FionaAUDIENCE
3:36
was wondering why it would be so thorny compared to any other rose I've got.
3:42
Look, Fiona, I think it's how they're bred originally.
3:47
It's in the breeding, yes.
3:48
So, look, I don't know that particular rose to comment on it, but you're still getting flowers and it's happy, so.
3:56
I haven't got any flowers as yet, but it's got some buds coming up.
3:59
Okay, well, just watch you don't prick your fingers.
4:02
No, I know.

AlanAUDIENCE
16:51
Oh,
MarkHOST
11:42
Oh, there's your problem right there.
11:43
Yeah, and I did a bit of research and they're indicative only to clivias.
11:48
They are clivia grubs.
11:50
So, of course, I was a bit anxious yesterday because guess what? clivias are starting to flower.
11:57
A little bit early, but I think that's the sudden warm weather we're getting.
12:00
So I went out and I thought, oh no.
12:03
So I went right through the whole garden and I've got a few up and down the paths and that And I thought, if there's any of those grubs on this, I've got to get out.

18:05
Will I be able to put vegetables after that?
DebbieAUDIENCE
6:37
Yeah, that's probably the main thing that I've used, dynamic lifter sometimes.
6:42
Right.
6:42
Okay, Debbie, can I give you my recipe? Absolutely.
6:46
Okay.
6:47
Now, they're in the ground, aren't they? Yes.
6:49
And they're in the sun? Yes.
6:52
Well, what you need to do now, and it's a good time to do it now, coming up to spring, you go out under the drip line.

16 MINS LATER

MarkHOST
22:33
That makes sense.
AmandaHOST
19:32
And I keep
19:33
hammering that home, but I know that everyone doesn't listen every time.
19:37
So, you know, they might tune in one day and not hear it, and then another day.
19:42
That's right.
19:43
Yeah, how's that? That's good.
19:45
Okay.
19:45
Okay, so spring is here tomorrow.
AmandaHOST
22:51
Was I? Stop
PeterAUDIENCE
18:31
It's got flowers at the moment.
18:32
moment.But it's got these, like the swellings on the stems, look like bark swellings.
18:39
Right, okay.
18:40
Look, I'm pretty sure you've got galler, Peter.
18:42
Mm-hmm.
18:43
And you probably need to inject it, uh, to get rid of them.
18:47
'Cause someone said you scrape it or something.
speaker_9AUDIENCE
20:03
Yeah, well, w- it gets watered every second day.
AmandaHOST
0:58
Would I
0:58
like to talk about natives? Yes, thank you, Amanda, because here we are at the university in native city, I always call it.
1:05
It's so beautiful out here at the moment.
1:07
All the grevilleas are coming into flower.
1:10
It's worth, you know, just a walk around here at the moment.
1:13
Absolutely beautiful.
1:15
So the grevilleas are coming into flower and the native wattles are, which there are, of course, a lot here at the uni.

9 MINS LATER

EleanorAUDIENCE
10:26
Yeah, no, you are.
AmandaHOST
9:41
Sure you can
9:42
We got sidetracked then with that one.
9:44
But, um, I was going to talk about susaq- sasanqua camellias, and they need to be trimmed back and fertilized now with a little bit of cow manure.
9:54
And after you have the cow manure on, you then apply peat moss over the root surface
AmandaHOST
10:06
Now citrus
10:07
Now citrus.
10:08
Okey-dokey.
10:09
Potted citrus.
AmandaHOST
7:34
Now, Judy, you want to talk about the products that we were talking about
7:38
last week? Yes.
7:39
Well, of course, I thought we should because last week we had several gentlemen ring in about products that could be sprayed on the weeds that they use, that they get from, what do we call them, bulk supply stores, bulk supply stores.
7:57
And, you know, I think the couple of gentlemen that rang in might have been, you know, might have had a big garden or might have even been farmers, you know.
8:05
But one of them was called Grazon and the other one was called Javelin.
8:10
But then we had someone ring in about Grazon towards the end of the program.
8:15
I don't think we got them to air, did
AmandaHOST
8:18
They
AmandaHOST
7:41
Would you like to tell us about it?
7:42
Yes, certainly.
7:43
And he is a lovely gentleman, David Phillips.
7:47
And his wife is... having some work done in hospital and she wanted the azaleas repotted while she wasn't there or treated.
7:56
So he's asked a few questions and I've got some answers for you, David.
8:01
I hope you're listening today.
8:03
I would not do the cutting until the flowering is finished.

14 MINS LATER

AmandaHOST
22:24
Judy, you wanted to talk about your butcher boy.
AmandaHOST
0:30
Okay.
0:31
And he rang about his avocado at Birmingham Gardens.
0:35
Uh, and he's got a Reed, R-O-O-E-D, an eight-year-old Reed avocado, and he helps the fruit set by putting a sprinkler under the tree, mist for two hours.
AmandaHOST
1:45
[laughs]
1:45
Not at all.
1:46
So, uh, you know, I've, I just had a look and see what is the best ones for the coastal area, and the Fuerte is the best one.
1:54
And it ripens from April to for several months.
2:00
So a lot of a- avocados, uh, but this gentleman was talking about another variety that I didn't know, so he might ring in today and, and tell us some effort.
AmandaHOST
10:58
What's a grafted plant? Can you explain that for me, please? Sure,
11:00
darling.
11:02
You know, they do graft on certain stock.
11:05
So, you know, they have a good, how can I describe it? So lemons are all grafted.
11:13
All the citrus are grafted.
11:15
So they're grafted on what you call trifoliata stock, the citrus.
11:20
I'm not sure what avocados are grafted on.

10 MINS LATER

AmandaHOST
21:33
Now, Judy, you had some other things you wanted to talk about as well today.
AmandaHOST
0:10
Well, you know, we don't want you to be sick, but we're glad you're better.
0:13
Thank you very much.
0:14
Well, at the weekend, some news about my roses.
0:18
Oh, yes.
0:19
Okay.
0:19
My standards were pruned.
0:22
I don't know, the other listeners out there with roses are going to say, that's a bit early, but we've had so much rain, Amanda, as you know, and so much cold, I normally wait until July to do the roses.

20 MINS LATER

speaker_2AUDIENCE
20:40
look, I've
AmandaHOST
14:35
Okay.
14:36
Yeah, good time to do it leading up to spring.
14:39
And, uh, other things we've got problems with at the moment are gardenias and Murrayas.
14:44
A lady rang in a bit earlier about them, but um, uh, they're developing yellow growth, and that can happen during the winter because, uh, you know, they're just, they're a little bit hungry.
14:57
So we need to spray them with chelated iron over the root system and dig in cow manure-

7 MINS LATER

AmandaHOST
21:56
So now just lastly, Judy, you wanna talk about roses?
21:59
Yeah, just briefly.
22:01
Roses are becoming dormant now.
