Painstaking care of lobelia seedlings
Millions of flower growers lament that lobelia has not only small seeds, but also quite tender seedlings. Caring for her can be problematic. This is due to surface seeding. As a result, the root system is located very close to the topsoil. Due to regular or abundant watering, water in densely planted areas begins to stagnate. This, in turn, leads to the defeat of the shoots with a black leg. Such painful specimens develop poorly, infect neighboring seedlings and eventually die. To protect your crops from such a fatal outcome, it is worth learning some technologies for caring for fragile seedlings.
Daylight hours are very short in February or March. For the full growth of seedlings, access to ultraviolet light is required for 12-14 hours. Therefore, it is recommended to use supplementary lighting: in February - about 5-6 hours, and in March - 3-4 hours.
Luxury lobelia and its watering
It is necessary to moisturize such dense plantings in moderation. Since the sprouts are almost "microscopic", it is often difficult to calculate the amount of liquid. Therefore, experienced gardeners use 2 improvised devices: an ordinary syringe or syringe.
The latter tool is considered more effective, because it can be used to:
- moisten miniature planting aisles;
- introduce water into the lower layer of the soil substrate;
- soak peat tablets;
- create drip irrigation.
For growing lobelia seedlings, many use pallets, which are filled with liquid. It is recommended to use only settled and warm water. Growth stimulants and other disinfectants can be added to it. facilities.
Black the leg attacks the lobelia
After sowing the seeds, the container is covered with a lid. It cannot be removed for 3-5 days. The only thing that can be done is to open the shed 1-2 times a day and wipe off the condensation. After a few days, the lid is raised by 2-3 mm, leaving it in this position. Over the course of 2 weeks, this distance is gradually increased so that the seedlings get used to the usual microclimate.
However, even with such anxious care, the black leg on the lobelia can still appear. To combat it, use:
- Hydrogen peroxide (3%). For 1 liter add 2-3 tablespoons of the drug.
- Activated carbon. The tablets are ground into powder, which is then sprinkled on the planting.
- A weak solution of potassium permanganate. Bring its shade to a pale pink color.
- River sand. Before sprinkling the ground with them, it must be calcined in the oven or in a frying pan.
- Metronidazole. The solution is prepared with the calculation of 1 tablet per liter of liquid.
With these means, you can not only treat your seedlings, but also water them. Thanks to such preventive procedures, it is very easy to protect young sprouts from a malignant disease. These tips show that there are no unsolved problems. Therefore, if you look for a way out, you can always find it.
