Tips and Advice for Growing Sunflowers
  • One of the basic tips is that these plants need to be planted in an area that gets full sunlight.
  • It's a good idea to soak the sunflower seeds in some warm water, the night before planting them.
  • They should be planted after the last frost in the area you live in.
  • The seeds should be planted 6-inch distance apart, and at the depth of 1 inch. After planting, make sure to water the soil well.
  • The sunflower seedlings generally germinate in a couple of weeks, and reach maturity in 80 to 90 days.
  • Since they flower earlier, 4-inch peat pots that are placed indoors, can be used to start the planting of the taller varieties.
  • Generally, seedlings need to be thinned at a distance of 12-18 inches. However, if they are grown in containers, they can be planted closer together.
  • The roots of some varieties grow down deep, and also spread wide. Hence, make sure to use a container that is large enough.
  • The large varieties of sunflower plants may require staking.
  • The soil in the containers needs to be kept moist. Plus, it needs to be fertilized every two weeks with ½ strength liquid organic fertilizer.
  • Sunflower plants require plenty of water. However, care must be taken not to over-water them, because that can result in deformed seed heads. The soil you use should be well-drained, and yet kept evenly moist.
