The corn poppy can monitor sulfur dioxide. Keep this care guide handy.
The corn poppy (Papaver rhoeas) is also known as "rival of the peony," "amusing beauty," "beautiful spring flower," "brocade quilt flower," and "butterflies filling the garden in spring." It is a flower variety with very high ornamental value, loved by people from ancient times to the present. So how do you care for the corn poppy? Let's learn about the corn poppy care guide together with the Huinong website editors.
1. Brief introduction to the corn poppy
Before the flower opens, the bud is egg-shaped, wrapped in two sepals, and the sepals are green with white edges. The flower stalk is slender and upright, drooping slightly, and the flower has 4 petals with unusual colors. Du Fu praised it in a poem: "Of all the grasses competing in spring splendor, the beautiful spring flower should be the finest."
2. Monitoring function
The corn poppy mainly detects hydrogen sulfide. Once the air contains hydrogen sulfide gas, the leaves of the corn poppy will scorch and develop spots, and even the flower buds will show a reaction.
3. Care guide
(1) Light
The corn poppy likes sun and needs sufficient light, so when kept indoors, be sure to guarantee good light. However, shade it during the early stages after transplanting; once it has established, gradually expose it to sunlight and then gradually extend the light duration.
(2) Temperature
The corn poppy fears intense heat but has a certain cold tolerance and likes a warm environment. The temperature should be controlled at 15-28°C. In winter it enters dormancy, and at this time it can tolerate slightly low temperatures.
(3) Watering
Water potted corn poppies once every 3-5 days. Usually there is no need to water too much. During the growing period, that is, around the Beginning of Spring, you can appropriately increase the frequency of watering to maintain soil moisture, but absolutely avoid waterlogging. Winter is the dormant period; as long as the soil is not excessively dry, it is fine, and watering must not be frequent.
(4) Fertilizing
The corn poppy suits fertile soil. During the growing period, apply fertilizer once every 2-3 weeks. Use decomposed urine diluted with 5 times water as the fertilizer, and give one more topdressing before flowering.
(5) Propagation
Generally speaking, the corn poppy is suitable for propagation by sowing, and it can be sown in both spring and autumn.
(6) Pinching
When the corn poppy seedlings grow 6-7 leaves, they should be pinched back. This is to encourage the seedlings to branch. If you are not saving seeds, promptly cut off the spent flowers that have not fully dropped during the flowering period to ensure the plant's nutrients, which can make later flowers more vivid and also extend the flower
(7) Placement and display
The corn poppy has vivid flowers and graceful posture. Potted corn poppies grown at home are suitable for placement in the living room, balcony, windowsill, and other places with ample light and good ventilation. They can also be made into vase arrangements and placed in the living room, study, or dining room.
The above is the corn poppy care guide compiled by the Huinong website editors. Have you all learned it? The corn poppy is relatively simple to grow, but caring for it is not so easy. So friends who want to grow corn poppies well must patiently learn the above care techniques.
Care guide for canna, which has the function of monitoring sulfur dioxide
Canna is native to tropical and subtropical America and is also known as red brilliant canna, orchid canna, tiger-head canna, and blood-breaking red. It has high ornamental value and also has the function of monitoring sulfur dioxide. Now let's learn together about the canna care guide.
1. Monitoring function
Canna can remove and monitor the harm caused by harmful gases such as sulfur dioxide and chlorine, and issue a warning. When its leaves are found to lose green and turn white, and the flowers and fruits drop, be especially careful of chlorine pollution.
2. Care guide
(1) Light
During the growing period, it requires sufficient light and must receive at least 5h of direct sunlight every day. If the environment is too dark and light is insufficient, the flowering period will be delayed.
(2) Temperature
Canna likes higher temperatures. The suitable growing temperature is 15-28°C. If the temperature is below 10°C, it is unfavorable for its growth.
(3) Watering
Canna can tolerate short periods of waterlogging, but it fears too much water; if there is too much water, it easily causes rhizome rot. When canna has just been planted, water it frequently, once a day, but the amount of water should not be too much. During drought, spray water on the branches and leaves more often to increase humidity.
(4) Fertilizing
Before planting, apply sufficient base fertilizer into the soil. During the growing period, the plant should be topdressed frequently. After the plant grows 3-4 leaves, apply liquid fertilizer once every 10 days until flowering.
(5) Propagation
Canna can be propagated by sowing or by division.
(6) Pruning
After flowering, cut off the spent flowers as early as possible to reduce nutrient consumption and encourage the plant to continue producing new flower branches. In northern regions, after Frost's Descent, if canna suffers frost, all the aboveground parts will turn yellow and withered. At this time, cut off the withered aboveground parts, dig out the rhizomes, dry them slightly, then store them indoors buried in sandy soil, and replant them the following spring.
(7) Placement and display
Canna can be planted directly in the courtyard for appreciation, or grown in wooden tubs or large flower pots and placed in the living room, balcony, rooftop, corridor, and other places.
The above is the canna care guide compiled by the Huinong website editors. Have you all learned it?
Care guide for asparagus fern, which has the effect of "sterilizing and inhibiting bacteria"
Asparagus fern (Asparagus setaceus) is also called cloud-slice bamboo. It has elegant charm and extremely high ornamental value, and at night it has the effect of sterilizing and inhibiting bacteria. Asparagus fern is a perennial evergreen herb, with flowers close to white, black seeds, and spherical berries. Many flower lovers enjoy growing asparagus fern. Now the Huinong website editors will tell you about the asparagus fern care guide.
1. Environmental benefits
At night, asparagus fern can absorb harmful gases such as phosphorus dioxide and sulfur dioxide. The gas released by the plant has the function of sterilizing and inhibiting bacteria.
2. Care guide
(1) Light
Asparagus fern must not be put out in the blazing sun. In hot seasons, place it in a cool, ventilated spot. At the same time, during the flowering period, asparagus fern fears both wind and rain, so pay attention to good ventilation. In good weather, it can appropriately be placed outdoors to receive sunlight.
(2) Temperature
In winter, keep the room temperature at around 5°C and place it in a sunny area, and it can overwinter safely.
(3) Watering
Usually water so that dry and wet alternate: do not water when not dry, and when watering, water thoroughly. Do not give "half watering," and even more do not keep it too wet or waterlogged for a long time, otherwise the fleshy root system will grow poorly and root rot will result. In hot, dry seasons, besides keeping the potting soil moist, also spray water on the branches, leaves, and surroundings.
(4) Fertilizing
During the spring and autumn growing periods, apply fertilizer once every 10 days, mainly nitrogen and potassium fertilizers, and add phosphorus fertilizer before the flowering period. Stop fertilizing during high summer temperatures to avoid damaging the roots.
(5) Soil
It likes soil rich in humus, loose, and well drained. For the potting soil, use a culture soil mixed from 4 parts garden soil, 4 parts leaf mold, and 2 parts yellow sand.
(6) Propagation
For soil culture, asparagus fern commonly uses sowing and division, and it can also be hydroponically grown. Division propagation is often done together with repotting in spring: dig out the whole plant and divide it into several clumps, potting them separately. However, seedlings obtained by division often have irregular plant shape and a low survival rate, so it is used less often.
(7) Placement and display
Asparagus fern is mainly grown in pots for its foliage. Fresh and elegant, it adds even more literary charm when placed in a study. Slightly larger potted plants can be placed on a windowsill. For large potted plants, add a support so the leaves are evenly distributed, and they can be displayed in a corner.
The above is the asparagus fern environmental benefits and care guide compiled by the Huinong website editors. Have you all learned it? Asparagus fern is fresh and elegant and very suitable for growing at home.
