Garden Care Guide

Silver Maple Care

Acer saccharinum

A very fast-growing large tree with silvery-white leaf undersides. It likes moist to wet soil, but because of its weak, brittle branch structure and aggressive surface roots it is easily damaged in storms; it is therefore not recommended for residential areas and narrow gardens.

Hardy · -25 °C / -13 °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
  • Pruning: This is the most critical time for safety. Structural pruning should be done to remove weak, narrow-angled branches prone to breaking and dead wood. Professional help is strongly recommended because of the tree's size.
  • General care: Check drainage.
February
  • Pruning: Finish pruning before the buds swell.
  • General care: Planting is not recommended, but if necessary, it can be done while the soil is not frozen.
March
  • Watering: Water a newly planted specimen more often than established plants during its first year, as its root system is still shallow.
  • Fertilizing: Not needed; it grows very fast.
  • General care: Suitable period for planting and transplanting. Flowering begins.
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: Surface roots can easily be damaged by the lawn mower; be careful.
  • 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: Do not prune 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: 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.
  • Pruning: Do shaping and hedge pruning. Its branches are brittle and break easily in storms. Its roots are shallow and can lift pavements and infrastructure; plant it away from structures and do not prune while the sap is flowing.
  • 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 risk of branch breakage is high in summer storms.
  • 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.
  • General care: Aggressive roots can grow into water pipes and sewers; do not plant it close to buildings.
  • Pests & diseases: Be watchful for signs of Verticillium wilt (sudden branch dieback).
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.
  • General care: Monitor the condition of the tree after heat stress.
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: Visually check the tree's branches before autumn storms. Remove unwanted seedlings that have sprouted from its own seeds.
October
  • Watering: If there is no rainfall, water every 15 days.
  • General care: Autumn colors, which are usually pale yellow, are not very striking.
  • Pests & diseases: Clear fallen leaves.
November
  • 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 begin winter pruning after the leaves have completely fallen. Safety-oriented pruning is essential.
  • General care: Good time for planting and transplanting. Collect fallen leaves; many disease agents and pests overwinter under them.
December
  • Pruning: This is an ideal month for pruning. Consulting a professional arborist is the safest option.
  • General care: The tree is dormant.
  • Frost risk: It is very cold hardy.
