Rosemary ‘Tuscan Blue’ Care — Watering, Pruning & Feeding Tips
Rosemary ‘Tuscan Blue’ is a hardy Mediterranean variety celebrated for its upright growth and vivid blue flowers. Its care revolves around three essentials — full sunlight, well-drained soil, and minimal watering. This CompleteGrow guide explains exactly how to keep your Tuscan Blue rosemary dense, aromatic, and disease-free.Core Growing Requirements
- Sunlight: At least 6–8 hours of full sun per day.
- Soil: Sandy or loamy mix with fast drainage; avoid heavy clay.
- Watering: Deep soak only when top 5 cm of soil is dry — rosemary hates “wet feet.”
- Temperature: Thrives in 15–30 °C; protect from severe frost.
- Feeding: Light but consistent — see Section 3 for CompleteGrow’s feeding plan.


Watering, Pruning, and Seasonal Care
Watering Schedule
Water deeply every 7–10 days in warm months. Reduce to every 2–3 weeks in winter. Always water early morning to allow foliage to dry quickly. In pots, ensure excellent drainage holes and elevate containers off cold surfaces.
Pruning & Shaping
- Prune after flowering (late spring) to encourage branching and control height.
- Trim new soft growth by one-third; avoid cutting into old, woody stems.
- Lightly shape throughout summer to maintain form and airflow.
- Harvest sprigs frequently — regular trimming strengthens plant structure.
Seasonal Care Tips
Summer: Maintain shape and water moderately.
Autumn: Stop feeding six weeks before winter; remove any diseased wood.
Winter: Protect from frost; keep soil just barely moist.


Feeding & Common Questions
Fertiliser Routine
Apply CompleteGrow All Purpose Liquid NPK 20-20-20 every 3–4 weeks from early spring to late autumn. Use 5 mL per 2 L of water, soaking soil evenly. The balanced ratio supports consistent growth and richer foliage without causing leggy stems.
Soil Refresh & Maintenance
- Repot container plants every two years to refresh the mix.
- Mix in coarse sand or perlite to enhance aeration.
- Top-dress with a handful of dolomitic lime annually to maintain slight alkalinity.
FAQs — Rosemary ‘Tuscan Blue’ Care
How do I keep rosemary from getting woody?
Regular light pruning after flowering encourages soft new shoots and prevents hard wood formation.
Why are my rosemary leaves turning brown?
Usually from excess moisture or poor drainage — allow soil to dry before watering again.
Does Tuscan Blue need fertiliser often?
Only moderately — monthly feeding with CompleteGrow 20-20-20 is sufficient for healthy colour and aroma.
CompleteGrow Recommendation
For vibrant, upright rosemary, use CompleteGrow All Purpose Liquid NPK 20-20-20 every few weeks. It provides steady nitrogen and potassium to strengthen stems, enhance essential oils, and extend blooming.
