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.
  • Plant protection: If necessary, you can apply dormant oil at the end of the month to control scale insects and aphid eggs.
  • Pests & diseases: Check the branches for overwintering pests.
February
  • Watering: Not needed; rainfall is sufficient.
  • Pruning: Late month, before the plant wakes up, is the ideal time for rejuvenation and shape pruning. Remove dry, diseased and crossing branches.
  • Plant protection: Applying Bordeaux mixture after pruning can help prevent fungal diseases.
  • General care: Clear away pruning debris. Propagation from hardwood cuttings can be carried out.
  • Pests & diseases: Carry out a general condition check.
March
  • Watering: If there is no rainfall, 1-2 times a month (10 L/m²). New plantings should be watered more often.
  • Fertilizing: Sprinkle slow-release balanced NPK (15-15-15) granular fertilizer (40-50 g per m²) or well-rotted manure onto the soil surface and mix it into the soil (do not overapply).
  • Plant protection: Check the new shoots for aphids.
  • General care: Clear the weeds and hoe the root zone.
  • Pests & diseases: If you see aphids on fresh shoots, take action.
April
  • Watering: In periods without rainfall, every 15 days (15 L/m²).
  • Pruning: After flowering (usually this month), a light shaping pruning can be done. Avoid deep pruning so as not to interfere with fruit set.
  • Plant protection: If there are signs of rust (orange spots on the leaves), use a copper-based fungicide.
  • General care: Hoe.
  • Pests & diseases: Monitor the leaves for rust and powdery mildew.
May
  • Watering: In periods without rainfall, every 15 days (15 L/m²).
  • Pruning: Cut only branches that spoil the appearance.
  • Plant protection: Continue checking for aphids and rust disease.
  • General care: The fruits begin to form.
  • Pests & diseases: Be watchful for leaf spot diseases.
June
  • Watering: In a long drought, water deeply once a month.
  • Fertilizing: None; do not fertilize in the heat.
  • Pruning: Not required; only remove broken 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: Spreading mulch (bark, etc.) over the root zone reduces water loss.
  • Pests & diseases: Look for white, powdery spots on the leaves (powdery mildew). Thinning dense branches to increase airflow slows its spread.
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. Water the area around the roots to a depth of 15-20 cm.
  • Pruning: Prune as soon as flowering ends. Next year's flower buds form over the summer; late pruning reduces flowering.
  • 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: Monitor the development of the fruits.
  • Pests & diseases: Look for white, powdery spots on the leaves (powdery mildew). Thinning dense branches to increase airflow slows its spread.
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. Water the area around the roots to a depth of 15-20 cm.
  • 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: Look for white, powdery spots on the leaves (powdery mildew). Thinning dense branches to increase airflow slows its spread.
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: The fruits ripen (turn black) and can be harvested. The leaves begin to change color.
  • Pests & diseases: Look for white, powdery spots on the leaves (powdery mildew). Thinning dense branches to increase airflow slows its spread.
October
  • Watering: Not needed; rainfall is sufficient.
  • General care: After leaf fall is complete, collect the fallen leaves around the plant to prevent diseases from overwintering.
  • Pests & diseases: Clear away plant debris from the surrounding area.
November
  • Watering: Not needed; rainfall is sufficient.
  • General care: Collect fallen leaves; many disease agents and pests overwinter under leaves.
  • Pests & diseases: General check.
December
  • Watering: Not needed; rainfall is sufficient.
  • General care: Winter dormancy continues. Make next year's pruning and fertilizing plan.
  • Pests & diseases: Check branches for scale insects.
