The plant should be fertilized every four to six weeks during the growing season. It is essential to follow the manufacturer's instructions regarding the application rate and timing to avoid over-fertilization.
Pruning of Raphia dolichocarpa Burret
Pruning of Raphia dolichocarpa Burret is necessary to remove dead or damaged fronds and promote the growth of new ones. It is best to prune the plant during the dormant season when growth is slow. Use sharp and sterile pruning tools, such as shears or a saw, to avoid injuring the plant. It is essential to remove the entire frond from its base, leaving a clean cut to prevent disease and pests.
Propagation Methods of Raphia dolichocarpa Burret
Raphia dolichocarpa Burret can be propagated both sexually and asexually.
Sexual Propagation
Propagation through seeds is a popular method for Raphia dolichocarpa Burret. The seeds should be harvested when the fruit is mature and ripe. After harvesting, the fibers surrounding the seed should be removed, and the seeds should be soaked in clean water for 48 hours to soften the seedcoat.
The seeds can be sown in a seedbed or seedling trays filled with soil and sand mixtures. The seeds should be planted at a depth of 10-15cm with the pointed end facing down. Watering should be done regularly to keep the soil moist. Germination begins after 3 to 4 weeks of sowing the seeds.
Asexual Propagation
Raphia dolichocarpa Burret can also be propagated through vegetative means like suckers, offsets, and tissue culture.
Suckers and offsets can be removed carefully from the parent plant without causing much harm to the plant. The suckers and offsets should be planted immediately at a depth of 10-15cm. Regular watering should be done to keep the soil moist. The planted suckers and offsets start growing after 1 week to several months.
The tissue culture method involves taking explants from the plant and culturing them on a sterile nutrient medium. The plantlets produced are then transferred to the soil mixture containing sand, soil, and vermiculite.
