Fruit Tree Rootstocks
Rootstocks are used to control the ultimate size of a tree, we use a wide range of rootstocks from very dwarf which are ideal for smaller gardens to very vigorous which are commonly used in traditional orchards. Rootstocks can also offer disease resistance and tolerance of difficult growing conditions.
M.27 - Very Dwarf. Produces the true mini tree, varieties reaching no more than 2 metres with little support required, excellent for the small garden. Fruit size small. Good for triploids on strong soils but will stunt diploides on poor soils.
M.9 - Dwarf. Very productive and induces good fruit size. Poor anchorage needing permanent staking. Ideal for cordons and spindles. There are over 100 M9 types and together they account for the majority of commercial orchards worldwide.
M.26 - Semi Dwarf. Requires support on most sites. Good for bush and cordons in limited spaces. Suits certain varieties well i.e Bramley and Egremont Russet. Can induce 'bare wood' in some varieties such as Cox. Susceptible to woolly aphid.
M.116 - Medium vigour. Although bred at East Malling Research Station some years ago this selection has only just become commercially available. Between MM106 and M26 in vigour this very productive rootstock has resistance to collar rot/phytophora, replant disease and woolly aphid. As productive as MM106 with 10% less vigour this is likely to prove to be an all round performer for many commercial (particularly cider) and amateur situations.
MM.106 - Semi vigorous. General purpose for most types of tree; bush, cordon and half standard. Very productive from an early age. Can succumb to collar rot or phytophora on poorly drained soils. Resistant to woolly aphid.
MM.111 - Vigorous. Produces a standard on good soils and half standard on poor soils, excellent collar rot and general disease resistance. Resistant to woolly aphid.
M.25 - Very vigorous. Ideal for half and full standard trees. Heavy crops from an early age. Not resistant to woolly aphid.
Gisela 5 - Dwarf. 50% of Colt. Ideal for commercial orchards, gardens and patio pots.
Gisela 6 - Semi Dwarf. 75% of Colt. All the attributes of Gisela 5 but for less than good soils.
Colt - Semi vigorous. Fully compatible with all varieties, will contain trees to 4 - 5 metres. Considered very productive until the arrival of Gisela. Still good for bush and half standard cherries on thin soils.
Prunus F.12.1. - Very Vigorous. The best clonal selection of mazzard for standards. Good anchorage.
Compatibility: It should be noted that there are many incompatible varieties when worked on Quince (especially Quince C). In these instances a suitable interstock should be used and Beurre Hardy, Doyenne du Comice and Old Home are suitable. The latter will also impart some resistance to Fireblight.
Quince 'C' - Dwarf. and slightly earlier into cropping.
Quince Eline® - Dwarf. Similar size to Quince 'C' but more productive and very hardy. Smoother fruit with less russetting.
Quince 'A' - Semi Vigorous. The ideal root stock for bush trees.
Pyrodwarf - Vigourous. A German selection giving something between Q.A and Pyrus communis from early observations. Probably more vigorous than claimed. Early signs are very promising due to early fruiting influence, uniformity and resistance to fireblight through its Old Home parentage.
Pyrus communis (Seedling pear) - Very vigorous. More suitable for half standard and especially standard trees.
Pyrus Kirchensaller - Very vigorous. A more uniform and productive selection of Pyrus communis.
Pixy - Semi Dwarf. Ideal for size containment in the garden. On very strong soils it still has commercial use for strong growing shy cropping varieties such as Marjories, Avalon and Excalibur.
VVA-1 - Semi Dwarf. Pixy size with better fruit size, yield and winter hardiness.
Torniel - Semi-Dwarf. A specialist rootstock for improved fruiting yield and fruit size.
Krymsk 86 - Medium. Compatible with apricots, peaches and nectarines. More tolerant of heavy wet soils with better anchorage.
Plumina ® (Ferlenain) - Semi Dwarf. A French selection with similar tree size to Pixy but improved fruit size. Grows strongly in the first few years and then settles quickly into regular cropping. Some suckers.
Jaspi ® - Semi Vigorous. A french stock, untested as yet but with St Julien 'A' vigour and good resistance to root aphixiation in wet situations.
Wavit - Semi Vigorous. A robust disease resistant medium vigour, free standing and non suckering rootstock for plum, gage and damson, mirabelles and apricots proven to suit a wide range of soils and conditions. (SJA -10%)
St. Julien 'A' - Semi Vigorous. This is fully compatible with all plums, damsons, gages, peaches, nectarines and apricots and many ornamental prunus species. Good yield influence. Not suitable for poorly drained soils.
Brompton - Vigorous. Very suitable for standards, does not sucker and fully compatible with all varieties unlike its predecessor such as Myroblan.
All our vines are grafted onto 'SO4' rootstock which is vigorous, suiting a range of soils and UK climate conditions.
