Four seasons maintenance method of petunia

Autumn maintenance

Temperature and environment

In autumn, petunia is best sown when the temperature is 20℃. The seedlings can be transplanted when they have 5-6 leaflets. Attention should be paid to temperature control. Seedlings planted in an environment of 15-20℃ can grow more vigorously!

The temperature drops sharply in late autumn and early winter, so it is necessary to take anti-cold measures in advance to ensure that petunias grow in an environment above 0℃. Appropriate low temperatures can also help petunias grow into sturdy and short plants.

soil

When caring for petunias in autumn, you should pay attention to the fact that the soil should be loose, well-drained sandy soil. After the seedlings are successfully planted, keep the soil moist, provide sufficient light and avoid waterlogging.

Watering and fertilizing

Autumn is the favorite season for petunias and no fertilizer is needed. Water in the morning and evening to ensure the soil is moist, and get plenty of sun!

Placement

In autumn, petunias are suitable to be placed on balconies facing south, east or west, and should be avoided from exposure to the sun while ensuring sunlight.

Winter maintenance

Temperature and environment

The temperature for petunias to safely overwinter is around 0℃. Basically, they can be left to fend for themselves outdoors in temperatures below 0 degrees. Place the petunias in a warm indoor environment in winter. The petunias blooming with bright smiles may make your balcony more lively!

soil

When caring for petunias in winter, you should pay attention to keeping the soil in the pot moist and water them 1-2 times a week. Pay attention to the ice-shaking properties of the soil in winter.

Watering and fertilizing

As the temperature continues to drop after winter, the metabolism of petunias will become slow and their demand for water and fertilizer will be very low, so operations should be carried out according to actual needs. The principle of watering is not to water unless the soil is dry, and to water thoroughly when you do. Avoid root rot, leaf fall or excessive growth of young branches caused by stagnant water.

The water used for watering flowers in winter must be exposed to the sun to get close to room temperature before use. It is best to water at noon when the temperature is higher, and avoid watering at night when it is cold, which may cause frostbite to the roots.

The fertilization of petunia in winter depends on the actual situation, and nitrogen fertilizer can be used appropriately.

Placement

An enclosed balcony facing south, east or west is the best choice. Caring for petunias in winter can effectively prevent them from being damaged by natural disasters such as wind, frost, rain and snow.

Spring maintenance

Watering and fertilizing

Spring is a good season for petunias to sprout and bloom. While ensuring sufficient water, they should be exposed to more sunlight. Fertilization can be done once a week with a thin layer of nitrogen fertilizer, and moderate fertilization should also be applied during the bud stage.

It is important to note that excessive use of nitrogen fertilizer can easily cause excessive growth, excessive vine length, etc., causing the plant to be too tall and to fall over.

Placement

In spring, it is suitable to place petunias on balconies facing south, east or west, so that they can be exposed to the sun while being bathed in sunlight.

Summer maintenance

Temperature and environment

Petunia is not very resistant to high temperatures, so in the summer when the temperature is high, special attention should be paid to cooling down.

The specific method is: provide appropriate shade, sprinkle water around the bottom and increase ventilation, and reuse the evaporation of water for cooling.

soil

Summer is relatively humid, so just keep the soil in the pot moist but slightly dry. During the hot summer season, if the soil in the flowerpot is too wet, it can easily cause the petunia roots to rot and die.

Watering and fertilizing

In summer, the moisture in the potting soil evaporates very quickly, so the frequency of watering should be appropriately increased compared to other seasons. It is recommended to change to 2-4 times a week, and don't water too much each time.

In summer, petunias do not need to be fertilized. Just make sure to keep them moist and get plenty of sunlight (but don't expose them to direct sunlight).

Placement

When caring for petunias in summer, it is suitable to place them on a balcony facing east or north and provide good sun protection.

Precautions

When the temperature reaches above 30℃ continuously, petunia will grow poorly and may die physiologically. This phenomenon occurs in spring-flowering petunias and newly planted seedlings in May and June, as they are unable to withstand high temperatures.

Therefore, if you are in a high temperature area and do not have cooling facilities, it is not recommended to plant petunias in May, June and summer!
