What goes wrong with Primula
| Problem | What you'll see | What to do |
|---|---|---|
| Aphids | Sticky residue and distorted leaves | Use insecticidal soap or neem oil |
| Slugs | Irregular holes in leaves | Apply iron phosphate slug bait |
| Slugs and snails | Holes through the leaf rosette and flower stems severed at the base overnight | Clear damp hiding places and use traps or barriers from the moment growth starts |
