How to cultivate pennywort in winter

As the name suggests, pennywort is a plant with a special aroma, which is characterized by the fact that it can release the aroma with a light touch. However, this plant has a weak tolerance to cold, and many flower lovers lack proper care knowledge in winter, which often causes the catnip to fail to survive the cold winter. Let’s learn how to grow catnip in winter.

1. Anti-frost measures

The plant is extremely sensitive to frost, which can kill its stems. Therefore, before winter comes, measures should be taken to prevent frost damage. Home-grown petals should be placed on a semi-enclosed sunny balcony or in a sheltered place at night, and the indoor temperature should be kept above 5°C. You can use plastic bags to wrap the plants at night to keep them warm. When there is sufficient sunlight during the day, you can remove the plastic bags and let the plants grow in the sun.

2. Moisture management

In addition to low temperatures in winter, stagnant water is also a common cause of death of catkins. The frequency of watering should be controlled to avoid water accumulation which may lead to root rot. As the temperature drops, watering should be reduced further. Because there are fine hairs on the surface of the leaves of the catnip , you should avoid watering or spraying water directly on the leaves to prevent the leaves from rotting.

3. Ventilation

Although indoor cultivation can help the catnip protect against cold, long-term closed environment is not conducive to plant growth. Windows should be opened regularly for ventilation to improve air quality and avoid poor growth or yellowing of leaves. During the day, you can open the window for half an hour or leave a small gap to promote air circulation.

4. Lighting enhancement

In winter, you should ensure that the catnip gets sufficient light, because under low temperature conditions, the plant not only needs a suitable indoor temperature, but also good light conditions. The sunlight is weaker in winter and will not harm the plants.

5. Fertilizer management

In winter, the nutrient demand of catnip is lower and no additional fertilizer is needed. Fertilize once before winter comes, preferably with phosphorus and potassium fertilizers, to ensure that the plants have enough nutrients to survive the winter.

The above is an introduction to the key points and precautions for caring for Pogostemon cablin in winter. Pogostemon cablin is not cold-resistant, so everyone must pay attention to taking warming measures.
