How to plant bulbs and flowers can be propagated and sown in separate roots.

In our common flowers, many have a seed ball, as the name implies, the ball means that its root is as long as a ball, this is because its root abnormal expansion, from a fine root to a nearly circular bulb. This bulbous plant is divided into many varieties, among which we are more common, such as daffodils and lilies, but do you know how this plant propagates?

1. Split the root

For this kind of plant, the more common way of reproduction is to separate new plants from the roots. After this plant grows for a certain period of time, its root is no longer a seed ball, but grows a lot of small balls, at this time friends carefully break off these balls, you can grow more plants.

2. Cuttage

For this kind of plant, it can also be propagated only by cutting. Friends first cut the flowering branches into segments, be careful not to be too long, and then insert them into a soft matrix, or peel off the scales on the stem and bury them in the fine sand, and soon they will be able to grow new bulbs.

3. Sowing seeds

This method is suitable for almost all plants, and this kind of plant is no exception. Before formally sowing, pick out a full spare, then prepare a basin of nutritious soil, sow the picked seeds, and then sprinkle a very thin layer of soil. As for the supply of water, the soil can be soaked in a basin before sowing, or it can be sowed before sprinkling water.

All of these methods can breed new seed balls, but it is difficult to grasp the temperature. Friends can try it first.

Propagation method of Iris flavescens: ramet, sowing and bulb

Yellow iris is a kind of perennial herbaceous plant, the flower is yellow, it is very beautiful when it blooms, the flower contains 2 flowers, the flowering period is from May to June, we can see the figure of yellow iris in hillside grass and forest edge grassland, it has high horticultural value, the following is to learn about the breeding method of yellow iris.

Propagation method of Yellow Flower Iris 1. Ramet of Yellow Flower Iris

Ramet propagation is generally carried out every 2 to 4 years, in spring, autumn or after anthesis. Iris splits after anthesis (to avoid the rainy season). The flower buds can differentiate well before winter and blossom the following year. It is better to have 3 to 4 buds when dividing the rhizome. If the ramet is too small, it will affect the flowering of the following year. In ramet propagation, the upper leaves of the plant should be cut off and left about 20 cm for planting. Most varieties of Iris are suitable for shallow planting. The planting spacing varies according to the species, the strong species is 50 × 50 cm, and the general variety is about 20 × 20 cm.

A, applying sufficient basal fertilizer, the soil should keep high humidity during the growing period, especially at the flowering stage, the roots should grow in water, and the water depth 5~7cm is suitable.

B. Soil pH planting should be below 6.5. otherwise, the plant will grow slowly and yellowing may occur.

C. fertilize for 3 to 4 times during the growing period, and pay attention to the removal of weeds and withered yellow leaves. Summer high temperature, should often spray water to the leaf surface, increase air humidity, make seedling strong leaf green.

2. Sowing seeds of Iris flavescens

If the seed is used for propagation, it should be carried out immediately after the seed is mature, so that the seed is easy to germinate and can blossom in 2 to 3 years. Pot sowing from March to April, the optimum temperature for germination was 18-21 ℃, germinated 15-20 days after sowing, and transplanted when the seedling was high 5~6cm.

3. Iris flavescens bulb

After a year of planting and flowering, a seed ball will run out of nutrients and produce new roots, and there will be many bulbs around the new bulb, which can develop into a flowering ball after one or two years of planting. The world flower planting experts carry out tissue culture of axillary buds, bulbs, stem plates, flower stems and other different organs of Iris bulb to make it grow new bulbs, which provides a new way to accelerate propagation and cultivate disease-free strong mother balls.

Flowers suitable for sowing and propagation in May, and it is not too late to grow flowers in May.

May is coming, and many flower lovers think that they have missed the best time to sow flowers, so they give up your side of planting and cultivating flowers. In fact, this is not necessary. Now there are succulent flower beds for everyone to summarize the flower planting in May.

The climatic feature of May is that the temperature continues to rise, and the rainfall in our country increases gradually from south to north. After each fall of Rain Water, the temperature increases obviously. The weather with many spring rains turns to muggy after the spring rain of Lesser Fullness of Grain ends, which marks the beginning of summer soon.

Therefore, May at the turn of spring and summer is a key period for growing flowers, which plays an important role in laying the foundation for the growth of potted flowers in summer and autumn.

Species of flowers and trees suitable for courtyard display

In May, at the turn of spring and summer, temperatures rise sharply across the country, and the sun is getting stronger and stronger. More species of potted ornamental plants can be displayed in the courtyard Such as rose, Nanyang fir, Tripterygium, Canadian jujube, rubber tree, five-needle pine, Luohan pine, southern bamboo, Zhu Dinghong, jasmine, palm bamboo, cycad, king coconut, sunflower, mottled clover tree, palm, wine bottle coconut, cinnamon, beautiful needle sunflower, European spring, lily, dwarf pot, pomegranate, peony, Michelia, red maple, Milan, four seasons cinnamon, daidai and so on.

Breeding of courtyard flowers:

1. Sowing seeds

Woody flowers are loquat, star anise gold plate, broad leaf ten meritorious work, loose tail sunflower, wine bottle coconut, sweet-scented osmanthus. Among them, the seeds of the first five kinds of flowers can be sowed as they are picked, but the fruits of sweet-scented osmanthus, which are blackened, softened and whitened, should be stored in clean wet sand until February next year, and then sowed when the seeds are white.

When picking and sowing seeds, we should pay attention to the following points when sowing: first, to keep the seedbed moist, but not stagnant water; second, to cover the grass to prevent the seeds from "budding"; and third, to remove the covered grass 2 to 3 times after seed emergence, and set up a shed in time to shade the young.

In addition, although loquat is a large seed, but its bud top soil ability is weak, easy to bend, sowing too deep will affect the emergence rate and seedling rate, so it is appropriate to shallow sowing, generally ditch depth of 2 to 3 cm to cover soil to ditch full.

At this time, gladiolus bulbs planted in the ground can blossom in August. The evening jade planted in the ground can blossom from August to September.
