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
  • Pruning: To preserve its natural form, it is generally not pruned; only dry or diseased branches are removed.
  • General care: Make sure drainage is good.
  • Pests & diseases: Check the branches for resin flow and dieback for cypress canker (Seiridium).
  • Frost risk: In hard and prolonged frosts, cover the root zone with mulch or dry leaves; also protect young plants. It is damaged below about -12 °C.
February
  • Fertilizing: Not required, it is adapted to poor soils.
  • Pruning: It does not need formative pruning and its top should not be cut. Only remove dry, broken, and diseased branches. It is naturally columnar in form; it needs no pruning. Only remove dead or damaged leader shoots together with their extensions. Two main leader shoots should not be removed at the same time; the symmetry is spoiled.
  • General care: Keep the area around the tree clean.
  • Pests & diseases: Check for signs of canker.
  • Frost risk: In hard and prolonged frosts, cover the root zone with mulch or dry leaves; also protect young plants. It is damaged below about -12 °C.
March
  • Watering: Water a newly planted specimen more often than established plants during its first year, as its root system is still shallow.
  • Pruning: Avoid pruning in wet weather.
  • Plant protection: If symptoms spread and treatment is needed, consult a licensed plant-protection supplier or an agronomist. Plant protection products are regulated; follow local rules.
  • General care: Good time for planting and transplanting.
  • Pests & diseases: Check the branches and trunk for brown, fixed bumps (scale insects).
April
  • Watering: Water a newly planted specimen more often than established plants during its first year, as its root system is still shallow.
  • Plant protection: If you see signs of cypress canker (branch dieback), cut the diseased branch 10-15 cm into healthy wood and disinfect your tools.
  • General care: Good time for planting and transplanting.
  • Pests & diseases: Dieback is the most important sign of disease.
May
  • Watering: For young saplings, 30-40 L per week; not needed for mature trees.
  • Plant protection: If symptoms spread and treatment is needed, consult a licensed plant-protection supplier or an agronomist. Plant protection products are regulated; follow local rules.
  • General care: Drainage is vital for this plant. In heavy, water-retaining soil, plant on a mound or bed raised 20-30 cm, and keep the root collar above the surrounding soil level.
  • Pests & diseases: Check the branches and trunk for brown, fixed bumps (scale insects).
June
  • Watering: In a long drought, water deeply once a month.
  • General care: Enjoy the tree's drought tolerance.
  • Pests & diseases: Spider mites may appear along dusty roadsides.
July

  • Plant protection: If symptoms spread and treatment is needed, consult a licensed plant-protection supplier or an agronomist. Plant protection products are regulated; follow local rules.
  • Pests & diseases: In hot and dry weather, look on the undersides of the leaves for fine webbing and speckled yellowing (spider mites). Washing the leaves during the cool hours reduces their numbers.
