on. That's the Oklahoma Standard, isn't it? Like you, we're on high ground, so while the Red River is on three sides of us, it never could flood enough to reach us. I had a few doubts in 2015 when we got 80" of rainfall and the river seriously flooded (including washing away two homes not that far from us--but at a much lower elevation--but water never got close to us. We could drive a couple of miles and sit in the parking lot of the McGeehee Catfish Restaurant and watch the incredibly high water go by, but then we drove back uphill to get back home. Everyone said the creeks might back up because they couldn't drain into the river, but they really didn't. They ran high after heavy rainfall, but they always do, and even then, the water would have had to rise 12-15' to make it up the hill to our yard. There was never any chance of that happening. Our road never has flooded at the creek, but there's been flooding to our south and to our north, so we might temporarily be trapped at home for merely a few hours. We almost bought riverside land at a much lower elevation, and I am so grateful we didn't---although we would have had incredible neighbors. (We also have incredibly wonderful neighbors here.) I paint that way....forgetting myself and ending up with a new set of painting clothes too. I don't think it is that I don't know I'll get paint on me, just that in my excitement about getting it done, I forget to go put on clothes that already are dotted with paint. Thanks for sharing the story about Russ. I'm glad he had the chance to get to know his father better. Jennifer, First, congrats on Ethan's high school graduation! That's such a monumental point in a young adult's life (and in the parents' lives as well). Everything eats seedlings. Caterpillars, snails, slugs, flea beetles, army worms, pill bugs and sow bugs (they are decomposers but I find them eating plenty of green plants as well), and I could go on and on and on. Most plants outgrow it, but the brassica family plants need to be treated or the cabbage loopers and cabbage worms will destroy them. There's just too many of the little caterpillars and they munch until they become big caterpillars. Bt 'kurstaki' is the answer. Many of the pests that will eat kale, broccoli, cabbage and cauliflower really, really prefer collard greens or mustard greens, so often I grow those on the edge of the garden so the pests will flock to them and not bother my other crops so much. That works pretty well. The non-organic gardeners spray with synthetic pesticides. I have friends who do that. Their plants always look perfect. They use stuff like Bug-B-Gone and Liquid Sevin, and in the olden days used all sorts of heavy-duty stuff like organophosphates like diazinon and malathion. I'd probably give up gardening before I'd ever use those, but using them doesn't bother some people. Guess what is missing from their gardens though? Lady bugs, green lacewings, butterflies, dragonflies, hover flies, flower flies, bees, and often....anything that anyone would consider a pollinator, so they end up having pollination issues. The organic gardeners often spray with organic broad-spectrum pesticides too. I'm not going to fault people for doing that because it is their garden and their choice, but I just do not like spraying a broad spectrum pesticide all over everything. I feel like it isn't worth (to me) the risk of running off or killing all the beneficial insects. Still, I'll never say that I absolutely, positively never would use these products because some day something might happen that pushes me to that point. There are many broad-spectrum organic pesticides available---Spinosad, Neem, Organocide (soybean extract, fish oil and sesame oil), PyGanic (pyrethrins, so can be deadly to felines), Safer Insecticidal Soap (Potassium Salts of Fatty Acids), Safer Tomato and Vegetable Spray (Potassium Salts of Fatty Acids + botanical pyrethrins), Take Down spray (Pyrethrins and canola oil), Hot Pepper Wax (more of a repellent) and Garlic Barrier (also a repellent), Zero Tolerance (herbal oils like rosemary, thyme, cinnamon and other oils), and Beauveria Bassiana (when you need to bring in the big guns---it is a mycoinsecticide that is a fungus in a Liquid Emulsifiable Suspension used to kill soft bodied insects and a few hard-bodies ones as well). I bought Beauveria bassiana last year when I felt like the grasshoppers were winning the war over who was going to harvest from the garden, but then they disappeared (I think birds were eating them) and I never used it. I probably wouldn't have sprayed it on my garden plants but was going to spray it in a 10-12' wide band all around the exterior of the garden fence in the hopes that the grasshoppers would make contact with it there and would get sick and die. Every time that I think that I could and would and will and am going to use a broad-spectrum pesticide to combat some horrible thing in my garden (hmmm....leaf footed bugs or squash bugs or stink bugs, for example), I think about all the living creatures in my garden that I like seeing there, and I just cannot do it. I guess I am a total failure as an organic pesticide user because I cannot use the above products. I will use some narrow-spectrum ones---like sometimes Bt on the brassicas or Semaspore for grasshoppers (it is a bait) or Slug-Go/Slug-Go Plus (a life saver when you have a heavily-mulched garden full of pill bugs and sow bugs), but cannot bring myself to use the broad-spectrum ones. If holes in your kale or cabbage or whatever do bother you that much, then why not find the right product and spray them? Bt should take care of most. Little tiny grasshoppers are just now beginning to hatch out here, though I have not yet seen that many, and they eat holes in everything. I don't think I'm seeing enough of them to make me worry though. Not yet. I usually have a bottle of Take Down spray in my shed so I can spray it directly on hard to catch things like leaf-footed bugs, but I've been out for a couple of years and just haven't bought another bottle yet. It is your garden. If the thought of holes in things bother you, spray with whatever pesticide you're comfortable using. I've just gotten away from doing that and hardly notice the holes in leaves any more. dbarron, Ha! I have had to water my containers the last 4 days. That's what we get for having a combination of strong winds all day long and temperatures in the upper 80s, sunshine (finally) and no rain (oddly). I won't complain and say the rain is missing us, but we aren't getting anything close to what everyone else is getting and May is barely above average rainfall at all compared to other months over the last year. Our ground is starting to dry up some (woo hoo!) and there's no rain in our forecast until Tuesday. I'm glad you're safe from flooding. That's one less thing to worry about anyhow. Eileen, With regards to your pepper seedlings, yes, birds will do that sometimes. Usually it is mockingbirds and they do it only to tomatoes and peppers. I have no idea why. They don't eat them. They just cut them off and leave them lying on the ground. It could be something else---there are some climbing cutworms that will climb a plant stem a couple of inches and then cut it off. I have no idea why. They always seem worse in wet years. I hope your house will be okay. There are some limited 100-year flood zones directly alongside some of the creeks in our neighborhood, but I've only ever seen the creek come up into the yard of one house on our street, and it sits quite a bit lower than us---I think they are actually in the 100-year flood plain while we're well above it. Of course, we had the good sense to build on the highest point of our land, not down in a low area beside the creek, and that helps too. Out closest neighbor to the north put a mobile home way back in the woods right beside the creek. Perhaps they should have taken a clue from the fact that the old farmhouse on that property was built on its highest point of ground but apparently they did not. Still, that house didn't flood in 2015 either. I am sure that if I lived up there in your general area, I'd be feeling anxious about all the rain too. The images of all that water everywhere is mind-boggling. So is the forecast. Rain keeps falling and falling and falling, mostly over the watersheds that can least handle more rain. I feel pretty good about the Red River near us and Lake Texoma right now. They've been releasing water from Texoma for several weeks now, and it is to the point where they're finally releasing water from it faster then new inflow is coming in, so the lake held steady yesterday and should be dropping beginning today. The Red River is high and running fast, and absolutely wall-to-wall (i.e. bank to bank is full) which is not all that common here, where it often is so low you can pretty much walk across it---and, sometimes, in the summer you can walk across it without touching water, but as of this morning, it still was within its banks. We had the unexpected pleasure of a weekend with our oldest granddaughter, so today was kid stuff--shopping for summer clothes, going to the playground, to the movies (Aladdin) and then home for pizza night, playing games and watching some TV. We tortured her by forcing her to watch two episodes of Gunsmoke (in black and white) with us. She thought it was funny---especially because it was in black and white. One guest star was Kurt Russell, playing a kid about 12-13 years old, and she asked me if he was Elvis. I told her no, but that later on, after he grew up, Kurt Russell played Elvis in a movie about his life. She thought it was cool that she picked up on his resemblance to The King. Everyone has gone to bed now except me and one cat, and she's lying here beside me trying to sleep. The house is quiet. It is a nice time to reflect, and Nancy's beautiful description of how Russ reconnected with his dad has me thinking about cancer. A few weeks ago we lost one of our neighbors to stage 4 cancer of the nervous system. He went so quickly after his diagnosis that it was mind-blowing. Today, we found out that a family member of his to whom we are quite close was diagnosed with stage four cancer in his spine. This is such devastating news. He soon will begin a very long chemo regimen. It is hard to understand, sometimes, why some families get hit again and again by diseases like cancer. I didn't work in the garden today, but expect to be able to do a little work out there tomorrow afternoon, and possibly on Monday. It has been so wet that I've largely stayed out of there, except to water stuff in containers. I did a little deadheading and weeding the other day, but not nearly enough. I am keeping up on harvesting. We are very far behind on mowing. Neil Sperry had a great reminder in his newsletter this week that it is chigger time. I'm glad he reminded me. I've been walking through the taller grass in the yard without insect repellent on (I hate spraying it on my skin!) and am sort of surprised the chiggers haven't gotten me already. Am I the only one wondering what happens to the insects in the heavily flooded areas? Like the areas along the Arkansas River where floodwaters are 3 or 4 or 5' deep in neighborhoods, cities and homes? Do the insects get swept away in the floodwaters? Do they die? Do they fly away or crawl up high into trees and survive? What about the earthworms? How about the crawdads? Did they get enough warning to flee to higher ground like they did here in 2015? I mean, I have no idea what does or doesn't survive in this sort of flooding. I do know that mosquitoes become a huge problem even before all the water recedes, but what about everything else? It is something to ponder, is it not? Dawn...See MoreRelated Professionals
