How to grow a rootless cactus, and how to grow a rootless cactus?

Stick it in the dirt, water it regularly, and it will grow roots.

Stick it in the soil and keep it dry, because if the soil is too wet, it will rot.

Cactus. itself has.

Regenerative ability. Succulent stems.

Under the right conditions, it can grow by roots.

Give it a try with tissue culture.

1. Cutting time.

Under normal conditions, monthly cuttings are most suitable. There are greenhouse conditions and can be carried out all year round.

2. Preparation of matrix.

Cacti are resistant to drought and barrenness, and avoid stagnant water. Therefore, the substrate must have good air permeability, good drainage performance, and can keep wet, with vermiculite and perlite as well. Coarse river sand can also be used:

Loam: Leaf decay: chaff ash 4:

Formulated with 3:2:1.

3. Cut cuttings.

Robust and mature stem nodes were selected from the mother plants with strong growth and no diseases and insect pests as cuttings. Cut cuttings with a rust-free, alcohol-sterilized knife.

4. Dry cuttings.

The cuttings should not be cut immediately, they should be placed in a dry room for 5-7 days, and the cuttings should be taken only after the incision is dry and the stem flesh begins to shrink.

5. Hormone soaking.

For varieties that are difficult to root, soaking the base of cuttings with plant growth hormone can greatly improve the survival rate. Method: Dip the base of the cuttings with a 50 to 100 ppmggr (plant growth regulator) solution for 1 h, or dip the base of the cuttings with 200 ml of naphthalene acetic acid solution for 4 h.

Most other varieties that are easy to root can be cut without hormonal treatment.

6. Cuttings. The base of the cuttings should be buried shallowly in the substrate, and it should not be too deep to cause rot. Cuttings are soft and difficult to stand upright due to drying, so they can be laid flat on the substrate; It can also be supported with small wooden sticks, and then gently press the soil on both sides of the cuttings with both hands to make it close to the soil.

7. Post-plugging management.

The first is moisture management. When cuttings, the substrate should be moist, too dry and not easy to take root, you can pour less water from the edge of the pot. However, the substrate should not be too wet, otherwise it is easy to cause rot of the cuttings.

Before rooting, keep the potting soil moist at all times. To reduce water evaporation, a plastic bag can be used to cover the basin. The cuttings will take root in about a month, at which point the plastic bag should be removed immediately.

The second is light management. Before rooting, it should be protected from sun exposure and should be maintained in a semi-shaded place. After rooting, aspects such as moisture and light can be routinely managed.

The height of the soil is generally one-quarter to one-fifth of the height of the sphere, and it should not be too deep.

First of all, treat the wound, you can stain some plant ash for disinfection and sterilization, and then place the plant in a cool place, put it for a few days until the wound is completely dry, you can plant, do not plant the wound before it is dry, so it is easy to make the plant infected, rotten, and difficult to feed.

Prepare the container and nutrient soil in advance, the container is suitable for choosing a suitable size, loose and good air permeability and drainage, bury the cactus sphere in the soil, the depth is about a quarter of the sphere, fix the plant, do not rush to water it first.

It is best to wait until there are small roots in the roots before giving a little water, and when watering, be careful not to let the spheres get watered, generally do not water directly from above, but pour an appropriate amount in the soil near the plant. Place the plants in a well-lit and well-ventilated place, and wait about a month for new roots to take place under normal management.

Four-season maintenance. 1. Spring:

The outside temperature is not high, try to water as little as possible, watering should be appropriate, and the temperature should be appropriate.

2. Summer: The sun is hot in summer, the temperature is strong, and too much watering will rot the roots, which will affect its ornamental value. Spray frequently and increase humidity appropriately.

3. Autumn: The cacti in autumn have begun to flourish, and the crisp weather in autumn naturally requires more water and fertilizer and more watering.

4. Winter: Most of the cacti have entered the dormant period, in this dormant state, only need to keep the moistness of its potting soil, too much watering may cause the decay of the cactus.

1. Drying: When planting cacti without roots, it needs to be placed in a ventilated place to dry for 3-5 days. 2. Soil:

Sand, vermiculite and pastoral soil are used to prepare the cultivation substrate. 3. Cuttings: Shen Jian inserts the rootless cactus into the soil and waters it again.

4. Maintenance: control the ambient temperature at 20-25 to promote the rapid rooting of cactus in cruise pants.

1. Drying treatment

When planting cacti without roots, it needs to be placed in a ventilated and breathable semi-shaded environment to dry for 3-5 days, so that a layer of film grows at the bottom of the cactus, and rooting powder should be applied to the bottom of the cactus to improve the cell vitality of the plant and make it easier for the cactus to grow roots.

2. Soil conditions

Cactus is suitable for growing in loose and breathable sandy loam soil, when planting cactus, it is necessary to use garden soil, sandy soil, vermiculite in a ratio of 3:1:1 to mix and prepare a cultivation substrate, and then apply rotten cake fertilizer or compound fertilizer to the soil to improve the fertility of the soil and promote the rapid growth of cactus.

3. Cutting method

When propagating cacti by cuttings, you need to insert the plant into the soil, and then press the soil tightly with your hands to prevent the cactus from lodging, and then water it once, so that the water can flow down from the edge of the pot, so that the soil is completely soaked, and the cactus should be moved to a place where the light is scattered, so as to promote the vigorous growth of the plant.

4. Suitable temperature

Cactus likes warmth, when breeding cacti, you need to control the ambient temperature at 20-25, to provide a suitable environment for the growth of plants, and to control the frequency of watering, it is best to wait for the soil surface to dry completely before watering, keep the soil slightly moist, so as not to rot the roots of cactus.

Before planting, the roots can be properly pruned, and then the wound can be smeared with an appropriate amount of plant ash for sterilization and disinfection, and after the cactus roots are dried, they can be planted in loose and fertile soil and moisturized with soil. Before potting, a small layer of tiles is laid at the bottom of the pot, and then the wounded part of the cactus is buried in the soil at a depth of about a quarter, and after planting, it can be transferred to a ventilated and cool place for maintenance.

Before planting, the roots of the cactus should be checked first, and it should be cleaned up in time after the rot is found, and after the pruning is completed, some plant ash can be applied to the wound for sterilization and disinfection, and then the cactus is placed in a ventilated and cool place to dry, and the wound can be sown after it is completely dry.

When sowing cacti, it is also necessary to choose the right soil and flower pots. Flower pots should be selected according to the size of the cactus, and the bottom of the pot should be guaranteed to have strong and balanced drainage. Well-drained slightly alkaline soil can be selected as the cultivation substrate, and compost, river sand, and garden soil can be mixed to make a cultivation substrate, so that cacti can grow healthily.

Before the cactus is potted, a small tile is laid at the bottom of the pot, and then the prepared soil is placed in the potting soil. After leveling the soil, bury the wounded side of the cactus in the soil about a quarter deep, and then fill the cactus with the right amount of soil around the roots to stabilize the cactus.

After the planting is completed, the cactus can be transferred to a ventilated and cool position for maintenance, and given appropriate astigmatism irradiation, maintain the temperature and humidity of the surrounding environment, and take root and germinate in about 20 to 30 days, and then normal maintenance can be carried out.

1. Reproduction methods.

Propagating cacti can be sown by sowing seeds, directly from seeds. However, this method is not commonly used because the process from sowing to germination to growth into a plant is extremely long, and the germination rate of sowing is not guaranteed. Therefore, the more common way to plant it is to take the mold is the cuttings method, which is not only easy to survive, but also takes a short time.

Second, the specific method.

2. Material: The stem should be moderately old and tender, and the stem that is too old or too tender is not conducive to rooting. Once selected, it is separated from the mother plant with a sterilized knife.

Then, leave it to dry in a well-ventilated place. It takes about five days to a week before it can be dried. At this point, the cortex can be observed to shrink inward, and there is a thin film.

3. Substrate: The substrate can be sandy, but it needs to be disinfected before use.

4. Cuttings: Insert the stems into the sterilized substrate to a depth of about three centimeters. After that, it should be watered, make sure it is moist, but not too wet to cause rot. It takes about twenty days to take root.

5. Transplantation: After taking root, you can transplant and plant. It is best to do it on a sunny day, prepare the pots and new substrate, and transplant the new plants that have taken root.

Cactus does not have high requirements for the environment, can be planted in spring, summer and autumn, first obtain cactus seeds from flowers, or directly buy excellent seeds, prepare soil with good ventilation and drainage and suitable size containers, after sowing cactus seeds, it is necessary to keep the soil slightly moist, so that the seeds can take root and germinate faster in the soil.

Cactus can be planted in spring, summer and autumn, but cactus is difficult to flower, if the cactus blooms generally in June and October, we can take out the cactus seeds from the cactus flowers, or you can go to the market to buy excellent cactus seeds, <>

If you want to plant cactus, you first need to prepare loose and well-drained fertile soil, we can use nutrient soil to plant cactus, or you can use humus, coarse sand, and small stones to mix in a ratio of 6:2:2 as a planting substrate.

When planting cacti, it is also necessary to choose a container of the right size to plant, usually it is best to choose a clay pot with drainage holes, clay pots and other containers to plant cactus, when putting the soil in, the drainage hole can be placed with tiles to help the soil drain and breathe, which is conducive to the growth of cactus roots.

Many people don't know how to plant cactus, in fact, the planting method of cactus is very simple, first sprinkle the prepared seeds on the soil, cover with a layer of fine soil and film, and then keep the soil slightly moist, the temperature can be controlled at about 15 20, which is conducive to the rooting and germination of cactus seeds.
