Dahlia is a particularly charming ornamental flower, with very large tubers at the base of its rhizome, making it suitable for planting in the garden. It has tall stems that can maintain growth for many years, and with proper care, it can produce flowers more beautiful than sunflowers every year. It has many varieties with rich colors and various flower shapes.
After the dahlia flowers bloom, they can be cut and turned into cut flowers, which are even more beautiful than sunflowers. Dahlia has over 20,000 varieties and is a flowering plant native to Central America, always being the focus of flower exhibitions.
The dahlia flowers can be seen from summer until frost, with particularly attractive colors, making them very suitable for planting in the garden. Dahlias are quite picky about the environment and soil, preferring more sunlight, with a well-ventilated and well-lit care environment, but avoiding strong winds.
When planting dahlias, it is necessary to maintain an appropriate spacing; they should not be planted too densely, or their tubers will grow together, affecting flowering.
Dahlia is a perennial plant, but if the winter is too cold, its tubers need to be dug up and replanted when it warms up in the spring. If you live in a warmer winter area, you can leave it in the garden.
Is the dahlia a perennial plant?
Dahlias are propagated by tubers, not bulbs, and they are not cold-resistant. The minimum care temperature in winter should be maintained above 6 degrees, or they may freeze easily.
Dahlia tubers should be dug up, dry branches and leaves cut off, and placed in a warm, dry, and shaded place until it warms up in the spring, ensuring that dahlias bloom every year.
Dahlias also have different varieties with varying cold resistance. If you live in a colder winter area, you can choose dahlias with some cold resistance.
The cultivation environment for dahlias must have ample sunlight, maintaining more than 8 hours of direct sunlight per day to grow well. In hotter climates, they need to be shaded in the afternoon during the summer.
The soil for planting dahlias should be rich in humus, loose and breathable, with good drainage. Using neutral sandy soil for cultivation is a good choice.
Some peat soil can be mixed into the soil, with an appropriate addition of perlite to maintain water retention and prevent waterlogging in the pot. During the dahlia growing season, the soil should be kept moderately moist and avoid excessive drought.
