Grafting After Care

In the weeks and months after completing the graft it is important to check back and follow up with basic care to ensure the graft stays healthy and has the best chance for success.
  • It is usually obvious after a couple of weeks if the graft has failed as it will have dried and shrunken. If the wood looks alive and the buds are full or opening then there is a good chance your graft will take.
  • Remove active growth and buds from below the graft point as this will take energy required by the healing graft.
  • If any of the buds on the freshly grafted wood are blossoms then these should be removed. Just pinch them off carefully with fingernails or clip with secateurs. This allows the branch to focus on healing the union and prevents any breakage caused by heavy fruit. This may be necessary on the following year also, depending on the style and state of the graft.
  • When the graft is part of a larger tree consider periodic pruning or bending down of old wood to encourage development of grafted part(s)
  • After several months check grafting tape / bindings are not strangling / girdling the healing graft. Some tapes are biodegradable and will split or peel after exposure to summer sun, others require manual splitting with a sharp blade to release the pressure.
  • Excessive sun and wind exposure can dessicate or dislodge grafts. If your rootstock is in a pot keep it in a sheltered location until the union is solid. A high humidity environment is ideal.

Wood is cut and graded in June for dispatch in July – August. On receipt, scion wood will need to be stored refrigerated until the appropriate local grafting time.

Length: 150 – 170mm with 3 - 4 buds

Diameter: 5 – 12mm


Grafting is the process of adding part of a known, desirable tree onto existing, growing roots of a similar species. This process offers many benefits such as having many types of apple on a single tree or influencing the characteristics of the tree such as size, soil requirements and disease resistance.

Grafting calendar

There are 2 main activities related to grafting that are season and weather specific.
  1. Collecting desired varieties of scion wood from healthy trees while they are dormant. For deciduous fruit and nut trees this is mid winter or late June to July in New Zealand
  2. Grafting the stored scions onto the appropriate rootstocks in early to mid spring when growth is commencing. Here in North Canterbury this is from early August to to mid October.

Correct timing is only part of the grafting process. Make sure you familiarise yourself with the technique, compatibility and after care for the best results.

Rootstock compatibility for different types of tree

Scions of desirable species must be grafted onto a suitable, compatible root system or ultimately the graft with be rejected by the host tree.
The roots determine to size, growth rate and suitable soil conditions for the tree while the scion controls the flowers and fruit type and timing.
Most are only self compatible and so apple must be grafted to apple but as usual there are exceptions such as almonds onto peach.
