Will sunflowers wither after their flowering period?
Today's introduction to whether sunflowers wither after their flowering period and the cleaning methods of withered branches and leaves in the field of green plants and flowers. Next, the editor will answer your questions in detail.
Many flower enthusiasts living in the city do not have the conditions for ground planting, and they want to plant common sunflowers or cream sunflowers on their balconies at home. However, the results are not satisfactory, always encountering various problems such as non-standard blooming or seeds not germinating, or the seedlings die for no known reason. Why is that? Because some issues have not been paid attention to during the sowing and maintenance of sunflowers. So here comes a nanny-level tutorial on how to avoid pitfalls perfectly when sowing and maintaining cream sunflowers.
I have an article that guides you through understanding the rare variety of cream sunflowers mentioned:
The sowing time for sunflowers is from April to August, with the best sowing time being from April to June. If you want to sow, be sure to catch this summer! The period from sowing to flowering of sunflowers can vary, approximately 45, 50, or 55 days. The germination temperature is above 15 degrees, and the suitable growth temperature is above 10 degrees. We need to be patient during this process.
So what should be paid attention to when planting and maintaining cream sunflowers on a balcony at home?
First, it is best to germinate the seeds before planting. There are several benefits to germinating first:
1. Prevent seeds from being eaten by insects after planting, increasing the germination rate of the seeds. Many flower enthusiasts plant seeds but they do not germinate, and in fact, the seeds are eaten by insects in the soil.
2. Speed up the germination process and almost synchronize the germination time of the seeds, making the flowering time consistent, which helps with cross-pollination. This is an essential step for those who want to try pollinating sunflowers and collecting seeds.
3. Germinating seedlings before transplanting allows the plants to grow faster.
Second, when growing sunflowers in pots, try to choose a larger high pot. Sunflower plants can grow up to about one meter tall, with a tall shape and the stem becoming thicker as it grows. A pot that is too small can easily be blown over by the wind (for a single plant, it is best to choose a pot of 1.5-2 gallons. See the picture below; I only used a 1-gallon pot, which is a bit too small and has been blown over by the wind directly).

In addition, as sunflowers grow larger and larger, their water demand also increases, avoiding drought due to lack of water or inconvenience from frequent watering.
Third, sunflowers with a single stem and flower do not require topping. Sunflowers will also wither on their own after flowering. If you are planting the 'Endless Sunlight' variety, then topping is necessary.
Fourth, cream sunflowers are sun-loving and fertilizer-loving plants that require full sunlight and adequate water and fertilizer to ensure the nutritional supply of the plant. Use 'Flower More No. 1' every week. If the temperature is too high, pay attention to watering to avoid drought. When you see sunflowers starting to form flower buds, apply phosphorus and potassium fertilizer to prevent insufficient nutrition and non-standard flowering.
The process of planting and maintaining sunflowers is relatively simple compared to other plants, but they can also have diseases and pests, which everyone does not need to worry about. Sunflowers have strong disease resistance, and common diseases and pests are only a small amount of aphids or thrips, or small caterpillars that eat leaves. If pests are found during planting, there is no need to spray pesticides; just remove them manually early on.
By doing the above points, your sunflowers will bloom normally with large and standard flowers.
From sowing to harvest is actually a very interesting and fun process, very therapeutic. If you want to plant sunflowers, don't miss the timing! Let's plant cream sunflowers this summer!
