Sowing Time and Planting Methods for Petunias with Rich Flower Colors
Petunia does not refer to a shorter variety of morning glory; they are not even in the same family or genus. Petunia belongs to the Solanaceae family, while morning glory belongs to the Convolvulaceae family, so do not confuse the two. As a hugely popular flower in recent years, petunia has been pursued by many flower lovers. Because it is not only easy to care for, but also blooms in a wide range of colors with a very long flowering period, it is an excellent decorative flower both indoors and outdoors. So when should petunias be sown? What are the planting methods?
1. When should petunias be sown?
Petunia is not demanding about its growing environment, and under protected conditions along the Yangtze River it can be sown all year round. The usual sowing times are spring sowing and autumn sowing, because petunia grows best at 18-25°C.
1. Spring sowing: spring is the most suitable season for sowing, because the temperature warms up in spring, and if petunias are sown at this time, they can bloom by summer. Of course, you can also sow some earlier.
2. Summer sowing: this season cannot be said to be unsuitable for sowing, but if you want a high germination rate, care is stricter than in other seasons, so summer sowing is generally not chosen.
3. Autumn sowing: autumn sowing is generally suitable for northern regions, because there is heating. Why is heating needed? Because autumn-sown plants only bloom the following spring, and to make it through winter smoothly, temperature must be guaranteed.
2. Petunia planting methods
1. Sowing and transplanting
Petunia seeds are very small, so when sowing, you only need to scatter them on the surface of the soil. Do not water directly; instead, use a dedicated spray bottle (generally available in shops, the small 1-2 yuan spray bottles) to spray, so that too much water does not wash them into the soil. Remember not to let the temperature get too high during the seedling emergence process, otherwise the sprouts will rot.
After the seeds germinate and grow into small seedlings (about 5 leaves), they can be moved into a larger pot for planting. For a beautiful shape, one seedling per pot is enough. Remember a few points: first, the soil in the pot should be mixed with base fertilizer; second, do not place them in direct sunlight for the first three days after transplanting, but keep them in a ventilated, shaded place; third, remember to maintain a suitable temperature throughout the growing period.
2. Reasonable watering
Petunia is a flower that likes dryness and fears moisture, so reasonable watering is very important. Seedlings rot easily if watered too much. Remember the principle of watering: water when dry, withhold when wet, and decide the amount of water based on soil moisture. During the vigorous growth period in summer, water can be appropriately increased.
3. Fertilizing
Frequent fertilizing and light fertilizing are very particular: this way you neither harm the petunia nor fail to promote its growth and make its root system thicker and stronger. Generally speaking, once flower buds appear on the petunia, do not use nitrogen fertilizer; instead, switch to foliar fertilizer. This can control the shape of the potted plant, so the plant is not thick and strong but has especially many flower buds.
At the same time, observe the color of the petunia leaves. If there is a fertilizer deficiency, the leaf color will become lighter or even turn yellow.
4. Pinching at the right time
If the petunias you planted branch slowly and grow unevenly, you must fine-tune the shape of the whole petunia plant by pinching. Of course, if water and fertilizer are well controlled during the seedling stage, pinching is not necessary.
5. Pest and disease control
The most common problems on petunia are leafminer flies and whiteflies. Generally, using a bit of Huhuashen will take care of it. If control is not effective, it is recommended to consult a professional.
The above is an introduction to the sowing time and methods for petunias. Petunias are not only easy to plant and care for, but their flowers are also very beautiful in shape and color, making them a great choice for indoor flowers. Flower lovers, hurry up and plant them.
