How to grow cornflowers on the balcony and what to pay attention to

Cornflower is a long-day plant and needs a long period of sunlight during its growth process. Maintaining sufficient light can ensure good growth, better and better growth, and the flowers can bloom smoothly. You can keep it at home on a balcony so that it can receive sunlight. Especially in winter, the sunlight is weaker and shorter, so it can be exposed to full sunlight. The summer sun is too strong, so you still need to be careful not to place it where it can be exposed to direct sunlight.

2. Moisture Application

Cornflowers cannot grow without water. During the period of vigorous growth, they need to be watered once a day. In the summer, evaporation is vigorous and the environment is relatively dry, so more watering is needed to keep it moist. However, do not apply too much water to prevent excessive water accumulation, otherwise it will cause root rot.

3. Fertilizer application

It prefers fertilizer, and needs to maintain sufficient fertilizer during the period of vigorous growth. Liquid fertilizer can be applied once every 20 days, but the concentration should not be too high. Before flowering, you need to apply more phosphorus and potassium fertilizers to ensure that the flowers bloom.

4. Temperature requirements

During the maintenance period, the temperature also needs to be paid attention to. It is more appropriate to keep it at around 20 degrees.
