Commelina erecta L. prefers well-draining, fertile soil that is rich in organic matter. The soil pH should be neutral to slightly acidic, with a range of 6.0 to 7.5. The plant is tolerant of a range of soil types, but it does not do well in heavy clay soils that retain too much water. It is important to avoid overwatering and ensure that the soil is allowed to dry out slightly between waterings.
Cultivation methods
The plant Commelina erecta L. can be grown both indoors and outdoors. If you are growing it indoors, then make sure your plant has access to bright but indirect sunlight. If it is grown outdoors, then it should have access to partial shade. When planting, ensure that the soil is well-draining and rich in organic matter. The pH of the soil should be between 5.5 and 7.5. Avoid planting in waterlogged soils.
Watering needs
The plant prefers consistent soil moisture instead of drying out and then becoming flooded with water. The frequency of watering will depend on the climate and weather in your location. In areas with high humidity, it won't need to be watered as often, while in areas with low humidity, it may require more frequent watering. When watering, make sure to provide enough water so that the soil is moist but not waterlogged.
Fertilization
To provide necessary nutrients for the growth of the plant, fertilize it every three weeks using a balanced fertilizer. Alternatively, you can add organic manure or compost to the soil at the beginning of the growing season to provide enough nutrients for the whole season.
Pruning
Pruning the plant Cannella erecta L. is not essential because it does not require special pruning. However, some gardeners may decide to remove the plant's dead flowers to promote more blooms. Pruning can also be done to control the plant's growth or shape. Prune sparingly by removing the tips of stems from time to time.
Propagation of Commelina erecta L.
Commelina erecta L., commonly known as the whitemouth dayflower, is a herbaceous perennial plant native to North America that belongs to the Commelinaceae family. The plant is characterized by its attractive blue flowers and is often used for ornamental purposes.
Seed Propagation
Seed propagation is a common method for propagating Commelina erecta L. To start, collect mature seed heads from fully grown plants in late summer or early fall. The seed heads should be collected before they release the seeds. After collecting the seed heads, leave them in a dry and warm place for about a week to allow the seeds to fully mature.
The seeds can be sown directly in the planting site in the spring when the soil is warm and moist. Alternatively, they can be sown indoors in pots filled with fertile soil. Sow the seeds at a depth of about 1/4 inch and keep them moist. The seeds usually germinate in 10-21 days, after which the seedlings can be transplanted to their permanent location.
Division
Division is another propagation method that can be used for Commelina erecta L. The plant has thick, fleshy roots and forms multiple crowns, making it easy to divide. The best time to divide the plant is in early spring, just before new growth emerges.
To divide Commelina erecta L., dig up the entire plant and gently separate the crowns using a sharp knife or garden fork. Each division should have a few healthy shoots and roots. Transplant the divisions into their permanent location and keep them well-watered during the first few weeks.
Cuttings
Cuttings can also be used to propagate Commelina erecta L. Take cuttings of healthy, mature stems in the spring or early summer. Cuttings should be about 4-6 inches in length and should have at least two nodes.
Remove the lower leaves and dip the cut end into rooting hormone powder. Plant the cuttings in a pot filled with moist, well-draining soil and keep them warm and humid. The cuttings will develop roots in a few weeks and can be transplanted into their permanent location.
