Red Tip Photinia Care

Photinia × fraseri 'Red Robin'

A very popular evergreen shrub with bright red new shoots. It grows fast and responds very well to pruning, so it is used especially as a hedge and screening plant. For the most vivid red color it likes full sun and fertile, well-drained soil.

Half-hardy · -15 °C / 5 °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 required; winter precipitation is sufficient.
  • Pruning: A hard rejuvenation pruning can be done for very old hedges that have lost their form.
  • General care: Dormancy period.
  • Pests & diseases: The spores of the leaf spot disease (Entomosporium maculatum) overwinter in fallen leaves, so keep the base of the plants clean.
  • 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 -15 °C.
February
  • Pruning: Not needed. Wait until after flowering for the main pruning.
  • General care: Rest period continues.
  • 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 -15 °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: 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: Prune just before the shoots break. Because flowers form on this year's new shoots, hard pruning increases flowering. Prune when the leaves begin to lose their red color; this encourages the formation of new red shoots. During the dormant period, do thinning pruning to improve air circulation. When heavy pruning is needed, it is done during the growing season.
  • 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: During humid and cool periods, monitor the leaves and trunk for signs of mold, spots and rot.
  • Frost risk: Young shoots may be affected by severe late frosts.
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: If flowering is not wanted, it can be pruned at the end of the month to encourage new red shoots.
  • 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 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.
May
  • Watering: If there is no rainfall, water once a week.
  • Pruning: Main pruning time. After flowering, prune the plant (especially hedges) into the shape you want. This pruning encourages abundant new red foliage.
  • 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 continues. Spread mulch 5-7 cm thick over the root zone; it conserves 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. Water around the roots to a depth of 15-20 cm.
  • Pruning: Lightly trim to maintain the hedge form.
  • 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 new shoots mature and turn green.
  • Pests & diseases: Look for white, powdery spots on the leaves (powdery mildew). Thinning dense branches to increase airflow slows its spread. 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. Water around the roots to a depth of 15-20 cm.
  • Pruning: For a second flush of red shoots, one more light pruning can be done at the start of the 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: Water stress during the hottest period can weaken the plant and make it susceptible to disease.
  • Pests & diseases: Look for white, powdery spots on the leaves (powdery mildew). Thinning dense branches to increase airflow slows its spread.
August
  • Watering: Water deeply twice a week; prefer infrequent and generous watering over small and frequent. Water 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: Growth slows.
  • Pests & diseases: Look for white, powdery spots on the leaves (powdery mildew). Thinning dense branches to increase airflow slows its spread.
September
  • Watering: If there is no rainfall, water once a week.
  • Pruning: The last light corrective pruning of the season can be done at the beginning of the month. Late pruning encourages new shoots and exposes them to frost risk.
  • 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: Growth slows and the plant prepares for winter.
  • Pests & diseases: Look for white, powdery spots on the leaves (powdery mildew). Thinning dense branches to increase airflow slows its spread.
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.
  • Pruning: Do not prune.
  • 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: During humid and cool periods, monitor the leaves and trunk for signs of mold, spots and rot.
November
  • Watering: Water a newly planted specimen more often than established plants during its first year, as its root system is still shallow.
  • Pruning: Do not prune.
  • 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: During humid and cool periods, monitor the leaves and trunk for signs of mold, spots and rot.
  • Frost risk: Fresh shoots stimulated by late pruning are sensitive to frost.
December
  • General care: Evergreen leaves continue to lose water in winter. Water thoroughly once before the soil freezes.
  • 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 -15 °C.
