Growing Guide
Rose Cultivation
Roses are hungry, deep-rooting shrubs. Their reputation for being difficult stems from poor cultivar selection and timid pruning.
Pruning Physiology
Pruning stimulates apical dominance in lower dormant buds. Hard pruning results in fewer, larger blooms; light pruning results in more, smaller blooms. Cut to an outward-facing bud to maintain an open centre.
Common Mistakes
- Replant disease: planting a new rose exactly where an old one died without exchanging the soil.
- Ignoring hygiene: leaving black-spotted leaves on the soil surface over winter.

FAQ
How do I stop black spot?
You cannot cure it once present. Prevent by choosing resistant cultivars, clearing fallen leaves, and maintaining plant vigor through proper feeding and watering.
