How to keep petunias in winter at home

Position

First of all, petunias should be placed on the windowsill as much as possible in winter, or in a sunny indoor location near the windowsill.

Secondly, you should pay attention to ventilation, which includes ventilation when you first enter the room and ventilation throughout the winter. You should open windows for ventilation in sunny weather with good lighting conditions. Long-term persistence can help flowers reduce the threat of diseases and pests and make them grow stronger. Because sufficient light is the key to petunia's growth, ensuring sufficient light is the key to petunia's successful wintering.

Watering and fertilizing

As the temperature continues to drop after winter, the metabolic rate of petunias gradually slows down, and the required water and fertilizer are very little. At this time, you can water and fertilize the petunias according to the actual situation.

Watering

First of all, we should follow the principle of "don't water unless the soil is dry, and water thoroughly when we do." The purpose of implementing this principle is to prevent petunias from rotting roots, falling leaves or growing too tall due to excessive water absorption, which will cause the differentiation of flower buds and weakening of cold resistance.

Secondly, the water used for watering flowers in winter also needs to be exposed to the sun before use. This is to make the water temperature close to room temperature.

The best time for final watering is around noon. If you choose to water in the evening, the cold temperature may cause frost damage to the roots of the flowers.

Fertilization

Fertilization should be based on the specific growth conditions of petunia and appropriate nitrogen fertilizer should be applied.

Other tips for wintering

Because the air is relatively dry in winter, you should often use water close to room temperature to spray the leaves of petunias indoors to keep the leaves clean and promote normal photosynthesis. However, be careful not to increase the moisture in the potting soil when spraying water on the leaves to avoid root rot.

Winter is also the season when pests such as aphids, scale insects, and whiteflies are prone to occur, and prevention and control work must be done at all times. Try not to spray with pyrethroids after aphids appear, so as to avoid causing pesticide damage, which will be detrimental to the growth of petunias.
