GRAFTING APPLE AND PEAR TREES
As the world moves on into an age of high technology, change
and progress are happening at all levels. There is no excuse now not to buy an
apple tree as I don’t have a big garden. Breeders and scientists have produced
trees to suit both commercial orchards as well as the enthusiastic gardener
with small gardens. The step over apple
tree grafted onto a dwarfing rootstock grows only a few feet tall but is kept
small with summer pruning. Another dwarf tree is the single stemmed Starline
apple (Firedance is a great variety) kept narrow and columnar also by summer
pruning all side shoots to a couple of buds. Other apples for small gardens
come as cordons, espaliers, fans or dwarf bushes all grown on dwarfing
rootstocks.

However you still have to sort out a good variety that is
disease resistant, easy to grow and has good flavour, but to complicate matters
you want an early variety to start picking ripe fruit at the end of August, continue
for a few more months on the tree then in store for a few more months.
Cutting a scion for grafting |
Over the years I have grown many varieties so now I can pick
from end of August with those in storage taking me through winter. My first
apple of the season started with the heritage variety the Oslin also known as
the Arbroath Pippin, then my early Discovery takes over for a few more weeks. Maincrop
Red Devil, and Red Falstaff keep me in apples into winter then finally it was
the end of February before my last Fiesta reached the plate though the cooker
Bramley lasted till March.
My garden my be bigger than your average, and I have four
trees, but to get my wide range of varieties one large tree is a family
Scion inserted into prepared branch |
My pear tree has undergone the same treatment and now has
Comice, Conference, The Christie, Beurre Hardy and soon Concorde will be added
to it.
In my early youth I was shown how to graft while working at
the Scottish Crop Research Institute which had a museum collection of apples
from all over the world to try and find varieties suited to Scottish conditions
so grafting was a common practise. It sounded very technical and difficult, but
is surprisingly easy and it is a wonderful feeling when you check up in early
summer and find all the grafts
Grafted shoot tied and sealed with grafting wax |
Today the technique is shown on many Youtube videos, and you
do not need many tools other than a very sharp knife, a pair of loppers or a saw
and a wee tub of wound sealer or grafting wax which can be applied cold.
In winter I collect strong one year old shoots of a good variety which I want to add onto my tree and heel them into a shaded cool spot in the garden. In spring once trees begin to grow the sap starts rising and acts like a lubricant helping the bark to separate from the stem to allow our graft to be easily inserted and the sap will bring the two together. The tree is prepared by selecting a branch to be grafted and cutting it down to allow space for a new shoot to grow. If this branch cut is about one inch across it will take one graft, but if you are doing a larger branch say four inches across it will take three grafts. Take the graftwood (also known as scions) and clean any soil from it. Now make a two inch long cut going right through the stem near the bottom of the shoot

Grafts begin to grow |
Paul Barnett from Sussex has grafted over 250 varieties on
one tree over the last 24 years.
Check over pots,
tubs and hanging baskets planted last autumn with spring flowering pansies and
primroses and replace any that have died in winter. There are now plenty in
flower available now in most garden centres.
