This plant grows best in warm temperatures, with a minimum temperature of 20°C and a maximum temperature of 30°C. In cooler temperatures, the plant may not grow as well and could suffer from frost damage. Pouzolzia guineensis auct. can tolerate high humidity and is not affected by occasional rainfall.
Soil Requirements
The plant prefers well-draining soil with a pH level of 5.5-7.5. It thrives in rich soil that is evenly moist but not waterlogged. It can grow in a variety of soils, from loam to clay, but sandy soil is the best for optimal growth. The addition of organic matter to the soil will also help in the growth of Pouzolzia guineensis auct.
Cultivation
The Pouzolzia guineensis auct. plant can be cultivated in various soils from sandy to loamy, but it thrives best in well-draining soil. It is essential to use a good-quality potting mix with some added organic matter to provide the required nutrients.
The plant requires partial to full sun, so it is best to place it in a location where it can receive sunlight for a few hours during the day. Additionally, it is ideal for the plant to be in an area where it can get good air circulation.
Watering Needs
Although the plant prefers slightly moist soil, overwatering can be harmful to it. Thus, it is best to water the plant only when the top one to two inches of soil are dry. Water the plant deeply, ensuring the soil absorbs the water well. Always ensure the plant has adequate drainage to prevent the accumulation of excess water in the soil.
Fertilization
Pouzolzia guineensis auct. plants require fertilizers during the growing season to promote leafy growth. Use a balanced, slow-release fertilizer granule to provide nutrients to the plant. Be sure to follow the instructions on the fertilizer label to avoid over-fertilizing the plant.
Additionally, it is beneficial to add some organic matter to the soil, such as compost or well-rotted manure, during the growing season to provide nutrients to the plant.
Pruning
Regular pruning of Pouzolzia guineensis auct. plants encourages dense and bushy growth whilst promoting healthy foliage. Prune any yellow or dead leaves and stems, and pinch back the tips of the plant after the flowering season to encourage more growth. You can also cut back the entire plant by a third or half to promote a fuller, more compact appearance.
It is essential to sterilize your pruning shears by cleaning them with a solution of water and bleach between cuts to prevent the spread of any diseases that may be present in the plant.
Propagation of Pouzolzia guineensis auct.
Pouzolzia guineensis auct. can be propagated through both sexual and asexual methods. The suitable time for propagation would be during the late spring or early summer when the weather is mild.
Sexual propagation
One of the common sexual propagation methods for Pouzolzia guineensis auct. is through seeds. The seeds should be collected from a mature plant, and the fruit should be left to ripen until it is brittle. Afterward, the seeds should be extracted and cleaned properly. Before planting the seeds, make sure the soil is moist enough, and the temperature is warm enough for germination to take place. It takes approximately 10 to 20 days for germination to occur.
Asexual propagation
Pouzolzia guineensis auct. can also be propagated through non-seed methods, such as cuttings. Stem cuttings should be taken from the mother plant and should be about 5-10 cm long. The leaves should be cut by half, and the lower leaves should be removed. The cutting should be dipped in hormone rooting powder and planted in a propagation mix which is well-drained and kept moist. The pot should be covered with a plastic sheet to maintain humidity and placed in an area that is shady and has a moderate temperature. After approximately 4-6 weeks, the cuttings should have enough roots to be transplanted into a bigger pot.
