It's a pretty common phenomenon that chiliplantorna drops its flowers it is called to the abort when they shed their flowers on the way. This could mean that the plant is not doing well and the most common reason is for large temperature swings for hot or cold or the plant suffers from malnutrition and are stressed, for small pot, too little water, too much water.
Be sure to keep a consistent watering and give a small child nutrition on a regular basis instead of a big give nutrients such as 1 ggr i veckan. Make sure that it does not become too large temperature swings at night.
To chiliplantorna loses a bit of its flowers is a natural phenomenon if they for example do not become pollinerade. There will be new flowers which bloom chiliplantorna relatively long.
In order to promote the habit of blommning and later its fruit wrapping so I give my plants bone meal which is is a slow fertilizer with much phosphorus and not as much nitrogen.
Bone meal is rich in phosphorus (P) that promote bloom formation, fruit and root formation and nitrogen (N) fostering growth and lush green leaves.
Bone meal contains 7 % nitrogen and 9 % phosphorus and mikroämnen. It is, therefore, an NP 7-9 as well as micronutrient fertilizers.
When I give this industry so I drag down the other nutrients that contain much nitrogen (N)
I sprinkle it on Earth and stir and hoses down the whole thing you can even mix in soil at retraining to larger pot.
