Despite its beneficial uses, Wedelia Jacq. also poses a threat as an invasive species in some regions. It can rapidly spread and displace native vegetation and disrupt ecosystems. Therefore, it is important to manage and control its growth and spread.
Light Requirements
Wedelia Jacq. thrives in full sunlight conditions or light shade. Bright filtered sunlight is the best option for the healthy growth of the plant.
Temperature Requirements
The best temperature range for Wedelia Jacq. is between 21°C to 30°C. It cannot withstand winters with freezing temperatures or too much cold. It is a tropical plant and thus requires warm weather to grow.
Soil Requirements
Wedelia Jacq. can thrive in various types of soils, ranging from sandy soils to loamy or clayey soils. However, it prefers well-drained soils with sufficient organic matter. The soil pH range for healthy growth is between 5.5 to 7.5. The plant cannot tolerate waterlogged soil conditions.
Cultivation Methods
Wedelia Jacq. is a hardy plant that is easy to grow and cultivate. It thrives in warm, sunny areas and is tolerant of a variety of soil types. It is typically propagated through stem cuttings or by division of established plants. When planting, ensure that there is adequate space between the plants, as Wedelia Jacq. can spread quite rapidly.
Watering Needs
Wedelia Jacq. requires frequent watering, especially during periods of drought or when grown in containers. However, it is important not to overwater the plant, as this can lead to root rot. The soil should be kept slightly moist but not waterlogged. To determine if the plant needs water, stick your finger in the soil. If it feels dry to the touch, it is time to water the plant.
Fertilization
Wedelia Jacq. benefits from regular fertilization, especially during the growing season. A balanced fertilizer with equal parts nitrogen, phosphorus and potassium is recommended. Fertilize the plant once per month, following the manufacturer’s instructions for application rates. Avoid applying too much fertilizer, as this can burn the plant’s roots and foliage.
Pruning
Pruning Wedelia Jacq. is necessary to keep the plant looking neat and tidy. It is best to prune the plant in the spring, just before the growing season begins. Use sharp pruning shears to remove any dead or damaged branches as well as any new growth that is growing in an undesirable direction. It is also possible to shear the plant back to promote bushier growth and prevent it from becoming leggy.
Propagation of Wedelia Jacq.
Propagating Wedelia Jacq. is an easy process. You don't need any special equipment or tools to do it. This plant can be propagated through seeds, cuttings, and division.
Propagation through Seeds
You can propagate Wedelia Jacq. through seeds, which are readily available from the flowers of the plant. Collect the seeds during the peak season and remove any debris. Plant the seeds in well-draining soil, and keep the soil moist. Place the pot in a bright area. Germination should occur within a few weeks.
Propagation through Cuttings
Another method of propagation is through cuttings. Take cuttings in the spring from a healthy plant. Cut a 3-4 inch piece from the stem, making sure it has a few leaves and nodes. Dip the cut end into rooting hormone before planting in well-draining soil. Cover the pot with a plastic bag. After two to three weeks, roots should have developed. You can remove the plastic bag once the roots are seen, and place the new plant in a sunny area.
Propagation through Division
The third propagation method is through division. This is best done in the spring. Take the mature plant out of the soil and remove any dead foliage and debris. Split the plant into two or three clumps, ensuring that each clump has its roots. Replant each clump into separate pots using well-draining soil. Keep the pots in a sunny spot and moisten the soil regularly.
With these three methods, you will have no trouble propagating Wedelia Jacq. and enjoying its vibrant and bright flowers.
