Information

The past 35-40 years has seen huge changes in fruit growing similar in nature to the computer industry evolving from mainframes to ipads. Tree training systems, rootstocks, plant densities and varieties have all changed radically. Apples have evolved from low density single leader pyramid orchards with Granny Smith and Red Delicious as varieties to modern day, high density orchards on multi-disease and pest resistant rootstocks with controlled varieties such as Honeycrunch®(Honeycrisp c.v.), KORU® (Plumac c.v.) and Envy™(Scilate c.v.). The cherry industry has evolved from Dawson as a single variety on seedling rootstocks to well over 40 varieties on clonal rootstocks.

McGrath Nurseries Ltd has been at the forefront of these changes and has been New Zealand’s leading fruit tree nurserymen for innovation and change. We have lead similar changes within the nursery industry being the first nursery to introduce individual color coding of trees, new rootstocks changing the planting densities in orchards, and importation of varieties that have increased production and marketability of fruit for our New Zealand orchardists.

While some things have changed, some very basic plant management skills remain the same but sometimes need a quick review.

The following technical information and resources are intended to be a useful tool for experienced fruit growers and beginners alike.

Caring for New Trees

The way in which trees are cared for will have an important effect on the establishment and future production of the tree. 

Ideally, plant all trees as soon as they arrive. Trees should never be allowed to dry out at any time between lifting and planting.

Please read and follow these storage and planting instructions carefully to ensure healthy trees in your orchard...

Process of Growing a Tree

McGrath Nurseries Ltd focuses the bulk of their production and sales on the production of a traditional high quality maiden tree produced by budding in a multi-year process.

We are often asked how a tree is produced and at times queried about the price of trees.  Producing a high quality tree is an extremely labour and input intensive process taking several years.  Like all horticulture, the crop is totally at risk to the elements at all times and highly trained, detail conscious staff are required to craft a tree for best results in the orchard.
