Larkspur (it is also commonly used as a delphinium, or a borer) includes several hundred single and perennial plants, many of which are very decorative - the plant enters the garden culture from the 17th century, delighting with a variety of varieties and colors, as well as simplicity.
The best breeding methods for a brat - cuttings or seeds. But when dividing, the risk of injuring the rhizome is great, so if you grow varieties and delphinium hybrids that are valuable to you, it is better to practice growing it through seeds and seedlings.
Collection and storage of delphinium seeds
Delphinium seeds can be purchased at a specialty store, if you trust the manufacturer, or you can collect it yourself - if this wonderful flower is already growing on your site. The second option, as noted by experienced gardeners, is much preferable, because in case of the slightest violation of storage conditions, collection of seeds from old plants or inadequate shelf life, purchased Delphinium seeds are more likely not to grow at all, more reliable than Delphinium seedlings from their own seeds.
Mnogolistovki plants ripen in autumn (a little earlier or a little later - depending on the type and variety). "Boxes" with seeds indicate their maturity by drying and browning, and they need to be collected only in dry weather.
Even seeds collected from a healthy plant and in suitable conditions, the delphinium seeds have a “shelf life” of only 11 months, and when stored in warm, dry conditions, they generally quickly lose germination. Therefore, they should be stored in a cool place at a temperature of about 0 ° C (for example, in a paper bag on the shelf of a refrigerator).
Preparation of tanks for landing perennial delphinium
We have already written about all sorts of options for seedlings, some of which can even be done by hand.
For the cultivation of delphinium they fit all - low wide boxes, plastic pots, special cassettes. It is best to water the seedlings through the pallet, so you need to make holes in the bottom of the tanks.
An excellent choice will be peat tablets, with which you will later plant the plants in open ground, because Stirling seedlings tolerate the transplant quite painfully. It is only important to track that the peat filler is not too sour.
Remember also that the seedlings of delphiniums do not like souring the soil and a large space for the root system - therefore you should not choose the containers of too large size.
Before filling the ground, do not forget to thoroughly wash and disinfect the selected container.
- What is growing seedlings - choose the right capacityLet us examine all the containers “by the bones” and tell you why plants do not “love” peat pots and what dangers posed by seedling cassettes.
Soil preparation for growing delphinium from seeds
Selected containers should be filled with primer for future shoots (if you do not have the individual peat tablets described above), departing about 1 cm from the top edge.
For the delphinium, the soil is non-acid and light, with good moisture and breathability. For example, a self-prepared mixture of peat, sod land, humus and coarse sand (1: 1: 1: 0.5). All components are thoroughly mixed, and loosen the resulting mixture by adding a third of a glass of perlite. If you can see that the soil turns out to be too fat, you can add ground dry straw or chopped dry grass compost.
From the store options for the baler, special light soil mixtures for seedlings or soil for succulents will be suitable.
Prepared soil before filling in the tank for growing must be disinfected from possible spores of fungi and weed seeds - warm for 1 hour in a water bath and shed with a weak solution of potassium permanganate (alternatively, Fitosporin or Fundazole).
Preparation of delphinium seeds for planting
Before sowing the seeds of a delphinium, it is necessary to prepare not only the containers and the soil for them, but also the seed itself.
As you remember, after collecting, they should be kept in the refrigerator all the time. Before the sowing itself, it is necessary to conduct their disinfection. To do this, take the seeds from the container in which they were stored, and, falling asleep in a gauze bag, immersed for 20 minutes in a strong solution of potassium permanganate (or any other fungicide - Maxim, Fitosporin, etc.). After that, the bag is washed with cold running water and to stimulate growth for another day soaked in a solution Epin. At the end of the procedure, the seeds of the delphinium are laid out on a paper towel and dried.

Planting delphinium seeds for seedlings
Planning the sowing of delphinium seeds is best for the end of February.
Not very large seeds, slightly deepening, are evenly distributed over the surface of the prepared substrate as described above, and sprinkle a thin layer of soil on top (so that they do not appear on the surface during the first irrigation) and spray it with water from a spray bottle.
Stratification will help the seeds to ascend faster, so the seeded containers are covered with opaque dense material, wrapped in plastic and placed in a refrigerator, on a balcony, or taken out onto the street for 10-14 days. Seeds can easily withstand temperatures up to -5 ° C.
- Perennial seed stratification - detailed instructions with photosThe most effective ways to stratify the seeds of various ornamental crops.
The first option is preferable - it will be convenient for you to keep track of the seeds, because there are times when they begin to hatch during the process of stratification. This usually happens on the tenth or fourteenth day.
When the first shoots appear, the container should be opened and must be rearranged to a bright place with a temperature of 15-18 ° C (but in no case above 20 ° C, otherwise the shoots will die).
Care for delphinium seedlings in the first days after germination
After the first shoots appear, a period of active care for the delphinium begins.
First of all, the seedlings of this plant must be illuminated, even if it is on the windowsill. It is important to monitor the soil moisture and prevent it from drying out - watering at the root (you can do this with a syringe) should be moderate, but sufficient. The soil on the surface of the pot should always be loose and moderately wet.
Do not forget about the temperature, it is necessary that the air in the room does not exceed the mark of 20 ° C.
As soon as the real first 2-3 leaves appear, the delphinium sprouts should be uncaused in a container of at least 300 ml. Plants in this process are buried in the soil to the point of growth of these leaves.
- Sowing a seedling - what is it and why is it needed?We answer the questions of beginners, what is the need for plant picking and when it is better to carry it out.
A couple of weeks before planting a delphinium into the ground, it is advisable to feed it with Agricola or Mortar (combining top dressing with watering), and also to harden gradually, occasionally bringing it to fresh air and gradually increasing these time intervals.
In the open ground grown delphinium seedlings are planted in the second half of May, when the earth warms up, and the threat of return frost finally passes. Young plants necessarily pritenyuyut and carefully preserve against pests (especially love to eat slugs seedlings).
With proper further care, you can expect the first flowering of a seed-grown delphinium by the end of August.
Growing delphinium seedlings from seeds at home is a great way to ensure healthy and strong plants. And although it is necessary to tinker a little with the germination of seeds, the large, bright, exclusively elegant candles of this plant will pay off all your efforts a lot in the future.
