    Default Too darn damp around here!

    I noticed a few leaves on some orchids turning yellow. 2 different plants. One I had just bought and repotted. When I checked it out, I saw what I am pretty sure is mold. It looks like long thick strings of spider web. It goes all the way inside. I repotted it in a large orchid mix because spagh stays too moist for too long. This orchid mix seems to dry out faster which seems good right now.
    It was in a plastic pot with small holes on the bottom and then inside a clay pot. I wonder if it just wasn't getting enough air circulation inside it? The mold went all the way into the mix.
    I'm not sure what I can do differently since I can't control the weather and it's been SO wet and dark lately.
    I'm thinking about not watering at all during this very damp time....
    Should I put some holes in the small plastic pot the moldy Phal is in and leave it out of the clay pot to get lots more air?

    My other orchid with yellow leaves that are surprising me doesn't seem to have mold..... I think I'm getting into the "begginer's luck is over" stage and now I will have to start taking blame for not having the correct growing conditions.........

    I think you have the answer not enough air . I would not put it in the outside pot , if you have a sodering iron add larger holes to the bottom of the plastic pot .
    It has been wet here too , on the wet gloomy days I don't water anything not even the mounted or Vandas . If you have some Physan it would work to get rid of the mold . Or 2 cups regular Peroxcide to a Gal. of water poured thru the pot it will also get rid of the pesty fungus knats . Gin

    Default Too darn DRY around here!

    Please send some of your extra rain ASAP.

    Just wanted to say that when I use an outside pot around the growing pots, I put a few pebbles in the bottom to sit the inside pot on. I think it helps air get all around. Might not be sufficient as it is so damp where you are right now, though.

    Hi. I would repot the plant in fresh mix. Once you get the plant out of the pot, wash it (roots and all) really well with water. If you are careful, you can use very watered down bleach water to wash the roots, but it must be really watered down. Too strong could hurt rather than help. I would guess that it is an air circulation problem, but just to be on the safe side.... Repot with fresh mix after the wash.
    Cheers!

    that is a type of mould.its known as spider web mould.I dont know the cause but its normally the mix that it is growing in/on.In the past I have not bothered with it but it could be controlled by repotting the plant and watering the mix with a fungicide

    Thanks again guys - you are lifesavers as always. I'll give it a scrub, a more airy one pot home, and call it a day....
