Lobelia Seed Planting Method and Blooming Period Length

Lobelia is a plant that many people know about, and it is liked by a great many people. So what is the planting method for this lobelia? How long is the blooming period:

Lobelia seed planting method:

1. Propagation

Note that lobelia seeds are very small, so when sowing you can mix in some fine sand before sowing, or first raise seedlings until they have 6-8 true leaves, then transplant them into pots or cultivate them in flower beds; use a fine-holed watering can to water, and the force must never be too strong, to prevent the seeds from being washed away. Seeds can germinate 20 days after sowing at a temperature of 22°C. They are generally commonly used as potted plants and hanging basket plants or mixed with other flowers. The plants grow slowly, and the seeds are very small; no covering is needed during germination. They are not suited to high temperatures and grow better at 12-15°C. They can bloom 14-15 weeks after sowing. Generally sow 8-12 seeds per hole.

2. Fertilizing

At the same time as planting, add a slow-release fertilizer, then topdress again about every three weeks. Especially before the blooming period arrives, supply a relatively larger amount of phosphorus fertilizer to promote flowering.

How long is the lobelia blooming period:

Common lobelia sowing times include spring sowing (around March; if conditions allow, it can be moved earlier to winter) and autumn sowing (around October). Because temperature control is now relatively easy, lobelia sowing time is also relatively flexible. The natural blooming period of lobelia is July-September, and it takes 3-4 months from sowing to flowering.

Lobelia sowing germination time: about 15 days;

Lobelia sowing soil covering: light is required for germination, do not cover; after sowing, provide shade and avoid direct sunlight;

That is all for the introduction to lobelia seed planting methods. Pay attention to the flowering time, and do not miss the flower-viewing season.

Lobelia Planting Method

    A perennial herb cultivated as an annual, it needs long-day and low-temperature conditions to bloom. Its cold tolerance is not strong, it dislikes intense heat, and it prefers loose loam rich in humus.

    Lobelia seeds are very small, so when sowing you can mix in some fine sand before sowing, or first raise seedlings until they have 6-8 true leaves, then transplant them into pots or cultivate them in flower beds; use a fine-holed watering can to water, and the force must never be too strong, to prevent the seeds from being washed away.

    Seeds can germinate 20 days after sowing at a temperature of 22°C. They are generally commonly used as potted plants and hanging basket plants or mixed with other flowers. The plants grow slowly, and the seeds are very small; no covering is needed during germination. They are not suited to high temperatures and grow better at 12-15°C. They can bloom 14-15 weeks after sowing. Generally sow 8-12 seeds per hole.

    During the seedling stage, pay attention to loosening the soil and weeding. Apply 1 application of dilute human manure and urine after planting; after the summer harvest, topdress 1 time with livestock manure or ammonium sulfate, urea, etc., and in winter apply decomposed fertilizer or compost. In dry seasons, irrigate and keep the soil moist economically to facilitate growth. At the same time as planting, add a slow-release fertilizer, then topdress again about every three weeks. Especially before the blooming period arrives, supply a relatively larger amount of phosphorus fertilizer to promote flowering.

When should lobelia be sown? Lobelia sowing time

Lobelia, also known as edging lobelia, is an annual herbaceous flower with a plant height of about 12-20 cm and fine, dense stems and branches. The upper stem leaves are smaller and lanceolate, while the leaves near the base are slightly larger and broadly spoon-shaped; the leaves are alternate. The flowers are terminal or axillary, and the corolla tip is five-lobed, with the lower 3 lobes relatively larger, shaped like a butterfly spreading its wings. Flower colors include red, peach red, purple, purple-blue, white, and other colors. Today the editor will mainly talk about knowledge on sowing lobelia.

Common lobelia sowing times include spring sowing (around March; if conditions allow, it can be moved earlier to winter) and autumn sowing (around October). Because temperature control is now relatively easy, lobelia sowing time is also relatively flexible. The natural blooming period of lobelia is July-September, and it takes 3-4 months from sowing to flowering.

Lobelia sowing germination time: about 15 days;

Best temperature for lobelia sowing and germination: 21-25°C;

Lobelia sowing soil covering: light is required for germination, do not cover; after sowing, provide shade and avoid direct sunlight;

After the seeds germinate, lower the moisture of the medium. 4-6 weeks after sowing, they can be planted into flower pots with a diameter of 13-16 cm. When sown under long-day conditions, three plants can be planted per pot. Under long-day conditions, the plants will not develop leaf rosetting, and in this way the flower quantity will also be correspondingly reduced.

Lobelia is a long-day plant and likes strong light. Long-day conditions (14-16 hours) can promote bud formation. Under short-day conditions, only vegetative growth can be promoted. A 10-week long-day period must be provided to promote flowering. Under short-day conditions, the plants will develop leaf rosetting and have more branching at the base. After leaf rosetting occurs, they should be placed under long-day conditions to grow, so as to promote flowering. If the plants grow completely under long-day conditions, they will bloom very quickly, will not branch, and will not develop leaf rosetting.

Key points for lobelia planting

Maintaining short-day conditions before planting can improve flower quality. If grown completely under long-day conditions, pinch the tips after planting, which can promote the growth of side buds and make the plants grow compactly. Do not let the plants suffer drought stress; maintain a sufficient water supply. The result of drought will make the flower stems bend and no longer stand upright.

Summary: The above is knowledge related to sowing lobelia. I hope it is helpful to everyone.
