How to Plant Petunias
Are you wondering how to plant petunias and an introduction to the planting time and methods? Next, the editor of this site will introduce them to you.
When to Plant Petunias
It is generally recommended to sow petunias in spring and autumn, mainly in June to July in spring and October to November in autumn, which allows the seeds to germinate smoothly. When sowing, control the surrounding temperature between 18 to 25°C, provide a mixture of cultivation soil, humus soil, and fine sand, water and keep moist, and the seeds will germinate in 3 to 7 days.
How to Plant Petunias
1. Seed Treatment: Before planting petunias, the seeds need to be treated by selecting full, high-quality seeds, soaking them in water, cleaning them, and then sowing them.
2. Soil Preparation: During the planting process, suitable loose soil should be prepared for petunias, which can be mixed with 4 parts garden soil, 4 parts peat soil, and 2 parts decomposed pig manure.
3. Sowing Seeds: The soil should be watered first to make it moist, then the seeds are scattered on the soil, covered with a layer of fine sand, and then covered with straw matting for insulation.
4. Germination Care: Generally, the seeds will germinate after a week. At this time, remove the covering material, place the seedlings in a shaded area for care, and water moderately.
How to Plant Petunias After Buying
1. Inspection: When you buy petunias, you need to check the condition of the plant first, looking for any dried or yellowed leaves, which should be pruned if found, and then potted.
2. Soil: When repotting newly bought petunia seedlings, it's best to apply a thin layer of fertilizer at the bottom of the pot.
3. Temperature: Petunias thrive in a warm environment, preferably with a growth environment of about 20°C and good ventilation.
4. Watering: After buying petunias, do not water too much, just keep the soil slightly moist.
5. Light: Petunias enjoy sunlight, but when they are first bought and not yet adapted to the new environment, they should be placed in a shaded, well-ventilated area for care.
6. Fertilizing: When petunias are first bought, there is no need to fertilize to avoid fertilizer damage that may affect the roots of the plant.
How to Make Petunias Grow Fast
1. Soil: For growing petunias, use a slightly acidic sandy loam soil that is loose and has good drainage. You can also add some perlite or vermiculite to increase soil permeability.
2. Watering: Petunias need plenty of water to grow, keeping the soil moist but not overwatering, as this can cause root rot.
3. Light: Petunias require sunlight to grow, usually kept on a balcony, but shade should be provided when the sun is strong.
4. Temperature: Petunias have some resistance to low temperatures and can grow at 5°C, but they need plenty of sun.
5. Fertilizing: Petunias need certain nutrients to grow, so fertilize regularly, once every 10 days, using slow-release fertilizer.
Important Considerations for Container-Grown Petunias
Petunias are prone to aphids. Do not use pesticides when they are found, as this may hinder their normal growth. Petunias grow quickly and need to be pruned regularly to remove long, dried, or overlapping branches.
