Aphids

Plant chives and garlic to repel aphids. If an infestation occurs, spray the plant leaves with a mixture of soap and water. Try an insecticidal soap or mix biodegradable dish soap with a small amount of oil and water. Apply to the whole plant – don’t forget the underside of the leaves where the aphids frequently hang out! This will need to be repeated to kill off aphids and their offspring. Remember: you will need to re-apply after it rains!

Earwigs

Trap earwigs in a hollow tube. Earwigs will congregate in the tube overnight. Clean out the trap in the morning.

White flies

Try using an insecticidal soap or mineral oil for white flies. You will need to re-apply, just as with the aphids above.

Mites

Try using an insecticidal soap, mineral oil or sulphur.

Spider mites and mealy bugs

Remove insects such as spider mites and mealy bugs from your plants by blasting them with water from the hose.

Black Spot

Try 1 tablespoon baking soda and 2 tablespoons horticultural oil in 4 litres of water. Spray your roses every week to 10 days.

Mildew

Try garlic oil to combat a powdery mildew.

Fungus

Try borax, garlic, fungicidal soap or a sulphur-based fungicide.
