G’day
to all tree planters.
Now is the time to get
a few more trees in the ground before it dries
out. Make sure plants are thoroughly saturated with water prior to
planting. Prune back the leaves a bit to reduce moisture loss and
subsequent transplant shock. The soil is beginning to warm up so
root growth will be rapid if plants do not get a check. Therefore
watch the weather .....ensure your plants do not dry out when
transplanting, and in a week or two they will be putting out new root
growth.
Planting
is best timed so that plants can establish roots into
the soil before their first drought.
Trees will not survive being planted in dry soil.
March/April
May
|
Good time of the year to
plant if rainfall allows, or plants are watered in. Root
growth is more rapid over Autumn/Winter/Spring – before the following
dry Summer.
|
June/July/
August
|
Good time for bulk planting with heavier rainfalls.
|
September/
October/
November
|
Best time for frost-prone plants once there is no danger from
frosts. Warmer soil temperatiures enable plants to get established.
|
Dec/Jan/
Feb |
Traditionally not recommended as conditions too dry, but in
certain conditions it may be preferable, especially if planting in a
cold climate (South Island), and if able to water plants in.

Choosing
a Site
The
care taken in choosing the correct site selection and correctly
preparing the site are the keys to ensuring successful plant growth.
Identify problems with your site.
Consider
the following: soil type, frost exposure, wind exposure,
salt exposure, sun exposure.
Each particular type of plant has its own requirements. Look at
the place you are trying to plant up and then go looking nearby for
other similar pieces of land, and observe what grows well. They
are the plants you should be growing. Do not think you can take
plants from shade nearby and put them into full sun, however.
Every detail of habitat and site microclimate must be studied.
Often in a harsh site, there are few plants which will grow.
Given weed competition there are even less plants which will
survive. Thus look for the hardiest tougest fastest growing local
native pioneers.
SOme
introduced plants may grow well also......too well. Watch out for
potential weeds, especially climbers. As a land manager, the
number one thing you can do is to eliminate certain weeds.
Politically difficult to get on the lists, moth plant or kapok vine is
an example of something you should get rid of while you've got the
chance. Otherwise you will have a worse job later. Many
introduced plants are potential weeds. Our special local fauna is not
adapted to such plants. We must retain the balance in the favour
of the local natives, in order to have kiwi and kokako, for example.
Establish what grows naturally in the locality.
Copy nature to get the best results.
If possible first plant fast growing species (pioneers) which will shelter native trees and shrubs.
Suit
the plants for the condition of the site – not the site to the plant.
Before Planting
The
main watchpoints:
·
Eradicate weeds and grasses from your proposed
planting site approximately six weeks before planting.
This may even require spraying the area.
·
If you live in a rural locality, fencing to keep
stock out is essential.
·
Control pests.
Identify any eliminate potential problems. Rabbits, goats and possums have to be controlled prior to
planting trees to avoid damage or destruction of tender plants.
Some sites require a two-year programme of vigilant eradication
to enable young trees to grow. Possums can even be found in city gardens!
We can advise on control. . If your planting site is in the open and flat,
there is a risk of frost.
·
Before removing the plastic container in which we
have provided your tree, water the plant well.
Planting
·
Plant in clusters of same species to attract birds
and to make the overall effect look more natural see diagram below.
·
Ensure that the holes you dig are of the correct
size. Do not bury the stems
or trunks of plants any higher or lower than to the level of the potting
mix used by our nursery.
·
If necessary with bad soil, add some compost to the
base of the holes you have dug.
·
Ensure roots are balanced and pointing in the right
direction!
·
Pack soil firmly in around the root base.
·
Water thoroughly.
After Planting
· Continue with pest control. ·
Remove any weeds and grass competing for nutrients
around your young trees. This
may require either chemicals or manually removing such competitors for
up to two years. In Spring
weed at least twice
·
Water once or twice deeply in the first Summer
(Dec/Jan) if drought occurs.
