What's eating my invicta gooseberry?
Gooseberry sawfly (Nematus ribesii)
Signs: Pale green caterpillars with black spots eat leaves from the centre of the bush outward, leaving bare stems.
Control: Inspect undersides of leaves in spring; hand-pick early; spray pyrethrin or bifenazate if larvae are numerous.
Gooseberry aphid (Aphis grossulariae)
Signs: Tips of new shoots curl and crinkle; colonies distort young growth and stunt development.
Control: Pinch out infested shoot tips; apply insecticidal soap or neem oil spray.
Birds and squirrels
Signs: Green or ripe fruits taken before harvest; branches sometimes broken by squirrels.
Control: Net with fine-mesh fruit netting as fruits size up; cage the bush if squirrel pressure is high.
