Everyone knows that perennial dahlias are grown from tubers. This method involves certain efforts associated with the digging and storage of rhizomes. In the spring, these tubers must be sorted, separated, and again instilled in the ground. Therefore, many growers prefer to grow annual dahlia varieties. Thus, every year it is possible to plant flowers of different varieties and colors. Most of them collect the seeds themselves, and in spring they germinate them for planting. You can, of course, just sow dahlia seeds immediately in a flower garden, but then flowering will begin only at the end of summer. So let's take a look at how to prepare dahlias for seedlings, as well as how to grow and leave dahlias from seeds. Many are interested in when to plant seedlings, and how to do it correctly. You will see the answers to these questions below.
First you need to know that the cultivation of annual dahlias is divided into the following stages:
- Collecting seed.
- Sprouting dahlia.
- Care for seedlings.
- Planting flowers in the ground.
But if you grow dahlias for the first time, you should consider which varieties are best for you. In 2019, seedlings of stunted dahlia are often purchased for seedlings. Such flowers can be grown even in apartment buildings. It became very popular to plant dahlias in his balcony. If you have a flower bed, then medium-sized dahlias that grow no higher than 60-65 centimeters will be an excellent option. There are varieties that reach up to one and a half meters in height. In general, the choice is huge, and everyone can choose dahlias to their liking.
Attention! The lower the dahlia bush, the earlier the flowering will begin. So, if you buy low-growing varieties, then already two months after the germination of seeds, you can admire the first flowers.
Very often on the shelves of flower shops you can find a mixture of seeds. In these packages are placed the seeds of the same sort of dahlia, but in different colors. Such bright combinations will make your yard colorful, and every time they will cheer you up. And considering that dahlia blooms for a very long time, you can enjoy such beauty even after the other flowers in your garden are already withered.
For those who are already growing dahlias, it will be easier and more economical to harvest seeds on their own. They are collected from fully dried flowers, and stored until the beginning of spring in paper envelopes. The only drawback of this method is that annual dahlias quickly degenerate, and the seeds may lose their properties over time. So from time to time it is necessary to change the seed.
The first step is to prepare the ground for sowing seeds. Begin preparation in the fall. For this perfect humus, turf and sand. Peat can also be used instead of humus. All components are taken in an equal amount, and mixed until a homogeneous state. Next, sow the mixture through a sieve to separate the stones. After that, the soil should be heated in the oven and treated with a solution of manganese, it will help get rid of diseases and pests. The seeds themselves do not need to be processed.Attention! You need to start sowing dahlias in the first week of April.
For dahlia seedlings suitable low boxes with drains for excess fluid. Half of the tank is filled with prepared soil. Before sowing the seeds, the soil must be moistened with a spray. Then the seeds are sown at a distance of 3 centimeters from each other. The depth of the hole should be no more than 2 centimeters. Immediately after that, the planted seeds are placed in a warm place with good lighting, the air temperature should be around +25 ° C.
Important! Before the emergence of shoots boxes must be covered with foil.
The first shoots should appear already after 5-10 days. Now that the sprouts have sprouted, you need to remove the film from the boxes, and again leave them in a sunny place. In case of insufficient lighting, the shoots will be pulled out. During this period it is very important to monitor the level of humidity. The soil should not dry out, but at the same time a large amount of moisture can lead to diseases and destroy the seedlings. It is better to water the dahlia with a spray bottle.
Start picking should be after the appearance of three or four leaves. You can move sprouts into separate disposable cups or other containers convenient for you. They need to be filled with soil from the box in which the seedlings grew. At the bottom of the cups you need to make a hole so that excess liquid can flow.Important! Do not pull plants out of the box. It is necessary to carefully dig a sprout together with the surrounding soil. This will help the seedlings quickly settle on the new place.
Healthy and strong seedlings are much easier to transfer planting in the ground, and will also grow well and bloom quickly. For this it is necessary to provide her with appropriate conditions and care. Probably the most important thing for seedlings is good lighting. In case of bad sunlight, the shoots become too thin and stretch out. It is also necessary that the room with the seedlings is well ventilated. But it is important not to overdo it and prevent drafts.
Do not forget about regular watering seedlings. The soil should not dry out, so you need to constantly monitor the level of humidity. It is necessary to make watering only on demand, if you see that the soil begins to dry out.
It is advised from time to time to feed the seedlings with special complex fertilizers. The first feeding can be done only two weeks after the pick. The following procedures are performed every seven days.
In early May, you can begin hardening plants. It is necessary that the seedlings get used to temperature extremes. The first time dahlias take out to the street or balcony for five minutes. Every day time needs to be increased.Tip! If the air has not warmed up to a temperature of +13 ° C, do not rush to quench. Too low a temperature can ruin tender shoots.

Then in June, the plants will begin to bloom and please the eyes of others. In the northern regions, the best time will be the second decade of June. The main thing is that the soil is well warmed. Since, every year, spring can present its surprises, you shouldn’t strongly focus on any dates. The time when planting seedlings comes from the moment the frost stops completely.
Tip! If frosts unexpectedly return, it is necessary to cover dahlias with geotextiles for the night.
How to plant dahlias

As a result, the flowers will be very small, and the bushes will look unhealthy. A place for flower beds should not be in-depth, so that water does not stand there. It is better to plant dahlias on the hills, this will help protect them from frost. Dahlias grow well in soil with a slightly acidic or neutral composition.

This method takes a little time, but allows you to keep the root system safe and sound. Due to injuries, the plant can not settle down in the open field.
Planted seedlings should be at a distance of about 20 centimeters, if we are talking about stunted varieties. Between the bushes of medium size leave about 50 centimeters, and between tall plants - about 70 centimeters. As a fertilizer in the hole you can put humus or wood ash.
The land around the bushes is mulched, it will protect the plants from the cold, and will not allow the flower bed to overgrow with weeds. All of these steps will help dahlias grow quickly and start blooming.

If it rains at this time, then even less.Attention! Dahlia bushes can be watered only in the evening or in the morning.
Feeding is advised to be held every 2 weeks. Before flowering, only organic fertilizers can be applied, for example, mullein infusion. In a bucket of water, add 1 liter of mullein, and water the dahlias. One bush will need 1.5 liters of infusion.
