What is

Grafting ?Grafting ?

It can be difficult for farmers to earn their livelihoodsfrom growing only grain crops. That’s why it’s good to learnnew methods which increase production to farm our ownland. One method is by making a nursery to grow improvedfruit tree seedlings. This means you can grow tasty and nutri-tious fruit on your own land, and at the same time sell or tradeextra production to earn cash. There are many methods ofjoining local wild fruit tree rootstock to high producing im-proved varieties. One of those methods, which is detailed inthis chapter, is called grafting.

Grafting is a method of joining the cutting (scion) of animproved variety of fruit tree onto the root (rootstock) of alocal compatible variety.

Why do Grafting ? to doGrafting ?

2 3

• Grafted trees produce fruit quicker. A tree grown from seedmay take 8-10 years to fruit, but agrafted tree will only take 2-4 years.

• A tree grown from seed may producepoor tasting fruit. Grafting is done toimprove the taste and size of the fruit.

• A tree grown from seed may notproduce fruit the same as the treethe seed came from (mother tree).But a grafted tree will be just asgood as the tree the cutting (scion)came from.

• A grafted tree will continue to givethe same quality fruit for many years.

• Grafted fruit trees can be sold togive an income to the household.

• By producing your own seedlingsand fruit, you save money.

• Seedlings can be produced locally,saving time in searching for theright fruit trees to plant.

Benefits of Grafting

How does grafting work ?All plants have tiny channels which take water and nu-

trients up to the leaves and down again. These channels areinside the bark but outside the woody part of the stem. Theyform a greenish band around the stem called the cambium.

In a successful graft, the channelsin the cambium carrying nutrientsand water from the rootstock to thescion and back are continuous, not

broken.

Grafting Method

Preparing the rootstock for grafting

• A local, wild fruit tree seedling grownin the nursery or naturally in the forestis called the rootstock.

• For grafting, the rootstock is ideally thethickness of a pencil, but it can be alittle thinner or thicker than this (5-10mm).

• Leaves and branches should be pre-vented from growing from the rootstockon the first 4-6 inches from the ground.These can be carefully pinched off fromtime to time.

Selecting the scion for grafting• To graft onto a local, wild rootstock, the branch cutting

from a good fruiting tree is needed.• This branch cutting is called a scion.• The scion sould be from a healthy, disease-free tree that

gives good fruit.• A one year old branch should be used as scion wood.• If the scion is to be brought from far away, a whole branch

should be cut. The cut end should be covered with mossand packed in sacking. Any buds should be unbroken, andthe cutting should not be exposed to the sun.

Cutting the scion

• There should be 3-5 live buds on thescion, which should be cut at a slant,just above the top bud.

Cutting the rootstock andgrafting the scion

• The way to prepare rootstock is described inthe Fruit Nursery chapter.

• On the day before grafting, water the root-stock well and mulch thickly.

• Using a sharp knife or similar tool, make a 1inch long slanting cut through the rootstock1-3 inches from the ground. The face of thecut should be completely flat.

Preparedrootstock

• Trim the scion so it has 3-5 buds. The scion should not bethicker than the rootstock.

• The scion should be the same diameter as the rootstock ifpossible. It can be thinner than the rootstock, but not thicker.

• Make a 1 inch long slanting cut atthe base of the scion, the samelength as the cut on the root-stock. The face of the cutshould be completely flat.

• Half way up the slantingcuts of both rootsock andscion cut a small nick intothe face of the cut edge (see also p.10, photo5 to 8).

• Join rootstock and scion together by insertingthe nicks on opposing faces of the rootstockand scion into each other.

• Push rootstock and scion together so that thecambium layers are in close contact at leaston one side of the join (if rootstock is largerthan scion), if not both sides (if rootstock andscion are the same size).

• The scion and rootstock should be held to-gether by the opposing nicks beinginterlinked with each other.

How tomaintain

a grafted seedling

14 15

Care needed after grafting

• The grafted seedlings need fencingagainst livestock, and should not betouched.

• They should be protected fromstrong sun, wind, hail, and heavyrain. Make a 50cm high thatchto place over them, and thenursery should be in a shelteredsite.

• The seedlings need regularwatering to keep the soil moist.

• After 4 months, when the scionhas sprouted well, the plasticcan be carefully removed.

Withoutprotection,

work iswasted

PinchingAny leaves or branches sprouting below the graft (from

the rootstock) should be pinched off with the fingers, other-wise they take valuable water and nutrients meant for abovethe graft. This is called pinching.

If the graft is unsuccessful, a single sprout from therootstock can be allowed to grow. This can be used to graftanother scion again next year.

Farmers'ExperienceFarmers'Experience

From Jajarkot district, Dhime -7, Dharnasi village in Nepal, MrShanta Bahadur Pun has doneplenty of grafting. Now let'sread about his experiences.

Shanta Bahadur Pun

After I learned grafting Ipracticed at home with a smalllocal, wild peach nursery. Ontothem I grafted improved peach,plum, apricot and almond. On such a small piece of land thisgave such a high production, and you can literally eat thefruits of this success within 3 years! In the spring, shades overthe beds are very important - this stops the hot sun from dry-ing out the newly grafted seedlings. Water needs to be givencarefully, at ground level. If you water from above, water canget inside and ruin the graft, and it can also shake the seed-lings and so break the graft. The cutting tools need to be sharpand clean - like in any operation. I’ve succeeded using justthe local ashi (hook), I don’t need a posh grafting knife. Atfirst the other farmers didn’t believe that it would work. Igrafted plants on my own farm, and sold them. Then theybelieved me. Nowadays all the farmers have small or largenurseries on their land.
