Sunflower is a gorgeous flower with thousands of tiny flowers gathered into a round disc in the middle. [1] X Research Sources Many popular sunflower varieties grow very quickly, have good drought tolerance and disease resistance. Shield your plants from the wind and protect them from pests, and you’ll have a beautiful garden all summer long.
Steps
Planting sunflowers
- The classic yellow-flowered sunflower with only one stem is usually very fast growing and easy to grow. Sunrich and Pro Cut are sunflower varieties suitable for beginners. [2] X Research Source
- In branched sunflower varieties, each seed can produce many flowers, but the plant will grow more slowly. If you’re picking flowers, choose a pollen-free or low-pollen variety like Cherry Rose to avoid soiling. [3] X Research Sources
- Large-flowered sunflower varieties such as Mammoth Gray Stripe and Humongous typically produce better-tasting seeds, and can support climbing plants. [4] X Source of Research[5] X Source of Research (Some smaller varieties will produce seeds of only a quality suitable for bird food).
- Short day plants: These plants need a long night time to stimulate bloom. You should plant this plant in late summer (or start growing indoors in mid-spring).
- Long-day plants: Long-day plants usually bloom in mid-summer.
- Medium-day plants: Plants of this type can be planted at any time of the growing season.
- Plan ahead based on when the plants bloom. Most single-stemmed sunflower varieties will bloom 60 days after seeding, while branching varieties will bloom after 90 days. [7] X Research Sources
- If the soil is barren, add about 7-10cm of compost to the topsoil. [10] X Research Source
- Sow more seeds if there is plenty of room. You can prune after the seedlings have sprouted, plus some seeds may be lost to pests.
- Sow the seeds 15 cm apart for small flowers suitable for bouquets, or 23 cm or more apart for larger flowers. [13] X Research Source
- If the flower variety you are growing has a maximum height of more than 1.5 m, you need to plant the plants at least 30 cm apart. Giant sunflower varieties can grow to more than 50cm wide. [14] X Research Source
- Most branched sunflower varieties need a width of up to 45 cm. [15] X Research Source
Sunflower care
- If the leaves appear normal but have an unusually prominent yellow color, the plant may have a bacterial infection, not a fungal infection. Keeping the soil dry in this case also helps, and usually the plant will be fine.
- If the leaves turn yellow but the veins remain green, the problem is probably a mineral deficiency. Finding the exact problem is a bit tricky, but diluted fertilizer can work.
- Note that when the sunflower begins to take root, it is normal to lose the first pair of leaves. Don’t worry if the lower leaves wilt and fall, but the rest of the leaves are still healthy.
- Try not to get the flower wet to avoid damage to the flower. [21] X Research Source
Harvest sunflower seeds and flowers
- Cut flowers in the early morning or early evening.
- Use a knife or scissors to cut the tree clean.
- Remove any leaves that are below the water level in the jar.
- Put the flowers in the water right away.
- Most sunflowers will have more seeds if you attract bees to your garden to pollinate the flowers.
- Store the seeds in a cloth bag to allow air to circulate. This helps prevent mildew.
Advice
- Prune the plants by removing the weakest seedlings if you want the flowers to bloom to their full potential.
- The seeds that fall to the ground can harm the following year if you are not careful. To control the number of plants, you should prune dead flowers before the seeds fall.
- Sunflowers will shade themselves to overwhelm the weeds. You only need to weed when the seedlings are growing.
- Sunflowers usually do not need to be pruned. Prune away the bottom leaves if they are wilted and cut off dead flowers on branched plants. [25] X Research Sources
