Must Sunflowers Be Planted Outside?

Learn how to plant, grow, and care for sunflowers, the bright and cheerful flowers that attract pollinators and produce edible seeds. Discover different varieties, planting times, soil and water needs, and tips for successful gardening. Sunflowers need sun, so grow them in rich, fertile soil in a sheltered, sunny spot. They grow well in pots but are best grown in the ground for height.

Plant sunflowers outdoors or indoors, choosing the best varieties, and caring for them until they bloom. Clear the ground of weeds and dig in compost or well-rotted farmyard manure before planting. Space plants 45cm (18in) apart and water well after planting.

Sunflowers grow best in locations with direct sunlight (6 to 8 hours per day) and require long, warm summers to flower well. Transplanting sunflower seedlings is difficult, but in Zone 8A, you can plant them in the ground when weather warms up. Sow sunflower seeds indoors in March, but wait until they are good sturdy plants, about 30cm tall, before planting outside.

Sow sunflower seeds indoors in pots in April and plant out in May once all risk of frost is past. Follow this process for super summer sunflowers. To give them the best start, sow indoors as germinating seeds and young plants need protection from frost. Alternatively, direct sow outdoors later.

Sunflowers are low-maintenance and drought-tolerant flowers that grow in most soil conditions, providing flowers with plenty of daily sunlight.

Can sunflowers get too much light?

Slender sunflowers are not invincible plants, but they can be damaged by too much sun. Brown patches on leaves, crispy leaves, or faded, bleached looks are signs of too much sun.

Keep an eye on moisture levels, as parched sunflowers are more susceptible to sunburn.

Tailoring sunlight for thriving sunflowers is essential. As the earth tilts, sunlight plays hide and seek with your plant. Position your sunflower for longer days in spring and summer, and find a sweet spot where weaker rays can still kiss its petals in autumn. In winter, consider it as the sunflower’s nap time, with less light allowing for a well-deserved rest. Remember to create a sun-safe haven for your green friend.

Why is my indoor sunflower dying?

Insufficient water can cause sunflowers to wilt and droop their heads, while overwatering can lead to root suffocation or nutrient imbalance. Weak plants can also cause the stem to not support the flower, causing it to droop or slump over. Additionally, not enough sunlight can be detrimental to the blooms, as sunflowers naturally orient themselves toward the sun, a phenomenon known as heliotropism. Insufficient sunlight can cause the heads to droop as they try to maximize sun exposure.
