How to cultivate potted dahlias
The editor introduces how to cultivate potted dahlias and the green plant flower planting content related to the home care skills of dahlias. Let's share the detailed content next.
Dahlias are also called dahlia flowers, peony flowers. The flowers of this plant are large, with the largest flower diameter reaching over 20 centimeters, and a single flower can even be larger than a face. The colors are also very rich, including red, yellow, pink, and many other colors. The blooming period is relatively long, lasting from May to October. Today, let's talk about how to care for potted dahlias in spring.
1. Supplement lighting
Among many flower varieties, dahlias are moderately fond of sunlight, enjoying ample light most of the year, only needing appropriate shading in summer.
In the early and middle stages of spring, the sunlight is very gentle, and there is no need to worry about the plants getting sunburned. You can boldly place the flower pot in a sunny location such as outdoors, the south balcony, or near the window. Try to let the dahlias get more sunlight, which is more conducive to growth, and the number and quality of flowers in spring will also significantly improve. In the late spring, as the weather gradually approaches summer and the UV rays become stronger, it is necessary to provide appropriate shading for dahlias and avoid the strong midday sun. In the transition period from spring to summer, move the flower pot to a place with scattered light to avoid direct sunlight.
2. Watering
The root system of dahlias is like small sweet potatoes, storing a large amount of water, so the plants have strong drought resistance and do not require frequent watering. Before watering potted dahlias each time, lift the pot to check its weight. Only water when the pot feels light. If the pot is still heavy, it means there is still a lot of water inside, so there's no need to water.
3. Supplement fertilizers
Dahlias grow quickly in spring, and with their long blooming period, their demand for fertilizers is higher than that of most other flowers. Regularly supplementing nutrients with fertilizers will make dahlias lush and continuously blooming in spring.
From February, dahlias can start being fertilized after the seedlings sprout from the soil. Prepare some well-rotted organic fertilizer, and buried a small amount in the soil, using it once a month before summer arrives. When the branches produce flower buds, add some phosphorus and potassium fertilizers, such as monopotassium phosphate, Flower多多 No.2, etc. Mix the fertilizer according to the instructions with water to make a fertilizer solution, pour it at the roots of the dahlias, once every 10-15 days, and stop fertilizing immediately after the flowers bloom.
4. Control temperature
Compared to ground-grown dahlias, the biggest advantage of potted dahlias is that you can control the temperature by moving the pot. The most suitable growth temperature for dahlias is about 20 degrees Celsius, and they are not resistant to high or low temperatures. In early spring, if there is a sudden drop in temperature called "late spring cold," promptly move the pot to a warm room to avoid freezing the dahlias; high temperatures can also inhibit their growth. In summer, try to place the pot in a cool semi-shaded area. By adjusting light and temperature, you can make dahlias grow lush and extend their blooming period.
