How to Set up It
Unlike other plants growing in containers, agave doesn't mind beingness root-spring. Even when the found outgrows its container, and the roots come out of the drainage holes at the bottom, it volition still non show signs of stress. Only other problems might show up, and caring for a potted agave has to be mindful of the following considerations.
- Make certain the soil or potting mix drains well but dries slowly. You tin use a succulent potting mix that retains moisture amend without beingness waterlogged.
- Line upward the lesser of the container with medium-size gravel that doesn't block the drainage holes and acts equally a buffer between the potting mix and the bottom of the pot.
- When repotting the plant, make certain the crown is higher up the soil line to forbid crown rot, a common agave problem that we expand on after.
- Identify the container on a window sill facing the west or due south and gets most half-dozen to 8 hours of sunlight a 24-hour interval during the growing season.

When the adult female person snout weevil bites the middle of the succulent to lay its eggs, it will die on the spot. You'll need to employ information technology once a calendar month during the spring and summer.
Another style to gainsay the insect is by using sprays. Just since the agave snout weevil has a thick shield on its back, nigh sprays fail to penetrate that outer shell, and the insect volition go about its business unbothered.
Agave Crown Rot
The crown of the agave is the role of the delicious that connects the roots to the leaves.

In fact, moisture is the number one culprit behind agave crown rot.
That moisture could come from to a higher place if you tend to water the succulent from above. A few drops of water that fall into the heart of the rosette can be plenty to cause crown rot. Other times, the subversive effects of the agave snout weevil might starting time the crown rot concatenation reaction that ends with the demise of the whole establish.
