How to plant petunia? Planting time and method

Petunia planting time

Petunia is generally sown in spring and autumn, mainly in June to July in spring and October to November in autumn, so that its seeds can be sown and germinated smoothly. When sowing, the surrounding temperature should be controlled between 18 and 25°C, and it should be provided with a soil mixed with equal amounts of culture soil, humus soil and fine sand. Water it to keep it moist, and it will germinate in 3 to 7 days.

Petunia planting method

1. Seed treatment: When planting petunias, you must first process their seeds. Select high-quality, full seeds, soak them in water, and then you can sow them after cleaning.

2. Prepare the soil: During the planting process of petunia, it is necessary to prepare suitable loose soil for it. You can choose to mix 4 parts of garden soil, 4 parts of peat soil and 2 parts of decomposed pig manure.

3. Sowing seeds: Water the soil first to make it moist, then sow the seeds on the soil, cover it with a layer of fine sand, and then cover it with a straw mat to keep warm.

4. Germination and maintenance: Generally, it will germinate after a week. At this time, you need to lift the covering, and then place it in a scattered light place for maintenance and water it appropriately.

How to plant the petunia you just bought

1. Inspection: When you buy petunias, you need to check the condition of the plant first to see if there are any dry or yellow leaves. If so, you need to trim them off and then put them in the pot.

2. Soil: When repotting newly purchased petunia seedlings, it is best to apply a thin layer of fertilizer at the bottom of the pot.

3. Temperature: Petunia grows well in a warm environment. It is best to provide it with a well-ventilated growing environment at around 20°C.

4. Watering: Do not water the petunia too much after you buy it. Just water it appropriately and do not let the soil dry out.

5. Light: Petunia likes light, but when you first buy it, since it has not yet adapted to the new environment, you need to place it in a shaded, ventilated place for maintenance.

6. Fertilization: When you just buy the petunia, you don’t need to apply fertilizer to avoid fertilizer damage, which will affect the roots of the plant.

How to grow petunia quickly

1. Soil: Petunias can be grown in loose, well-drained, slightly acidic sandy soil. At the same time, you can add some perlite or vermiculite to increase the permeability of the soil.

2. Watering: Petunia needs sufficient water to grow and keep the soil moist, but do not water too much, which will cause root rot of the plant.

3. Light: Petunia needs light to grow. It can be grown on the balcony at ordinary times, but when the sunlight is strong, it is necessary to provide shade.

4. Temperature: Petunia has a certain ability to resist low temperatures and can grow at a low temperature of 5°C, but it needs more sunlight.

5. Fertilization: Petunia requires certain nutrients to grow, so it needs to be fertilized regularly, once every 10 days. You can use slow-release fertilizer.

Precautions for petunia pot cultivation

Petunias are prone to aphids. Do not spray them with pesticides after discovering them, so as not to hinder their normal growth. Petunias grow quickly, so it is necessary to prune overlong branches, as well as old and overlapping branches.
