Can I plant sunflowers directly in the ground or should I start them indoors?
Sunflowers, with their tall, majestic stalks and cheerful, sun-like blooms, are a beautiful and easy addition to any garden. But before you embark on your sunflower-growing journey, a crucial question arises: Should you plant them directly in the ground or start them indoors? The answer depends on several factors, including your climate and gardening zone.
If you live in an area with a long, warm growing season, you can plant sunflower seeds directly in the ground after the last frost date. Simply scatter the seeds thinly over the soil, cover them with a light layer of mulch, and water well. However, if you reside in a cooler climate or have a shorter growing season, starting sunflowers indoors is a better option. Sow the seeds in peat pots or seed trays filled with a seed-starting mix 4-6 weeks before the last frost. Provide plenty of sunlight or grow lights and keep the soil moist but not soggy. Once the seedlings have developed their first set of true leaves, harden them off gradually before transplanting them outdoors in well-draining soil with ample sunlight.
What type of sunflower seeds should I plant in Missouri?
Growing sunflowers in Missouri can be rewarding with the right variety of seeds. Mammoths are a popular choice, producing large heads with up to 500 seeds per head. For shorter growing seasons, try the Autumn Beauty or Sunrich Orange. These varieties mature quickly, reaching heights of 5 to 6 feet. If you prefer smaller blooms, consider the Teddy Bear or Elf varieties, which grow to 2 to 3 feet tall. Mammoth Grey Stripe is another good option, producing gray and black striped seeds that are popular for birdseed. Regardless of your choice, consider the height, maturity time, and seed size when selecting sunflower seeds for your Missouri garden.

What is the best way to support tall sunflowers in the garden?
Tall sunflowers, with their radiant faces and towering stems, add an impressive touch to any garden. However, supporting these gentle giants is crucial to prevent them from toppling over or breaking under their own weight. One effective method is to use stakes or poles. Simply insert a stake firmly into the ground next to the sunflower and loosely tie the stem to it using twine or plant ties. Ensure the stake is tall enough to provide adequate support as the sunflower grows. Alternatively, you could create a support system by tying three or four sturdy wooden stakes around the sunflower in a teepee-like structure. Interweave twine or wire between the stakes to create a framework that holds the sunflower upright and allows for air circulation.
