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 required; the plant is dormant and winter rains are sufficient.
  • Fertilizing: Absolutely do not fertilize.
  • General care: The biggest risk in winter is excessively wet soil, so excellent drainage is vital.
  • Pests & diseases: Care must be taken against root rot.
February
  • Pruning: Light pruning can be done to remove branches damaged in winter. Wait for the main pruning/harvest.
  • General care: The plant is preparing to wake up.
March
  • Watering: Usually not needed. Only if newly planted and the spring is very dry, water 1-2 times a month.
  • General care: New aromatic shoots appear.
April
  • Pruning: This is one of the best times to harvest. When the plant begins to flower or is in flower, cut its branches so that 10-15 cm remains above the ground.
  • General care: Flowering begins. The plant's essential oil content is at its highest during this period.
May
  • Pruning: The main harvest period continues. After flowering, you can lightly prune the plant so that it stays more compact.
  • General care: Dry the harvested branches in the shade.
  • Pests & diseases: Avoid watering to prevent root rot.
June
  • Watering: Not needed; it is fully adapted to summer drought.
  • Pruning: It can be done, but the flavor quality may not be as high as in spring.
  • General care: It can be propagated by semi-hardwood cuttings in early summer.
July
  • General care: The plant may be semi-dormant during the hottest part of summer; this is normal.

  • Pruning: Pruning is usually not required this month. The plant is tired from summer and should be left to rest.
  • Plant protection: Not required, its natural structure keeps pests away.

October
  • Watering: Not required; autumn rains are sufficient.
  • Pruning: Avoid pruning the plant too hard going into winter; this can increase frost damage.
