Pests!!/are they killing my plants?! Help

9 years ago

I've had a few rooted cuttings, one hoya and a couple other plants.they were doing great it seemed, then a leaf turns yellow. I check the roots and the stem is hollowed out and there are these tiny almost clear worm-like things! What are they?. How do I get rid of them without harming the roots or plant?

    The clear worms are usually fungus gnat larvae.

    They are in the rotting stem and a few in the soil. What caused fungus gnats? One came that way from eBay but the others?? At the risk of sounding stupid, What is BATS?

    Bayer Tree & Shrub. You can get it at Lowe's or HD. 1 oz per gallon of water. It is, of course, poison so keep away from kids and pets.

    How are your cuttings doing in general?

  • 9 years ago

    Some are doing well I think and some not so well. I lost my lacunosa (forgive my spelling if its wrong) my Eskimo and my obscura..., makes me want to cry!Lisa is struggling.Very stressful.

    My wish is to find a Lisa in the US that already rooted

    Bridgett I finally sent your package. I'll email you the details.

    Usually, with cuttings, the hollowed out stem is caused by rot from too much moisture. Fungus gnat larvae are GREAT decomposers, like most maggots, but they don't always discriminate between live and dead plant tissue. Fungus gnats breed in, and their larvae thrive in, warm, damp potting media. To eliminate them, and rot issues, cut back on misting and watering. Go ahead and treat with Bayer, if you haven't already.

    I am rooting several Lisa cuttings and will send one your way, when the root system is well established. Expect it in a month or so, weather permitting, of course.

    Crossing fingers that the Bayer works for you!

    Aurorawa (8B)first let me say "thank you" but I have a question a little off topic. I know that brown or black roots mean "rot" but what does it mean when they are still cream or white and they are still dead or dying? I have a carnosa and I got about 4yellow leaves overnight. They were green yesterday. So I look at the roots. They look OK but when I touched them I realized a lot were dead can I save the plant? Do I just pot It back up?how should I proceed?no bugs in it by the way

    There is such a thing as dry rot, which could account for the root death in your carnosa.

    How did you come to the conclusion the roots are dead? Were the lowest leaves on the carnosa yellow? Or was the yellowing spread throughout the plant?

    Usually, wet rot causes the leaves closest to the roots to turn yellow at the petioles first, then it progresses to the entire leaf. As this happens, the part nearest the petioles turns black and the leaves and stem will go mushy. Dry rot causes everything to go brown starting with the roots. Nothing is mushy, but because the roots dry up and die, as well as the root stem, the plant yellows and starts declining.

    The fix for both types of rot is the same: take cuttings of healthy, unaffected plant tissue.

    The leaves closest to the bottom were yellowing and falling off still had some green but mostly yellow.so I looked at the roots. Not white but maybe cream in color but when I touched them they were dead .pulling off very easy, stringy, hollow etc.usually I see yellow gradually come but this was overnight.

  • 9 years ago

    I would go ahead and take a cutting or two.

    Don't get discouraged! My first experiences with hoyas involved a lot of rot, death, and pesties!

    Best advice I can give is to keep tweaking your conditions until you find what works for you and YOUR climate!

    This is the second round of yellowing. I lost about 5 leaves now these are next

    Take cuttings asap to save it.

    When I got it it was just 1 looooong vine so do I just cut the whole thing off because the yellow is at the bottom? Also how long should it be to root? Its about 12" .should I make it into several cuttings or just root it as one long cutting?

  • 9 years ago

    You can root it long or cut it up. I would cut it up and root 2 or 3 pieces incase some dont take or they rot.
