Hardy · -30 °C / -22 °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
  • Watering: Not needed; the soil should stay dry.
  • Pruning: During dormancy, do formative pruning and thinning pruning.
  • Plant protection: Dormant oil (mineral oil, at the labeled dose) against scale insects and spider mite eggs.
  • General care: Whitewash the trunks with lime (protection from sunburn and pests).
  • Pests & diseases: Dispose of pruned diseased branches.
  • Frost risk: Protect the root collar of young saplings with mulch.
February
  • Fertilizing: Well-rotted manure or compost can be mixed into the soil (1-2 kg/m²); do not overapply.
  • Pruning: While dormant, remove dry, broken, crossing and inward-growing branches so that air and light reach the inside of the crown. Prune during dormancy; encourage an open-center crown structure. As a fruit tree, prune annually from 4 years of age. Remove crossing and dense branches.
  • Plant protection: Just before the buds wake up, a copper-based preparation (Bordeaux mixture) against black spot and fire blight.
  • General care: If grafting is planned, scion wood is collected this month.
  • Pests & diseases: Check the trunk for pest entry holes.
  • Frost risk: Ongoing. Protect young seedlings.
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: Only remove frozen or broken branches.
  • Plant protection: If aphids are seen before flowering, apply an insecticide (e.g., deltamethrin).
  • General care: Suitable period for planting and transplanting. Flowering begins.
  • Pests & diseases: Watch for fire blight symptoms (blackening shoots).
  • Frost risk: If there is a frost risk during flowering, protect with smoke or a cover.
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.
  • Fertilizing: After flowering, apply a nitrogen-heavy fertilizer (e.g., ammonium nitrate) 50-100 g per tree, to the soil; do not overapply.
  • Pruning: Suckers (water sprouts) can be removed.
  • 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. Flowering continues.
  • 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: If there is no rainfall, water once a week.
  • Fertilizing: A foliar fertilizer containing micronutrients (zinc, boron) can be applied; do not overapply.
  • Pruning: Green pruning (tip pinching, thinning) can be done.
  • 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: Spread a 5-7 cm layer of mulch over the root zone; it retains soil moisture and suppresses weeds. Do not pile mulch against the trunk.
  • 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: 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.
  • Fertilizing: Fertilizing is not recommended; it can trigger excessive shoot growth.
  • 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: Continue clearing 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: 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.
  • Plant protection: If needed, continue red spider mite control.
  • General care: Keep watering intervals regular and prevent stress.
  • Pests & diseases: Check the trunk for sunburn and watch the leaves for signs of wilting.
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.
  • Plant protection: If there are signs of rust (Gymnosporangium), apply a fungicide (e.g. Difenoconazole).
  • General care: Hoeing can be done.
  • Pests & diseases: Watch for orange-yellow spots (rust) on the undersides of the leaves.
September
  • Watering: If there is no rainfall, water once a week.
  • Fertilizing: After harvest, a potassium- and phosphorus-heavy fertilizer (e.g. DAP or 5-15-30 NPK) can be applied at 150-250 g per tree; do not overdo it.
  • Pruning: Only if really necessary, broken branches are removed.
  • 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: Fruit is harvested and fallen fruit is collected.
  • 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: 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.
  • Fertilizing: The fertilizing season is over.
  • Plant protection: Fallen leaves should be collected and destroyed so they do not harbor disease. If disease is observed, apply treatment.
  • General care: Good time for planting and transplanting.
  • Pests & diseases: Check the trunk and branches for overwintering pests (such as scale insects) that could affect next year.
November
  • Watering: Water a newly planted specimen more often than established plants during its first year, as its root system is still shallow.
  • Pruning: Winter pruning can begin after leaf fall has completely ended.
  • Plant protection: Apply Bordeaux mixture after leaf fall (against bacterial and fungal diseases).
  • General care: Good time for planting and transplanting. Collect fallen leaves; many disease agents and pests overwinter under them.
  • Pests & diseases: Take measures against root damage from rodents such as mice.
  • Frost risk: Protect the root collar of young saplings by wrapping it with soil, mulch or sacking.
December
  • Pruning: Continue winter pruning (shaping, thinning).
  • Plant protection: If the air temperature is above 5°C, dormant oil can be applied.
  • General care: Disinfect your pruning tools.
  • Pests & diseases: Check the trunk and branches for moss or lichen growth (it is usually harmless).
  • Frost risk: Continue protecting young saplings from frost.
