ROOTSTOURS FOR APPLE TRiSS 
Following is a description of the apple rootstock that we use for pr op— 
agating trees,There is a confusing tendency to call the entire Malling 
series "dwarf" trees; however they range from very small on MIX to 
standard size on MXII and XVI, Zach grower should buy a specific size 
in relation to his proposed planting distance, In contrast to the 
Malling series, Clark Dwarf—~Hibernal is an entirely different process 
of controlling tree size, using an "insert" which restricts the flow 
ee and produces early bearing in mch the same way as ringing or 
ne, 
Malling I Stoek Semi-dwarfing, producing early—bearing, medium 
sized tree, Transplants easily and grows well in 
orchard, Has proved to be a particularly good 
stock for McIntosh, Suggested planting distance, 
Boe op or sO ft, 
Malling II Stock Semi~dwarfin roducing slightly smaller tree 
than MI, Bre oe ime ‘mone prom sing of the Malling 
Siete Suggested planting distance, 20 x 25 or 
0 ft, 
Malling VII Stock Dwarfing, producing smaller tree than MII, Best 
stock for orchardists desiring a true dwarf, Trans- 
plants well, giving excellent stand of trees in 
orchard, Planting distance, 15 x 25 ft, 
Malling IX Stock True dwarf, making smallest tree of entire Malling 
series, Zarly bearing, often producing bloom on 
two-year-old trees, Most varieties on this stock 
require staking after tree begins to dear, Some 
growers plant close enough together in row to 
graft tips of branches together, Planting distance, 
£00220 OF 25 2%, 
Malling XII Stock Produces standard-sized tree, Row of trees on 
this stock will be very uniform in size and vigor 
Since roots are all of same variety, Plantire 
distance on smaller trees such as Rome and Trans— 
parent, 25 or 30 x.30 or 35 ft, 
Malling XIII 3tock Semi-dwarfing, making tree about size of those on 
MI and MII, Proved to be particularly good stock 
for Cortland, Also works very well with Jonathan 
and Golden Delicious, Suggested planting distance, 
BO ccm, ot Gy 
Malling XVI Stock Standard-sized tree giving good uniformity of size 
and vigor, Same planting distance as on MXII, 
Clark Dwarf/Hibernal Stock 3ectween Malling IX and VII in size of tree, 
Dwarfing effect is produced by stem-piece of Clark 
wood grafted between hardy Hibernal trunk and 
scion—variety top, Planting distance, 15 x 25 ft, 
Standard Stock Grown from ssed collected from processing plants, 
7 Each seedling is different from the rest, varying 
in vigor,type of rooting, hardiness,suscepti bility 
to insects and diseasea andresponse to environment, 
This is incontrast to the Malling series of stocks 
which are reproduced by layering and are therefore 
as much a variety as the Delicious or Mcintosh 
that are budded upon it,
