Scionwood and Rootstock
The following varieties of scion wood will be available for grafting in August/September and will be made available and posted out in August, it will then need to be stored well wrapped (as delivered to you)in either a dark moist outside situation, or preferably in a refrigerator. The cost per length of scion wood (200mm enough for 4-5 grafts)is $3.00 plus postage(multiple pieces will fit into a posty bag). Scion wood is available for non commercial purposes only.

Rootstock (apple/plum/peach/pear quince/inter stocked quince)
Apple rootstock descriptions (please be aware that the sizes indicated for the final tree size are indicators only and variety of scion plays a part in determining the final height) For those of you keen enough to learn the ancient art of grafting/budding you will need to consider the following.
Attending a short course/demonstration on grafting these are available usually in early spring for grafting or mid summer for budding.
Apple rootstock descriptions.
Northern Spy (NS)
Northern Spy rootstock best suited for wetter ground and clay, produces trees to 3-5m.
ORIGINS: A seeding that originated in east Bloomfield in western New York in 1828. At this time it was prized for its excellent and long keeping fruit.
ORCHARD HABITAT: Northern spy is a very popular rootstock with Australian orchardists due to its good resistance to Wooly aphids. Northern Spy produces medium sized trees of good cropping which begins at a reasonably young tree age. Trees on Northern Spy tend to be shallow rooted and will often develop a one sided root system often preferring good soil conditions. Staking is not required for trees of this rootstock.
M 793 produces trees to 4-6m. Less precocious and less productive than MM.106 with about 30% larger tree size.
ORIGINS: Merton 793 (M793) is a cross between M.2 and Northern Spy, by the John Innes Horticultural institute in Merton, England.
Introduced into New Zealand in 1941 for preliminary trials. Special attention was paid to the resistance of this range of stocks to Collar Rot and Wooly Aphids.
ORCHARD HABITAT: M.793 produces trees that are larger than Northern Spy and better adapted to a wider range of soil types. M.793 produces trees that crop earlier and heavier than Northern Spy. Resistance to Wooly aphids is excellent.
M.9 Dwarf fruit tree growing to 3m. Suits well drained, fertile soils. Not suitable for heavy clay soils.
ORIGINS: Selected as a chance seedling of 'Jaune de Metz", in France in the late 1870's. M.9 was on of the first rootstocks collected by the East Mailing Research Station and given the number '9' which was later replaced by the name Malling 9.
ORCHARD HABITAT: A dwarfing rootstock that induces early cropping on young trees. The fruit on scion varieties with M.9 rootstocks are larger and ripen earlier especially when the trees are young. M.9 is adaptable to a wide range of soil types, but is reported to be unsuitable for dry, sandy soils. It can tolerate a heavier soil type and wetter soil conditions. M.9 has a brittle root system that rarely suckers.
M26 Dwarf fruit tree growing from 2-3m Recommended for small gardens or for espaliering Hardier and quicker growing than M9.
ORIGINS: A seedling cross between M.16 x M.9 that was raised in 1929. the seedling was introduced by the East Malling research Station in 1959.
ORCHARD HABITAT: A semi-dwarfing or intermediate vigor rootstock. It produces a tree that is larger than M.9, but smaller than MM.106 and also M.7. when compared to M.7, M.26 has produced superior fruit in quality , and induces cropping at a younger age. Trees on M.26 can produce fruit with lower calcium levels that trees on other rootstocks.
The root system is brittle, but not as brittle as M.9. Trees on M.26 may require staking especially if planted in windy areas. Planting the trees 40-50mm lower than the nursery can help overcome the need for staking. (see notes at end of rootstock information). M.26 roots produce a few suckers, but those produced are vigorous. M.26 is reported to be intolerant of extended wet soil conditions.
MM106 Semi dwarf fruit tree growing to 4.5m. Good for most soils except poor draining sites.
ORIGINS: A cross between Northern Spy x M.1.
ORCHARD HABITAT: MM.106 is a rootstock that tends to be more sensitive to soil moisture levels than many rootstocks especially if the soils are poorly aerated. On dry sandy soils MM.106 will produce a tree of smaller size than M.7. On more fertile soils MM.106 will produce a tree of similar height to MM.111. MM.106 does not sucker and is resistant to Wooly Aphids, producing trees with moderate vigor and heavy cropping potential. Trees on MM.106 are reported to be resistant to potassium deficiency, but can occasionally suffer from magnesium deficiency. trees on MM.106 adapt well to a wide range of soil types and climatic conditions, making it a very popular rootstock worldwide.
Pear rootstock descriptions.
Quince rootstock for pears.
Quince BA 29 a Provence quince from France and the most common quince in New Zealand.
Widely used as a rootstock for pears it is semi-dwarfing, and most pear varieties benefit from having an interstock of an old pear variety (Beurre Hardy) which acts as a buffer between the two. Whilst a pear variety can be grafted straight onto the BA29 further down the life of the tree problems can develop immediately around the graft union.
This is a Quince BA29 rootstock with a 300mm+ Beurre Hardy pear interstock grafted to it, this enables the grafter to either graft or bud straight onto the interstock, and is compatible to all pears.
Plum rootstock descriptions.
A widely adaptable standard plum rootstock with mild suckering. Particularly adaptable to heavier soils with a excellent anchorage. Tree to 4m. The Myrobalam plum, Prunus cerasifera, is native to Asia but has been naturalized across Europe to Great Britain. It is small tree or large bush that is variable in leaf and flower colour and in growth habits. Prunus cerasifera cultivars with purple foliage are widely used landscaping plants, commonly referred to as purple-leaved plums. Trees have fragrant white to pink flowers, followed by small, cherry-sized red or yellow fruits that are used by wildlife as food. another name for Prunus cerasifera is a cherry plum. In its native habitat, fruits are used to make jams, sweets and stewed fruit drinks.
Myrobalam plum rootstocks can tolerate poor growing and soil conditions such as root asphyxia, leaf yellowing caused by low iron levels, and unfavourable salinity levels. they also have resistance to pathogenic nematodes that harm roots and to pathogens such as fungi and bacteria that live in the soil. Some incompatibility with almonds, prunes subject to brown line on the rootstock.
