A Detailed Guide to Selecting Dahlia Seeds and Seedling Cultivation Methods

Dahlia is also called Dahlia pinnata, tianzhu peony, dongyang chrysanthemum, dahlia chrysanthemum, etc. It has a wide variety of flower colors and gorgeous flower forms, and is one of the world's famous flowers, cultivated in many countries. So if you want to grow dahlias, how should you select seeds? What seedling cultivation methods are there? Let's find out below.

How should you select dahlia seeds?

1. Seed appearance

When selecting seeds, choose plump, round ones with a slight luster; such seeds are healthy. This is generally true for seeds, except for some very small seeds, but you should still choose plump, larger ones. You can soak the selected seeds in water; generally, the ones that sink to the bottom after being placed in are good seeds, while bad seeds will float to the surface.

2. Production date

Whether buying seeds from a seed shop or online, you must clearly ask about the seeds' production date and shelf life. Otherwise, if you buy expired seeds, the germination rate will be very low, and if they have been stored too long, they may have deteriorated. This is not conducive to germination and growth.

3. Purchasing channels

If buying online, please choose a quality seed shop with a good reputation. You can first look at other people's reviews. Be careful not to buy fake seeds. Nowadays, some people online sell fake seeds for profit. If buying from a seed shop, pay attention to making comparisons.

What seedling cultivation methods are there for dahlias?

1. Seed sowing and seedling cultivation

The seed sowing method is used relatively often when growing dahlias. Sow some relatively plump dahlia seeds on the soil in March to April; then cover them with a thin layer of soil 0.5 cm thick, and then water them thoroughly so the soil remains moist. Sprouts can grow in about a week; be careful not to let them be exposed to strong direct sunlight.

2. Cutting method

Choose fertile, loose soil and carry out cuttings in summer. First remove the dahlia side branches, keeping 3 nodes; insert 2 nodes underground and leave 1 node above ground. After cutting, water immediately. Dahlia cuttings generally take root in 3 weeks.

3. Division method

The method with the highest survival rate for growing dahlias is division, and it is also relatively simple. Divide the dahlia's tuberous roots, making sure that each division has 3 crown buds; without crown buds, new plants cannot grow. Then grow them in pots or in the ground. Water after planting, and when watering, follow "water when dry, stop when wet"; it should not be too dry, nor should there be standing water. Sprouts can grow in a week.

Dahlias have a great many varieties, with brilliant flower colors and diverse flower forms, and they are relatively easy to care for; they can be grown in both the south and the north. When growing dahlias, you must use loose, well-draining soil, as they are very afraid of standing water. In addition, pay attention to giving them more sunlight and keeping the environment ventilated. After dahlia flowers fade, remove the spent flowers promptly; this allows dahlias to keep blooming through spring, summer, and autumn.
