Why are my cucumbers dying? (with photos)
Comments (14)It was said: "Powdery mildew in summer in Louisiana? I think it's bacterial wilt." Because I don't know anything about bacterial wilt, I'll give you that possibility. But please look at the leaves, they are coated with PM. Beyond that, I also saw they are in containers. And I think those comments (above) are right on. But since the plant is essentially gone, yes, I would remove it (not pull it) and look at the roots. The answer may well be there....See MoreShrubs dying, and don't know why
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 MoreID this bug please? [pic]
Comments (10)rhizo, It must be over thirty years since I've been bitten by more than a mosquito. I guess I'm curious to a point and from a distance. [g] Okay, I found this about Bats.... Katydids and Bats Crickets are not the only animals that inadvertently signal to another species. A close cousin of the field cricket, the greener, longer-legged katydid, faces a similar challenge. Instead of attracting the female he bargained for when he launched into full voice, a male katydid may find himself becoming a meal for a bat. A repetitive staccato trill made up of many frequencies proves easy to locate, no matter what species produces it. This is, of course, the purpose of the male katydidÂs trill. But in bat-infested Panama, katydids change their tune. They sing a higher-pitched song, with a narrower frequency range, much harder to locate. They also sing a lot less. In an experimental situation, loud, enthusiastic katydids caged with hungry bats survived less than a minute. Shyer, quieter males lasted more than half an hour before becoming bat bait. But if males must remain quiet to survive, how can they attract Ms. Right? A quiet, infrequent trill can bring a female into the vicinity, perhaps to the same plant. The quieter males then complete their attractive act with a silent dance so enthusiastic they shake the leaf theyÂre standing on. Females detect the dance through the plant, locating the source of both the beautiful voice and the swiveling hips....See Moredoriswk
