What are the reasons why flowers don't thrive? Read on and you'll understand

Summer arrives right on schedule again
Many friends are delighted to receive flowers
But there are always those who can't keep them well
And don't know how to care for them
After two or three days they still haven't bloomed
Why has the center of the Gerbera daisy gone moldy
The roses drooped after just two days
Why have the lily petals turned black and rotted
Why won't the water lily bloom
What are the reasons for these?
Let's explain below how to care for them
1 "Why does the center of the Gerbera daisy go moldy"
In this season, especially in the humid south, the whole environment is very damp, so apart from a few special flower varieties, do not spray water on the flower heads. With flowers like the Gerbera daisy, once the flower head gets wet, the center is extremely prone to mold, and once one goes moldy, it easily spreads to the other flowers, so if you find a flower head going moldy, be sure to take it out promptly.
2 "Why do roses droop after just two days"
The weather is getting hotter and hotter, water evaporates very quickly, and fresh flowers dehydrate easily. If the water-absorbing opening at the base of the stem is not very clean, it becomes even harder for water to travel up to the flower head, so when keeping flowers in summer you can cut the base at a steeper angle to increase the area of the water-absorbing opening. Don't put the flowers in the sun just for the sake of looks; direct sunlight speeds up dehydration.
So here comes the question!!
Can roses still be saved after they droop?
Yes, here's the emergency method: when fresh flowers droop, cut off a small section from the end of the stem, then place it in a container filled with cold water, leaving only the flower head above the water. After 1-2 hours, the stem will revive
3 "Why do lily petals turn black"
If you want lilies to last a long time, pay attention to trimming the stems; if the stems stay in water for a long time, they will inevitably rot. Trimming the stems every day is to keep the water-absorbing point fresh, so that the lilies can absorb fresh water and nutrients every day. The trimmed length doesn't need to be too long, about one centimeter is enough. There is one more thing to note: once your lily opens, as soon as you can see the anthers inside, be sure to remove the anthers promptly, because the pollen in the anthers will stain the petals with color that cannot be removed, especially for white lilies, which greatly affects the flower's appearance and can also cause rotting.
4 "Why won't the water lily bloom"
After unwrapping fresh flowers, you need to peel open the thick green petal skin on the outside of the flower head, because water lily petals are very thin, and if you don't peel open the petal skin, they have no way of pushing it open on their own, so naturally they cannot bloom.
