Agave is a plant that is native to Mexico and in zones between eight and ten. Agave plants are to not be watered overhead. Agave snout weevils inject bacteria into the agave plant and it creates lesions on the plant where the critter lays its eggs. Plant rot may be reduced by using neem oil, thiophanate, or methyle. Parts of the plant that are chewed should be removed and the cutting device cleaned with bleach to prevent further contamination.
- While typically a simple plant to develop in shake gardens and hot, dry regions, agave can be vulnerable to bacterial and contagious decays if presented to excessively dampness and moistness.
- Cool, wet spring climate that quickly changes to hot, moist summer can bring about a surge in parasitic development and nuisance populaces.
- Mid to late summer crown spoil of agave plants can be basic in cooler atmospheres and pruned plants.
“The best way to prevent root and crown rot of agave plants is to situate them in a location with excellent drainage, infrequent irrigation and full sun.”
