Rootstocks
In May of 2007, Traas Nursery of Langley, B.C.,
closed. Traas Nursery had been producing rootstocks for over 50 years.
This meant propagators of fruit trees have had to find other sources. Some of
the replacement rootstock came from Holland and some from the USA.
Breaking news ... as of December 22, 2011,
Many rootstocks cannot be imported from Europe . Malus, Pyrus, Prunus, Citrus,
Olea, and much more are ALL restricted from the EU and many other countries
because of the threat of a fairly serious wood-boring pest. The exception is
any material that is 10mm or thinner at its widest point.
These regulations come into effect Dec. 22, 2011, and
there is a VERY short grace period where shipments of material delayed in transit
from restricted countries can still enter Canada.
Take a look at the links below (particularly the appendices of the Directive
11-01) for more information.
Malus spp. has been restricted entry into Canada, as it is a host species of
Anoplophora spp. A directive to prevent the entry and spread of Anoplophora
will be implemented on December 22nd, 2012,
D-11-01:
Phytosanitary Requirements for Plants for Planting and Fresh Branches to
Prevent the Entry and Spread of Anoplophora spp.
Please find below the weblink to the directive as well as the industry
bulletin that was sent out in November.

As of June 2011, we do not have anyone on the west coast importing r/s.
Ken Roth of New Hamburg, Ontario 'ken' and the symbol for 'at' and 'silvercreeknursery.ca' will be taking orders for rootstocks for those living in the East..
Ken Roth can deal only with customers in Ontario, Quebec, New Brunswick and Nova Scotia. For importing regulations (especially Gypsy Moth), he does not take orders for B.C., The Prairies, Newfoundland, or Prince Edward Island.
On December 15, 2011, Ken told me his deadline for accepting orders is December 31, 2011. At this time he will be importing EMLA 27, EMLA 106, OHxF 97, Prunus cerasifera, P. avium, and P. mahaleb in 2012..
Depending upon the demand,
the following rootstocks may be available: - for apple: M9 (dwarf), Bud 9 (dwarf
hardy), M26 (semi-dwarf), M7, MM106, M111, Antonovka (hardy), and Ranetka (very
hardy) - approximately $4 per rootstock. It is cheaper if you buy a full bundle
of 50 rootstocks of one kind.
For pear and Medlar: Quince A at about $3 per rootstock; for plum and peach:
St Julien A at about $4.
Prices will vary each year.
The price is dependent on the base price plus fumigating, packaging, shipping, handling, brokerage, HST, and the value of the Canadian $ vs the US $. They (Ken and Stu) won't know the exact price until the rootstocks arrive and the bills are paid.
Another source of small numbers of rootstocks is the B C Fruit Testers Annual General Meeting (March 17, 2012). See 'Events' on this website.
The final size of your tree on any of these rootstocks will depend on the vigour of the scion, soil type, amount of care given to the young tree (hours of sunlight, fertilizer, water, lime), pruning (summer versus winter) and whether it was staked properly.
An apple variety on M9 rootstock will produce a tree approximately 35% of a seedling tree, a tree on Bud 9 will produce a tree approximately 40% of a seedling tree, a tree on M26 will produce a tree approximately 55% of a seedling tree, a tree on M7 will produce a tree approximately 60% of a seedling tree, and a tree on MM106 will produce a tree approximately 70% of a seedling tree, a tree on MM111 will produce a tree approximately 80% of a seedling tree, and a tree on Antonovka will be 65-85% of a seedling tree. Assume a seedling tree will grow to 30'. Sometimes I graft M9 interstems on the MM106 and MM111 r/s to reduce the size and to have a free-standing tree.
But remember, as I stated above, estimating the final size of a grafted tree is a bit of a crap-shoot!!! There are so many variables.
Rootstock characteristics:
the following information is from 'Intensive Orchard Management' by Bruce Barritt,
Washington State University. 1992.
M9: dwarf, precocious (sets fruit early), brittle roots, must be staked for
the life of the tree
Bud 9: dwarf, hardy, precocious, must be staked for the life of the tree.
M26: semi-dwarf, not as precocious as M9, more winter-hardy than M9, susceptible
to collar rot.
M7: semi-dwarf, not as precocious as M26, less winter-hardy than M26, better
for wet soils.
MM106: 3/4 x standard, no staking needed, not good for wet soils.
MM111: 3/4 x standard, more winter hardy than MM106, best for dry soils, also
good for wet soils, no staking needed.
Antonovka: 3/4 x standard, hardy, no staking needed.
Quince A will need an interstem of Old Home or Beurre Hardy between the rootstock and many pear varieties. For a list of pear varieties compatible with quince A rootstock, see the NCGR Corvallis Pyrus Catalogue:
http://www.ars-grin.gov/cor/catalogs/pyrcompatible.html
I graft the rootstocks in March and April, put them into one gallon pots in raised beds and fertilize them with Osmocote (slow-release 14-14-14). The raised beds have an automatic watering system. By September, these grafted trees are ready for sale as one-year whips (near right). A one-year whip is sometimes called a 'maiden'. If I grow it for a second year, it will be branched (far right). |

The apple tree must be dormant (no leaves) and the buds must not have started to swell – December to February in south coastal B.C.
Ideally, the tree should be free-of-disease.
The earlier you cut the scions, the longer you have to store them so in zones 6-7-8 February is a good time to cut scions and you can graft in March.
Wait for a dry day!
The best scionwood is the wood which grew last year (2011). If you look closely at a branch of an apple tree – start looking at the very tip of the branch! Let your glance move slowly down the branch – first you will see the buds are quite far apart then they get closer and closer together and you will see a ring or rings around the branch. This is the ‘annual ring’ (also known as ‘bud scale scar’) and marks the point where growth started last year.
If you continue to glance further down the branch, you’ll see another annual ring - this marks the start of growth in 2010. Keep doing this and you will be able to tell how old the branch is.
Your scionwood should be wood which grew last year (2011). Now some scionwood is better than other scionwood.
The best scionwood is wood which is growing on the sunny side of the tree, up in the canopy, coming UP off the main branch at about 45° to 60°.
Wood hanging down is not good scionwood; wood growing horizontally is not good scionwood; wood growing straight up (water shoots) is not good scionwood.
The year’s growth should be 6-12” long and about pencil thickness (5/16”)
Cut the scion at the annual ring. Cut off the top bud and discard it. Label the scions with the name of the apple variety (using waterproof ink).
Barely moisten a paper towel – just a few drops of water scattered around the paper towel and wrap the scions in it. Put the wrapped scions in a plastic bag, close the bag tightly with a tie and store the bag in the bottom vegetable drawer of the refrigerator or similar cold, dry environment (1-3°C/33-37°F). Do not store apples or other ripening fruit in the fridge while you are storing scionwood.
Some reasons: watershoots have a lot of auxins and auxins will slow down the fruiting of your new tree plus they are too vegetative and contain too few carbohydrates.
Terminal buds produce auxin
(a hormone) so cut off the terminal bud and don’t make it part of your
three-bud scion.
Horizontal branches have lots of FRUIT buds and you want LEAF buds to make your
new tree grow in the first year.
Wood which hangs down is weak wood.
If the new growth is only two or three inches, this will be weak wood and it
is difficult to get a good three-bud scion.
A three-bud scion gives you three chances for success – you only need
one bud to grow, so one of the three buds must grow to make your new tree. You
can use a two-bud scion, but you’ve reduced your odds for success. You
can even use a one-bud scion, but if that bud does not grow you’ve had
it!
If your paper towel is wet rather than barely damp, mould will grow on your
scion.
The bottom vegetable drawer of the fridge is least affected by the frost-free cycling. An old non frost-free fridge is better for storing scionwood if you have one. The cooler, the better, but don’t store scionwood in the freezer!
Ripening fruit produces ethylene and ethylene will kill the buds on the scionwood. The union will heal, but the buds will not grow.
If you have a friend or a relative who has a really good apple tree, just ask if you can collect some scionwood. Graft the scion on to an apple rootstock and you’ll have a tree which produces apples exactly like the one you admired … and you’ll have a new hobby!
A year in the life of a grafted apple tree.
Following is a description of how I deal with my newly grafted trees. Feedback is welcomed.
I do my grafts and bundle each variety together and store them in damp sawdust out of the sun, out of the wind, out of the rain, ideally at 7-9°C (in a room in the barn). I use the plastic milk cartons/crates 13” x 13” x 10.5” high and put a black plastic bag inside the crate and inside the plastic bag I put my grafted trees upright in bundles packed with damp (not wet!) sawdust.
I tie the black plastic bag over the sawdust so the unions are covered, but the scions are not. This increases the humidity around the unions and also prevents the sawdust from drying out.
I’ve read that some people cover their unions for this first month. There is often not enough depth in the milk crates for the sawdust to cover the unions, but if you found a deeper container, it would be a good idea to cover the unions.
I don’t want them in the dark or the leaves will open up white (etiolated).
I’m in south coastal B.C. and I try to finish my grafting by the end of March.
Before the end of April, I pot the newly grafted dwarf trees into one-gallon pots (larger rootstocks into 2 gallon pots) in a commercially-prepared bark mulch/sawdust/peat mixture (West Creek Farms in Fort Langley) .
I have four raised beds about 12' x 4' x 16" high. These beds were originally made for vegetables and they are in a compound surrounded by deer fencing.
There are about ten raised beds and I have commandeered four of the beds for my grafts. The soil has been removed so my pots are on the ground surrounded by 16" walls. There is an automatic overhead sprinkling system and a layer of metal hardware cloth (1 cm x 1 cm holes) on the ground under the pots to keep the meadow mice (voles) out. The hardware cloth is attached to the sides and a tight hole has been cut for the irrigation risers so the voles cannot get in!!!!
The height of the beds seems to deter the rabbits. I've never had rabbit damage, but I don't leave the pots in the beds over winter (anthracnose canker loves cold wet bark) and rabbits usually do their damage in the winter.
I use slow-release fertilizer.
In 2009, I used 125 gms
Osmocote 14-14-14 (3-4 months) for every 10 x one-gallon pots (12.5 gms/pot)
and every 6 x 11L pots (20 gms/pot). 12.5 gms is 2.5 teaspoons per one gallon
pot. Twenty grams is 4 teaspoons per 11L pot..
This works out to 1.75 gm Nitrogen per one gallon pot and 2.9 gms per 11L pot.
I think I'll cut back even more in 2012.
It has been my experience that the root growth is better in pots than in the ground - more fibrous and more roots. In the ground they seem to produce one or two thicker roots and almost no fibrous roots.
In 2007, we had another well drilled so now I can use the automatic watering system for the whole of the summer.
For the last five years, we have had very hot dry summers, so I have put a lot of time into manually watering my nursery trees at least every two days and sometimes daily if it is very hot in July and August.
Bits and pieces: My MM106 and MM111 and M26 go into 11 L (2.5 gallon) pots and produce a very nice root system.
In September I start selling them.
Those that remain in mid-November are moved to my car-port. Here they are out of the rain and away from the rabbits.
In mid-February, I take them out of the carport and water them and start my selling season with Seedy Saturday at VanDusen Gardens. I cut the whips back to 27” from the soil level. The branches should form in the 6-8-10” below the cut. There should be no branches below about 18”. 30" would be a better height, but my truck canopy is 27" high and I transport my whips in the back of my pick-up truck with canopy in place.
By early May I am usually almost sold out. The remaining trees are 'potted up' into larger pots and go back into the raised beds, but with more space between them because in the second year they will put out branches.
If I have a grafted tree that I want to plant in my orchard, I have been waiting until they are two-years old. Meadow mice (voles) love the roots of one-year old apple trees. If they happen to run a tunnel next to a young apple tree they will eat absolutely every root and leave only a pointed stick where the roots were.
In November, 2005, I did plant about 15 one-year old trees, but I planted them in an open-bottomed cylinder of hardware cloth. The diameter of the cylinder is about 10”, the depth is about 10”. The holes are 1 cm x 1 cm. I plan to remove this cylinder of wire mesh in about November 2008 (I never did!). This has been well worthwhile. The roots of the nursery trees have not been eaten by the meadow voles. (In February, 2012, the wire mesh is still around the whips!).
My hope is that by having the mesh around the roots for three years, some roots will get big enough that the meadow mice won’t eat them. By removing the mesh in November, some small roots will be broken, but they should grow back quickly in the rainy months of November-December-January. Stay tuned to see how it works.
Friends have told me that 'bridging' should occur when the root grows through the 1 cm hole and then it grows thicker. The wire should become surrounded by root and after time, the wire will be embedded in the root. It may not be necessary to remove the wire mesh. I don't know.

Apple Varieties
for sale in February 2012.
My nursery opens each year in mid-February just in time for Seedy Saturday at
the VanDusen Gardens.
If there is a variety you would like, let me know. I can make almost anything if I can get scionwood. The ideal time to let me know is in January so I can find the appropriate scionwood. A good source of scionwood (and rootstocks) is the B C Fruit Testers Annual General Meeting in Saanich (March 17, 2012). See 'Events' on this web site.
If you would like me to send you this list, please email me.
The following is a chart
giving more information on all of these varieties. The information was taken
from Martin Crawford's Directory of Apple Cultivars (references)
February 4, 2012. I just cannot seem to copy and paste my 2012 list of apple
trees for sale to here on my website. I have left the old chart (2011) until
I can figure out what's happening.

Recommended List of Cider Apples
from my Langley, B.C., experience
by Derek Bisset phone: 604 888 7867
e-mail: 'derek_bisset' and the symbol for 'at' plus 'shaw.ca'
Yarlington Mill
Somerset vintage late mid season bittersweet cider apple.grown in modern bush
cider orchards.
Fruit medium-large , conical , yellow with dull red flush here in BC.
Blossom mid to late May (Day 15).
Tree has moderate vigour making a mid size tree on M26. Growth is spreading
with strong side branches which can easily overtake leader . Heavy crops every
year .
Relatively disease-free with no evidence of scab . Some resistance to canker.
Fruit drops in early to mid October but can hang later . Can be milled immediately
but stores into November
Juice is superior for cider with good sugar , mild tannin and earthy aroma for
those who like a very full, strong flavour.
Dabinett
Somerset vintage late bittersweet cider apple highly recommended for modern
bush orchards
Fruit medium but can be small, flattened round always coloured dark red .Regular
crops
Blossom mid to late May (Day 15 self-fertile).
Tree is a very weak grower and needs at least MM106 to make a moderate size
tree .Trees have spreading branches and leader can be lost .Potash fertilizing
recommended .
Disease free with some resistance to canker .
Fruit is late dropping mid to late October and stores well for milling later
in November .
Juice is excellent for cider , fruity with good aroma and pleasant , mild tannin.
Low acid needs to be blended with sharp juice for balanced cider. Cider is light,
soft,and with a fruity aroma .
Chisel Jersey
Somerset vintage late bittersweet cider apple grown extensively in modern orchards
.
Fruit is small to medium, conical with bright red colour . Heavy, regular crops.
Cracking and russetting reported in England not observed here .
Blossom mid to late May (Day 22).
Excellent tree form , mid size on M26 with upright growth making a neat christmas
tree shaped centre leader tree with very little pruning or shaping required.
Good for hedgerow .
Disease free with some resistance to canker .
Late fruit drops in late October, can hang later and stores very well for milling
in November.
Juice has a pleasant tannin and produces cider with a light floral aroma .
Other Varieties:
Muscadet de Dieppe is commonly available It produces
well for me although there are numerous reports of poor productivity.It blooms
early (Day 5). It makes good full, astringent cider although it has a couple
of drawbacks ; it is very biennial , alternating heavy crop with no crop at
all ; it is ready in August and doesn't store so that fermentation must take
place fast in warm conditions , not the best for good cider .
Michelin and Tremlett's Bitter are available and often
recommended as good producers . I have found disease to be a problem with both
. Michelin blooms Day 15 and produces very well but is a weak grower and has
been canker prone The juice is good for blending although not considered vintage
.Tremlett's Bitter blooms early (Day 5) and is reported by others to produce
well but without spraying develops severe scab to the point that all leaves
are lost midsummer and the tree weakens . The juice has a hard tannin suitable
for blending .
Stoke Red looks promising . It blooms late (Day 25).
It is a vigorous grower with large crops of small to medium fruit of vintage
quality .
Marechal blooms late (Day 25) and is turning out to be
a large, vigorous tree also with heavy crops and with fair resistance to disease.
Kingston Black blooms Day 15 and produces what is considered
the most valuable juice. It has a reputation as a canker-prone variety but avoided
disease for a surprising length of time
Brown's Apple (blooms Day 18) and Sweet
Coppin (blooms Day 15) so far have not grown well .
Foxwhelp as it appears locally has come to be called
Fauxwhelp as it bears no resemblance to the true English
variety which is a small, red, early apple. Fauxwhelp is early, but is large,
green-yellow with some red striping . One suggestion is that it is from an interstem
variety which got out of control and came to be propagated as Foxwhelp
Notes:
cider – is apple juice fermented somewhat in the
manner of a white wine. It can be made with any apple, but traditional cider
varieties give special qualities to the cider.
bitter - tannin in juice from these apples gives cider
with good colour and a fullness to taste not found in cider made from dessert
apples only.
bittersweet – has high sugar content as well as
high tannin. Most of the best cider apples are in this group but juice requires
blending with sharps to produce a balanced cider .
sharp – often cooking or crab apples are used to
blend and provide sharp flavour in cider since many of the best cider apples
lack acidity, Acidity gives cider a brisk, refreshing quality and helps with
preservation. It can be overpowering in new cider but reduces over time and
what was thought to be an unpleasant sour apple cider kept for two or three
years can improve remarkably.
bittersharp - relatively uncommon has bitterness and
acidity
hard/soft tannin – differentiates between qualities
of tannin in different apples . Dabinett has a full, soft pleasant tannin while
Tremblett's Bitter tannin is is harsh and has to be used carefully .
Early/mid/late – is used to refer to blossom, picking
and ripening dates .
biennial - older varieties of cider apple all tend to
become biennial bearing heavy crops one year and none the following. Unfortunately
this appears to be related to climate and all varieties with the tendency will
come into phase over time with the same on and off years. In most cases experiment
has shown that thinning does little to help. Modern varieties mentioned as being
suitable for bush orchards are chosen to avoid biennialism .
blossom - most cider apples blossom around mid-May in
the Lower Mainland
falling date - most cider apples unlike dessert apples
are not picked from the tree, but are allowed to fall or are shaken down and
picked from grass sward..To do this a date when most apples drop is useful.
ripening date – may not coincide with picking.
It is important to allow maximum sugar to develop before milling and late varieties
are stored until testing shows full ripeness.Dabinett may drop in October and
be kept several weeks into November before milling. Waiting may also be useful
to cool cider-making conditions since most cider makers want slow fermentations
.
tree size - results from a combination of rootstock effects
and vigour . Thus a weak grower like Dabinett produces a very small tree on
M26 and a moderate size tree on MM106 while Yarlington and Chisel Jersey produce
moderate size trees on M26 . Larger trees are recommended for cider apples since
the fruit tend to be numerous and smaller to be shaken down for picking They
require less pruning since size and appearance of fruit is less an issue compared
to dessert apples.
disease – canker is the main concern because of
tree losses. All the cider apple trees get canker and none have complete resistance
. However some trees like Michelin become cankered very quickly in our conditions
while Chisel Jersey and Dabinett appear to resist infection for longer . Yarlington
has avoided infection longest for me . Scab is less of a concern although I
have found I could not grow Tremblett's Bitter well because scab caused it to
lose leaves so badly it went into decline . Presumably spraying would correct
this although clean culture alone did not .
single variety – none of the cider apples used
alone produces a rounded, full cider. They are best in a blend which has juice
with tannin acid and sugar in balance as well as some apples chosen for aroma
.
blending - is required to produce a balanced cider with
suggested one third of each : cider apples for bitterness , crab or sharp cooking
for acid , and dessert for sweetness and aroma .
milling – apples varieties selected for cider have
milling qualities not found in dessert or dual purpose apples . Unlike most
apples which tend to mush to a puree when milled, these apples come out of the
mill as chips with almost a sawdust consistency . A puree is very hard to press
since there are no channels for the juice . Think of trying to press applesauce
. Cider apple pulp appears to be drier but actually produces more juice because
it runs more freely .
