While many gardeners assume rosemary and thyme thrive on neglect, these beloved Mediterranean herbs actually benefit from strategic feeding during their peak growing season. Contrary to popular belief, these aromatic plants need nutritional support to reach their full potential in British gardens.
The Hidden Hunger of Mediterranean Herbs
Rosemary and thyme have developed a reputation as low-maintenance plants that prefer poor soil, but this misconception could be holding back your herb garden's performance. During spring and summer, these plants enter their most active growth phase and require additional nutrients to produce the lush, fragrant foliage gardeners crave.
Choosing the Right Fertiliser
Not all plant foods are created equal when it comes to Mediterranean herbs. Experts recommend:
- Liquid fertilisers that provide quick nutrient absorption
- Balanced formulas with equal NPK ratios (nitrogen, phosphorus, potassium)
- Organic options like compost tea or seaweed extracts
- Slow-release granules for continuous feeding
Perfect Timing for Maximum Impact
The key to successful herb fertilisation lies in timing. Early spring, as new growth emerges, is the ideal moment to begin your feeding regimen. Continue with light applications every 4-6 weeks throughout the growing season, but cease feeding by late summer to allow plants to harden off before winter.
Application Techniques That Work
Proper application ensures your herbs receive the benefits without the risk of burning delicate roots:
- Water plants thoroughly before fertilising
- Apply diluted liquid fertiliser to moist soil
- Avoid direct contact with leaves and stems
- Follow package instructions for correct dosage
With this simple fertilising strategy, your rosemary and thyme will reward you with vigorous growth, intense aroma, and abundant harvests throughout the season.
