Speaker 1 (00:06):
You're listening to the Resident Builder podcast with Peter Wolfcamp
from News Talks.

Speaker 2 (00:11):
A b.

Speaker 3 (00:19):
Righty.

Speaker 4 (00:19):
Oh well, it's with great pleasure that I could say, Hey, Red,
welcome back to the show.

Speaker 3 (00:25):
He's back on, back on.

Speaker 4 (00:27):
Sounding great, sounding great.

Speaker 5 (00:29):
Thank you, thank you, good to be back.

Speaker 3 (00:32):
Recovery is condition work.

Speaker 5 (00:34):
It is going oriagonably well.

Speaker 3 (00:36):
It is pain and need pain and the knee.

Speaker 5 (00:42):
Oh god, good form here and slowly.

Speaker 3 (00:46):
And slowly getting better. I'm starting to do a little
bit of work to dad, and you know, I'm doing
gentle stuff. That's good. Awesome.

Speaker 5 (00:53):
Judy Genie will tell me what to do.

Speaker 3 (00:55):
She goes, this needs doing.

Speaker 5 (00:56):
Yeah, yeah, I know this needs and yes, I know.

Speaker 3 (01:00):
All right.

Speaker 4 (01:00):
Well, I'm delighted that you're up and about. So that's
awesome because we've got a bunch of texts to get
through and a whole bunch of callers as well. Actually,
let's start with the plum tree question. Someone's Textal, I
have two older plum trees about five to six meters
high that i'd like to prone write down. How much
of a percentage would you allow before sort of you know,

(01:23):
over shocking the tree? And is now a good time
from Carl.

Speaker 3 (01:28):
The best time is late summer, so you are a
bit on the late side, I think. But if you
are really going to do big stuff, I would suggest
you can go to I have you and I talked
about something like a third you know, off the tree
at a time, and then do it again next year,
And as you and I once discussed, do it into

(01:49):
a particular part first a third, and then go next
year to that other part of the tree. Third, and
then the last third. You do that on the third year,
and you'll find that it's probably the least destructive way
of not doing the plum.

Speaker 4 (02:05):
Tree excellent because I mean, at five or six meters high,
you're never going to get up there to get the plums.
That's just feeding the birds, isn't it.

Speaker 3 (02:12):
And it also depends on the size off your you're
climbing to it things.

Speaker 4 (02:16):
You know, Yeah, yeah, sure, absolutely right. We've got some
polls Alistair. Good morning to you.

Speaker 6 (02:23):
Morn le heads.

Speaker 3 (02:24):
Have things goody good, thank you, that's good.

Speaker 6 (02:28):
Just a question. I've got a neighbor that's got some
really nice old school roses which I'm hender take some
propagation from and grow. Now I know the best time
to cut them is at nighttime so you can't see me.
But what time of the year is the best time
to grow it?

Speaker 4 (02:45):
After your own hat.

Speaker 3 (02:46):
There was a decade from left field. I love that.
That's good.

Speaker 5 (02:51):
Have you talked to.

Speaker 6 (02:54):
Occasionally? Yes, But I'm more the roses thanything else.

Speaker 3 (02:58):
Yeah, yeah, I get that. So so you want to
do it at night, I suppose.

Speaker 6 (03:04):
Well, I can county any time, but it's more the
time of year that's the best.

Speaker 3 (03:08):
Okay, Well you can, and you've taken cutting, so you're
basically doing the doing the pruning.

Speaker 6 (03:16):
Just some cutting, so I can propagate the roses for myself.

Speaker 3 (03:19):
I think why not? Why not try it a little
bit later after winter, and you'll find that depth the
time when they get a bit more interested in reproduction
and becoming bigger. It's starting to get into the root
zones and all that sort of stuff. That's one of
the ways to go. Yeah, I think it's good, nat.
I won't do it now. It's a bit too cult.

Speaker 6 (03:41):
Here, too cold, and any trucks on making the actual
job workers. Anything you've got to do to make it,
cuttings are going to work better.

Speaker 3 (03:49):
You get some of that stuff you put on the
on the on the way where the place where you've
cut it, and that would then make more what you
call it things coming at the bottom so that the
root zone will be really told, get on with it
now in springtime. So yeah, yeah, hormone stuff there you go.

(04:11):
There's all sorts of hormones like that, and the ones
for the roast are usually the best. Yeah. Absolutely, Okay,
after wonder go go well, thanks very much all.

Speaker 4 (04:21):
Of this to you, Alistair, thank you very much for that.
And Roger a very good morning to you. Hello, Roger.

Speaker 3 (04:32):
Might be he might be getting some cuttings from his name.

Speaker 4 (04:36):
Uh now, someone that's sticks through gardening doesn't help to
soak the seeds, I guess before propagating.

Speaker 3 (04:46):
Which so which glance is he talking about?

Speaker 4 (04:49):
I'm not sure they haven't been specific. So as a
general rule, is it something that helps kind of break
the husk around the outside of the seed. Does it
help or does it just put it in the ground.

Speaker 3 (05:01):
Which some species deff works. Actually, it's quite nice. I
just got to be note from Julie saying, actually, if
you go late late's for doing that thing with the roses.
If you do it late winter, you can start doing
it already, so you don't even have to wait that long. Okay,
he says, she's probably she I think she's cut Ben

(05:23):
and he said, right, yeah, Julie said better better digs
with late winter.

Speaker 4 (05:29):
Roses. Okay, all right, so we're definitely into the well,
we're definitely into winter now, well not quite officially.

Speaker 3 (05:36):
No, No, it's actually not too bad to you. We
had a lovely summer's day almost again with twenty degrees
twenty one degree, yes, very nice.

Speaker 4 (05:46):
Right, let's try Roger again. Hello, Roger.

Speaker 7 (05:48):
Hello, I'll just cut it burter powers down right down,
and I won't give her a stamp.

Speaker 3 (05:57):
Sorry, what plant are you talking about? Roger?

Speaker 7 (05:59):
Thirty paradies a better paradise. Yeah, because it's light month
foot part brought up and standards. Now the oven, you
want to get rid of it because hole pathway, we
go out the other pathway and that's and standards and

(06:20):
ovens lift it up.

Speaker 3 (06:22):
So I just I just want to get this right.
You want to get rid of the bird of Paradise?

Speaker 7 (06:27):
Yeah, because it's it's it's my pathway and it's stuck
a lap and it's danderous.

Speaker 3 (06:35):
Can you dig under the root zone.

Speaker 7 (06:37):
I've not got the root, I can.

Speaker 3 (06:40):
Okay, And I think that is probably at this stage
the best thing you can do and see if it
will come back in springtime, and if it does, you
keep going with that, you know, to start to start
just checking all sorts of pesticides in there. I am
not sure if that's good for the plants nearby.

Speaker 7 (06:59):
No, no plant is that's just no plants they bar
just a purpad or someone elsewhere.

Speaker 3 (07:05):
Mm hmm.

Speaker 7 (07:06):
I think it lest the ground next to it, because.

Speaker 4 (07:09):
I'm wondering a route whether if the you know, like
it's a sort of flexy type material, if you got
in there and sort of hacked away at it with
an axe, you'd get most of it out and then
treat the ground to stop anything re sprouting. That that
would probably do most of it. It's like those yukas
trying to get rid of yuka roots.

Speaker 3 (07:28):
The thing is they can be real big buggers. Yeah,
things can be yeah, so, but so it's a measure
of keeping going and have a nice sharp spade in
the way.

Speaker 4 (07:35):
You got much preciative body.

Speaker 3 (07:39):
Yeah, and you've got so much better in terms of
not not killing out things.

Speaker 4 (07:44):
Yeah, sure, absolutely. Now we can take your calls, oh,
eight hundred and eighty ten eighty couple of texts as well,
Hey rude, how would you get rid of wasps nest
in a cavity of a roof?

Speaker 3 (07:54):
Please?

Speaker 2 (07:56):
Ah?

Speaker 3 (07:58):
Okay, It depends a little bit on what wasps they are.
But if you've got if you've got paper wasps or
common wasps, the best thing is to wait till night.
If they go into the hold and you know where
it is, you make sure that you're going, You're going
to wait for it to get dark. You then use
some some material that kills them literally as they're inside,

(08:22):
but you do it in such a way that you
do it quickly into that hole spreads them and the
way you go and you get out. And if that,
if that doesn't work, then I wouldn't know what would
work unless you get somebody who does this as a job, right,
people that do all this stuff with these pests. Best
control way to go, and you use any of those

(08:44):
if you like anti insect stuff, chuck it into the
check it into the entrance. They will not like you.
And remember if somebody holds a court torch for you
at night.

Speaker 4 (08:54):
Yeah, yeah, I have to say it would seem that
I've had reasonable success with the ants nest that or
the bostniss that had developed.

Speaker 3 (09:04):
Question.

Speaker 4 (09:05):
So it was like a little crack tile on a
hip on a concrete tile roof. You could see them
coming in and out quite busy. Got up there foolishly
with some spray cands, and that just made them angry.
But then I went and got it's like a powder.
It's wasp and powder from I think I got it

(09:25):
from mine to ten. Went back and squirted that into
the opening and around the opening. And when I was
back there again the other day, I didn't see any
activity out of there. So if it's a DIY thing,
you can just use this little bottle of powder and
poke that in the air.

Speaker 3 (09:42):
Puffet not surprised. And the reason for that is that
said they no was powder all with their men called
the stuff. I know what you mean that when they
come flying in with their little wind beats, they will
disturb The powder goes everywhere, and it's a little bit
like you stop stopping the stuff everywhere when you're when
you're using some really big material and things that smack

(10:05):
into causing all sorts of powder to go everywhere. They
do not like that.

Speaker 4 (10:10):
It's like me coming inside after I've been in the
workshop and I'm covered in dust, and then magically there's
dust all through the house. I don't know how that happens.

Speaker 3 (10:17):
Yeah, you know, And I'll tell you what I can tell.
I can tell one person who would actually say something about.

Speaker 4 (10:23):
That, right, pretty much is angry. Okay, we're going to
take a short break. If you'd like to talk with
Rudi's back with us this morning, which is fantastic. Give
us a call right now on eight hundred and eighty
ten eighty. This is what you might call pent up demand.

(10:47):
So I've got a full board of calls and we're
going to be really super. People have missed you, mate,
People have missed you.

Speaker 3 (10:54):
Oh, thank you?

Speaker 4 (10:55):
Right, Oh Mike, good morning, Good morning.

Speaker 8 (11:00):
I would I've just brought a new house and it
has a ginger between two walls. It's very narrow, It's
only about a foot and a half gap, and this
ginger is like two and a half meters tall, and
I need to get rid of it. I can't even
you know, reach up to snap it off. I can't

(11:22):
get a metic or a tool up there to hack
it out. What's the best chemical I can use to
kill the ginger completely so it doesn't come back again.

Speaker 3 (11:35):
Oh gosha, golly, ginger control right there are Oh gosha, golly.
I'm actually thinking about this. I cannot come up with
this right now. You know what I should do. I
am going to Mike. I'm going to look at this
when we're off air, and next week I'll give you

(11:56):
the answer to what's the best ginger control in this case?
Because it's that stuff is between It's not easy to reach,
isn't it. I'm so was that it's not easy to reach,
is it?

Speaker 8 (12:10):
I can't reach it. It's between two walls, and it's
on quite a steep in climb between my neighbors.

Speaker 3 (12:16):
Doors, and you can't get to the root side. They
can't you.

Speaker 8 (12:20):
Oh no way. I mean that's what I need to do.
I know if I could reach it, I would dig
them out, you know.

Speaker 3 (12:26):
Yeah, but there are some pesticides you putchues. But I
just want to make sure that we can get something
that you can get down in that narrow space to
get into the base of the plants. Leave it with me, please,
I'll check it into my system for next week and
we'll put we'll talk about on the radio next week,
was there.

Speaker 4 (12:45):
Make sure we do that. Thank you, Mike and Marco.
Good morning to you.

Speaker 2 (12:51):
Hello there, Rude, two years ago. Hello, it's Marco. Three
years ago. I bought two. I bought three pejoratories from
other ten and they were different brands. Tell me to
buy different ones. They're all together, and one of them
has lots of fruit and two of them don't have any.

(13:13):
And I don't know why. Tell me about males and
females and what possible fertilizer or I should try.

Speaker 3 (13:22):
I don't think there's anything with males and females with
these things. So the fact that you do three different
fijoas means that you will have the different fruits that
they prepare or make at a slightly different time of
the year, so it becomes a much longer harvesting season,
if you like. Does it make sense like that? And

(13:42):
maybe a three years old now and they haven't done any.

Speaker 2 (13:46):
One of them. Only one of them has ever had
good fruit.

Speaker 3 (13:50):
All right, here's the next question, Marco, what are your
fertilize them with?

Speaker 4 (13:54):
Nothing?

Speaker 2 (13:55):
Just a bit of order?

Speaker 3 (13:57):
Ah question? How many times do you have breakfast in
the weekend or or in your life. These are important things.

Speaker 2 (14:07):
How many plants?

Speaker 3 (14:09):
Now, how many breakfasts do you have in your life?
On a let's say a monthly basis thirty one? There
you go. Oh, that's well, that's correct.

Speaker 2 (14:21):
Every day I love.

Speaker 3 (14:24):
But you know where I'm going through here, aren't you.
So you're going to get a fertilizer that you're going
to be used quite regularly from spring till say, late summer.
And you're going to use fertilizer that is high in
pot ash. So that's NPK, a high k in this case.

Speaker 5 (14:43):
So you use a fertilizer that is usually made.

Speaker 3 (14:46):
For fruiting plants or fruiting trees, and that, my friend,
will give all three species if you like, a chance
to become really fruiting.

Speaker 4 (14:56):
Yeah, oh great, it's all about feeding, I think at
the stage. Thank you very much for that, Mirco, much
appreciate it. And Karen, let's talk about wasps.

Speaker 9 (15:06):
Yeah. I've got an old seventies house that's got sort
of skirting on the bottom, and I've got a whole
lot of wasps that have all of a sudden decided
to go between the skirtings and go under the house.
And I can't PenPoint where they're going to in order
to sort of get someone and to power or anything.

(15:28):
Please give me any suggestions.

Speaker 3 (15:30):
Please. Yes, there are people that do WASP control in houses,
under houses and below houses, above houses and under houses.
And the treat is indeed what you're writing that way,
which you're talking about, is that gets really hard to
tell from the outside of the building where they actually go.
That's number one, so that is well seen. Number two,

(15:51):
you need some really good overalls and some.

Speaker 5 (15:53):
Really good material that allows you to go under the
house without getting done by them. So that means you
need to right stuff. And so what I'm coming to
know is the third thing, get somebody who knows how
to do this. Please not under percent sure how to
do it, and you haven't got the gear, don't go there.

Speaker 3 (16:13):
So go into the what I call the yellow pages,
you know what I mean, for a wasp and see
what we can find that that's these sort of things
for you.

Speaker 9 (16:21):
Honestly, be safe, because my other concern is, because those
skirtings go right around the house, would they just not
come through another way to the other side of the house.

Speaker 3 (16:33):
There might but that particular person that you can ask
to do this knows quite logically and quite well where
to stop the holes, how to stop them from getting
in and loosen place, et cetera, et cetera. It depends
entirely how these creatures are coming in. You might also
find that God's he or she has done the job
for you that most of the want to say, God,

(16:54):
it smells here, this is not good. And I do
I smell that that wasps here not a nice place
to live.

Speaker 9 (17:01):
Okay, thank you, thank you appreciate that.

Speaker 4 (17:04):
I think what one else?

Speaker 8 (17:05):
You're right?

Speaker 4 (17:06):
Go for the professionals. A couple of people have texted
and going, oh, look, if you're looking for WASP, make
sure you keep an eye on the hornets as well.
That's been you know, that's a very Awkland sort of issue.
But it's interesting that the exclusion zone or the zone
doesn't seem to have increased recently.

Speaker 3 (17:24):
I'm very hopeful here.

Speaker 4 (17:26):
Right, Okay, I'll try and get a bit more information
about that next.

Speaker 3 (17:31):
Well, last week in the in the newspaper, they i
think FBI said they were really really pleased with the
way it's going, and their fingers crossed they might actually
win the game. Wow, that was so good.
