If you are planting seeds, ensure you sow them in quality soil, provide consistent moisture, and a warm, bright location. After emergence, provide a good balance of light and moisture.
You can also propagate Combretum oyemense Exell from softwood cuttings, which should be taken from the current year's growth, with a length of about 10cm. Plant them in a well-aerated soil mix and provide constant moisture until roots form.
Alternatively, you can use tree-cores by cutting a small slice of bark from a mature branch or stump and filling it with quality soil. Ensure that it is wrapped in a moisture-retaining material to prevent the core from drying out.
Watering needs for Combretum oyemense Exell
Combretum oyemense Exell needs consistent moisture to thrive. During the growing season, water the plant at least once a week. However, be careful not to overwater as it can cause root rot. Check the soil regularly and water only when the top inch is dry.
During the dormant season, reduce watering, but do not allow the soil to dry out completely. Water only when necessary to keep the soil slightly damp.
Fertilization of Combretum oyemense Exell
Combretum oyemense Exell needs fertilization for proper growth and development. You can fertilize the plant twice a year, preferably in early spring and mid-summer.
Use a balanced fertilizer with an N-P-K ratio of 10-10-10 or equivalent. Apply the fertilizer on the soil surface, making sure not to get it on the foliage. Water the plant thoroughly after application.
Pruning Combretum oyemense Exell
Pruning is essential for promoting healthy growth and maintaining the plant's shape and size. You can prune Combretum oyemense Exell at any time of year, but it is best to do it during the dormant season to avoid shock.
Only remove dead, diseased, and damaged branches. To maintain the size and shape of the plant, trim back any branches that grow beyond the desired area.
