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.
