Monterey Cypress Care

Cupressus macrocarpa

A fast-growing cypress adapted to the Mediterranean climate. It needs full sun and well-drained soil, but the extreme summer heat of Manisa can stress the tree and make it susceptible to cypress canker (Seiridium).

Half-hardy · -12 °C / 10 °F

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: If needed, this is a suitable period for structural pruning or hedge correction.
  • General care: Check drainage; water should not collect around the base of the tree.
  • Pests & diseases: Check for resin flow, dieback and bark discoloration on the branches for cypress 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.
February
  • Fertilizing: For young trees, a slow-release balanced NPK fertilizer can be applied at the end of the month (do not overapply).
  • Pruning: It does not need formative pruning and its top should not be cut. Only remove dry, broken, and diseased branches. Shape lightly only from the green zone; it does not shoot from brown wood. It is tolerant of sea wind.
  • Plant protection: If there is a history of scale insects, dormant oils can be used.
  • General care: Keep the area around the tree clean and airy.
  • Pests & diseases: Keep looking 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.
  • Fertilizing: If it was not given in February, give it at the start of this month.
  • Pruning: Avoid pruning in wet weather because of the risk of canker spores spreading.
  • 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: During humid and cool periods, monitor the leaves and trunk for signs of mold, spots and rot. Check the branches and trunk for brown, stationary bumps (scale insects).
April
  • Watering: If there is no rainfall, water every 15 days. Water newly planted plants more often than established plants during the first year; the root system is still shallow.
  • Pruning: Hedge pruning can be done, but disinfect tools after each plant.
  • Plant protection: If you see signs of cypress canker (branch dieback), cut the diseased branch 10-15 cm into healthy wood.
  • General care: Good time for planting and transplanting.
  • Pests & diseases: Dieback is the most important clue to canker.
May
  • Watering: If there is no rainfall, water once a week.
  • Pruning: Hedge pruning can continue.
  • 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: Check the branches and trunk for brown, fixed bumps (scale insects).
June
  • Watering: Water deeply twice a week; prefer infrequent and generous watering over small and frequent. The root zone should be wetted to a depth of 30-40 cm.
  • Pruning: Only light hedge trimming; do not cut large branches.

  • Fertilizing: Never given.
  • Plant protection: The spider mite population may increase (abamectin).
  • General care: Monitor the tree's overall health.
  • Pests & diseases: High temperatures increase disease and pest stress.
August
  • Watering: Water deeply twice a week; prefer infrequent and generous watering over small and frequent. The root zone should be wetted to a depth of 30-40 cm.

  • Pests & diseases: Do not overlook signs of spider mites and canker.
September
  • Watering: If there is no rainfall, water once a week.
