Small white bugs, fast crawlers in soil, please help ID...
Comments (18)Ok, please do not try this without checking it out first. Here is my story. I had this problem more then once. The first time I got these crawly threadlike things in my soil (ie. Last summer), I ended up throwing out my Thanksgiving Cactus. So last November, I purchased a few more Thanksgiving Cactus from the supermarket. I noticed those pesky tiny fruit flies/knats flying around my plants. ( they usually lay their eggs in the soil ) Well that was it! I mixed a combo of rubbing alcohol and water and sprayed the surface of the dirt on my newly purchased plants really well. I have knat/fruit fly traps all over...ie.. Near each plant. For the first time since the Fall, I recently saw the first little bugger and put out my traps. I may do my alcohol/ water spray again. But this is risky. It did not kill my plants, but it can kill them if you overdo this. Proceed at your own risk. Best to try to control this problem. I do not think you can completely avoid it if you have live plants in the home. They LOVE organic soil and there may be unhatched eggs in the organic soil you buy at the garden center to transplant your thanksgiving cactus into a new pot in the Spring. So far I have NOT transplanted anything. Nor have I fertilized anything. These tiny fruit flies/knats come in through screens or with your groceries/fruit that you buy at your local supermarket. They can even come up out of the drain in your sink! I have added photos of these traps. They work well so far for me. You can purchase them at Home Depot or True Value Hardware....See MoreArticle- Why Honey Bees Are Dying
Comments (41)""Hence there is a clear potential mechanism for these pesticides to damage the first line of defence that insects have against disease. Again it seems clear that insecticides are linked to sickness in bees and impairment to pollination services."" The possibility fits in with what has already been discovered about the harmful effects of neonicotinoids ��" in that bees treated with imidacloprid, which is Bayer's biggest-selling insecticide worth ã500m a year in sales to the company ��" are far more susceptible to disease, even at microscopic doses. This has been shown by two independent studies carried out in the past two years."

Comments (10)in FL .... i presume sand soil ???? sand covered in rock ... against a white wall .. i am guessing you cooked the soil they are in ... not to mention the cement walkway and driveway ... which retain heat.. deep into the night allowing no recovery period .... improper watering since you cant tell what is going on under the rock .. ... and relying on rain ..... without verifying is risky .... and baked them with reflected light.. and you may have burned the roots with the fert stake... depending on how that was done ... then sprayed chemicals on seriously stressed leaves ... burning them off.... never fertilize a recent transplant.. and dont waste your money on fertilizer stakes ... total and completely useless ... i really dont think.. there is much here to save ... unless you are willing to wait until spring.. and see how they flush out ... but i dont know if i could look at this.. all winter long.. right out my front door ... if they were new plantings... perhaps they can be replaced under warranty .. BTW .... are they new transplants.. or perhaps.. the stone and the mulch lawn was reworked???? .. significantly affecting their microculture ???? ken...See MoreWhy are my beautiful mimosa trees dying?
Comments (53)@scarediecats,. I found this on the web. I live in a neighboring state, Ohio, and thought I'd look up about my sister beautiful mimosa. (Bark is falling off) enjoy . Native to Iran and China, mimosa (Albizia julibrissin) was first introduced in the United States in the 1780s. Since then, the tree has spread throughout warm, mild regions. In fact, in some places, it is regarded as a weed because the seeds prolifically self-sow. Mimosa doesn't grow well in northern climates, but is well-adapted to mild coastal zones. Cold injuries, though not impossible, are rare here. Cold Injury Hardy in U.S. Department of Agriculture plant hardiness zones 6 through 9, mimosa can tolerate more cold than many trees growing in Mediterranean climates. In fact, cold injury is rare in these regions. However, a sudden, prolonged freeze can cause damage. Twigs and branches turn brown and die back. In extreme cases, the entire tree might die back. Occasionally, the trees' trunks develop cracks, caused by alternating periods of cold and warm temperatures. Sunscald occurs when the harsh winter sun damages the bark of young trees, causing brown or sunken patches on the trunk. These problems are rare in mimosas planted in mild climates. Prevention and Treatment Although you can't prevent frost damage in all cases, a few precautions can minimize the risk. Trees stressed by drought, poor soil or disease are more vulnerable to frost injury. Proper growing conditions can help trees weather cold temperatures. Growing trees in a protected area near a house or other trees can also help. Mimosa trees should never be fertilized in late summer. Fertilizing encourages new growth, prone to frost damage. If a tree does sustain injury, the best course is to prune back the branches to remove damage. Dead branches can be identified in one of two ways. Branches that fail to produce new growth in the spring are likely dead. Live branches will have soft, green material if you scrape away a bit of the bark. but dead branches are hard and brown. Make clean cuts one-quarter inch above an outward-facing bud to encourage new growth. Disease Frost damage is rare in coastal regions. Disease is the more likely culprit of injury or death to the mimosa tree. One disease, in particular, fusarium wilt, commonly infects mimosas. Yellowing leaves or early defoliation is the first symptom. As the disease progresses, the bark cracks and branches die back. Sometimes, the tree oozes a foul-smelling white or yellow foam. Eventually, the entire tree perishes. Unfortunately, no cure is available for this lethal disease, but prompt removal can prevent its spread. Distinguishing Between Disease and Cold Injury Because treatments vary, depending on the cause of the injury, it's important to distinguish between frost and disease damage. Frost damage occurs suddenly after a cold snap, while damage from disease usually progresses over several months or even years. Symptoms from frost damage occur primarily in the winter; disease damage is often most evident in the summer and fall....See Moredoriswk
