Why is the re-growth on my lillypilly hedge small even though I have fertilised
one hedge is in sandy soil the other in rich loamy soil both the one in sandy soil is thick at bottom and thinning at top and other has large holes in top with no sign of leaves growing any bigger despite watering and fertilizing since last year. No evidence of possums or pests
Now that it is spring and the weather is warming up, your lillypilly hedge would normally be putting on healthy new growth. It is difficult to understand why this is not happening, particularly as you have fertilised and haver kept your plants well watered. A plant thinning at the top does suggest that perhaps something is eating the new growth. You say that there is no evidence of possum or pest attack. Yates has a wonderful new product available - Yates Possum Repellent Spray helps protect your precious plants by deterring possums from browsing on sprayed plants.
Contains a special combination of ingredients that help reduce possums browsing on plants.
Lasts for up to 7 days or more with regular re-treatment.
Can be used on ornamental and edible plants and has only a 1 day withholding period.
The formulation was developed by Professor Lynne Selwood and is protected by a patent granted to the University of Melbourne.
You might also like to apply a Yates product called Yates Dynamic Lifter Liquid Concentrate to begin with, and then once your plant starts to put on new growth, then switch to Dynamic Lifter Soil Improver and Fertiliser which will promote further growth. If you notice any of the leaves are being eaten, it may be caterpillars that are the culprit. Using a product such as Yates Success Ultra, will control this pest.
