Today Tuesday 4th June, 2013, my morning session was with Ms.Lisa Short on Plant Propagation Unit. She was guiding us on Evergreen Hardwood Cuttings.
Evergreen hardwood cuttings are used for the propagation of conifers. These cuttings can be slow to root, on average taking between two to twelve months. The plant that I did in class was Juniper x media blaauw. The mixing of media is fill in the tray to the top with potting mix the level off with a board and mix together with Seradix the Root Forming Hormone on Hardwood and Liba 10,000 of hormone forming. Then make a hole with a dibber in the media and plant the cuttings. Cutting length are usually between 5 - 15cm long. Cutting type are usually heel cuttings are commonly used. The cutting treatment was rooting hormones and fungicides dips can be beneficial.
The cuting environment are humidity levels must be maintained and misting unit or humidity tent is recommended. There are three types of cutting such as stem cutting that you will make are simply shape of stem cuttings. The other type of cutting are heel cuttings and mallet cutting which the nodal are of a plant stem contains a greater amount of carbohydrates or food reserves. The availability of food increases the likelihood of root development during propagation. The heel cuttings and mallet cuttings will take advantages of this and can be useful for difficult to propaganate plants.
The weather was wet and raining by 5 degrees Celcius. Its very cool and cloudy in the morning.
