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; winter precipitation is sufficient.
  • Fertilizing: Never.
February
  • Pruning: While dormant, remove dry, broken, crossing and inward-growing branches so that air and light reach the inside of the crown. Cut in late autumn or early spring; check the underground root suckers several times a year. It has invasive potential: limit its spread to neighboring plants.
  • General care: Pull up unwanted seedlings and root suckers.
  • Pests & diseases: Keep in mind how aggressive the root system can be.
  • Frost risk: None; it is frost tolerant.
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.
  • General care: Good time for planting and transplanting.
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: Last chance to finish winter pruning. Cut branches that climb over other plants.
  • 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.
  • Frost risk: None; it is frost tolerant.
May
  • Watering: If there is no rainfall, water once a week.
  • Fertilizing: Never.
  • 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: 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.
June
  • Watering: Water deeply twice a week; prefer infrequent and generous watering over small and frequent. The area around the roots should be wetted to a depth of 20-30 cm.
  • Pruning: Start checking the new shoots. Prune right away those heading in unwanted directions.
  • 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 begins.
  • 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.
July
  • Watering: Water deeply twice a week; prefer infrequent and generous watering over small and frequent. The area around the roots should be wetted to a depth of 20-30 cm.
  • Fertilizing: Never.
  • General care: Flowering continues. Keep it in a position sheltered from midday sun; scorching at the leaf edges is a sign of burn.
August
  • Watering: Water deeply twice a week; prefer infrequent and generous watering over small and frequent. The area around the roots should be wetted to a depth of 20-30 cm.
  • Pruning: Continue pruning regularly (every 2-3 weeks) to keep growth under control.
  • General care: Flowering continues.
  • Pests & diseases: Watch out for leaf spot diseases.
September
  • Watering: If there is no rainfall, water once a week.
  • Fertilizing: Never.
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.
