Tea is indeed a popular food supplement for some types of indoor plants.
Dry tea leaves can be added to the pot if you are sure that the components contained in it will not cause harm.
Black, green and herbal tea are suitable as a supplement - the main thing is that it does not contain additives or inorganic fragrances.
It is also important to remember that flowers may need acidified soil - check with litmus paper.
Flavored tea should never be added as this can cause root rot and disrupt the nutrient balance.
You can’t water it with tea leaves containing sugar, as this will cause fungus to form.
You can't use moldy tea that has been sitting on the table for a long time. For plants that like acidic soil, watering with tea will only harm them.
