Can my Lilly Pilly hedge be saved?

7 years ago

last modified: 7 years ago

As these devastating pictures show, the poor hedge is really struggling. Can anything be done?

I can't be certain, but they seemed to go particularly downhill when we had a fallen tree chipped and all the chips were piled on the garden bed, covering up the bases of the trunks by a good 10-20cm. I could be drawing a false correlation though.

Where in australia are you? Which direction are they facing? How old are they if you planted them or if not any estimates if they came with the property? What's on the other side of the fence? Is it your yard or someone else's? Are the areas level or is one higher than the other? Are they the lp's growing above the fenceline (cos it looks very dense) or are those trees on the other side coming over and if so what are they?

sorry for the 20 questions, but let's get a "picture" of the whole problem

Pests on my Lilly Pilly trees

Cara About the best I can suggest is repotting them into some fresh mix. If you get rain in autumn, now would be a good time to do this. I bought a Syzygium last year and repotted promptly as it was very pot-bound. I used a bonsai-type mix- very free-draining with 5mm grit, but with some added humus as I know they like a rich soil that holds moisture. If your mix has been drying out too quickly because the roots have filled the pot, or it lacks humus, then your plants won't be able to repel 'invaders'. Don't take too much of the root ball back. Leave about a third and take out the older brown roots, leaving the young white growing tips as much as possible. When you've done it, put it on either the south or east side of the house and keep it just moist for about a month. Dunk it about once a week, wait until the bubbles stop, and let it drain, not stand in water. After the first month has passed from when you repotted, you might want to give it a monthly liquid fertiliser feed. Miracle Gro has been pretty good for my plants. If they make growth over winter, check again in spring to see if the roots have colonised the pot. If they have, and you've got good top growth, too, pot on without disturbing either top or roots. If it's really booming - do another check next autumn. I've got a Coprosma that's only about 15cm high but grows furiously so it needs repotting twice a year. I'm not sure how fast your lilly pillies will grow, but keeping an eye on root growth is a prudent thing to do to keep pests away. And thorough watering.

Hi Aggie, This is likely to upset some people, but I havent seen a native LP which has fruit comparable to the exotic varieties for size. Syzygium Jambos and Jambolana both have large fruit, but the mention of these species elicits howls of protest from many of the regulars. Cheers, Artie

Gosh, it seems there's huge ecological restoration needed in your neighbourhood, blckrose. You've certainly described an environmental disaster zone of monumentous proportions. All of those factors you mention have had enormous negative impacts on native wildlife thereby causing many people to reach for the sprays because natural controls are no longer present. As you would be aware, Noisy Miners have proliferated because of the massive clearance of native understorey thereby creating their preferred open woodland conditions. You might also be aware that a number of communities are now conducting Indian Mynah eradication programmes in order to encourage the return of native woodland birds, many species of which are threatened but provide wonderful environmental services such as control of insect pests if given the chance. Cat controls are also slowly gathering pace but, of course, much more is needed if we are to have a cat-free, native wildlife restoration culture in Australia. So if we are to reduce the impact & cost of sprays in our environment then the issue needs to be tackled on a very broad, multi-pronged front, as you are perhaps implying, blckrose.

If you're looking for a lilly-pilly/ syzygium of no more than medium height, you couldn't go past Acmena smithii minor 'cherry surprise', which is a particularly lovely one to 2 to 3 metres. It's an attractive deep green in colour, with pink to red tips. Another lovely one, though perhaps not as hardy, is Acmena variegata, which grows to 3 metres. Nice, natural shape, dense in leaf. There' also a number of syzygiums worth considering, just make sure they are psysilid resistant. In fact there is one on the market named 'Resilence'. Worth a try. B

I'm in Sydney.

The plants are facing East (as in, the fence is running N-S)

No idea on age - they were well established (and healthy) when I moved in 6 years ago.

It's my side of the property (hence the fence) and the plants extend to about 20 cm above the fence line which slopes down consistently to the street. This is the level I've kept it trimmed at.

There is only 1 tree of note and it's not interfering at all with the hedge.

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.
