I've had this plant for about 5 years, it was doing really great, I've repotted it three times and it just kept growing . Ive kept It In the same windowsill too. It's been a little sad looking a few times, but not like this. A portion of the main stalk is brown and dry, all of the rest of the stalks are extremely shrunken and deep green. I water it about once or twice a week. What am I doing wrong?!

Can you post a photo? Also can you describe what type of soil you have it planted in and orientation of light, is it in a north, south, west or east position.

But basing on what you said, I am thinking it got overwatered. Depending on your location, and the season..like we just came from Winter to Spring, succulents do not need frequent watering during the cooler months. I would also check the roots to see what is going on under the soil.

I agree that a photo might help in determining the problem with your Aloe but the issues with your plant could very well be from not enough sunlight and too much water ... Aloe's are very succulent and watering twice a week seems extreme.

My aloe are lucky to get watered once every two weeks, and even less in the winter months.

I have a large potted Aloe plant that stays outside year round and it only gets water when it rains.
