When to Plant Sunflowers in Arizona

When to plant sunflowers in Arizona largely depends on the climate and weather conditions of the region. Sunflowers thrive in warm temperatures and plenty of sunlight, so it is important to choose the right time for planting to ensure a successful growth.

What is the ideal time to plant sunflowers in Arizona?

In Arizona, the best time to plant sunflowers is in the spring, after the last frost date has passed. This usually falls between late February and early April, depending on the specific region within Arizona. Planting during this time ensures that the soil is warm enough for sunflower seeds to germinate and that there is enough sunlight for optimal growth.

  • Plant sunflower seeds in early to mid-spring for best results.
  • Avoid planting too early when there is still a risk of frost.
  • Planting too late in the spring may lead to stunted growth due to the heat of the summer months.
