How to care for petunias in winter? A full guide to winter care tips
In winter, indoor air is relatively dry, so we need to spray petunias with water to remove dust and keep them clean. Just spray the water on the petals and leaves; do not let the water in the pot increase. The temperature, of course, must also be kept at normal room temperature. Although there are relatively few pests in winter, petunias grown indoors can still be damaged by aphids, whiteflies, scale insects and other pests, so attention must be paid to prevention and control, and pests must be removed promptly when they appear.
Do you know how to help your petunias make it through winter smoothly? I believe that by using the methods above, your petunias will surely get through it healthily. Plants, like people, need to be cared for attentively. That way, your plants will surely bring you a good mood too.
Winter care and management tips for potted petunias
Key spring care points
Propagation: Sow in spring and autumn when the temperature is 20-22°C. Sown in autumn, they bloom in late March of the following year; sown in April, they show flowers in mid-August.
A cutting method can also be used: early spring and after the weather cools in autumn are the most suitable times. Cut vigorous young shoots as cuttings, 8-10 cm long, leaving 2-3 leaves on the upper part of the cutting. Use sand and plant ash mixed evenly in equal parts as the medium, and a planting depth of 2-3 cm is best.
Temperature/light: Ensure sufficient light during the growing period.
Watering: Keep the potting soil moist but on the dry side.
Fertilizing: For potted plants, base fertilizer is the main thing. Do not apply too much nitrogen fertilizer during the growing period, otherwise the plants will grow leggy and fall over.
Key summer care points
Watering: Reduce watering before flowering, and water adequately during the flowering period.
Temperature/light: Ensure sufficient light. Above 25°C, provide shade and cool the temperature down.
Fertilizing: After flowering, apply once every 15 days a 5-fold dilution of decomposed liquid fertilizer mixed with 1000-fold potassium dihydrogen phosphate.
