I bought an older home with a lot Aloe Vera plants. They are all bunched up and seem to be going dormant or dying. A neighbor mentioned I need to remove some of the plants because they are crowding each other. She mentioned they would be healthier if I do, also then I can weed better between the plants. She mentioned they need space and weeding. Is she right? If so, how should I decide which ones to remove?
Were the plants exposed to cold temperatures?
This would cause the decline of your plants.
If the plants have become to crowded, you can easily divide the plants and share with other gardeners.
Make sure the plants are growing in a well draining soil, to much water will cause root rot and the loss of plants.
