50 Year Old Juniper - Diseased? was created by tom_747

Posted 4 years 2 months ago #63673
Greetings from Munich Germany

I have a 50 year old Juniper that is being cared for under strict instructions by my parents in Melbourne, Australia.

I'm really worried about the reduced growth and dual colouring (yellow needles) in particular. I'm not enough of an expert to know if this is a bad sign so really keen to hear from the experts here?

Some points:

- Age, about 50 years old
- Repotted about 12 months ago
- Pruned about 18 months ago
- In full sun position, probably gets direct sunlight 75% of the day
- Currently mid Spring in Australia

All tips welcome

Danke / Cheers
Tom

Hi and welcome.
What kind of juniper is it?
Not a Shimpaku, Itoigawa or Kishu, I guess.
Needle (prickly) foliage, not scale foliage, and this tendency to grow upwards...
Almost like a Larch.
But the first thought is: could be lack of proper watering.
Then some junipers like cold winters, I don't know if this one is getting sad about the heat in Australia.
And if the Spring over there is anything as hot as our spring here in Brazil, it will need at least daily waterings.

Hi Clicio

Thanks for the reply.

It's a Foemina Juniper, it does have prickly leaves but over the past couple of years it has had some scale growth.

Spring hasn't been too warm in Melbourne, it's just starting to heat up now. I have been given very strict instructions to keep the soil watered just after its dried up, I don't think watering is the issue. It seems to have been in decline the past 18 or so months. See attached photo just before a prune, photo is about 2 years old.

I did transfer the tree to a pot with about double the volume, potentially could be related?

Cheers Tom

Do your parents water the whole pot, or just "give it sips"?

Watering means a good drenching.
And maybe waiting till after it dries is too tricky.

To be honest, Melbourne is a hot place. I would not be concerned too much about overwatering (But the substrate is high in organics).
