In my distant youth I thought I understood why (most) fruit trees were
grafted onto different root stock:-

The 'pure' fruit is difficult to grow from seed and isn't vigorous
enough to grow at a reasonable pace so bits of the original (Cox,
Bramley, whatever) are grafted onto a vigourously growing root
stock and off you go.


However I now believe this is somewhat simplistic and probably even
wrong. Among other things some rootstocks seem to be chosen to
inhibit the fruit tree so it doesn't grow too big as I understand it
now.

So, a couple of questions:-
Is it possible in general to grow fruit trees from seed or are
there other issues than vigour (or lack of vigour) that prevent
one doing this?

Does the same apply to all fruit trees (e.g. apples, pears,
cherries, plums, etc.) or is it only some types that are grafted
and others are 'complete' as it were.

What do the suckers on various fruit trees grow into if they are
left to grow? We get masses of suckers growing up from the roots
of our plum trees, often several yards away from the trees. Do
these grow into fruit bearing trees if separated and planted or do
they grow into the plum equivalent of a crab apple or some such?

We have an apple tree that I think grew from below the graft on a
tree that all but died. It's very vigorous! It's become quite a
sizeable tree in just a couple of years and bears a lot of fruit
already. Is it going to cause us any problems? (We have lots of
space - several acres altogether)

IIRC, Bramley is usually grown from cuttings, and only grafted if a
small tree is required.

However I now believe this is somewhat simplistic and probably even
wrong. Among other things some rootstocks seem to be chosen to
inhibit the fruit tree so it doesn't grow too big as I understand it
now.

Yes. They seldom produce anything like the fruit you got the pips from.
I planted the pips from a lemon two years ago. Two of the seedlings are
now four feet high, and have thorns; one is about a foot and has smaller
thorns; the rest vary from eighteen inches to six inches, and have no
thorns.

Does the same apply to all fruit trees (e.g. apples, pears,
cherries, plums, etc.) or is it only some types that are grafted
and others are 'complete' as it were.

Usually, scions are grafted on to a rootstock to dictate their mode of
growth. Many apple trees are far too vigorous and become rather large.

What do the suckers on various fruit trees grow into if they are
left to grow?

Rootstock.

We get masses of suckers growing up from the roots
of our plum trees, often several yards away from the trees. Do
these grow into fruit bearing trees if separated and planted or do
they grow into the plum equivalent of a crab apple or some such?

Depends what the rootstock was in the first place. there's no definitive
answer.

We have an apple tree that I think grew from below the graft on a
tree that all but died. It's very vigorous! It's become quite a
sizeable tree in just a couple of years and bears a lot of fruit
already. Is it going to cause us any problems? (We have lots of

No. You can always keep it pruned/trimmed if it tries to get out of
hand. If the fruit is worthwhile, I'd keep it.

Seed production is sexual reproduction - in other words, normally the
pollen comes from a different plant (I say 'normally' because some
plants - though not usually apples and pears - are self-fertile and will
pollinate themselves in preference to failing to set seed), and
therefore the 'child' grown from the seed will not necessarily look like
either of its parents.

Grafting is asexual reproduction, and so the resulting tree (at least
the grafted bit) is genetically identical to the tree that you cut the
piece for grafting from.

In theory it is possible to carry out asexual reproduction by cuttings,
but I think the success rate with grafts is higher.

But the main reason for grafting is, AFIAW, the one you state, of
restricting the growth to manageable size.

Does the same apply to all fruit trees (e.g. apples, pears,
cherries, plums, etc.) or is it only some types that are grafted
and others are 'complete' as it were.

I don't think mulberries are grafted.

Does anyone know if medlars are grafted - and on to what?

We have an apple tree that I think grew from below the graft on a
tree that all but died. It's very vigorous! It's become quite a
sizeable tree in just a couple of years and bears a lot of fruit

You may eventually need a ladder to pick the fruit ;-)

Of course! It's obvious isn't it, thanks!

Well some of our other trees are getting that way too so one more big
tree is hardly a problem.
