Indoors: Mexican Sunflowers are warm-climate plants that germinate best when soil and air temperatures are warm. In short-season climates they may be sown indoors, which is easy to do, 4 - 6 weeks before safe planting out time (first week of June in southern Manitoba).

We recommend applying a kelp supplement such as Sea Magic starting at the time of sowing.

Mexican Sunflowers may also be direct seeded once all chance of frost has passed.

Growing in Containers: Well suited to larger pots, 30 cm (12") and up.

Fertilizing (Containers): Feed with a bloom-oriented organic fertilizer such as Evolve Fish Bloom 2-3-1, applying weekly through the growing season for maximum plant vigour. 

Watering (Containers): Mexican Sunflowers are more drought-resistant than many annual flowers, but benefit from deep watering every 4  - 6 days when grown in containers (of course, if plants look drought-stressed, water sooner).  

Growing in Mixed Planters: Well suited to larger mixed planters. 

Fertilizing (Garden): Amend garden soil with compost annually. No further fertilizer required.

Watering (Garden): Water regularly to establish. Water mature plants weekly during hot weather. 

Beneficials Attracted to this Plant: Many butterflies

Suitability for Indoors: Not suited for indoors.
