How to Propagate Morning Glories: Methods and Precautions Explained

Morning glories have strong adaptability, prefer warm and sunny environments, and are not difficult to cultivate, making them very popular. Morning glories are very famous ornamental flowers. When cultivating morning glories artificially, they can be propagated by sowing seeds. I will now introduce the seed propagation method for morning glories in detail, and interested friends can learn about it together.

Morning glory

1. Seedling raising: The germination temperature for morning glory seeds is 20-30°C. Generally, sowing is done in late April to early May (in the south it can be earlier). Sow by variety in rows in a fine sandy soil seedbed. When humidity is moderate, germination occurs in about 10 days. After about another 10 days, the cotyledons fully open. When the true leaves have just sprouted, they should be transplanted into small pots. Too early and the seedlings will be weak; too late and the roots will be damaged, neither of which is good for subsequent development. Small pots should be marked with the variety name.

2. Planting out: After the seedlings in the small pots grow two or three true leaves, the root system has developed well and they can be planted out in medium pots with basal fertilizer added in advance. As Mr. Mei said, morning glories are not afraid of heavy fertilizer; horse hooves, cooked hemp residue, etc. can be used as basal fertilizer. The root system development of morning glories needs temperature. According to Japanese researchers, black pots absorb heat better than red pots. The pots should be turned frequently to ensure even sunlight exposure and complete root system development.

3. Pinching: After three or four true leaves have grown on the morning glory, vines begin to grow from the center, and at this time they should be removed. After the first pinching, side vines grow from the leaf axils. After the side vines produce three or four leaves, pinch again, and at the same time combine with shaping. After each pinching, topdressing should be applied, using fertilizer similar to that used for chrysanthemums. Be careful not to let fertilizer water and mud stain the leaves (including cotyledons), so as to prevent leaf drop. After the vines grow, they enter the flowering period (generally one month after planting out). Ideally, the first leaf of the vine produces axillary buds again, and the leaf axils of the second and third leaves produce flower buds.

4. Seed saving: Good varieties must have their seeds saved. After they mature in autumn, collect the seeds, label them by category, and store them. If variations appear, they should be preserved with even greater care. For hybridization of morning glories, after selecting the female and male parents, cut off the upper end of the flower bud at dusk the day before flowering, then remove the stamens and wrap with a wax paper bag. The next morning, remove the wax paper bag, use the stamens of the male parent for artificial pollination, then wrap with the wax paper bag again. After one or two weeks, the wax paper bag can be removed, but the pollinated seed pods must be marked and recorded. The following year, all the hybrid seeds should be planted well, and after flowering, the results can be observed, from which the effects of various genetic factors can be studied.

5. The method for cultivating morning glories in winter is: in autumn, promptly select and collect seeds of morning glories with excellent flower colors. After the Beginning of Winter, sow the seeds in potting soil. The potting soil should have three or four horse hooves buried as basal fertilizer or be mixed evenly with a small amount of hemp residue powder as basal fertilizer. After sowing, water the potting soil thoroughly with warm water at about 25°C, cover with a glass plate or put on a plastic bag, and place on a warm, sunny windowsill. After the seedlings emerge, promptly remove the covering. After thinning and hardening the seedlings, finally select and keep 2-3 strong seedlings, insert support stakes, and guide the vines to climb, allowing them to grow and bloom naturally. For routine management, just pay attention to timely watering with water close to room temperature, always maintain sufficient light, and be careful to prevent the leaves from frost damage. The method for dwarf cultivation is: when the cotyledons or the first to second true leaves of the morning glory seedling have unfolded, promptly remove the terminal bud, forcing the plant to become dwarfed and upright. In this way, the leaf axils of the cotyledons and true leaves can produce buds and bloom. Because morning glories have the characteristic of being able to accept photoperiod induction at the cotyledon stage, the buds and flowers can appear with large corollas and beautiful flower colors. If sowing is staggered over time in multiple pots, and each pot is sown with morning glory seeds of multiple flower colors, then when they bloom, they will come one after another, presenting something new each day, extremely fresh and unique, adding interest to the indoor space in winter.

Petunia Cultivation Methods and Precautions

Petunias have bright flower colors and a particularly long flowering period. They symbolize family peace and harmony and are ornamental plants that people most like to grow at home. However, growing petunias well is not a simple matter. In addition to mastering their cultivation methods, you also need to know what to pay attention to during cultivation. Otherwise, they often show undesirable symptoms such as failure to bloom, yellow leaves, and death. The following is a specific introduction to their cultivation methods and precautions. Those of you who like this plant can focus on understanding it.

When growing petunias normally, prepare loose, fertile, well-draining soil, and place them in an environment with ample light and good ventilation. After planting petunias, water them thoroughly, and apply fertilizer once every half month. After petunias grow three or four leaves, vines begin to grow from the center, and at this time they should be promptly removed. Only in this way can flower branches be promoted and more beautiful flowers be produced.

1. Pay attention to temperature

During the process of growing petunias, be sure to pay attention to regulating the environmental temperature, because this plant is not tolerant of frost or high temperatures. It grows fastest in an environment of 13 to 18 degrees. In an environment below ten degrees, it will stop growing, and below four degrees, it will die due to excessively low temperature. Therefore, in winter, petunias must be placed in a warm environment. In summer, morning glories should not be placed in a high-temperature environment above 35 degrees. If the weather is hot and the temperature is too high, promptly spray water on the leaves to cool them down.

2. Pay attention to fertilizing

Fertilizing petunias is also a particularly important point to note. At different growth stages, their fertilizer requirements are not the same. During the seedling stage, thin fertilizer should be applied frequently, and a compound fertilizer with high nitrogen and potassium content should be chosen. After they enter the flowering period, the supply of phosphorus fertilizer should be increased. Only in this way can their flower colors be brilliant. In addition, when planting petunias normally, sufficient basal fertilizer should also be applied.

3. Pay attention to pests and diseases

When growing petunias, also pay attention to the prevention and control of pests and diseases. Normally let them receive moderate sunlight, and pay attention to environmental ventilation; otherwise, they may develop net rot or leaf spot disease. After these diseases occur, chlorothalonil or carbendazim can be sprayed, and the diseased branches and leaves should be promptly removed. In addition, during the growth process, petunias are also prone to pests such as aphids and leaf rollers. At this time, a pyrethrin solution needs to be sprayed promptly to eliminate the pests.

How to Grow Morning Glories: Cultivation Methods and Precautions for Morning Glories

Morning glory is also called morning glory, belonging to the Solanaceae family. Its flower colors can be described as colorful, and quite a few people like it. How do you grow morning glories? Today I will tell everyone about the cultivation methods and precautions for morning glories.

Cultivation methods for morning glories:

1. Soil: Morning glories are afraid of too much water, which can cause root rot and other problems, so potted morning glories should use loose, fertile, and well-draining sandy loam soil.

2. Watering: Normally, morning glories should be watered in moderation, preventing both excessive dryness and excessive moisture. If too dry, the plant tends to wilt; if too wet, the roots tend to rot. In summer, when the weather is hot and evaporation is greatest, watering should be replenished promptly to keep the potting soil moist but not waterlogged. During the rainy season, drainage should be timely to prevent waterlogging.

3. Light: Morning glories are long-day plants and require relatively strong light conditions for photosynthesis to proceed smoothly. Therefore, whether potted or planted in the ground, they need to be given sufficient light. With ample sunlight, they grow robustly with lush leaves and abundant flowers; if light is insufficient, the branches and leaves tend to grow leggy, with few flowers or poor flower quality. If they can be given more than 12 hours of light per day, and the night temperature is above 10°C, they can bloom in all four seasons.

4. Temperature: Morning glories are not tolerant of frost. The suitable growth temperature is 13-18°C. In winter, the temperature should be 4-10°C. If below 4°C, plant growth stops. In summer, they can tolerate high temperatures above 35°C.

5. Fertilizing: Morning glories have a long flowering period and need continuous nutrient replenishment to keep blooming. In the early stage of seedling growth, thin fertilizer should be applied frequently. Choose fertilizer with high nitrogen and potassium content and appropriately low phosphorus. For nitrogen fertilizer, urea can be chosen. For compound fertilizer, choose one with an N-P-K ratio of 15-15-15 or one with high nitrogen and potassium. Control the concentration at 0.1%-0.2%. For water-soluble fertilizers, generally choose 20-10-20 and 14-0-14, with a concentration of 50×10-6 to 100×10-6. For producing potted flowers in winter, apply compound fertilizer frequently in March to April, and according to growth conditions, appropriately apply additional nitrogen fertilizer.

6. Pests: The main diseases of morning glories are damping-off at the seedling stage and stem rot during the growing period. The main pests include diamondback moths, aphids, leaf rollers, and so on. Damping-off can be controlled with chlorothalonil or thiophanate-methyl at 800-1000 times dilution. When aphids appear, fenvalerate generally should not be sprayed, as it easily causes phytotoxicity and affects growth.

7. Pruning: When morning glory seedlings grow to about 10 cm tall, pinch them to encourage side branches to sprout, resulting in more flowers. After each flowering, if seeds are not needed, promptly cut off the spent flowers and shorten the branches, so that side branches can continue to sprout and bloom continuously.

Precautions for cultivating morning glories:

1. Do not let fertilizer water and mud stain the leaves (including cotyledons), so as to prevent leaf drop. After the vines grow, they enter the flowering period (generally one month after planting out). Ideally, the first leaf of the vine produces axillary buds again, and the leaf axils of the second and third leaves produce flower buds. After the flower buds take shape, the stipules of the flower buds can be removed to facilitate bud development. To ensure sufficient nutrients are supplied to the flower buds so they produce large and brilliant flowers, some flower buds can also be removed to cultivate single flowers, just like cultivating variety chrysanthemums. After flowering, remove the spent flowers and do not let them set seed, so as to avoid adverse effects.

2. Choosing pots: Morning glories are suitable for planting in earthenware pots with good permeability and an inner diameter of 20-30 cm, with two or three plants per pot. If using purple clay pots, plastic pots, or porcelain pots with poorer permeability, place a layer of broken charcoal pieces or broken hard plastic foam pieces at the bottom of the pot to enhance air permeability and drainage and prevent root rot. Plastic hanging pots can also be used, with 1 plant per pot, hung on a balcony or window.

For soil selection, loose, fertile, slightly acidic sandy loam is best for planting. Culture soil can be prepared with leaf mold, vegetable garden topsoil, and sand or perlite at a ratio of 5:4:1. A pH value of 5.8-6.2 is best. If the pH value exceeds 6.6, it will inhibit the roots' absorption of iron, causing leaf yellowing. Heavy clay soil and saline-alkali soil should be avoided.

3. More light: Morning glories like light, like warmth, and are not cold-tolerant. The most suitable growth temperature is 15-25°C. Except that proper shading is needed at noon when the high temperature in midsummer is above 34°C, sunlight should be abundant in all other seasons, and the more sufficient the sunshine, the more luxuriant the growth and the more flowers. They should be placed in a sunny courtyard, roof garden, south- or west-facing balcony, or windowsill.

4. Frequent pruning: During the growing period, proper pruning and branch training not only controls plant shape but also promotes more flowering. In cool climates, they can bloom continuously all year round.
