I'm not sure how much help I'll be, because I don't grow Aloe vera. The one you have looks like Aloe vera v. chinensis. Well, I take it back. I do have one little bitty one...my hubby brought home from work from a co-worker...in a baggie of WATER (almost like a fish)!! Its 2 outer leaves were mush. I pulled them off & set the remaining small part on the kitchen window sill. I forgot about it. It was there for weeks...no, months! It started growing! That's when I potted it up. So, reason I tell you the story...it doesn't need too much water. I notice the soil in your pot looks mostly like sand. Bad idea. Try to get it out of there. Sand will retain water. You need stuff to aerate, to let the water drain well. Do you have anything else available to you? A bunch of small rocks mixed in might help. As for the dents in the leaf...I don't know what causes it. But I would cut back on watering. Wait till you see some new growth on your plant. Water sparingly. Okay, update~I took a look at mine & 1 of the older leaves has a dent in it like yours. I believe the older leaves will desiccate over time & dry up, drop off. More than likely, this is what is happening on both our plants. Natural for the plant. =)

Certainly not here to dispute the name of the Lowes plant. I bought a couple of the same plants, chuckling to myself that ALL of the aloes were labeled Aloe vera. Mine are PIG, growing well and curiously have lost their spots. You can see some of the spots remain on the bottom, oldest leaves. So I'm pondering the label again. Of course it hasn't flowered yet (about 3 years old), which will add to the info. I guess I wonder if Aloe vera pups start with spots. I have no pups to compare. My plant does not look like the OP's first plants. This post was edited by Crenda on Thu, Aug 7, 14 at 10:23

Pic 4; wish I would know how to post multiple pictures at the same time. Aloe Vera ??

I'm in HOuston, so anything I say about wintering aloes may not sound relevant. However, I 'started' farming aloes while in Dallas and then 8 years in Tyler, due east of Dallas. This was when my aloe herd got to be over 300 plants, when I stopped counting. I found some plastic "trim" strips at Home Depot that are 8 feet long, about 1/4" x 1/2" and very flexible, for about a $ each. I bend them over my aloe bed and poke in the ground then tent over them with a plastic sheet. I anchor the edges of the sheet with old boards and bricks. I try to seal the edges as best I can, but the biggest concern is for the wind ripping it off. I usually only put the tent on them when the forecast is for less than 33degrees overnight lows, but if the forecast is for 34 to 36 for a week I might tent them just because the forecast can be unreliable. Since doing labor in cool/cold weather is painful, I often leave the tent on too long. When I take it off I usually find at least one of them is flowering.
