Oriental Plane Care

Platanus orientalis

A long-lived deciduous shade tree of monumental and cultural importance in Turkey. Although it likes deep, moist soil, it is quite drought tolerant. It is known for its mottled, flaking bark and broad shade; it is much more resistant to anthracnose than the American Sycamore.

Hardy · -20 °C / -4 °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: Main pruning time. Prune young trees to build structure, and prune older trees to remove dry, diseased or weak branches that pose a safety risk (usually requires a professional).
  • General care: Dormancy period.
February
  • Pruning: While dormant, remove dry, broken, crossing and inward-growing branches so that air and light reach the inside of the crown. It grows very large; leave at least 12-15 m distance from buildings, infrastructure and overhead lines. The hairy leaves and fruit dust can irritate the respiratory tract.
  • General care: Clear away pruning debris.
March
  • Watering: Water a newly planted specimen more often than established plants during its first year, as its root system is still shallow.
  • Fertilizing: Not needed. If the soil is very poor, compost or slow-release fertilizer can be given to young 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: 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).
  • Frost risk: Young shoots may be affected by severe late frosts.
April
  • Watering: If there is no rainfall, water every 15 days.
  • Plant protection: Check the undersides of the leaves for lace bugs (Corythucha ciliata).
  • General care: Flowering begins.
May
  • Watering: If there is no rainfall, water once a week.
  • 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: Flowering continues. Spread mulch 5-7 cm thick over the root zone; it conserves soil moisture and suppresses weeds. Do not pile mulch against the trunk.
  • 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.
  • General care: The trunk bark peels off, giving a decorative appearance.
  • Pests & diseases: Powdery mildew (Erysiphe platani) can form a white powdery coating on the leaves but is usually harmless.
July
  • 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.
  • General care: It provides deep shade during the hottest times.
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.
September
  • Watering: If there is no rainfall, water once a week.
  • General care: Growth slows.
  • Pests & diseases: Lace bug (Corythucha ciliata) damage may continue as a speckled appearance on the leaves, but it does not seriously harm the tree.
October
  • Watering: If there is no rainfall, water every 15 days.
  • 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: The leaves turn yellow and begin to fall. The fallen leaves can be collected and composted.
  • Pests & diseases: During humid and cool periods, monitor the leaves and trunk for signs of mold, spots and rot.
November
  • 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 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. Collect fallen leaves; many disease agents and pests overwinter under them.
  • Pests & diseases: During humid and cool periods, monitor the leaves and trunk for signs of mold, spots and rot.
December
  • Watering: Water a newly planted specimen more often than established plants during its first year, as its root system is still shallow.
  • Pruning: Once the tree is fully dormant, major pruning can begin toward the end of the month.
  • General care: Good time for planting and transplanting.
