Fragrant Virgin's Bower Care

Clematis flammula

A vigorous broom native to the Mediterranean that forms clouds of small, white, very fragrant (almond/vanilla) flowers in late summer and autumn. It loves full sun and well-drained soils; because it flowers on new shoots, it needs to be pruned hard at the end of every winter.

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 pruning is the end of the month.
  • General care: The silky seed heads left over from the previous season offer a decorative look.
February
  • Watering: Not needed; rainfall is sufficient.
  • Pruning: **CRITICAL PERIOD:** At the end of the month, just before the plant wakes up, prune very hard. Cut all stems to 30-60 cm above ground, leaving several pairs of buds on each stem. This is essential for abundant flowering.
  • General care: Clear away pruning debris and old leaves.
March
  • Watering: Usually rainfall is sufficient. Only newly planted saplings need watering.
  • Fertilizing: Apply a balanced fertilizer or well-rotted organic fertilizer once when it wakes from dormancy.
  • Pruning: Prune just before the shoots break. Because flowers form on this year's new shoots, hard pruning increases flowering.
  • Plant protection: Snails and slugs can damage the newly emerging shoots.
  • General care: Guide the newly emerging shoots onto the support system (wall, fence).
  • Pests & diseases: Snails and slugs are the biggest threat to fresh shoots.
April
  • Watering: If there is no rainfall, water every 15 days.
  • 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 plant grows very rapidly this month. Keep tying the shoots to the support system.
  • 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: Optionally, a potassium-heavy liquid fertilizer can be given once at the start of the month to encourage 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: 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.
  • 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 plant is preparing to flower, and buds are forming. Good air circulation is important.
  • 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.
  • Plant protection: The powdery mildew risk continues. Use a sulfur-based fungicide if necessary.
  • General care: Flowering begins and intensifies toward the end of the month.
  • Pests & diseases: Continue checking for powdery mildew.
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.
  • General care: Flowering reaches its peak.
September
  • Watering: If there is no rainfall, water once a week.
  • Pruning: Not needed; enjoy the flowers.
  • Plant protection: Powdery mildew is still a risk because of the humid nights. Use a suitable fungicide if necessary.
  • General care: The time when its strongly scented flowers are at their best. The faded flowers are replaced by silky seed heads.
  • Pests & diseases: Powdery mildew is the most common problem; ensuring good air circulation is important.
October
  • Watering: If there is no rainfall, water every 15 days.
  • General care: Flowering ends and the plant gradually prepares for rest. The silky seed heads take on a decorative look.
November
  • Watering: Not required; autumn precipitation is sufficient.
  • General care: Leaf fall begins.
  • Pests & diseases: Clearing fallen leaves prevents fungal diseases from carrying over to next year.
December
  • General care: The plant is in full dormancy. The seed heads remain on the stems through the winter.
