How to grow Cleome? Detailed Guide to Cultivation Methods and Precautions
Cleome Growth Habits
Cleome has strong adaptability, prefers high temperatures, tolerates summer heat fairly well, and dislikes cold. It likes sunny locations but can also grow well in partial shade. It is not demanding about soil; in fertile ground with ample water and nutrients, plants grow tall, and it also grows well in soil of average fertility, but grows poorly in sandy loam, heavy clay soil, or alkaline soil. It likes moist soil and is fairly drought-tolerant, but dislikes waterlogging.
Cleome Propagation Methods
1. Sowing:
For seed propagation of Cleome, sow the seeds in an open-field seedbed in mid-April, and seedlings emerge uniformly. The seedlings grow slowly, so thinning must be done promptly after sowing; transplant when they have 2-3 true leaves, and set out or pot up in June. Apply fertilizer once every half month during the growing period; excessive fertilization can easily cause leggy growth, affecting plant form and flowering. Generally, spring-sown plants flower in autumn, while autumn-sown plants flower indoors in winter and spring.
2. Cuttings:
For Cleome cuttings, use materials such as nutrient soil, river sand, or peat soil. The optimal temperature for cutting rooting is 18-25°C. Below 18°C, the relative air humidity must be maintained at 75-85%. Humidity can be increased by misting the cuttings, and 50-80% of sunlight must be shaded out. After roots develop, gradually remove the shade netting.
Cleome Cultivation Techniques
Soil
No special soil is required; sandy soil rich in humus with good drainage is best. Cleome has a fairly developed root system, so use a slightly deeper and larger pot, preferably with a pot diameter of 20 cm to 30 cm. Except for poor growth in alkaline soil, it can grow in sandy soil and clay soil, and grows best in slightly acidic sandy loam. You can use equal parts leaf mold and garden soil mixed as the growing medium. The soil should be loose and well-draining.
Potting
Potting or transplanting: When potting young seedlings, first place a 2-2 cm thick layer of coarse-grained substrate or expanded clay pellets at the bottom of the pot as a drainage layer, sprinkle a layer of fully decomposed organic fertilizer on top as base fertilizer, about 1-2 cm thick, then cover with another layer of substrate about 1-2 cm thick, and then place the plant in, so as to separate the fertilizer from the roots and avoid burning the roots.
For the potting substrate, you can choose one of the following. Garden soil: cinder = 3:1; or garden soil: medium-coarse river sand: sawdust (mushroom residue) = 4:1:2; or one of paddy soil, pond mud, or leaf mold. Or peat + perlite + expanded clay pellets = 2 parts + 2 parts + 1 part; garden soil + cinder = 3 parts + 1 part; peat + cinder + expanded clay pellets = 2 parts + 2 parts + 1 part; sawdust + vermiculite + medium-coarse river sand = 2 parts + 2 parts + 1 part. After potting, water thoroughly once and place in a slightly shaded environment for one week of care.
Fertilizing
When transplanting young seedlings, first dig the planting hole, sprinkle a layer of organic fertilizer at the bottom of the hole as base fertilizer, about 4-6 cm thick, then cover with a layer of soil and place the seedling in, so as to separate the fertilizer from the roots and avoid burning the roots. After placing the seedling, backfill the soil to cover the roots, firm the soil with your foot, and water thoroughly once. Apply a light fertilizer once at initial planting. Control fertilization during the mid-growth stage to keep the plant form moderate and attractive. Like other herbaceous flowers, it has relatively high fertilizer and water requirements, but the fertilization (and watering) principle of “apply light fertilizer frequently, use small amounts more often, and provide complete nutrition” should be followed, and after fertilizing, keep the leaves and flowers dry at night. For container-grown plants, apply 2-3 times of dilute compound liquid fertilizer during the bud stage, and they can bloom around the Spring Festival.
Pinching
Before flowering, generally pinch twice to encourage more flowering branches: one to two weeks after potting, or when the seedling is 6-10 cm tall and has more than six leaves, remove the growing tip and keep the lower 3-4 leaves to encourage branching. Three to five weeks after the first pinching, or when the side branches grow to 6-8 cm long, perform the second pinching, that is, remove the growing tips of the side branches and keep the lower 4 leaves on the side branches. After two pinchings, the plant form will be more ideal and the number of flowers will be greater. When planting in flower beds, promptly remove spent flowers so they do not set seed, thereby extending the flowering period.
Watering
It can tolerate drought, but grows better with higher air humidity. In midsummer, water daily and water thoroughly. It likes higher air humidity; if air humidity is too low, individual flowers fade faster. It also fears rain, and the leaves need to stay dry at night. The optimal relative air humidity is 65-75%.
Light
It likes sunlight and warmth, tolerates heat, slightly tolerates partial shade, and does not tolerate cold. Summer is the growing period, and plants die when frost occurs. The suitable temperature for growth is 20-32°C.
Seed Saving
Cleome sets seed quite easily. When the capsules begin to turn from green to yellow, they can be harvested. After harvesting, air-dry the seeds and store them in a cool place for use the following year. When propagating by seed, the fruits are slender and mature successively from late summer to early autumn, so they can be collected in stages. The seeds are very small; after harvesting and drying in the shade, store them in bags indoors in a cool place or in the refrigerator. Early-maturing seeds can be sown immediately after harvest, and will flower in late autumn to early winter. Generally, seeds are stored over winter and sown in early spring of the following year to flower in summer, or sown in late spring to flower in summer and autumn. Sow in an open-field seedbed and keep moist after covering with soil. When the seeds germinate, the temperature must be above 20°C; in early spring, sowing must be kept warm in a plastic tunnel for uniform germination. If the temperature is suitable, germination occurs about 1 week after sowing. The seeds have the ability to self-sow and reproduce.
Cleome Pest and Disease Control
Leaf spot and rust are common problems. For leaf spot, spray with 50% thiophanate wettable powder at 500 times dilution; for rust, spray with 50% carboxin wettable powder at 3000 times dilution. Cleome is prone to Lepidoptera pests at the seedling stage. Foliar spraying with the insecticide abamectin at 4000 times dilution can be used.
Main Value of Cleome
Landscaping
Cleome's petals are light and graceful, and when in full bloom they resemble butterflies dancing, which is quite interesting. It can be used in summer and autumn to arrange flower beds and flower borders, and can also be dwarf-cultivated as a potted ornamental. In landscaping applications, because of its ability to tolerate partial shade, it can be planted under trees or on the shady side of buildings for viewing.
Economic
Cleome opens in the evening and withers the next day, so it is also called the flower of summer nights; its brief life gives a sense of illusory impermanence. This Cleome is native to the tropical regions of South America and is an excellent pollution-resistant flower, with strong resistance to sulfur dioxide and chlorine gas; it can beautify the environment and is an excellent pollution-resistant flower that can also grow well in heavily polluted factories and mines. It is also an excellent nectar plant and can be used to extract high-quality essential oil.
Decorative
Cleome's flower stalks are long and sturdy, and the raceme forms an abundant ball of flowers, with red and white setting each other off and a pleasing balance of depth and lightness. In particular, its long-clawed petals and long stamens extending beyond the corolla resemble spiders, and also dragon whiskers, which is quite interesting. When Cleome opens, the petals slowly spread, and the long claws go from curved to popping out from the flower, a process like a film sequence slowed down. When planted in the ground, it can be placed beside courtyard walls or under trees. When potted, it can be displayed on a windowsill or desk, and the plant form should be controlled so it does not grow too tall.
Medicinal
Whole plant: pungent, astringent, neutral. Slightly toxic. Dispels wind and disperses cold, kills parasites and relieves itching. Fruit: folk trial use for liver cancer.
How to grow Cleome, Cleome cultivation methods and precautions / ample sunlight
Cleome is a plant native to the tropical regions of the Americas and was later introduced to China. Today, people in many parts of China grow it. However, there are many points to note if you want to grow it well. How do you grow Cleome? What are the cultivation methods and precautions for Cleome? Below, the editor will walk you through it.
1. How to grow Cleome: understand its habits
If you want to know how to grow Cleome, you first need to understand its growth habits. This plant is relatively light-loving, so during cultivation we should keep it in sufficient light so that it can grow better. In addition, daily watering and fertilizing are also points to note. The details are below; let's take a look.
2. Cleome cultivation methods and precautions
1. Soil: slightly acidic sandy loam
When growing Cleome, we first need to choose the soil, which is the foundational step and is very important. Generally, we can choose loose, fertile, slightly acidic sandy loam. This kind of soil has good drainage, allowing it to grow better, and is less prone to water accumulation.
2. Fertilizing: apply light fertilizer frequently
Fertilizer is one of the main nutrients in Cleome's growth process. When fertilizing, we should maintain the principle of “apply light fertilizer frequently, use small amounts more often, and provide complete nutrition,” and after fertilizing, keep the leaves and flowers dry. One point to note when fertilizing is that the fertilizer must first be diluted with water so it can be absorbed better; if the fertilizer is too concentrated, it can easily burn the plant.
3. Temperature: 20-32°C
During Cleome's growth process, the ambient temperature is very important. Only when it grows at a suitable temperature can it grow better. The suitable ambient temperature for Cleome is between 20-32°C. This plant is relatively intolerant of cold, so during cultivation we should not let the ambient temperature be too low, otherwise it will affect its growth.
4. Moisture: maintain air humidity
Cleome is fairly drought-tolerant, but during growth, having some humidity in the surrounding environment is beneficial for its growth. Its most suitable air humidity is around 65-75%. If the air humidity is too low, individual flowers will fade faster. In midsummer, we basically need to water it every day to maintain some moisture in the potting soil.
5. Light: pay attention to shading in summer
Cleome is a relatively light-loving plant, so when growing it normally, we can place it in direct sunlight so it can photosynthesize better and grow better. However, when the summer sun is too strong, it is still best to pay attention to shading to avoid scorching the plant.
6. Pests and diseases: prevent and control promptly without delay
During Cleome's growth process, if our care is not careful enough, pests and diseases can easily appear. Such problems are extremely harmful to the plant, not only affecting its ornamental value but in severe cases also causing the plant to die, so our prevention and control must be timely. For specific treatment methods, you can refer to the article on Cleome pest and disease control; the editor will not introduce them in too much detail here.
How to plant Cleome: Cleome planting methods and precautions
Many people do not know about Cleome, but those hearing the name for the first time can imagine that it is a particularly beautiful and striking flower. In fact, Cleome is indeed beautiful and eye-catching, and it can also attract bees and butterflies; you can always see butterflies and bees around Cleome, which makes people yearn for it. So do you know how to plant Cleome?
How to plant Cleome
1. First, prepare the soil for sowing. This plant does not need overly special soil, but it is best to prepare some sandy soil containing humus with good drainage. Because except for poor development in alkaline soil, this plant can grow healthily in either sandy soil or clay soil, and grows most healthily in slightly acidic sandy soil. If you want to mix the soil yourself, you can mix leaf mold and garden soil in equal parts evenly as the soil for sowing and cultivation.
2. After the soil is prepared, it should be disinfected. This can prevent pests and diseases from attacking the seeds or seedlings. The best disinfection method is to heat the soil in a pan, killing pests and diseases with high temperature.
3. Next, to improve the success rate of seed germination, we can pre-germinate the seeds first. Soak the seeds in water at about 25 to 30 degrees for 3 to 10 hours, until the seeds swell from absorbing enough water, then take them out.
4. Some seeds are difficult to pick up by hand, so we can prepare toothpicks, wet one end with water, and use it to pick up the seeds and place them on the prepared cultivation soil layer. They should be separated one by one, then covered with a 1 cm thick layer of soil. Then place the sown pot in water, with the water depth reaching about one-half or two-thirds of the pot's height, allowing the water to slowly seep up.
5. For larger seeds that can be picked up by hand, they can be placed directly on the soil layer, with a spacing of 3x3 cm between seeds. After sowing, cover with another layer of soil, about 2 to 3 times the volume of the seeds in thickness. After sowing, moisten the soil layer with water, and then water once the soil in the pot looks slightly dry.

When to sow Cleome
Cleome's growth pattern is similar to ordinary crops: planted in spring and harvested in autumn. So sowing is of course chosen in spring, when all things revive.
When the seeds germinate, the temperature must be above 20°C; in early spring, sowing must be kept warm in a plastic tunnel for uniform germination. If the temperature is suitable, germination occurs about 1 week after sowing. Gardeners in the north can appropriately delay the sowing time, because spring in the north always arrives quite late.
In summary, I believe everyone has gained some understanding of Cleome cultivation methods. In fact, Cleome not only has extremely high ornamental value, it can also be eaten! Moreover, it tastes especially good, contains rich nutrients, and also has good effects on some diseases!
