The plant requires moderate watering and prefers full sun but can tolerate some shade. It is also resistant to pests and diseases, making it a low-maintenance plant.
Light Requirements
Pupalia erecta is a tropical plant that grows best in full sun to partial shade. It requires at least six hours of sunlight each day to grow properly. In areas with intense heat, partial shade is preferable to avoid scorching of leaves.
Temperature Requirements
Pupalia erecta is adapted to warm temperatures and grows best within a temperature range of 18°C to 34°C. The plant is very sensitive to frost and cannot tolerate temperatures below 10°C. Extreme heat and cold temperatures may cause damage or death to the plant.
Soil Requirements
The plant prefers well-drained soils with moderate fertility. It tolerates a wide range of soil pH, from slightly acidic to slightly alkaline, with a preferred range of 5.5 to 7.5 pH. Pupalia erecta can grow in sandy soils, loamy soils, or clay soils as long as the soil is not waterlogged.
Cultivation Methods
The Pupalia erecta Suess. is a hardy plant that is relatively easy to grow. It is drought-resistant and can tolerate a wide range of soil conditions, including poor and sandy soils. The plant prefers full sun and can grow up to a height of 2 meters if left unpruned. It is a perennial plant, which means that it can survive for several years under the right conditions.
Watering Needs
The Pupalia erecta Suess. has low to moderate watering needs. When establishing the plant, ensure that the soil is consistently moist until the roots become established. Once the plant is established, reduce the watering frequency to once a week or every 10 days. However, adjust the watering frequency based on the prevailing weather conditions. During hot and dry spells, water the plant more frequently to prevent the soil from drying out.
Fertilization
The Pupalia erecta Suess. is not a heavy feeder, and you do not need to fertilize it frequently. However, you can apply a balanced fertilizer, such as a 10-10-10 NPK ratio, once every three months during the growing season. Avoid applying fertilizer during the dormant season, as the plant does not require additional nutrients at this time. Too much fertilizer can lead to lush foliage growth at the expense of the flowers, so be cautious when applying fertilizers.
Pruning
The Pupalia erecta Suess. can grow quite tall if left unpruned, and the plant may require pruning to keep it within manageable size limits. Pruning is best done during the dormant season when the plant is not actively growing. Cut back any branches or shoots that have outgrown their allotted space, or remove damaged or diseased branches. You can also shape the plant to your desired form during pruning. Use a sharp, clean pair of pruning shears to prevent infecting the plant with diseases.
Propagation of Pupalia erecta Suess.
Pupalia erecta Suess., popularly known as forest Burr, is a highly preferred plant species due to its medicinal properties and insecticidal properties. The propagation of these plants can be done through various methods.
Propagation through Seeds
The most commonly used propagation method for Pupalia erecta Suess. is through the use of seeds. The plant produces small, brown, and triangular seeds, which can be collected from fruit capsules. Collect only mature seeds that are fully dried and store them in a cool and dry place until required for planting.
Direct Sowing
The seeds should be sown directly in the prepared soil during the rainy season, making sure to only cover them with a thin layer of soil. Water the soil frequently to maintain moisture levels until the seed germinates, which should occur within 4-5 days.
Transplantation
When the seedlings grow about 2-3 inches tall with 1-2 sets of true leaves, they can be transplanted to a more permanent location. Transplant the seedlings in a spacious pot or a bed with well-drained loamy soil with a neutral pH level and full sunlight. Keep the soil moist, but be sure not to overwater during the initial stages.
Propagation through Stem Cuttings
Propagation through stem cuttings should be done during the monsoon season. The mature branches of the plant must be selected, and the cutting taken should be 3-4 inches long. Cut at a 45-degree angle and remove any leaves from the bottom of the cutting. Dip the cutting in rooting hormone powder before planting in moist soil. Keep the soil moist, but do not overwater. Roots should form within 15-20 days.
Conclusion
Pupalia erecta Suess. is an essential crop that possesses numerous medicinal and therapeutic values, making it a highly demanded plant. As such, propagation methods are critical to ensuring the continuous availability of this plant. By following the above propagation methods, gardeners and farmers can successfully propagate Pupalia erecta Suess. and produce healthy, vibrant plants.
