Silver Birch Care

Betula pendula

A deciduous tree known for its white trunk that likes cool, humid climates. In hot, dry climates like Izmir it becomes stressed, and regular deep watering is critical for its survival.

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: If there is no rainfall, water deeply once a month (50-60 L/m²).
  • Pruning: Not required, avoid pruning during this period to prevent spring sap flow (bleeding).
  • Plant protection: Applying dormant oil to the trunk and branches controls scale insect and aphid eggs.
  • General care: Clean up fallen leaves and branches.
  • Pests & diseases: Check the trunk bark for overwintering pests.
February
  • Watering: If rainfall is not sufficient, water deeply once a month (50-60 L/m²).
  • Pruning: Absolutely do not prune; sap flow is very heavy.
  • General care: Clean the area around the root collar.
  • Pests & diseases: Carry out a general condition check.
March
  • Watering: If rainfall is insufficient, water deeply every 15 days (40-50 L/m²).
  • Fertilizing: At the start of the month, apply a slow-release balanced NPK (15-15-15) or acidic soil fertilizer, and plenty of compost (do not overapply).
  • Pruning: Absolutely do not prune.
  • Plant protection: Check the new shoots for aphids. To control the bronze birch borer (a trunk pest), a systemic soil-applied insecticide (e.g., imidacloprid) may be considered (consult a licensed plant-protection supplier or an agronomist).
  • General care: Spread a 10 cm layer of mulch (pine bark, etc.) to keep the root zone cool and retain moisture.
  • Pests & diseases: Watch out for birch leaf miner and aphids.
April
  • Watering: If there is no rainfall, water every 15 days.
  • Pruning: Absolutely 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: Maintain the mulch layer.
  • 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.
  • 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 root zone should be wetted to a depth of 30-40 cm.
  • Fertilizing: None; do not fertilize in the heat.
  • Pruning: Do shaping and hedge pruning.
  • 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: Try to keep the root zone shaded and cool.
  • 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 root zone should be wetted to a depth of 30-40 cm.
  • Plant protection: Keep checking regularly for signs of wood borer (D-shaped holes in the trunk, dieback at the top).
  • General care: Leaf scorch and leaf drop may occur during extreme heat; watering is essential to reduce this stress.
  • Pests & diseases: Watch for signs of stress (leaf yellowing, wilting).
August
  • Watering: Water deeply twice a week; prefer infrequent and generous watering over small and frequent. The root zone should be wetted to a depth of 30-40 cm.
  • Pruning: Yes, this is the best time for pruning. Sap flow has slowed. Remove dry, diseased, weak and crossing branches.
  • General care: Do not stop watering; it is important for the tree to enter winter strong.
  • Pests & diseases: During pruning, check the trunk for borer holes or sawdust-like debris.
September
  • Watering: If there is no rainfall, water once a week.
  • Pruning: Do the last formative pruning of the season; do not let it put out new shoots before frost.
  • General care: The leaves begin to turn yellow and fall.
  • Pests & diseases: Collect fallen leaves to prevent the spread of fungal diseases.
October
  • Watering: If there is no rainfall, water every 15 days.
  • General care: After leaf fall ends, clear all the leaves under the tree.
  • Pests & diseases: Clearing the leaves prevents diseases such as leaf spot from recurring next year.
November
  • Watering: Not needed; rainfall is sufficient.
  • General care: Collect fallen leaves; many disease agents and pests overwinter under leaves.
  • Pests & diseases: Check the trunk and branches in general.
December
  • Watering: If rainfall is very insufficient, give a small amount when the soil dries out.
  • Pruning: Remove dead/damaged branches; do not prune heavily.
