Hello everyone,first of all I am glad that I found this site,health and prosperity to you guys and your flowers(lol).
On to bussiness then,I have several flowers which are starting to have some problems,and I do not know their name,honestly I don't know the name of any flower that I have in my house,but whatever.
I would like if possible to identify these plants and tell me why are they having these problems,and how to solve them:
Flower number one : http://postimage.org/image/3kyjgujm3/
It's problems : http://postimage.org/image/djji3bt1n/
Flower number four : http://postimage.org/image/d0eeu21mz/
It's problems : almost all of her leaves began to go yellow,I removed almost all of them but I think there are a few left which I'm not sure to remove or not.
#1 Dieffenbachia, looks like something/someone bumped into the leaf, causing it to bend too far. What a big, beautiful plant!
#2 Chlorophytum, spider plant. Those are baby plants with aerial roots hanging off of it in the 2nd picture of it. Removing the yellow leaves would make it look a lot better.
#3 Anthurium, an impressively large one!
#4 I can't tell if that's a Dracaena or Aglaonema modestum.
#5 Anthurium with another plant I don't know. Amaryllis/Hippeastrum? That would be a bulb. That leaf looks like it got torn by mechanical means like the first plant, the Dief. The white residue may be sap that leaked out of the plant when that happened.
I think your plants all have the same issues, roots in need of new soil. The "sticky" at the top of the house plant forum, which is what most people chatting on Dave's would consider these plants, is well worth your time in reading, IMHO.
On number one it is indeed true that I have a friend of mine that ocasionally bumps into it :)),nr.2 also true that it may have been possible for low humidity,the ground was alwasy rock hard,I would have put water today,tomorrow the ground was rock hard,now it is ok,overall the humidity in the air might be something to do with it,my mother always turns the heat on,and I love cold,so it's a constant switch between cold/hot,and when I wake up in the morning I always see a bit of water on plant nr.1
That's guttation, perfectly normal. That's a very good suggestion for #4, Moonhowl.
Daniel, you may also want to investigate an alternative water source than tap water, which can contain fluoride, chlorine, chloramine, and lime. Some plants don't mind, some, like Dracaena, are very sensitive.
Your houseplants look good to me. If you aren't feeding them, you might want to get some houseplant food. I use the kind you mix with water, but there is also Osmocote that you put right in the soil. You can also check to see if they need to be repotted, if they are rootbound, or if they just could use new soil. This always revives them. Don't sweat the small stuff, plants are living things and occasionally get damaged. Now if you start seeing bugs . . . you need to do something about it.
I agree about the tap water, I am on a well so I don't have to worry about it, but some plants really don't like tap water.
Oh, the temperature change shouldn't be that much of a problem. Most houseplants are tropical or semi-tropical plants and like heat, just don't let them freeze.
I just thought of something else. I have my anthurium in a large glass bowl to keep the humidlity in. You can mist it occasionally or even if you put it in a flat dish of water it will fair better. They are rain forest plants and I wonder if the brown spots aren't just because the air is so dry.
