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.
- Pruning: Not needed. The best time for the main pruning is the end of the month or early March.
- General care: Clean up fallen leaves and seed pods.
- 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 -12 °C.
February
- Watering: Not needed; rainfall is sufficient.
- Pruning: At the end of the month or the beginning of March, before the plant wakes up, hard pruning can be done. Cutting the plant back to 30-60 cm above ground gives a fuller form and abundant flowers.
- General care: Clear away pruning debris. Cut out frost-damaged or dried 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 -12 °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: After pruning, you can apply slow-release balanced NPK (e.g., 10-10-10) fertilizer or compost to the soil, though it is not required (do not overapply).
- Pruning: Prune just before the shoots break. Because flowers form on this year's new shoots, hard pruning increases flowering. Before growth starts, dead branches are cut. Upper parts damaged by hard frosts are pruned back to live wood. Because it flowers on new growth, spring pruning is appropriate.
- General care: Good time for planting and transplanting.
- Frost risk: Newly emerging shoots may be affected by late frosts, but the plant recovers quickly.
April
- 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: 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: You can cut only the faded flower clusters to encourage new flowering (optional).
- 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: 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: In a long drought, water deeply once a month.
- Pruning: Deadheading extends the flowering period.
- 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: 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.
- General care: Flowering continues.
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.
- General care: Flowering continues.
September
- Watering: In a long drought, water deeply once a month.
- General care: Flowering continues.
October
- Watering: Reduce watering to once a month. Stop completely if the rains begin.
- General care: Flowering slows down and ends. The plant prepares to shed its leaves.
November
- Watering: Not required; autumn precipitation is sufficient.
- General care: In winter precipitation, make sure water does not collect in the root zone; for this plant, drainage is more critical than watering. Collect fallen leaves; many disease agents and pests overwinter under the leaves.
- Pests & diseases: Removing plant debris prevents possible diseases from overwintering.
- Frost risk: Protect young plants during their first winter by mulching around the root collar.
December
- General care: The plant is in full dormancy.
- 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 -12 °C.
