fescue lawn woes
Comments (3)Watering daily for 30 minutes to an hour is probably drowning your grass. It's also probably contributing to chlorosis. Soils in the intermountain west tend to be alkaline, so chlorosis can be a problem. Over watering can exasperate the problem. I wouldn't apply Ironite. It's not likely to help. You've probably got enough iron in your soil. You grass just can't make use of it. Adding more iron your grass can't use won't help. Stop watering so often. Water deeply and infrequently. What kind of soil do you have? If it's really sandy, you may need to water twice a week. If it's clay, you should be able to get by with watering once a week. The key is to apply an inch a week and to water only when it's needed. You should also add as much organic matter as is practical. If nothing else, stop at Starbucks on your way home and ask for their grounds for gardens. Since you're in eastern NM, you may be able to get greensand at a reasonable cost. I've never seen it in Utah, but it's cheap and plentiful in Texas. It's supposed to supply iron in a form that is usable by grass. If you can't find greensand, check to see if the WalMart and/or Sams clubs carry Revive. Its main purpose is as a surfactant/wetting agent, but it also has sequestering and chelating agents in it, and it has some chelated iron, as well. The iron in ironite can't be used by your grass, but chelated iron can. The Revive at WalMart usesw a hose end sprayer. The Revive at Sams is sprayed on dehydrated poultry manure (so it also acts as an organic fertilizer)....See Morecrimson barberry woes
Comments (8)Hi GirlzinOK, Welcome to the Oklahoma Forum and I hope we'll hear from you often! : ) I have been gardening all my life--almost 50 years--and have NEVER had toads burrow in soil enough to kill a plant, so I am shocked that this has happened to you. Toads do like to burrow down in loose, cool soil to protect themselves from both heat and predators, so that might be what they were doing. And, I suppose there is a possibility that you had a major infestation of some kind of insects in the soil that the toads might have been trying to get to in order to eat the pests. Still, toads are a gardener's friend because they eat tons and tons of bugs, so pleae don't harm them. I am not convinced that the burrowing of the toads killed your junipers OR that they burrowing would hurt the barberries. I've had armadillos and skunks dig large, substantial burrows that a full-grown cat could have fit into and even a large burrow that size did not kill the junipers. Usually, when plants in a bed are struggling....and perhaps dying or at least looking like they are trying to die, it is most often a physiological problems like poorly draining soil, etc. So, let's try to analyze what might be going on with your plants in that particular bed. 1. Is your soil well-draining? If it is, even after a heavy rain, you would not have standing water on the soil surface for a prolonged period of time--maybe for an hour or so, but not much more than that. If your soil is slow-draining, though, you might have water stand in the bed for a day or two or three after a heavy rain. Usually, junipers CAN handle quite a lot of standing water, but some parts of Oklahoma have had wetter-than-usual years in both 2007 and 2008 and that can lead to plant death. 2.) Can you describe HOW your junipers died. Did they decline by showing browning of the foliage first and then dropping foilage? Did they die one limb at a time or did the whole plant die at once? Could you tell that the dead foliage was starting down low to the ground and moving up, or perhaps the opposite, that the upper branches died first and then the lower ones died later? Did you observe any insects on the plants? Sometimes spider mites are a problem on junipes. 3.) Grubs can be harmful, but some of them are the larval form of beneficial insects too. If you are familiar with the grub worms that eventually turn into Japanese Beetles or June Bugs, are those what you had? If so, those might have been part of the problem, but it is hard to say. I know they can be very destructive to grass roots, but I'm not sure they chew on shrub roots. 4.) Your usage of the broad-spectrum landscape and garden fungicide by Fertilome does concern me and may be the problem. If you still have the Fertilome bottle, read the label and see if the active anti-fungal ingredient is Daconil (Chlorathalonil). If so, there should be a warning label on the bottle telling you not to spray in hot and sunny weather. Why? Because Chlorathalonil and other similar fungicides can burn and kill plant foliage at temperatures over 80 degrees. (I used to say it occurred at temperatures over 90 degrees, but in our climate it seems to cause damage at "only" 80 degrees or so.) Because I have had these kinds of foliar sprays damage plants (and, yes, even kill them), I never spray ANY thing chemical on my foliage at temps over 90, and very, very rarely at temps over 80. The types of sprays that can cause damage in our hot temperatures include fungicides, summerweight horticultural oils, neem oil, organic OR checmical soap sprays, hot pepper waxes or sprays, garlic tea sprays (if very strong), etc. The types of sprays that do not cause damage (or, at least, that I never have seen cause damage in our landscape) include compost tea, manure tea, Garrett Juice, Bt sprays or Spinosad sprays. Sometimes, if you spray a fungicide on plant foliage at night or on a cloudy day, you will think that the plants were not damaged. But, you often will not see the damage begin to appear until a couple of days after you sprayed, and it can take a week or more for the full scope of the damage to become apparent. Usually, if the fungicide has burnt the foliage, the plant has about a 50-50 chance of recovery, but it can take quite a while. 5.) Another possibility is that you might have used a weed and feed product in a lawn area near your bed. If so, there is a chance that the fertilizer spreader threw some of that weed-and-feed up into the bed and the broad-leafed weedkiller is doing its job and killing the plants. A lot of people use weed and feed products near trees and shrubs because they do not understand that the broadleaf weedkiller is supposed to kill everything but grass. 6) The last possibility I can think of is that somebody somewhere, and not necessarily you or anyone else on your property, used a glyphosate weedkiller like Round-Up and it drifted into your yard and landed on your plants. This may sound far-fetched, but it happens all the time. On a windy day, Round-up and similar glyposate-type products can drift in the air for up to a mile from where they were sprayed. I've seen it happen here in our yard.....where I knew a neighbor had a field or fenceline sprayed, and a couple of days later I noticed I had glyphosate damage even though the area sprayed was hundreds and hundreds of feet from my garden. 7) Finally, sometimes the best way to figure out if something underground killed your plant is to dig up the dead plant and look at the roots. Some things to look for would include: a) Were the roots girdled? Girdling can occur if a plant stays in a container for a long time and the roots begin to grow in a circular pattern around the container. Then, when the plants are put in the ground, if you don't pull those roots apart and try to get them to spread out in different directions, the girdling-type growth continues and the plant literally chokes itself to death. b) Were the plants planted too deeply in the ground? Both trees and shrubs need to be planted so that the flare of the plant's main trunk is above ground and not buried. Planting the root flare too deeply can weaken and even kill a plant. c) Do the roots show evidence of root knot nematodes or any other nematode? If so, instead of having normal roots, you will see mis-shapen roots that have abnormal bulges and knots. d) Are the roots thin and does it seem like they part of the roots have rotted, been eaten or otherwise "gone away". Such damage could indicate too much moisture (if they rotted), animal or grub damage (if they've been eaten) or nematode damage (knots and bulges). There's a lot that can go wrong with plants, and I've tried to list everything that "could have" happened to your plants. Without seeing them, though, and not having watched them decline as you have, it is hard for me to guess long-distance what might have happened to them. I have both junipers and barberries and have never seen anything really bother them. So, think about what I wrote and let me know what you think is the most likely cause of your plant's problems. We can discuss it further, and other folks can share their ideas, and maybe if we all put our brains together, we can figure it out. Good luck, Dawn...See MoreRookie Needs Help with Western WA/PNW Lawn
Comments (42)4/22/2017 Update It's been more than a month since I started. Mid-March this is what I did to kick start my lawn rehabilitation project: dethatched aerated pulled a few weeds out overseeded with a rye/fescue mix put down 1/4-1/3" of top dressing put down alfalfa meal Front Lawn Color is improving. The lawn is greening up at different rates, almost following the strips of sod that were laid down when the lawn was put down last year. Still patchy in in areas, certainly more than the backyard. Lawn lacks that thick, healthy look. Not sure if the seed I bought was good, if I have not waited long enough or if the birds ate it all. Plenty of rain the last 30 days. Lawn seems to be draining better and is not as boggy. Very few weeds, I pulled maybe 2-3 in this area. White flecks in the pictures are cherry blossom petals. This is probably the best part of the front lawn. Really greened-up well and is very thick and healthy looking. You can see how different strips of original sod are greening at different rates. Backyard Color has improved here too, better than front yard. Still patchy in an area that is typically shady. Seed seemed to take better here and I see lots of new grass sprouting up. Drainage seems to have improved but that's only after 1 month of observation. More weeds in this area, pulled perhaps 10-15 by hand. Questions Aside from cutting and weeding, anything I should be doing at this time? The patchy areas - reseed those or just be more patient?...See MoreRed Bed Woes and Worries
Comments (16)Fall is always the time...You have given me a couple of plants that I could not find, and you know that I give them away, so we will plan for fall. Bullfrog Kisses is in its creep year here. It did a lot better than last year. My DH and I have been talking. (He grew up ion a farm) He has never particularly cared much for the daylilies, but this year, they have been so tall and high above the foiage with a few exceptions (always) that he has really been enthusiastic about them and talked about how beautiful they are. My health was not good for part of the year. I had done my mulching, and we got good rain, plus I put the sprinkler on them for hours when we hit a dry spell, but I did not fertilize at all, not even the Fish emulsion or the alfalfa meal, much less systemics. We are wondering if maybe the plants put their energy in blooms rater than so much foliage this year. I will get a soil testing device and check much better for needs than before because this has been a fun year and it would be wonderful to see it again. I have a Petit coming that I hope to see do well, Journey of Magic, and one of Nichols' Smooth Talker...neither one is red:)! ka...See MoreWestCoast Hopeful
