How many days does Lobelia take to germinate? There is a trick to how often to water it
Lobelia is a flower introduced into China from abroad, and it is now distributed in many places across the country. Lobelia has a beautiful appearance and blooms small purple flowers, which is why it has attracted many people to grow it. During cultivation, many people do not know how to water it, but once you master the technique it is actually quite simple.
How many days does Lobelia take to germinate
Lobelia seeds sown at 22°C can germinate after 20 days, and can bloom 65 days after sowing.
How often should Lobelia be watered
During the growing period of Lobelia, it can be watered once every 7 to 10 days. When watering, water thoroughly, basically following the principle of watering thoroughly after the soil has dried out.
How to pot up Lobelia
1. Prerequisites. Before planting Lobelia into its final pot, it should be noted that its seedlings should have grown in a temporary pot for a period of time and developed a good root system before they can be planted out. Choose a suitable flowerpot; you can grow a single plant or plant several Lobelia together. For the soil Lobelia needs, you can choose one with relatively good drainage and add a suitable amount of base fertilizer, then the seedlings can be lifted and planted out.
2. Method. Take the Lobelia plant out of the temporary pot, preferably with soil around the roots, and the soil should preferably remain in a loose root-ball state, so that damage to the roots can be greatly reduced. Then plant the Lobelia into the new flowerpot, taking care to firm the soil. After potting up the Lobelia, water it once with settling water first, then place it in a cool place to recover. After recovering, the Lobelia can be considered established, and normal care can then be carried out.
3. Care. After potting up, once the root system of the Lobelia is stable, normal care can begin. At this point, watering and fertilizing should reasonably meet the growth needs of the Lobelia. Basically, the main task at this time is pinching to control the plant shape of the Lobelia and make it bloom more. In winter, take care to protect the plant from freezing, and stop water and fertilizer.
How to fertilize Lobelia
1. Choice of fertilizer. In the early stage, some slow-release fertilizer can be used, applied once every 20 days. But when it is about to bloom, apply an additional fertilizer with a higher P content, so that the flowers can bloom better. For base fertilizer, you can generally choose a low-strength multi-functional fertilizer of the bud type, and later consider adding liquid fertilizer. In winter, when the weather is colder, the amount of fertilizer required is generally smaller. Especially when the temperature is particularly low, you can consider stopping fertilization, and continue fertilizing after the temperature warms up again. During their harvest season, fertilizer should also be applied appropriately. In general, some organic fertilizers such as human and animal manure can be applied in summer, and a little half-rotted fertilizer can be used in winter.
2. Fertilization method. If cultivating this flower in spring, fertilization should begin at this time, but note that the amount should be moderate. Do not fertilize Lobelia too frequently; generally, spraying with liquid fertilizer once a week and watering thoroughly is enough. When planting, some base fertilizer can be applied to ensure sufficient nutrient supply in the lower layer of soil, and fertilizer can be added appropriately.
3. Precautions for fertilization. In the first stage of Lobelia growth, from the embryo developing well and breaking through the seed coat, to the young roots sprouting and emerging from the soil, and then to growing leaf after leaf, the Lobelia is at its most delicate at this time and needs special attention. The temperature must be controlled at 15-18°C, and the soil should be kept slightly moist but not too wet. It is generally recommended to use mainly sandy soil with good drainage, and the clay content in the substrate should be about 15 percent. When fertilizing Lobelia, proportions are needed; generally, 1 kg to 1.5 kg of complete balanced fertilizer should be applied per cubic meter of soil, along with 2 kg to 3 kg of slow-release fertilizer.
If you want Lobelia to germinate quickly and grow well, you must control its temperature; it can only grow well at a suitable temperature. As for watering, generally watering about once a week is best, but there must not be standing water. The growth of Lobelia is also inseparable from fertilization. The specific fertilization methods are introduced above, and everyone can take a look.
