Light Requirements
Parinari ingangensis Pellegr. thrives in well-lit areas, however, it can also tolerate partial shade conditions. Direct sun exposure for extended periods of time should be avoided as it may cause the leaves to wilt or even burn.
Temperature Requirements
Parinari ingangensis Pellegr. is a tropical plant, thus it requires warm temperatures for optimal growth. The ideal temperature range for this plant is between 20°C to 30°C. Temperatures below 15°C may cause the plant to enter dormancy, while temperatures above 40°C may lead to leaf shedding.
Soil Requirements
Parinari ingangensis Pellegr. prefers well-draining soils with a pH ranging from slightly acidic to neutral (pH 5.5-7.2). The soil should not be too compact as it may hinder root growth. This plant benefits from soil enriched with organic matter, thus it is recommended to mix compost or other organic materials into the soil prior to planting.
Cultivation Methods
Parinari ingangensis Pellegr. is a tropical tree that is native to Central and West Africa, and it grows best in warm and humid conditions with temperatures between 18 and 32°C. It can be cultivated from seeds or stem cuttings.
To grow from seeds, the seeds should be soaked in water for 2 to 3 days to soften the hard coat before planting. The soil should be well-draining and fertile. The seeds should be planted 2 to 3 cm deep, and 15 to 20 cm apart. It is recommended to plant the seeds during the warm and rainy season.
For stem cuttings, select healthy stems from the parent tree and cut them into 10 to 15 cm lengths. Remove any leaves on the lower half of the stem and dip the cuttings in rooting hormone powder. Plant the cuttings in well-draining soil and keep them in a warm and humid place until they take root.
Watering Needs
Parinari ingangensis Pellegr. requires regular watering, especially during the dry months. Water the plant deeply once a week, making sure the soil is moist but not waterlogged. The plant should not be allowed to dry out completely as it may affect its growth and development. It is important to ensure good drainage to prevent waterlogging, which can lead to root rot.
Fertilization
Parinari ingangensis Pellegr. requires regular fertilization to maintain healthy growth and development. Fertilize the plant every four to six months with a balanced fertilizer that includes nitrogen, phosphorous, and potassium. It is advisable to apply the fertilizer during the rainy season when the plant is actively growing.
Avoid using excessive amounts of fertilizer as this may lead to the accumulation of salts, which can damage the roots and affect the plant's growth. Follow the instructions on the fertilizer package for best results.
Pruning
Parinari ingangensis Pellegr. requires minimal pruning to maintain its shape and remove any dead or diseased branches. Prune the plant during the dry season to avoid excessive sap bleeding. Use clean and sharp pruning tools to avoid damaging the plant.
Remove any dead, damaged or diseased branches, shoots or leaves to maintain the plant's health and promote new growth. Additionally, trim the tree's branches to control the plant's size and shape. Avoid removing more than one-third of the plant's overall mass to avoid stunting the growth of the tree.
Propagation of Parinari ingangensis Pellegr.
Parinari ingangensis Pellegr. can be propagated through both seed and vegetative propagation methods.
Seed Propagation
Freshly collected seeds from the plant can be used for propagation. The seeds should be cleaned and sown in well-draining soil mix. A light layer of soil should be spread over the seeds and watered thoroughly. The pots should be kept in a warm, bright place and watered regularly. Germination can take anywhere between 2 to 4 weeks.
Vegetative Propagation
Parinari ingangensis Pellegr. can also be propagated through vegetative methods, such as stem cuttings and air layering. Stem cuttings should be taken from healthy plants and should have at least two nodes. Cuttings should be treated with rooting hormone and propagated in well-draining soil. Air layering also involves treating a portion of a stem with rooting hormone and wrapping it with moist sphagnum moss and plastic wrap until roots appear.
Parinari ingangensis Pellegr. can be slow growing, and it’s important to use healthy and vigorous material for propagation.
