What to do if your peppers won't grow big? Use this method and your peppers will hang in clusters, plentiful and healthy

At home, on a balcony, or in a vegetable garden, growing some peppers is quite practical: plant them in spring and you can harvest them for months through summer and autumn. But among fellow gardeners, why do some peppers fail to grow big?
We've grown peppers many times on terraces and balconies. Sometimes the peppers we grow shoot up fast, a small seedling quickly becomes a large plant, and the peppers it sets weigh the branches down. Other times, the peppers we grow stay short and scrawny, with very few flowers and fruits.
Methods and tips for growing peppers at home
When peppers fail to grow big, it has a lot to do with the environment and the soil. For example, if you plant them in a very shady spot, such as on the north side or a north-facing windowsill, where sunlight is insufficient, they will only grow leaves and rarely flower, and the plant will stay rather small and not bushy enough.
But plant them on a sunny windowsill, a terrace, or even outdoors, and each plant grows especially vigorously, and it may even grow into a pepper tree.
Second, if pepper seedlings are planted too densely and the plants have no airflow or light between them, they easily get aphids or other pests, and they still won't grow big. So only by keeping good airflow, light and ventilation and giving them enough space can they grow healthily and vigorously.
Third, if the potting soil is especially compacted, hard as stone, and has little fertility, then the pepper seedlings will naturally stay small, and may even grow deformed. So either replace the soil and replant them, or add new, fertile, well-aerated soil. Only then can the peppers grow big and set plenty of fruit.
Pay attention to watering in normal times. Peppers do not need especially much water, but they must not dry out either. When they are flowering, do not water too much, so that waterlogging does not cause the flowers to drop.
When the peppers reach about ten-odd cm tall, you can pinch out the growing tip once, that is, pinch off the top shoots and leaves, to encourage more side branches to grow. After the side branches appear, pinch out their tips too, and this way the peppers can set at least twice as many fruits.
Then there is fertilising: apply plenty of fertiliser and top-dress often, whether it is leaf mould, cake fertiliser, chicken manure or sheep manure. The plant will naturally grow very large, and set especially many peppers, with especially big fruits.
