How to raise canna, canna culture methods and points for attention / watering should be flexible

Canna is a non-toxic and highly ornamental plant, so more and more people grow it, but many flower lovers find it difficult to blossom or even have weak leaves and yellow stems, so how can canna look better? Let's take a look at the correct canna culture methods and precautions.

How to raise canna

Many people can't raise canna well because they don't understand its growth habits, so before we figure out how to raise canna, we should be familiar with its preferences. Canna likes a warm and humid climate, the suitable temperature is 25-30 degrees, cold resistance is weak.

In addition, canna likes fertile and loose soil, has better requirements for light, likes sunny base fertilizer, can withstand a certain amount of water moisture, but does not like stagnant water, and is more afraid of strong winds, but likes a well-ventilated environment. The correct canna culture methods and precautions are based on these growth habits.

Culture methods and matters needing attention of Canna

1. What kind of soil is canna suitable for?

It does not have high requirements for soil, but if there are conditions, we can choose sandy soil with loose fertile and good drainage, such as rotten leaf soil, vegetable garden soil and rice chaff ash mixed in the proportion of 33%, 50% and 17%, which can make banana flowers bloom more brightly.

Note: no matter what kind of soil you choose, you must pay attention to sterilizing the soil. The method is to expose the soil to the sun. High temperature can kill most germs.

Second, the growth temperature of canna

Although the best temperature for its growth is 25-30 degrees, most of it cannot be maintained all the time, so usually we just need to keep the temperature above 15 degrees and below 30 degrees, and we should keep the temperature above 10 degrees in winter.

Note: if the temperature is below 10 degrees or higher than 40 degrees, the canna should be moved to a different environment, such as moving to the shade when the temperature is high and keeping warm when the temperature is low.

Third, lighting requirements

The normal growth of canna needs to keep enough light for more than 5 hours a day, so letting it bask in the sun for 5 hours a day can be beneficial to its growth, if the light is not enough, it will delay the flowering period and not bloom.

Note: the shade tolerance of canna is weak, do not plant it in a dark place, otherwise it will cause the plant to wither and die.

IV. Fertilization

In the cultivation methods and matters needing attention of canna, basal fertilizer is applied at the bottom of the pot before planting, fertilized 2-3 times a month when the growth is exuberant, and topdressing can be applied before flowering to promote flowering.

Note: fertilizer should pay attention to balanced nutrition, if too much nitrogen fertilizer will make the leaves thick, too much ferrous sulfate will be scorched at the edge of the leaves, should be avoided as far as possible.

Fifth, watering

From the beginning of the seedlings, canna can not thrive without watering. Watering is neither too frequent nor too lazy. Watering time can be chosen according to different growth stages, and the judgment method is that the soil is moist and does not accumulate water.

Note: watering is a key factor in raising canna, and it is taboo to soak the roots of the plant in water each time. If this happens, check whether the soil is well drained and whether there is too much watering.

How to raise canna? Cultivation methods and matters needing attention of Banana in pots

Canna, also known as red banana, small flower canna, small canna, etc., is a perennial herb of the genus Canna of the Canna family. Canna is a common flowering plant in subtropics and tropics, with large and colorful flowers and rich colors, so it is often potted indoors. So, how to raise canna? Now the cultivation methods and matters needing attention of banana pot cultivation are introduced as follows.

I. cultivation methods of banana in pots

1. The appropriate basin is deep and the soil is loose: canna is a root plant, and the basin should be deeper and larger, with a tile basin with a diameter of 3040 cm. It has strong adaptability and does not choose soil, so it grows best in fertile, loose and well-drained sandy loam. Rotten leaf soil and vegetable garden soil can be mixed with a small amount of sand as culture soil. When planting, it is appropriate to plant deeply and cover 68 cm of soil. Put a layer of broken hard plastic foam at the bottom of the basin to facilitate ventilation and drainage. Change the basin and soil every spring.

two。 Moderate inflow and frequent fertilization: during the growing period of canna, the basin soil should be dry and wet, and waterlogging should be discharged at any time in the rainy season. The basin soil should be drier during the dormant period. Like fertilizer, in addition to adding some bone meal and nitrogen, phosphorus and potassium compound fertilizer to the culture soil during the growing period, apply nitrogen, phosphorus and potassium compound fertilizer once in the growing period, and do not apply it at flowering, continue to apply nitrogen fertilizer after flowering, avoid single application of nitrogen fertilizer, otherwise there are more leaves and less flowers. No fertilizer is applied during dormancy.

3. Like light, like warm and afraid of cold: beauty steaming is a tropical negative flower, which should be placed on a sunny courtyard, roof garden or west balcony with good ventilation and sunshine, so that not only the roots are big and tillers, but also the flowers are many and gorgeous. if placed in shade, the plant is tall, the color is light, or even no flowers. Fearing frost and snow freezing, Frosts Descent cut off all the scorched yellow leaves and buckled an empty flowerpot on the pot. the south of the Yangtze River can survive the winter safely outside, and people need rooms to survive the winter to the north of the Yangtze River. Prune the flower stem in time. For potted canna, the flower stem should be cut off from the lower part of the stem in time after flower fade, and fertilized to promote it to grow new stem from the stem root, and it can blossom again after one and a half months, so that it can blossom for 34 crops from late May to October, and always insist on beautiful flowers and leaves.

4. Ramet reproduction is easy to survive: in spring, combined with changing the basin and soil, the root is poured out and cut into several pieces with a sharp knife, each with at least 23 buds. The incision is smeared with sulfur powder or charcoal and can be carried in the basin respectively. It can also be bred after anthesis and sowed and propagated in the next spring.

II. Matters needing attention in pot culture of canna

1. Ensure light: during the growing period, canna requires sufficient light to ensure that it receives at least 5 hours of direct sunlight every day.

two。 Pay attention to controlling the amount of fertilizer application: potted canna sometimes appear scorched and yellowed at the edge of the leaves, mainly due to excessive application of ferrous sulfate. If the fertilizer is too thick in the heat of summer, it will burn the roots of canna, causing it to "burn to death". Stop fertilizing during the flowering and winter periods of canna.

3. Summer watering must not be too cold: in a hot summer, if the water temperature is too cold, the water will also cause scorch on the edge of the leaf.

4. Pruning the flowers in time: when the flowers at the end of the stem fall behind, the stem branches should be cut off from the base at any time in order to sprout new buds and grow flower branches to bloom one after another.

[editor's conclusion] Canna likes a warm and sunny environment and is not hardy, so it needs special attention in the process of breeding. Above for you to introduce the banana pot culture methods and matters needing attention, I hope to help you!

Culture methods and matters needing attention of canna

Culture methods of canna

Light

Canna growth is suitable for all-day sunshine, the environment is too dark, lack of light, the flowering period will be delayed. If you put it in a cool place during flowering, you can prolong the flowering period.

Temperature

The suitable growth temperature of canna is 15 ℃-30 ℃. During flowering, placing canna in a place with low temperature and no light can prolong the flowering period, and the ambient temperature should not be lower than 10 ℃.

When the temperature is above 40 ℃, the canna can be moved to a cool and ventilated place. Before and after Frosts Descent, the potted canna can be moved to a temperature of 5-10 ℃ to survive the winter safely.

Watering

During the growing period, canna needs to spray water on its leaves 1-2 times a day to maintain humidity.

Because canna is very fond of fertilizer and moisture resistance, so the basin should be watered thoroughly, and the watering times should be grasped according to the actual situation.

Fertilizer application

Apply sufficient basal fertilizer before planting, in addition, topdressing 3mi 4 times a month during the peak growth period.

Soil

Canna does not have high requirements for soil, but it grows best in loose, fertile and well-drained sandy soil, even in fertile clayey soil.

Matters needing attention in Canna Culture

Ensure the light

Canna requires plenty of light during its growing period, ensuring that it receives at least five hours of direct sunlight every day.

Pay attention to controlling the amount of fertilizer application

Potted canna sometimes shows scorched and yellowed leaves, mainly due to excessive application of ferrous sulfate.

If the fertilizer is too thick in the heat of summer, it will burn the roots of canna, causing it to "burn to death".

Stop fertilizing during the flowering and winter periods of canna.

Never get too cold when watering in summer.

In a hot summer, if the water is too cold, it will also cause scorching at the edge of the leaves.

Timely pruning after falling behind

When the flower at the end of the stem lags behind, the stem branch should be cut off from the base at any time in order to sprout new buds and grow flower branches to blossom one after another.
