The Rootstock: The Foundation of Your Orchard
We continuously evaluate new and promising rootstocks, looking for those that are hardier, more disease resistant, tolerant of various soil conditions, and impart dwarfing or other desirable features. Our testing, along with that taking place at breeders and universities nationwide, will provide you with tomorrow’s rootstocks. As breakthroughs occur, we will  pass along pertinent information to you.

 Apple Rootstocks Minimize

 Malling 7
Malling 7 produces an open spreading semi-dwarf apple tree. It’s a sturdy, disease resistant, winter hardy, uniform, productive rootstock that adapts well and transplants easily. It does beast on deep, fertile, well-drained soils that retain consistent moisture. Anchorage problems with some verities and heavy suckering are its most serious faults. It is resistant to Collar Rot but susceptible to Wooly Aphids.  

Malling 9
Selected at East Malling from number of stocks of Juane de Mertz, M9 is a true dwarfing rootstocks. Useful for high-density plantings, it induces extremely heavy, early cropping. We offer several clones of M9 including EMLA , NAKB T.337, Nicoli 29, Pajam 1 (Lancep), and Pajam 2 (Cepiland). The variation of tree size among these various clones is small and grower’s cultural practices will play a greater role in determining final tree size. M9 is susceptible to Fireblight and Wooly Apple Aphid and highly tolerant to Collar Rot. Fruit tends to be larger than fruit from other rootstocks. M9 requires fertile soil with a consistent, ample moisture supply. Irrigation is strongly recommended. This rootstock must be supported by individual stakes or wire trellis because of the brittle roots.

Malling 26
Bred at East mailing from an M9 and very vigorous M16 cross, it is for high density plantings. M26 sizes between M9 and M7. Spur verities on M26 produce a dwarf tree similar to M0, but with better anchorage. Slightly less vigorous than M7, M26 produces superior quality fruit, cropping early. We suggest support for trees on M26, although some growers are going without. M26 promotes very heavy early beating on most verities and tends to stimulate large fruit size. It is hardy and, although it is adaptable to most soils, it is highly susceptible to collar Rot and should not be planted on wet or infected soils. M26 is also highly susceptible to Fireblight, and cautions should be taken when using this rootstock with blight-sensitive cultivars.

Budagovsky 9 (Bud 9)
A promising rootstock which is a cross of M9 X Red Standard. Tree size is slightly larger than M9. Tress of Bud 9 are precocious and yield good fruit size. It is hardier than M9 and produces few burr knots or root suckers. Bud 9 has disease susceptibility similar to M9 .

Mark (formerly Mac-9)
Developed from a series of apple rootstocks known as (MAC) Michigan Apple Clones by Dr. Robert Carlson, Michigan State University.  Tree sizes are between M9 and M26. It is productive with good precocity. To avoid drought stress, Mark should be planted on soils that retain moisture. It is susceptible to Fireblight and Wooly Apple Aphid. Mark has a greater tolerance to flooding than M9, making it a good choice for heavier soils.

Cornell-Geneva 30
a cross of Robusta 5 X M9, CG.30 is similar to M7 in tree size but is much more precocious and productive. CG.30 has fewer root sucker and burr knots than M7. CG.30 provides excellent anchorage, is resistant to Fireblight, and tolerant to collar rot.

A heavy-bearing, well-anchored rootstock. It makes a tree somewhat larger than M7, and it rarely produces root suckers. MM106 is the outstanding stock in the semi-dwarf group in its ability to stimulate early and very heavy production of the scion variety. Years of grower experience has established that MM106 is ideal for spur types, particularity Red Delicious because of its precocity, tree size, and precocity, tree size, and productivity. MM106 is somewhat susceptible to Collar Rot and Wooly Aphids, but field experience has demonstrated that these problems are minor and controllable.

Quite upright with wide crotch angles. Best anchored of all dwarfing rootstocks. Very tolerant to drought and high soil temperatures. Early produces root suckers. Slower to come into bearing than M7 or MM106. It is the best semi-dwarf stock for heavy, poorly drained soil types. Quite resistant to Collar Rot. Recommended where vigorous growth is needed to offset poorer cropping capacity of dry, sandy soils.  

 Pear Rootstocks Minimize

Old Home X Farmingdale
OH X F selections are resistant to Fireblight and pear Decline. They are productive with good compatibility and anchorage.

OH X F#18-A very Vigorous selection used for Asian pear verities

OH X F#97-A very Vigorous selection producing a tree about the same size as Domestic Pear Seedling.

OH X F#333 & OH X F #282- Semi standard selections producing a tree about 70% of Domestic Pear Seedling.

 Plum Rootstocks Minimize

Myrobolan Seedling
This rootstock and selections from it are widely used for European plum varieties. It is compatible with a wide range of cultivars, and particularly adaptable to heavier soils.

Marianna 2624
A selection of Marianna seedling from the University of California with many similar characteristics of Myrobolan, but offering greater resistance to Oak Root. Rot and Tomato Ring Spot Virus.

 Apricot Rootstock Minimize

We use the Manchurian hardy apricot for all apricots. Its hardiness and compatibility have been excellent. Peach is sometimes used for apricot, but compatibility can be a problem with some varieties such as Goldcot. 

 Peach Rootstocks Minimize

Lovell Seedling
Lovell has proved to be a very dependable standard peach rootstock. It provides a long lived tree and gives a high degree of disease resistance. This is especially true in the South and Eastern states, and on replanted peach sites. Not resistant to nematodes.

Bailey Seedling
A new and increasingly popular peach rootstock originating in Iowa that is very cold hardy. Baily develops an abundant root system and is resistant to root lesion nematodes. We like the results to date with Bailey for peach.

 Cherry Rootstocks Minimize

Mazzard Seedling

Mazzard is a wild cherry rootstock best suited for sweet cherry and tart cherry planted on heavier soil types. It makes a bigger tree than Prunus Mahaleb. More Tolerant of wet soils and more compatible with various sweet cherry varieties. Especially well anchored. Quite hardy but not as hardy as Mahaleb.


Mahaleb Seedling

Standard rootstock for Montmorency cherries. Hardier than Mazzard, makes a smaller tree. More tolerant of drought and sandy soils but less tolerant of wet conditions. Hardy, well anchored and widely adaptable


MxM Cherry Rootstocks

MxM Cherry Rootstock Series stands for Mahaleb crossed with Mazzard. These crosses are open pollinated made back in the 60’s by Lyle A. Brooks of Daybreak Nursery in Oregon. The numbering system has nothing to do with the growth habit of the rootstock, they are only selection numbers of seedlings. The objectives of these crosses were to select hybrids to be clones that had the desirable characteristics of both Mahaleb and Mazzard for dwarfing rootstocks that would be disease resistant and tolerate various soil types.



More vigorous than Mazzard seedling, and makes a large tough, well-anchored, early bearing and productive tree. It has strong resistance to Grown Gall, Collar Rot, and Bacterial Canker.


MxM 60
Produces a tree that’s 90% of Mazzard seedling, and is more precocious and productive. It is adaptable to a wide range of soils from sand to heavy clay, with excellent resistance to Crown Gall, Collar Rot, and Bacterial Canker.
