Invasive raspberries
 

My raspberry canes are in the border of the garden and are starting to
send suckers out into the very small "lawn". I've got a similar problem
with blackberries. I'm happy to zap the brambles with weed-killer, but
if I do the same with the raspberries is this going to affect the main
canes? What's the best way to deal with the volunteers if not
glyphosate?

Glyphosate is a systemic herbicide which is translocated into the roots.
So, yes, it would affect the main canes. Glyphosate is particularly
effective on grasses, so it would dispose of the lawn faster than the
canes.

Mowing will deal with the volunteers.

Raspberry runners are shallow-rooted, so a physical barrier, such as
lawn-edging will prevent recurrence.

If you use that weedkiller you will kill the roots and as they are all
connected you will lose the lot. Dig up the ones you don't want and bury a
barrier along the row to stop them invading again.

Why not just mow them? The individual canes won't get big enough to be
a problem in between lawn mowings.

That's what I thought.

They're in the lawn, so digging is less of an option. The buried barrier
is, though. How deep would it need to go?

Ahahaha. Well, if it would stay dry long enough for OldBloke to get out
and do some mowing, that would be an option, I reckon. In the meantime,
it's pointy bits on bare feet!

Well, with the soles of my feet being what they are, I would just
tread them underfoot :-)

Mowing will stop them if they actually come up in the lawn, if in the border
you need to dig them out as you would any weed spreading by root.

Raspberry runners are shallow-rooted,

WHAT?

I've given up on several after I've dug down two feet :-(

Possibly it depends on variety, but the ones that are spreading across
my allotment (I'm going to dig some out and give them to my
cousin-in-law come autumn) form new plants via roots that run maybe an
inch under the surface. The roots beneath the canes are deeper, but I
don't have two feet of top soil for them to grow in, and I don't recall
them going down more than a foot.

I do and they did, when I had them. I dug them out 1' down, and they
still came back. Only weakly, unlike bindweed.

Mine come up strongly and repeatedly, often in the veg. plots where it's
difficult to dig during the growing season :-(

I trust youall have noticed that I'm making a distinction between
runners and other roots. It's the runners that the OP would be worrying
about.

In the case of raspberries runners are specialised structures involved
in vegetative reproduction. They grow parallel to the surface of the
ground, and produce roots and shoots at points among their length. I
suspect that technically they may be rhizomes, which are technically
underground stems, not roots. Compare the runners of strawberries (which
being aboveground, are technically stolons.)

Roots are feeding and anchoring organs, sometimes pressed into service
as storage organs (as are many other parts of plants).

The yellow-fruited autumn-bearing variety that I have sends up new
shoots several feet away from the canes. I also have a red-fruited,
summer-bearing variety which is less aggressive.
