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
  • 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 -10 °C.
February
  • Pruning: When the risk of frost has passed, remove dead, broken, rubbing and inward-growing branches that crowd the canopy, using clean tools. Do not reduce the canopy heavily in a single year. Skip if: frost is expected in the coming days, the tree is under severe water stress, or the cut would involve large main branches.
  • 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 -10 °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: Apply a balanced fertilizer or well-rotted organic fertilizer once when it wakes from dormancy. Because yield and fruit quality depend on nutrient balance, having a soil analysis done is especially useful for this plant.
  • Pruning: When the risk of frost has passed, remove dead, broken, rubbing and inward-growing branches that crowd the canopy, using clean tools. Do not reduce the canopy heavily in a single year. Skip if: frost is expected in the coming days, the tree is under severe water stress, or the cut would involve large main branches.
  • 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 branches and trunk for brown, fixed bumps (scale insects). During humid, cool periods, watch leaves and trunk for mold, spots and rot.
April

  • Pruning: When the risk of frost has passed, remove dead, broken, rubbing and inward-growing branches that crowd the canopy, using clean tools. Do not reduce the canopy heavily in a single year. Skip if: frost is expected in the coming days, the tree is under severe water stress, or the cut would involve large main branches.
  • General care: Suitable period for planting and transplanting. Flowering begins.
May
  • Watering: Check the latest rainfall, soil moisture, and the plant's flowering/fruit development status. Do not water an established tree frequently like a lawn; if watering is needed, plan an application that soaks the root zone deeply. Skip if: the soil is still moist, there has been effective rainfall, or the root zone is regularly wetted by lawn irrigation.
  • 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. Drainage is vital for this plant. In heavy soil that holds water, plant it on a raised mound or berm 20-30 cm high, so the root collar stays above the surrounding soil level.
  • Pests & diseases: Check the branches and trunk for brown, fixed bumps (scale insects).
June
  • Watering: Check the latest rainfall, soil moisture, and the plant's flowering/fruit development status. Do not water an established tree frequently like a lawn; if watering is needed, plan an application that soaks the root zone deeply. Skip if: the soil is still moist, there has been effective rainfall, or the root zone is regularly wetted by lawn irrigation.
July
  • Watering: Check the latest rainfall, soil moisture, and the plant's flowering/fruit development status. Do not water an established tree frequently like a lawn; if watering is needed, plan an application that soaks the root zone deeply. Skip if: the soil is still moist, there has been effective rainfall, or the root zone is regularly wetted by lawn irrigation.
August
  • Watering: Check the latest rainfall, soil moisture, and the plant's flowering/fruit development status. Do not water an established tree frequently like a lawn; if watering is needed, plan an application that soaks the root zone deeply. Skip if: the soil is still moist, there has been effective rainfall, or the root zone is regularly wetted by lawn irrigation.
September

October
  • 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.
  • 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: Suitable period for planting and transplanting. Make sure water does not pool in the root zone during winter rains; for this plant, drainage is more critical than irrigation.
  • Pests & diseases: During humid and cool periods, monitor the leaves and trunk for signs of mold, spots and rot.
December
  • General care: Evergreen leaves continue to lose water in winter. Water thoroughly once before the soil freezes.
  • 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 -10 °C.
