If the bloom is a couple of weeks old, the black color is a signal that the bloom is spent and in decline especially if the leaves are green and healthy. This is a normal process that occurs with every bloom. Simply remove the spent bloom by following the stem to the base of the plant and cut it off.

WHY DO rose petals turn black?
1) Sunlight; Pigments in red roses are particularly sensitive to sun-burning. There is no way for the rose bush, on its own, to move enough moisture to those extreme petal edges to stop the freeze burn effects, thus resulting in edges of rose petals turning black.
Why are the tips of my plant turning black?
Plants naturally use and lose water through their tissues each day. Leaf tips turn brown when that lost water can’t be replaced for some reason. This includes providing the plant with too much water, too little water or too much fertilizer. Root damage or distress also prevents roots from doing their job.

What does overwatering look like?
Stunted slow growth accompanied by yellowing leaves is also a symptom. Leaves falling off often accompanies this symptom. If your plants have yellowing leaves and old leaves, as well as new leaves that are falling at the same accelerated rate, you are overwatering.
How do you tell if Underwatering vs overwatering?
Feeling the leaves and the soil is the best way to differentiate between overwatering and underwatering. If the leaves feel dry & crispy, you are underwatering the plant. If it is soft and droopy, you are overwatering it. Also, dry and crusty soil indicated underwatering, whereas soggy soil indicated overwatering.

Rescue Techniques for Wilting Plants
- Move your plant to a shady area even if it is a full-sun plant.
- Check your pot for proper drainage and, if possible, create additional air space around the roots.

Can flowers be black?
In nature, flowers come in pretty much any colour you like – as long as it’s not black. The pigments that flowers employ to colour their petals don’t produce black. One of the earliest developed was the black tulip. There are now varieties of black rose, viola and hyacinth.
Why are black flowers rare?
“Black petals are out of the question because the pigments that colour flowers don’t occur in black,” explains Alastair Culham, a plant scientist at Reading University. Darker plants have rougher petal surfaces, which make them less reflective. Black petals might be fashionable at Chelsea, but in nature they are rare.
Can flowers naturally be black?
There are no true or completely black flowers that grow naturally in nature. Black pigments used to color petals and foliage don’t occur in plants or flowers. For example, scientists found that the popular black flower Alcea rosea ‘Nigra’ contains 9 different anthocyanins to create the black flower color.
Why do my flowers look burned?
Heat causes a plant to shut down, and it won’t take in moisture. If the air is too dry, moisture may evaporate from the plant’s leaves and cause it to scorch. Too Much Light. If you put a shade-loving plant in a sunny location, this can also cause leaf scorch.
What do you do with burnt flowers?
You will want to trim the dead or scorched foliage after properly watering. Your plant is expending energy on attempting to keep the burnt parts alive. Clip these areas off so that the energy it produces will go to the areas of the plant that are still healthy.
How do you treat sunflower scorched flowers?
“If you find your plant has been burnt, it is best to cut off the damaged leaves or trim them if you can,” says Steinkopf. “They will not heal or turn green again.” Then move your plant into a less bright area—choosing filtered light over direct sun—whisper your deepest apologies to it, and resume proper care.
