Yellow spots on leaves

9 years ago

Just discovered this forum so let me first say hi to everyone. I'm hoping someone might be able to help with my problem. A couple of my AVs have developed yellow mottling on the leaves. Do you have any ideas what might be causing it? I'm new to growing AVs and have just wicked and repotted my plants last month. They're all full of buds popping up. I have attached 2 photos below. Besides the yellow spots, one leaf started also getting some brown lesions. Thanks in advance for your replies. ~D

    Thank you Jeff. I did check with Dr. Optimara first and did not see these symptoms. I saw it didn't resemble fertilizer or sun burn, and I don't think it's a water or light issue. This particular plant is a good bloomer whose flowers last a relatively long time. I hope it can be fixed. I have isolated the plant to be safe though now the lighting is less than ideal for it.

    Wow, when I go to that site, I identify 15 different things my plants "might" have! Just kidding!

    When I am unable to determine the cause because so many problems cause similar damage, I start over and go back to the basics. It is often difficult to determine exactly which one or ones of the problems are causing the damage.

    What does the underside of the damaged leaves look like? Have you ever seen any pests on your plants? The pattern of the damage to me looks like it could be pest related. But--it could also be a lot of other things.

    Get a magnifying glass and look your plant over carefully. Look for critters but also look at the damage. Somewhere on the internet I have run across close-up photos of critter damaged AV plant leaves.

    You could also recheck everything, water/wick, light, food. With the recent repot, it could have suffered some minimal leaf damage that is just now showing up. Isolation is a good idea. Were it me, I would leave it in isolation until I determined the problem or if you're sure there are no bugs and everything else is good, wait for new leaves to grow that show no symptoms.

    By the way, since I am a recent survivor of thrip wars, I am paranoid about them. That color bloom is a thrip magnet! Hope thats not your problem.

    Your plants look quite healthy, aside from these small leaf discolorations. In my experience, such minor discoloration is commonly caused by lighting/sun issues ... and/or water droplets being allowed to remain on the leaves.

    I see no other indications of a serious problem, ... though I always caution growers to check with their water providers to see if they use Chloramine in their water processing systems. If so, jugged grocery Spring water is the way to go (as Chloramine is toxic to African VIolets). I can get (Glacier) dispensary water from my local grocers for about 50 cents a gallon. As my municipality has utilized Chloramine (to some degree) since the mid-fifties, switching to dispensed Spring water has made a world of diffence in my success in growing AV's.

    Otherwise, I would follow Jeff's advice and isolate these plants (from any others you may have), ... and see if the problem clears up (as new leaves grow in to replace the discolored ones).

    I am siding with Aegis. Cosmetic damage from some kind of culture issues Aegis listed them. Plant is slightly overpotted - and may be too deep in a pot - do not see it from the side. If you repotted it recently - the spots can be just from handling.

    Aegis, I've been told to use the tap water that's filtered from the Pur water filter. My husband says it takes out practically all the impurities. Has anyone heard that, too, or know otherwise?

    Irina, someone from my extension office also told me this morning that I repotted too deep. Looks like I made that mistake with all my AVs and I'll try to fix after their done blooming.

    The extension office was not able to identify the problem though they did point out that the small new leaves don't have the spots.

    This may be unrelated: When I got home I decided to change out the water and found tiny wiggly things in reservoir of one of these plants that kind of look like larvae. Maybe I should start a new post on that but wonder if it's related to the spots. Wish I could attach a video!

    i really appreciate hearing all your thoughts on this.

    D -

    photographs help! Top - side - and whatever bugs you have.

    You can't see it but they have tiny torpedoed bulb heads. They're different sizes probably at different stages of development. There's peat in the bag but you can see squiggly things lower right corner.

    I could swear they've grown since this morning.

  • 9 years ago

    The good new is, they don't appear to be thrip larvae. I know what those look like.

    We'll have to wait for the experts to weigh in. They look like all the stuff I used to look at in biology class. I never did well in Biology!

    Mosquito larvae come to mind.

  • 9 years ago

    What husband said but he was guessing.

  • 9 years ago

    Mosquito larvae. You have some strange pets...

  • 9 years ago

    Not happy about breeding them in my home. Shouldn't affect the plants though???

  • 9 years ago

    Nope. But I would flush every single one of them down the toilet.

  • 9 years ago

    May have only been one mosquito in the house--but I'm checking every one of my reservoirs tomorrow.

  • 9 years ago

    Yup - and then the whole bunch of them would emerge - and start hounding you and hubby.

  • 9 years ago

    All those larvae -- swarms of mosquitoes in the house! This is the kind of stuff nightmares are made of...

    I would say your bugs are springtails, not mosquitoes or thrips larvae. (Thrips, always plural even if it's just one, larvae live in the soil not reservoirs.) Springtails are very common in reservoirs and are harmless to you and your plants. Ignore them. They won't spread to your living quarters or take up residence in your hair. I would say your spots are culture related-probably water spots. Sunburn usually looks crispier.

    Hi Linda good to hear.

    Just an FYI I'd like to add that around here we're told not to keep standing water around as mosquitoes will lay their eggs in there. It's been a real concern with cases of the Zika virus heading up our way. Usually they refer to the outdoors so l suppose it's unusual in the house.

    In any event, so glad to hear those creepy things are not a concern and even gladder to rid my house of them.

    It's also a relief to hear about the culture thing. It just taught me a lesson that neatness does count when it comes to repotting. Take my time. And handle gently.

    Springtails are inevitable if you grow violets for any length of time. No biggie! Never re-pot when you are in a hurry. Say a few ohms and take some deep breaths....Seriously, I enjoy my re-potting as one of the most relaxing things I do. Take your time, inspect your plant and think about how beautiful violets are. Their variety in blooms and foliage is a wonder of nature.

    Found repotting the standards to be relaxing. But those minis...yipes! For me I found it to be a very stress-inducing experience. Even now I'm finding that they might not exactly be my cup of tea.

    See that? That's a first for any of them! This one's getting ready for a real first show of blooms.

    Not ready to give up. Yes I can grow minis. Yes I can...
