Can someone help me out with my plant?

Question

So I have two of these plants, the lady who sold them to me said they were called Colombos. I just bought them last week. I water them twice a week, as instructed. They were both fine this morning. I have no idea what happened but suddenly one of them just collapsed. Here are some pictures.

This is the healthy one.

And this is the other one.

Answer 1

As some other answers read.... water is very likely the root. No pun intended. I would guess too much and that their roots are rotting. Hopfully though, it is just too dry and you can bring it back with a drink.
I really hate it when people give watering directions - how can anyone know what the growing conditions are going to be and thus prescribe correctly. You really need to get to know your plant and how quickly the soil dries out.
I have never heard of a Colombos but the plant looks like an Aglaonema to me.
If So:
They do not like too much water, but the soil should be kept uniformly moist. They are also very tollerant of and prefer deep shade place them away from direct light.

Answer 2

Have you moved one recently? If so maybe the healthy was the better spot. I would only water when the soil is starting to dry so it doesnt get to much water. That is odd how the other one just drooped like that. I have a lilly that if I move it to another window it starts to wilt. Definately isnt the kind of plant that needs/likes full sun.
Wish i could help more..good luck!

Answer 3

either too much water or not enough.. if both have been taken care of equally, then check the soil for parasites and remove the plant until they are eliminated. look under the leaves for evidence or close to the stem base. I'd also make a call to the florist where you got them... they may have a guarantee and will take the plant back.

Answer 4

It appears to be a variety of aglaonema.
The culture for this plant calls for light, semi-shady to shady.Temp. average house. Humidity, average house, but preferably 30% or more. Soil, equal parts loam, sand, and peat moss; keep moist at ALL times. Your watering schedule is a little suspect as you should water as needed, not necessarily twice a week. Stick your finger an inch or so into the potting medium to determine if it's moist or not. As previously stated, this plant should be moist at all times.

Answer 5

My first thought is overwatering or underwatering. Do the pots have drainage? (They should). When in doubt, pop the plant out of the pot and examine the roots. Soggy? Dry? That should be a clue. If roots look good, look for insect infestation - though this does not look like an insect attack. If all else fails, take the sorry one back where you got it. They should stand behind their stock.

Answer 6

I was wondering the same maybe the bad one likes to on the other side of the healthy one? Do you have them next to each other? Maybe they should be split up? Don't know much about plants. Why not ask the lady who sold them to you she might know.

Answer 7

Looks like diefenbachia to me.

They'll definitly collapse if they get dry. They need a thorough watering, the let get almost dry. If the stems are flabby, stake them up before you water them so they'll hold that upright shape.

Answer 8

I suggest cutting back on the water they look like they have been over watered. Check the soil and water when dry.

Answer 9

Needs water. Make sure they aren't in direct light either.

Answer 10

Looks to me its grown to death, the flower shops makes them grow to fast with to much fertilizer, then these things happen.
