Possum Wars

1. Net affected plants with shade cloth or white bird netting at night time. Quick, cheap, and darn effective! This is absolutely the best way to protect young plants and seedlings from possum attack. Why not supplement this with a hanging cat scare face or two? Available from nurseries, these scare faces look like cats and have reflective eyes, pretty scary if you are a possum!

2. Sprinkling blood and bone fertiliser around the base of ornamental plants and fruit trees can act as a significant possum deterrent. They hate the smell, and will be less inclined to munch on treated plants!

3. A home made garlic spray of 2 tablespoons of crushed garlic in one litre of hot water, left to stand over night, strained and sprayed onto foliage, fruits and tasty growing tips is an old favourite of mine, and it seems to work. Subsequently, try chillies or Indonesian fish sauce. Just remember to wash your produce before eating!

4. A spray made from Quassia chips (chips of bark from a South American tree).Add 100 g chips to 2 litres water and heat for one hour before straining. Add one tablespoon detergent. Dilute at rate of 1 part of solution to four parts water and apply as a spray. Quassia chips are available at many nurseries, and are pretty affective, forming the base ingredient of many commercially available possum repellents (e.g.: Poss-Off).

5. My grandmothers’ personal favourite, and one she swears by, is the tea-based deterrent. Boil two litres of water; add 4 heaped teaspoons of Lapsang Souchong tea and leave to cool. Strain of liquid and apply from a plastic spray bottle directly onto affected plants. Reapply every two weeks and always after rain. Make a fresh brew every time.

6. Wack a bit of undiluted Tabasco sauce on affected plants……a sure solution unless your possum likes it hot!

7. A watered down solution of a little detergent and some English mustard sprayed directly onto the foliage and fruits of tasty plants.

8. Commercially available possum deterrents such as Poss-Off or Scat, work by emitting an unpleasant odour, so, when used according to the instructions on the products, claim to deter the little blighters!
