Pruning is best done during the spring season.
Propagation of Ehretia goetzei Gürke
Ehretia goetzei Gürke is a small tree or shrub that is native to Africa and is commonly known as "Zigzag Evodia." This plant is a great option for those who want to propagate it. One can use various methods to propagate this plant, including:
Seeds
The easiest way to propagate Zigzag Evodia is through seeds. Collect the fresh ripe fruits of the plant from the tree and remove the seeds. Rinse and clean the seeds, then soak them in warm water for a day before planting.
Use well-drained potting soil mixed with sand and peat moss to sow the seeds. Plant the seeds about 1 inch deep in the soil and keep the soil moist at all times. Within four to six weeks, the seedlings should emerge. Once the seedlings grow tall enough, they can be transplanted into individual pots or large containers.
Cuttings
Ehretia goetzei Gürke can also be propagated from stem cuttings. Cut a stem carefully from the mother plant, making sure it is about 4-6 inches long and has at least two leaves on it. Remove any flowers or fruit on the stem.
Dip the end of the stem cutting in rooting hormone, then plant it in moist potting soil. Cover the pot with a plastic bag to create a humid environment for the cutting to root in. Keep the soil moist and do not let it dry out. In four to six weeks, root formation should occur. Once the roots have grown, the new plant can be transplanted into a larger pot or outside into the garden.
Air Layering
Another propagation method for Zigzag Evodia is air layering. Air layering involves creating a small wound on the stem of the plant, placing rooting hormone on the wound, and then wrapping it in moist moss or peat moss. Once roots have developed, the new plant can be severed from the mother plant and either transplanted into soil or potted.
Propagation of Ehretia goetzei Gürke is easy and can be done using any of the three aforementioned methods. The seed propagation method is by far the easiest and most reliable method to use.
Disease and Pest Management for Ehretia goetzei Gürke
