Monthly care calendar

Timings are for a temperate Northern Hemisphere climate. In warmer areas tasks start earlier, in colder areas later; in the Southern Hemisphere shift them by six months.

January
  • Watering: Not needed if rainfall is sufficient; in dry periods keep the soil slightly moist (5 L/m² per 15 days).
  • Pruning: Remove only leaves damaged in winter.
  • General care: Clear foreign leaves off it to prevent rotting.
  • Pests & diseases: In standing water it can develop root collar rot.
  • Frost risk: None; it is frost tolerant.
February
  • Watering: Not needed if rainfall is sufficient; in dry periods keep the soil slightly moist (5 L/m² per 15 days).
  • Pruning: Remove only leaves damaged in winter.
  • General care: Limit the edges to control its spread, and prepare for propagation.
  • Pests & diseases: Check drainage to prevent root collar rot.
  • Frost risk: None; it is frost tolerant.
March
  • Watering: In a way that preserves soil moisture (7-10 L/m² per week); reduce if there is rain.
  • Fertilizing: Slow-release balanced fertilizer (NPK 15-15-15), 20-30 g/m², do not overdo it.
  • Pruning: After flowering, cut the fading flower stalks.
  • Plant protection: Against aphids (neem oil).
  • General care: The best time to propagate by root division.
  • Pests & diseases: Check for powdery mildew and aphids.
April
  • Watering: If there is no rainfall, water every 15 days.
  • Fertilizing: If not applied at the start of the month, it can still be applied; do not overapply, and consult a specialist.
  • Pruning: When the flowers are over, tidy the plant by cutting the fading stalks.
  • Plant protection: Monitor for aphids and powdery mildew (sulfur).
  • General care: Keep the spreading shoots under control.
  • Pests & diseases: Watch out for root collar rot.
May
  • Watering: If there is no rainfall, water once a week.
  • Pruning: Regularly remove spent flowers at the base; this encourages new flowering.
  • Plant protection: Watch out for powdery mildew; ensure air circulation.
  • General care: Spread a 5-7 cm layer of mulch over the root zone; it retains soil moisture and suppresses weeds. Do not pile mulch against the trunk.
  • Pests & diseases: Avoid overwatering. It causes rot.
June
  • Watering: Water deeply twice a week; prefer infrequent and generous watering over small and frequent. Water so that the soil is wetted 10-15 cm down from the surface.
  • Fertilizing: Do not fertilize; fertilizing in the heat stresses the plant.
  • Pruning: Regularly remove spent flowers at the base; this encourages new flowering.
  • Plant protection: For spider mites (abamectin).
  • General care: A thin layer of mulch helps conserve moisture.
  • Pests & diseases: Check for leaf scorch (sun) and spider mites.
July
  • Watering: Water deeply twice a week; prefer infrequent and generous watering over small and frequent. Water so that the soil is wetted 10-15 cm down from the surface.
  • Pruning: Regularly remove spent flowers at the base; this encourages new flowering.
  • Plant protection: Watch for spider mites and root rot.
  • General care: Keep it in a position sheltered from midday sun; scorching at the leaf edges is a sign of burn.
  • Pests & diseases: Root collar rot is the biggest risk; ensure good drainage.
August
  • Watering: Water deeply twice a week; prefer infrequent and generous watering over small and frequent. Water so that the soil is wetted 10-15 cm down from the surface.
  • Pruning: Regularly remove spent flowers at the base; this encourages new flowering.
  • Plant protection: Continue checking for spider mites.
  • General care: Clear the shoots in areas where you do not want it to spread.
  • Pests & diseases: Watch for fungal diseases during extreme heat and humidity.
September
  • Watering: If there is no rainfall, water once a week.
  • Fertilizing: Not necessary. If the plant is weak, a potassium-dominant fertilizer (NPK 5-10-15) can be applied. Do not over-apply, and consult an agronomist.
  • Pruning: Regularly remove spent flowers at the base; this encourages new flowering.
  • Plant protection: Pest activity decreases; take action if necessary.
  • General care: The best time for planting new plants, dividing and relocating.
  • Pests & diseases: Check drainage to prevent root collar rot.
October
  • Watering: If there is no rainfall, water every 15 days.
  • Pruning: Carry out a general autumn clean-up.
  • General care: Last chance to propagate by root division. Control its spread.
  • Pests & diseases: Watch for slugs that may develop under fallen leaves.
November
  • Watering: Rainfall is generally sufficient; water 1-2 times a month if needed.
  • General care: You can mulch around the plant with dry leaves to prepare its roots for winter.
  • Pests & diseases: Keep the surface clean to guard against excess moisture and rot.
  • Frost risk: None; it is frost tolerant.
December
  • Watering: Rainfall is generally sufficient; water 1-2 times a month if needed.
