AmandaHost

And we've got no one on the line at the moment, so now is a great time.

A

AmandaHost

8:31

In the meantime, Judy, you want to talk about hydrangeas? Yeah,

Judy SharpeGuest

8:34

we were last week, remember, Amanda, but then we ran out of time, unfortunately.

Judy SharpeGuest

8:39

And so I wanted to talk about today about how to fertilise hydrangeas.

Judy SharpeGuest

8:45

So the secret is when you prune them back, if they're white or greenish, you can't change their colour.

A

AmandaHost

8:56

You can't change their colour? No.

A

AmandaHost

8:57

I didn't know they changed colour.

A

AmandaHost

8:58

I don't understand.

A

AmandaHost

8:59

They

Judy SharpeGuest

8:59

change.

Judy SharpeGuest

9:00

Hydrangeas change according to the... alkaline or the acid.

Judy SharpeGuest

9:05

Oh.

Judy SharpeGuest

9:05

Yeah.

Judy SharpeGuest

9:06

So, okay, I better give the advice out here.

Judy SharpeGuest

9:09

So if you want them to be blue, you use cow manure.

Judy SharpeGuest

9:15

Right.

Judy SharpeGuest

9:16

And that's acid, you see.

Judy SharpeGuest

9:17

Yep.

Judy SharpeGuest

9:18

And if you want them to be pink, you use poultry manure.

Judy SharpeGuest

9:23

And that's a base? Yeah.

Judy SharpeGuest

9:24

Right.

Judy SharpeGuest

9:25

Yeah, so it's very simple.

Judy SharpeGuest

9:26

If you want pink, you use poultry manure.

Judy SharpeGuest

9:30

If you want blue, you use cow manure.

Judy SharpeGuest

9:32

But if you've got white or green, forget it.
