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, natural rainfall is sufficient.
  • Pruning: Only hazardous branches broken in storms are removed; no main pruning is done.
  • General care: Flowering begins.
  • Pests & diseases: Check the trunk bark.
  • 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 -7 °C.
February
  • Watering: Not required, natural rainfall is sufficient.
  • Pruning: Pruning is not done before flowering.
  • General care: Flowering continues.
  • Pests & diseases: Continue observing.
  • 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 -7 °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: Not necessary (usually does not need it, as it fixes nitrogen).
  • Pruning: Do not prune while flowering continues.
  • Plant protection: If aphids are seen on the flowers, spray with a strong jet of water.
  • General care: Suitable period for planting and transplanting. Flowering continues.
  • Pests & diseases: Watch out for aphids on fresh shoots.
April
  • Watering: Water a newly planted specimen more often than established plants during its first year, as its root system is still shallow.
  • Pruning: Prune as soon as flowering ends. Next year's flower buds form over the summer; late pruning reduces flowering. After flowering is complete, do light shaping. Encourage a single trunk on young trees. Branches damaged by frost are cut back to living wood.
  • 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: Look for aphids (green or black clusters of small insects) on fresh shoot tips. If there are only a few, you can knock them off with a strong jet of water.
May
  • Watering: Water a newly planted specimen more often than established plants during its first year, as its root system is still shallow.
  • Pruning: The main pruning period has passed; only minor corrections can be made.
  • 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. Drainage is critical for this plant. In heavy, water-retaining soil, plant on a mound or bed raised 20-30 cm; the root collar should remain above the surrounding soil level.
  • Pests & diseases: If you see black spots with yellow halos on the leaves (black spot), collect the diseased leaves and remove them from the garden; the disease overwinters in fallen leaves. Check the fresh shoot tips for aphids (small clusters of green or black insects). If there are few, you can knock them off with a strong spray of water.
June
  • Watering: In a long drought, water deeply once a month.
  • Pruning: Do not prune at all this month.
  • 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: Applying mulch over the root zone retains soil moisture and prevents weeds.
  • Pests & diseases: If you see black spots with yellow halos on the leaves (black spot), collect the diseased leaves and remove them from the garden; the disease overwinters in fallen leaves. Check the fresh shoot tips for aphids (small clusters of green or black insects). If there are few, you can knock them off with a strong spray of water.
July
  • Watering: In midsummer, deep watering every 15-20 days is enough. Established plants (over 2 years old) do not need watering in most years. The root zone should be wetted to a depth of 30-40 cm.
  • Plant protection: In hot and dry weather, check for signs of spider mites (fine webs, yellowing on leaves) and spray if you see pests.
  • General care: Plants may become stressed during extreme heat; this is normal.
August
  • Watering: In midsummer, deep watering every 15-20 days is enough. Established plants (over 2 years old) do not need watering in most years. The root zone should be wetted to a depth of 30-40 cm.
  • General care: Monitor the tree's overall health and stability.
  • Pests & diseases: Check for scale insects.
September
  • Watering: In a long drought, water deeply once a month.
  • 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: A suitable month for planting new seedlings. You can prepare the soil.
  • Pests & diseases: If you see black spots with yellow halos on the leaves (black spot), collect the diseased leaves and remove them from the garden; the disease overwinters in fallen leaves.
October
  • Watering: Usually not needed, as rains begin.
  • Pruning: Remove only dry and broken branches.
  • General care: This is one of the best times for planting. Water generously after planting.
  • Pests & diseases: Against the risk of root rot, make sure drainage is good.
November
  • Pruning: Only broken branches that pose a danger are removed.
  • General care: In winter rains, make sure water does not pool in the root zone; for this plant, drainage is more critical than irrigation.
December
  • Pruning: Only broken branches that pose a danger are removed.
  • 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 -7 °C.
