Questions On Lilly Pillies

13 years ago

Hi there,

I am looking for a large hedge to screen my neighbour, whose block is approximately 2.5 metres above mine (and separated by a retaining wall). The aim is to get to a height of 4+ metres. I live 70km south of Sydney, on the coast.

I would like further information on the following four types of Lilly-Pillies (as the information of the web is rather confusing):

Ã¯Â¿Â½ Acmena Smithii

Ã¯Â¿Â½ Acmena Smithii Ã¯Â¿Â½MinorÃ¯Â¿Â½

Ã¯Â¿Â½ Syzygium Austral Ã¯Â¿Â½ResilienceÃ¯Â¿Â½

Ã¯Â¿Â½ Syzygium Luehmannii

My questions are as follows:

(1) Are all of the above resistant to psyllids?

(2) What is the expected height of each of these varieties?

(3) How fast does each variety grow? (or you can list the order of fastest growth to slowest growth)

(4) How far apart should the plants be?

Many thanks for your help!

Best wishes,

Stefania

As a rule all Acemna are psyllid free but only some of the Syzygiums, and most of the Austral varieties are affected although A. Resilience - resilient to psyllid - should be ok and is good to 3 or 4 metres so I've been told. Acmena Smithii is a spreading tree to around 5 metres perhaps a bit more. I am unfamiliar with A.S. Minor. Syz. Luehmannii is generally psyllid free and good for around 4 metres, maybe a bit more. You could also consider Photinea 'Red Robin', I have 3 of them in blocking the neighbours and they are around 6 metres plus after about 6 years. It is disease free, dense to about 3 metres wide with attractive reddish foliage. Hope that's of assistance.

Sheryl, how close to the tree do you want to plant your veges? Lilly Pilly trees generally don't have very invasive root systems. (In fact, they are recommended for planting around swimming pools). Having said that, ANY large tree will draw nutrients from the surrounding soil, including your vege beds if they are close by. Try asking your question on this related GW forum... (And g'day, Pat! Whaddya mean not many Aussies here?) Regards, Shax Here is a link that might be useful: Aussie Native Plants

Pruning Lilly Pilly Trees

I have a line of Lilly Pilly's along my side fence planted about 10 years back to create some privacy from next door. They are probably over 10-12 metres high now but the bottom 2 metres are bare of leaves. My question is "If I cut along the line say 4 or 5 metres high will leaves start to grow under and fill up the 2 meters gap at the bottom and also grow high again"?

It's rather a narrow planting area but if they've been going OK for all these years, that would rule out a lot of things. And there are enough past years where weather extremes have probably been experienced. Barring some sort of accidental poisoning.... something in the nature of a defoliant, or something used on the driveway that's washed in, I can only think, as you did, that the burial in chip mulch set them back. Maybe the chips leached something of sap into the soil, or generated too much heat buildup, or simply smothered surface roots. I can't suggest anything other than TLC and a bit of fertilizer to see if you can get them going again. I don't know enough about pruning to comment further.

Help! What is doing this to my lilly pilly's?
Q

I'm sorry I really can't tell what's happening with those patches on the leaves. Salt build-up? insect eggs? My first suggestion is to take all the pics and some leaf samples back to where you bought the plants, and see what they can suggest. It may just be transplant shock. Maybe the location of the tubs is more exposed than where they were kept, and they are struggling to harden off. I can't really tell what the material of the planters is... if concrete there'd be some possible leaching? Maybe just the narrow pots and exposure is too hot? Could be over or under watering, too much fertilizing, probs with the potting mix. suggest you take some samples of all, including the potting mix brand, back for help from the providers.
