The agave ovatifolia plant has minimum water needs. It easily thrives on low water requirements.
However, they can grow much larger with regular irrigation.
- In the first month, water young plants every 4-5 days.
- Next, change your watering schedule to once per week.

- Provide additional water only when the top inch or two of the soil is dry.
- The plant has low fertilization needs.
- For the long life of the plant, it is better to keep the fertilizer away from it.
- However, if you wish to encourage flowering, feeding can do wonders.
- In this regard, it is crucial to remember the agave plant dies soon after flowering.
