Agave plants do not typically need pruning, but there are a few instances when it may be necessary: 1. Remove the spent flower stalks: After an agave plant blooms, the flower stalks will eventually dry up. To maintain the plant's appearance, you can cut off the dried flower stalks. 2. Remove dead or damaged leaves: If a leaf is brown and crispy or damaged, it's best to prune it off at the base. This will help keep the plant healthy and attractive. 3. Control the plant's size: If an agave plant is getting too large for its space, you can remove the oldest leaves at the base of the plant. This will help to reduce the overall size of the plant. However, be careful not to cut off too many leaves at once as this can cause stress to the plant. When pruning an agave plant, it's essential to wear gloves and eye protection as the leaves can be sharp. Use clean, sharp pruning shears to cut the leaves at the base.
