Herb Care Guide: Lemongrass, Ruda and Rosemary in Florida

Simple steps for thriving herbs in your garden or patio

Herbs are some of the easiest and most rewarding plants to grow—whether you’re working with a backyard garden or a few pots on your porch. In this guide, we’ll cover how to care for three popular herbs we grow right here at Inca Plant Nursery: lemongrass, ruda (rue), and rosemary.

Each herb brings something special: lemongrass adds tropical aroma, ruda is steeped in tradition, and rosemary brings flavor and resilience. Let’s dig in!

Lemongrass (Cymbopogon citratus)

Light:

  • Full sun is best – at least 6–8 hours/day
  • Grows well in hot, humid Florida weather

Soil & Water:

  • Needs well-draining soil; sandy loam works great
  • Water 2–3 times/week during dry spells
  • Don’t let it stay soggy—avoid waterlogged pots

Maintenance:

  • Trim old leaves regularly to keep it tidy
  • Harvest by cutting stalks at the base
  • Divide large clumps every year or two to refresh growth

Tips:

  • Grows great in large containers
  • Attracts beneficial insects like ladybugs
  • Excellent in teas, soups, and Thai dishes

Ruda / Rue (Ruta graveolens)

Ruda is a traditional medicinal herb in many cultures, known for its strong scent and pest-repelling properties.

Light:

  • Prefers full sun, tolerates partial shade

Soil & Water:

  • Likes dry to medium soil—don’t overwater
  • Water once or twice a week; let soil dry between waterings
  • Avoid heavy clay or soggy soil

Maintenance:

  • Prune regularly to keep it bushy
  • Remove flower stalks if you want to promote more leafy growth
  • Wear gloves—it can irritate sensitive skin

Tips:

  • Deer-resistant and pest-repelling
  • Use with caution—ruda can be toxic in large amounts
  • Often planted for spiritual and protective uses

Rosemary (Rosmarinus officinalis)

This hardy herb is a kitchen staple and landscape star thanks to its fragrance and drought-tolerance.

Light:

  • Full sun is a must – 6+ hours/day
  • Thrives in Florida heat when given airflow

Soil & Water:

  • Needs well-drained, slightly sandy soil
  • Water once a week or when top inch is dry
  • Avoid overwatering—root rot is the biggest threat

Maintenance:

  • Prune lightly throughout the year to keep shape
  • Harvest sprigs often—this encourages fresh growth
  • Protect from humidity build-up with good spacing

Tips:

  • Great for containers, borders, and rock gardens
  • Bees love the flowers
  • Dry sprigs easily for pantry use

General Herb Care Tips for Florida

  • Morning sun is ideal – helps dry dew and prevent fungal issues
  • Use terra cotta pots for herbs prone to overwatering (like rosemary and ruda)
  • Fertilize lightly with compost or organic herb food
  • Mulch with straw or bark to conserve moisture (but keep away from the base)
