Pruning and propergation.
Why do we prune. Why do we properate? (Division).
1.Deadwood. To make more plants
2.Damaged. To tidy up or control the plant.
4 Dangling in the way.
= Deadwood, tissue changes colour, when you cut into it = the trunk/branches are green shows it’s alive. If it’s brown and brittle shows it’s dead. Maples are different, they can be red if alive or grey if dead.
If stems are damaged and a wound has appeared, you can bind it with Micropore tape to help it to heal its self.Wounds heal over to protect the plant from infection or insect attack. Wounds can take a couple of years to heal.
Grafting = Trunks can grow round something i.e., a fence, or support stick.
We use this to our advanatage when grafting roses, fruit trees etc. You can get miniture fruit trees that can have three fruits on one tree.
Damage and disease occur by = branches rubbing together. A tree can “die back” after being damaged.
Dangling = Twings growing in wrong direction. Prune any that “cross paths”.
Roses = Control long growths with flowers at the end. The hormones flow through the plant to the “growing tip”. Pruning encourages flowering lower down.
Coppicing = anything that is used as a hedging plant can be coppiced.
Pollarding = Willows = take tops off.
Hazel = can be both coppiced and pollarded.
Terms = Standard
When to prune ? Nov/Mar because the plant will be dormant as light conditions are wrong. In Spring and Summer the growing hormones are active.
What to use = Seceuters
Curved blades (blade “goes past”), by pass. For thin and flexible stems.
Parrot beak (blade and anvil), for larger and brittle stems.
Loppers = edge to edge – anvil type.
Wilkinson Sword “Rachet” based will cut thick stems well, but are expensive..
= Keep equipment clean and sharpened.
Pruning cut = diagonal, between the buds. – Internodle cut – to allow for “die back” and lessen risk of infection or damage.
1. Softwood cutting = Summer time, new growth, when pale and flexible.
2. Semi ripe
3. Hardwood cuttings = Autumn time. Ripe wood, Outer Bark cells.
In late summer, early Autumn If you look at a length of stem, you should be able to identify the three stages of development of the plant.
Layering = Hawthorne and Privit hedges can be layered, this makes the tougher and stronger.
