Hydrangeas won't bloom, yet everyone else's are bursting with flowers pot after pot. Where's the problem?

How do you care for hydrangeas so every pot bursts with blooms? Let's take a look! The hydrangea is a very special flowering plant, with flower colors generally white, purple, or blue. But the flower heads are very large, and it also blooms and bursts into pots very easily. It's very suitable for planting in the ground, and some people like to grow it in pots on the balcony. In short, when it comes to growing flowers, this hydrangea is something every woman must grow.
One thing to note: although the hydrangea is also a flowering green plant, it is a green plant that prefers shade. Too much sun actually makes it grow poorly, and it also makes it hard for it to bloom. So if your hydrangea blooms little, could this be the reason?
So how do you care for hydrangeas so they bloom more and have a longer flowering period? Let's learn about growing flowers together. (These are words from experience; if anything is wrong, please leave a comment.)
Nutrient issues
When hydrangeas bloom a lot, their nutrient needs are naturally relatively high. But the hydrangea is also a somewhat picky green plant. Generally, before it blooms, you can use a higher-nitrogen fertilizer or an organic nutrient solution for promoting seedlings. When it blooms, you can spray a high-potassium fertilizer or a professional bloom-promoting product. Generally, during the full flowering period, you basically need to control water and fertilizer, otherwise the flowers tend to drop.
Soil selection
The soil should mainly be one that is breathable and retains water, and the higher the organic matter the better; different PH levels give hydrangeas different flower colors. Generally speaking, under weakly acidic conditions, the flowers produced are pink. We can use ferrous sulfate or slightly acidic soil. This can make the hydrangea's flower color look better.
Water more for beautiful flower color
As mentioned earlier, one way to improve hydrangea flower color is to adjust the PH. Among these, using calcium fertilizer to improve it is not obvious. A simple method is to dilute vinegar and spray it, but that is not safe either. Of course, you can also use ferrous sulfate, which is also not bad. However, at present the safest is to use an acidic organic nutrient solution for foliar spraying (before it blooms; after it blooms, do not spray), as this can improve the flower color situation.
Alright, if you want to grow hydrangeas that bloom a lot and have good flower color, you need to learn the following points.
1. Control sunlight
2. Fertilize appropriately
3. Adjust PH
