Q.I bought 4 shamrock plants. Two are doing fine and 2 are not. The 2 I mention are alive but not standing up they just fell over.
They are house plants. I had shamrock plants before; I had 2 of them that lived for 5 years. I never over watered them. Any idea of what the problem is? I don’t have a photo to upload.

Unfortunately, it will be hard to say what is going on without a photo, but my best guesses would be either a lack of light, or improper planting depth. It may not be deep enough in the soil. A photo will be necessary to get a better idea of what is going on.
In the meantime, this article will give you more information on the care of these: https://www.gardeningknowhow.com/houseplants/shamrock/growing-shamrock-plants.htm
