Sourcing planting stock

Nurseries and plant availability

Availability of planting stock is dependant on ordering of trees well in advance. Nurseries only grow plantation forestry species to order. Usually one years notice is sufficient for plants being available but this may be extended if seed or cuttings are not available for the nursery to grow. If you are wanting a specialised line then think ahead.

Planting stock may be supplied either bare-rooted or containerised. Freight costs are in addition to the price of each plant and packaging of planting stock should be discussed with the nursery.

Containerised stock

Root distortion in container-grown trees has two different origins and may increase likelihood of windthrow in young trees:

  1. Container walls redirect and distort root development. Root trainer pots redirect roots downwards to avoid circular winding of roots. Although better than square or round pots ('tubes"), root trainers are implicated in causing a "root cage" in young trees which directs roots into a congested group of downward pointing fingers rather than a single vertical taproot and radiating lateral roots. Side slot (air-prune) containers are recommended for forestry stock as these minimise root distortion cause by the container walls and encourage fibrous root growth inside the container.
  2. Poor pricking out practices can cause root distortion in containerised stock, such as "J roots". Appraisal of nursery stock is by removing the soil media from a sample of trees and inspecting the inner root.

Both causes can be mitigated and it is recommended that the grower discusses these issues with their nursery.

Bare-rooted stock

This should have a fibrous root system. Regular wrenching in the nursery induces a more fibrous root system so that when the trees are lifted and long roots cut back, there is still plenty of root mass to supply moisture and nutrients to new growth.

The importance of seed provenance

The importance of contracting nurseries to grow from seed procured from proven trees cannot be over-emphasised. It is preferable that the nursery be supplied with the seed by the grower, who would if possible purchase the seed from a knowledgeable collector who has proven mother trees in Northland from which to collect seed. Where possible progeny should have been tested and proven to be reliable for health, growth and form in Northland.

In particular, eucalypt and cypress seedlings should be grown only from reliable and well proven seed sources. This is necessary to ensure disease and pest resistance along with adequate growth and form characteristics. It is hoped that the Northland Regional Council facilitates collections of quality seed and supply of this seed into the nursery trade.
