How long does a sunflower bloom
Talking about the blooming time of sunflowers and the knowledge of green plants and flowers related to the meaning and symbolism of sunflowers, here comes the comprehensive introduction.
Almost everyone who likes to grow flowers has heard of the sunflower plant, and many people think that sunflowers are very easy to grow, even beginners can take care of them well. However, many people encounter problems when trying to make them bloom, especially as we have entered the season of their mass blooming. With high temperatures in summer and fast growth, the blooming ability is strong, but many people's sunflowers do not bloom. Today, I'll tell you that if you want them to bloom, three "conditions" must be met, and missing any one of them won't work.
1. Need sunlight
Sunflowers can grow normally in indoor environments with weak lighting, but they may develop spindly branches if they lack sunlight. Without light, they won't bloom at all. We need to remember their blooming time: sunflowers generally start blooming from noon and continue until 4 or 5 PM. When the sun sets, they will close completely, and they will bloom again during the same time the next day. Therefore, we need to ensure they get plenty of sunlight. If you want to see flowers, there must be sunlight in the afternoon. Without afternoon sunlight, even if flower buds form, they won't open.
2. Don't use the wrong fertilizer
Does sunflower need fertilizer? Yes, it needs fertilizer for both growth and blooming. However, don't use the wrong type of fertilizer. If the seedlings are small, you can use multi-element or high-nitrogen fertilizers. But if the plant has grown long and large, and you want it to bloom, don't use high-nitrogen fertilizers, as they will only make it grow more branches and leaves without blooming. Using the wrong fertilizer will lead to this situation.
So when the branches are lush and the main stem is thick, switch to high-phosphorus fertilizers, such as No. 2 of Huaduo, applying it once or twice a month. This way, your sunflower, whether in a pot or in the ground, will be able to grow flower buds at the top of the branches. It's not a problem to have two or three flower buds on a single branch, and while the branches are growing, they will continuously produce more flower buds.

3. Do not prune
Sunflowers have a characteristic: they bloom from the top of the branches, not from the point where the branches, leaves, and stems connect. So if you frequently prune and pinch the top during the care of sunflowers, they won't bloom because they won't have a top. If you want to see flowers, don't prune. You can pinch and prune the small seedlings in the early stage, and the remaining branches will quickly grow lateral buds. When they grow into a full pot, you can let them bloom. As long as you stop pruning, and after the branches have grown long, you can proceed with the operation. By providing plenty of sunlight and using the right fertilizer, the flower buds will naturally grow.
Sunflowers are also known as "immortal flowers," very easy to grow. If you can't make sunflowers bloom, check which of these three conditions you are missing. As long as you improve them reasonably, they can bloom from spring to winter in your home, provided the indoor temperature does not drop in winter.
